Solana Wallets & Identity Apps

Dfns provides one of the most comprehensive wallet-as-a-service platforms on Solana, enabling applications to seamlessly create and manage digital asset wallets at scale. Their API-first approach allows developers to embed both custodial and non-custodial wallet functionality directly into their applications, with support for secure user onboarding and transaction management across multiple blockchains including Solana.The platform stands out for its enterprise-grade security features and flexible deployment options, including cloud-managed, hybrid, and on-premises models. Their entitlement management system provides granular control over wallet permissions and transaction policies, making it ideal for businesses that need to maintain strict security and compliance standards while managing digital assets at scale.

In the privacy and security space, Kulipa Card Issuance API implements advanced zero-knowledge technology to protect user transaction data while maintaining regulatory compliance. The platform's architecture ensures that sensitive payment information and user data are handled with the highest level of security, while still enabling seamless transaction processing through traditional payment rails.Their privacy-focused approach extends to their KYC verification system, which maintains user confidentiality while meeting regulatory requirements. The self-custodial nature of their wallet integration ensures users maintain control over their funds, while the zero-knowledge proofs enable secure transaction verification without exposing sensitive details. This combination of features makes it a standout solution for privacy-conscious users who want to use crypto for everyday payments.

Nomadz assigns each user a Nomad ID, a Solana-native identity built on Metaplex Core that functions as a composable travel passport. Each accommodation booking adds a verified trip record to the on-chain profile, accumulating into a permanent history of travel that is legible to other protocols, communities, and event organizers within the Solana ecosystem. The Nomad ID tracks experience points, earned badges, and achievements, making travel history portable across applications. The system was built with a Metaplex DAO grant specifically for on-chain identity and progression mechanics, with an updated version powered by Metaplex Core shipping in November 2025. By early 2026, the platform had over 1,000 active on-chain profiles representing verified travel records.

Privacy is a foundational design principle in Cake Wallet rather than an optional feature layer. The wallet requires no account, no email address, and no identity verification at any point in its core functionality — private keys are generated and stored exclusively on the user's device with no server-side component. Tor routing is available natively within the app, channeling traffic through the Tor network to mask IP addresses from node operators. This combination of zero-account setup and native Tor support reflects the wallet's origins as the first iOS Monero wallet in 2018, built explicitly for privacy-preserving transactions. Cake Wallet extends this privacy architecture across Bitcoin and Zcash as well. Bitcoin support includes Silent Payments, which generate one-time addresses that prevent address reuse tracking, and PayJoin v2, which breaks the common-input-ownership heuristic used by blockchain analytics services. Zcash defaults to shielded z-addresses rather than transparent addresses — the technically correct default for Zcash privacy, though not universally adopted by wallets that carry ZEC. Lightning Network support, added in March 2026, keeps transaction data off public block explorers by default and does not embed the user's Spark address in Lightning invoices, deliberately limiting on-chain visibility for routine payments.

ZenGo integrates biometric authentication as a core layer of both wallet access and account recovery. The wallet's FaceLock feature uses facial recognition to verify user identity during the recovery process, working alongside email verification and an encrypted backup file stored in iCloud or Google Drive to form a multi-factor recovery system. Because the biometric check is one component of a layered recovery model built on MPC cryptography, compromising any single factor is insufficient on its own to gain wallet access. This design ties authentication to the physical user rather than a transferable secret like a password or seed phrase. ZenGo has reported no successful wallet hacks since its 2018 launch, a record it attributes to the combination of MPC key distribution and this layered biometric authentication approach across its 2 million-user base.

Web3.bio aggregates verifiable credentials from nine major data sources covering more than 10 million records, rendering attestations as visible badges on public identity profiles. Providers include Dentity, Justaname, Binance KYC, Coinbase KYC, and the Human Passport reputation score. Known compromised accounts receive a warning badge, giving the credential display a trust-signaling function beyond simple attestation. Developers gain programmatic access to this credential data through a Credentials API launched in late 2025. A partnership with Sign protocol in April 2025 expanded the credential scope to include NFC passport scanning and Plaid banking confirmation, and introduced credential-gated token distributions that allow projects to airdrop tokens based on verifiable attributes without exposing underlying private data.

KAIO's compliance engine is built into the protocol layer, checking every transaction against jurisdictional rules and investor-level requirements before execution rather than as an external post-processing step. The platform uses RISC Zero's zkVM to generate onchain investor credentials that confirm eligibility for participation without publishing underlying personal data on-chain — an approach designed to satisfy regulatory requirements while preserving DeFi composability. All access to KAIO's institutional fund products is gated by KYC/KYB onboarding, and subscription and transfer logic enforces jurisdictional and investor-eligibility rules automatically at the smart contract level. This privacy-preserving credential infrastructure is central to KAIO's strategy of operating across multiple regulatory regimes simultaneously. The platform operates under ADGM's framework in Abu Dhabi, with Conduit Asset Management holding a Capital Markets Services License from Singapore's Monetary Authority, and fund vehicles typically domiciled under CIMA frameworks. By generating verifiable investor credentials onchain without exposing personal data, KAIO can serve accredited and qualified institutional investors across supported jurisdictions while remaining composable with DeFi protocols that do not themselves have access to investor identity data.

WalletConnect Network is the primary open protocol enabling wallets to connect to decentralized applications across more than 100 blockchains, including Solana, Bitcoin, and EVM chains. When a user scans a QR code or clicks a deep link, the protocol creates an end-to-end encrypted session through WalletConnect relay network, allowing the wallet to sign transactions for dApps without exposing private keys to the application. Over 700 wallets have integrated WalletConnect, including Phantom, Backpack, and Solflare on Solana, making it the dominant connectivity standard across the wallet ecosystem. WalletKit, one of WalletConnect two core SDKs, provides wallet developers with the integration layer needed to receive and handle session requests from any WalletConnect-enabled application. Alongside traditional wallet connections, AppKit surfaces email and social login as alternative identity pathways, broadening wallet-centric authentication options for application developers. With 4.1 million unique active wallets served and 179 million wallet-to-app connections facilitated by 2024, WalletConnect has established itself as the core infrastructure linking wallets to the broader Solana and multi-chain dApp ecosystem.

Unlimit Crypto bundles KYC verification, AML checks, and fraud detection into its embedded ramp service, relieving integrating platforms of the compliance overhead that typically accompanies fiat-to-crypto conversion. Developers connecting through its single API inherit these compliance layers rather than sourcing or building them separately, reducing time to production and ongoing regulatory maintenance across multiple jurisdictions. KYC is modular within the platform, meaning integrators can configure the level of identity verification applied to their users based on their own compliance requirements. This flexibility makes Unlimit Crypto relevant for Solana-based projects operating across diverse regulatory environments including Europe, Latin America, India, Africa, and Asia-Pacific, where AML and identity requirements differ significantly by country.

Crystal Intelligence provides AML screening infrastructure used by VASPs, banks, and payment providers to meet anti-money laundering obligations across 330-plus blockchains including Solana. OFAC, EU, and UN sanctions lists are refreshed every 15 minutes, and goAML-compatible reports enable audit-ready submissions to regulators, making Crystal a foundational layer for compliant digital-asset operations. The platform's risk-scoring engine attributes transactions to 118,000-plus verified entities—exchanges, darknet markets, and sanctioned addresses—and triggers configurable alerts before risky funds settle. Crystal for Compliance is purpose-built for MiCA, MAS, and VARA regimes; Ukraine Cyber Police have used the platform since 2021 to build court-admissible evidence, and Dubai's DIFC Courts approved it as an official forensics provider in 2026.

Mixin Messenger implements the Signal Protocol for end-to-end encrypted messaging, integrating communication privacy directly into a cryptocurrency wallet application. This design means conversations and asset transfers share the same encrypted channel, rather than requiring separate applications for messaging and financial activity. The authentication model — phone number plus PIN rather than a seed phrase — reduces onboarding complexity while the TIP protocol and secure enclave storage maintain cryptographic key security. Rate limiting on PIN attempts provides a technical safeguard against brute-force attacks on the authentication layer. The TIP (Throttled Identity Protocol) distributes key fragments across a Password Network and Signer Network, ensuring no single server holds enough information to reconstruct a user's private key. Users can export a full mnemonic phrase and private key at any time, preserving self-custody and the ability to migrate away from Mixin if the platform becomes unavailable. This approach balances ease of use — no seed phrase required for standard operation — with the privacy and custody guarantees of a non-custodial architecture. In August 2026, Mixin's published commentary on the COLDCARD entropy incident reinforced the platform's public commitment to diverse, independent key generation as a security-through-diversity principle.

SolMail implements self-sovereign identity at the protocol level by making every Solana wallet address a valid, operator-independent inbox by default. Users can extend this with Solana Name Service handles, .mail domains, or email-style addresses — all minted as on-chain NFTs that are tradable and explicitly not revocable by any operator. This design ensures that identity ownership remains entirely in the hands of the user rather than any centralized service provider. The identity layer anchors the broader SolMail architecture: end-to-end encrypted messaging via ElGamal cryptography, file attachments stored through Irys decentralized storage, and the Fusion NFT mail format that embeds payments and contracts inside messages. Because addresses are on-chain assets, SolMail identities can serve as SSO credentials across Solana dApps and as the authentication layer for programmable Web3 workflows. The protocol explicitly positions these self-sovereign identities as a potential identity primitive for the Solana ecosystem.

Passkeys Wallet is an embedded, self-custodial wallet delivered as a developer SDK by Exodus Movement, a publicly traded company (EXOD on NYSE American). Unlike browser extension wallets, it requires no installation and no seed phrase; users create a wallet through a single browser popup secured by biometric authentication via WebAuthn. The SDK supports Solana, Bitcoin, Ethereum, and more than a dozen other chains from a single integration, making it a broad-coverage wallet option for multi-chain applications. The wallet is designed to appear directly within the host application rather than as a separate product, giving developers control over branding and UX while Exodus Movement handles key management infrastructure through a multi-party computation architecture. The SDK ships integration recipes for the Solana Wallet Adapter, Wagmi, RainbowKit, and Viem, enabling existing dApp scaffolding to add passkey wallet support with minimal code changes. Partnership integrations since the July 2024 launch include Blockchain.com and M80, an esports organization.

Braavos is a self-custodial smart contract wallet built on Starknet with over one million deployed accounts, offering hardware-bound transaction signing through device Secure Enclave integration and up to three-factor authentication. Its account abstraction architecture — where each user wallet is a unique programmable smart contract — supports customizable spending limits, multi-owner accounts with threshold signing, and biometric approval without external hardware. For Solana users, Braavos provides an onramp into Starknet's DeFi ecosystem: Solana is among 21 supported source chains, enabling direct asset transfers from Solana into Braavos-managed positions. The wallet surfaces native staking for ETH, STRK, and Bitcoin, built-in DEX swaps through AVNU aggregation, fiat on-ramps via Apple Pay and Google Pay, and Lightning Network payment support — all without leaving the app.

Zo treated the Solana wallet as its native identity layer: every user's wallet address functioned as their Zo identity, making the application simultaneously a Solana wallet and a Web3 messaging platform. This wallet-as-identity model enabled cross-chain payment functionality directly inside group conversations, allowing users to send assets and trigger smart contract interactions from within a chat interface. Zo is no longer operational as of mid-2026. The zo.me domain fails to resolve, the platform's mobile and web applications are unreachable, and no official shutdown announcement has been located in public sources. The project is documented here as part of the Solana consumer wallet and identity application history from the 2023–2024 cohort.

SollPay replaces the traditional seed phrase with a self-sovereign identity model built on zero-knowledge proofs and Solana account abstraction. At signup, a user's phone number or email is hashed with the Poseidon algorithm to create a unique, privacy-preserving identifier, which is verified on-chain without exposing the underlying contact information. Private keys live exclusively in device-level secure hardware and are never held by SollPay or any third party. Three custom on-chain programs — a Wallet Factory, a Wallet Program, and an Administration Program — manage wallet creation, transaction processing, and the mapping from hashed identifiers to wallet addresses. Recovery on a new device follows a ZK re-authentication flow rather than requiring a mnemonic backup. This architecture allows users to maintain genuine self-custody while accessing their wallet with the same credentials used for everyday applications.

Edge's security model is a zero-knowledge architecture in which all private key generation and encryption happens on the user's device before any data reaches Edge's servers—meaning Edge cannot access user funds even under legal compulsion or a server breach. In February 2026, Edge deepened its privacy posture by integrating the NYM Mixnet at the network layer, routing wallet traffic through a decentralized mix network that conceals IP addresses and transaction timing patterns from internet service providers and surveillance infrastructure. The wallet provides official support for Monero (XMR), endorsed by the Monero team, and Zcash (ZEC), including the Ironwood network upgrade and Zcash Private Payment Names. These three layers—device-level key protection, network-level metadata obfuscation, and on-chain privacy coin support—make Edge one of the more comprehensive privacy-tools offerings in the mobile wallet space.

Solana Mobile built its Seed Vault as a hardware-backed security boundary that stores private key material in a trusted execution environment isolated from the Android OS, ensuring seed phrases and private keys are never exposed to system software or applications. Transaction signing is completed locally inside the Seed Vault, with biometric authentication gating each authorization before a signed output is returned to the requesting app. The Seeker integrates a power-button fingerprint sensor directly tied to the Seed Vault, and a double-tap gesture on the power button enables quick transaction approvals without unlocking the full device. The Mobile Wallet Adapter protocol routes signing requests from dApps into the Seed Vault, keeping key material inaccessible to application code at all times. This architecture means users authenticate and authorize transactions entirely on-device using biometrics, without relying on software wallets, browser extensions, or externally stored credentials. The biometric-first approach to transaction authorization defines the Solana Mobile security model across both the first-generation Saga and the Seeker.

Ping Network provides decentralized VPN routing and residential proxy access through a global network of contributor nodes on Solana. Server nodes — dedicated hardware run by operators — are optimized for high-throughput VPN routing and enterprise traffic management, while edge nodes supply residential IP addresses sourced from real consumer devices rather than data centers. The platform's proxy pool spans over 190 countries and offers four proxy types — Mobile, Data Center, ISP, and Residential — priced from $0.30 per GB, with access available via a dashboard and API. Because residential and mobile proxy addresses originate from genuine consumer devices rather than identifiable data center ranges, they are substantially harder for target sites to block — a meaningful advantage for enterprise use cases such as AI training data collection, ad fraud verification, and competitive price monitoring. The decentralized architecture eliminates the single points of failure present in centralized VPN and proxy providers. Security measures include end-to-end encryption of user traffic, client authorization verification at the node level, and on-chain slashing penalties for validators that submit fraudulent proofs or fail to maintain uptime.

NetSepio Erebrus protocol is a decentralized VPN that replaces centralized server infrastructure with a peer-operated node network, removing single points of control and enabling censorship resistance across the internet. The protocol supports three distinct transport modes to accommodate different threat environments: WireGuard for standard fast-path connectivity, VLESS with the REALITY stealth carrier to disguise VPN traffic as normal HTTPS and bypass deep-packet inspection in restrictive networks, and Hysteria2 for QUIC-based connectivity with optional obfuscation under high-latency or congested conditions. A companion dWiFi product extends VPN-grade protection to public wireless networks with an added firewall layer for users on untrusted hotspots. Erebrus launched mobile applications in November 2024 on Android and iOS and became available on the Solana dApp Store, allowing Solana Mobile device owners to activate subscriptions through their blockchain-native devices. The protocol is built around strict data minimization: it does not log traffic content, destination IPs, DNS queries, or connection records, transmitting only bandwidth metadata and online-time for billing. This privacy architecture, combined with protocol flexibility across three transport modes, positions Erebrus for users who require genuine censorship circumvention rather than basic privacy alone.

Deskoin completes account creation and identity verification in under five minutes, making AMF-regulated crypto access practical for non-technical French investors. As a MiCA-authorized CASP overseen by both the AMF and ACPR, it applies compliant identity checks across custody, exchange, and order execution services. The fast onboarding reflects the founding team's goal of meeting formal financial compliance standards without unnecessary friction. For corporate clients, Deskoin Pro includes a Know Your Business (KYB) process typically completed within 72 hours, enabling SMEs and professional investors to access treasury management, OTC trading, and the Deskoin Flows crypto-to-fiat conversion service. KYB completion is required before business features become accessible. Trustpilot reviews from over 183 users frequently cite smooth onboarding, indicating the compliance framework does not create excessive friction.

Unruggable gives Solana users a self-sovereign key custody solution designed around Solana's account model and transaction structure. Private keys are generated and stored offline in the hardware device, never exposed to internet-connected software, and controlled entirely by the user through physical interaction. General-purpose hardware wallets treat Solana as one of many chains; Unruggable is built exclusively for Solana users from the ground up. The companion app extends self-custody into the broader Solana ecosystem. Squads multisig is built directly into the app, letting users require multiple signers before any transaction proceeds and eliminating single points of failure. Solana Name Service integration provides human-readable address resolution within the secure environment. The open-source firmware and app give users full auditability over every layer of their key management stack.

encryptSIM provides a privacy-first eSIM service that separates mobile connectivity from identity — no government ID, no SIM registration, and no data retention by the provider. Network access routes through infrastructure in Sweden, where telecoms law does not require subscriber metadata retention, making the privacy guarantee structural rather than a policy promise. Users access over 1,000 regional plans across 210 destinations without submitting personal identification. The project extends its privacy design to the payment layer. While SOL, ETH, and USDC are accepted at checkout, the team acknowledges public on-chain records do not guarantee anonymity and has announced private payments using the native $ESIM token to obscure sender, amount, and transaction context. A decentralized VPN integration in development will bundle network-layer protection into plans, completing a privacy stack across mobile identity, connectivity, and payment.

BlockSec's Phalcon Compliance is an AML/CFT platform offering wallet screening, Know Your Asset (KYA), and Know Your Transaction (KYT) capabilities across more than 600 million labeled addresses with over 200 risk signals. The platform holds AICPA SOC 2 compliance, is GDPR ready, and is designated as a trusted partner by financial regulators. In December 2025, Phalcon Compliance 3.1 introduced a search-first workflow enabling KYT screening without pre-payment, demo-driven onboarding, or account registration. The client base spans crypto-native exchanges, traditional finance firms, and public sector bodies. Notable compliance clients include Coinbase, Bybit, Crypto.com, PwC, the United Nations, the FBI, and Hong Kong's Securities and Futures Commission. Alongside the compliance platform, MetaSleuth provides cross-chain forensic investigation for post-incident asset tracking and regulatory monitoring, serving over 500 clients. BlockSec positions itself at the intersection of security research and financial crime prevention, responding to what it describes as a rapidly evolving regulatory landscape in digital assets.

MetaMask is one of the most widely adopted self-custody wallets in crypto, with over 100 million downloads and more than a decade of continuous operation since its 2016 launch by ConsenSys. In 2025, MetaMask expanded beyond its Ethereum roots with native Solana support in both its browser extension and mobile app, giving users the ability to create or import Solana accounts, automatically detect SOL and SPL token balances, and connect to Solana-based dApps without switching wallets. Private keys never leave the user's device, and the wallet applies its full security infrastructure to Solana — including real-time transaction simulation, malicious application detection, and MEV protection — on every interaction. For users already in the MetaMask ecosystem, accessing Solana is as straightforward as creating a new account within a familiar interface. The wallet supports sending, receiving, swapping, bridging, and buying Solana tokens natively, while the MetaMask Connect SDK and Embedded Wallets platform give dApp developers a documented integration path to reach MetaMask's existing user base on mobile and desktop. MetaMask's entry into Solana brings millions of users historically centered on Ethereum and EVM chains into contact with Solana-based protocols and applications through a wallet they already use daily.

OneKey is an open-source cryptocurrency wallet ecosystem offering both hardware cold storage devices and multi-platform software applications across mobile, desktop, and browser. Founded in 2020, it supports Solana across its full product range, covering SOL storage, SPL token management, NFT display, and in-app access to DeFi protocols. Hardware devices such as the OneKey Pro and Classic 1S use EAL6+ certified secure elements — matching the standard found in government passports — keeping private keys isolated from internet-connected software at all times. On Solana, OneKey hardware supports SOL message signing, enabling users to authenticate with dApps while keys remain cold. Confirmed integrations with Jupiter, Solflare, and Backpack let the hardware serve as a cold signing layer while a familiar front-end handles swaps and staking. Migration tools for Phantom and MetaMask, combined with a fully open-source codebase published on GitHub, make OneKey a transparent and practical option for Solana users seeking to add hardware-level key protection to their existing setup.

Encifher is a confidential computation protocol on Solana that hides wallet balances, trade amounts, and transaction details from the public ledger, addressing the fundamental privacy gap in Solana's fully transparent transaction model. The protocol replaces on-chain data with encrypted handles and moves computation into a trusted execution environment (TEE), completing confidential operations end-to-end in approximately 20 to 30 seconds. Launched in 2024 and backed by Alliance DAO, a Solana Foundation grant, and a Circle grant, it has served more than 5,000 users and processed over 50,000 confidential operations in production. Its security design layers three independent protections: TEE hardware attestation, threshold ElGamal encryption requiring a quorum of key holders for any decryption, and zero-knowledge proofs for on-chain transaction validation without revealing underlying values. Ephemeral accounts prevent observers from linking deposits to withdrawals by matching amounts or timing. The encryption layer runs at over one million operations per second, and threshold decryption completes in milliseconds, making Encifher one of the more performant privacy solutions built on Solana.

Guarda is a non-custodial, multi-chain cryptocurrency wallet that lets users store, swap, and manage digital assets across more than 70 blockchains — including Solana — from a single interface. Founded in 2017, it has earned a 4.2–4.3 out of 5 rating on Trustpilot from over 2,100 reviews, reflecting sustained user trust over nearly a decade. Private keys are generated locally on the user's device and never transmitted to Guarda's servers, making it a genuine self-custody solution. No account registration is required to create a wallet, and the same wallet is accessible across web, desktop, mobile, and browser extension surfaces using an encrypted backup tied to a user-set password. On Solana specifically, Guarda supports SOL storage, SPL token management, sending and receiving assets, fiat purchasing via Visa, Mastercard, or Apple Pay, and real-time portfolio tracking. The Chrome and Brave browser extension enables connection to Solana-based Web3 dApps, while Ledger Nano S and Nano S Plus integration lets users sign transactions with hardware-level key security — including during staking and swap operations. Mobile apps add biometric login via Face ID and Touch ID. For users managing crypto across multiple ecosystems who want a single, non-custodial interface that covers Solana alongside Bitcoin, Ethereum, and dozens of other networks, Guarda offers broad multi-chain reach with a long operating track record.

Spendly differentiated itself in the crypto card market through a no-KYC policy, allowing users to obtain and use a virtual Mastercard without submitting identity documents. This privacy-first approach made it appealing to cryptocurrency holders who valued transactional anonymity and wanted to avoid the disclosure requirements common at centralised exchanges and regulated card providers. The card supported Solana along with Bitcoin, Ethereum, Litecoin, and Tether, giving users across multiple chains a way to spend their holdings without identity verification. Supported payment channels included Apple Pay and Google Pay, enabling tap-to-pay in everyday contexts. The absence of KYC placed Spendly alongside a small category of privacy-oriented prepaid card products on Solana, including SolCard and SolvoCard, that competed on anonymity rather than features. Its custodial structure meant users transferred crypto to Spendly's systems for conversion — a trade-off that centralised control in exchange for frictionless access. No on-chain programs were deployed; the privacy benefit came from the off-chain product design rather than cryptographic privacy techniques. Spendly launched in June 2025 and discontinued operations by mid-2026, leaving the no-KYC card niche on Solana without one of its entrants.

LazorKit is open-source passkey smart wallet infrastructure for Solana that eliminates seed phrases in favor of device biometrics. Users create non-custodial wallets through a WebAuthn ceremony authenticated via Face ID, Touch ID, or Windows Hello, with the private key confined to the device's Secure Enclave and synced through iCloud Keychain or Google Password Manager. A Program Derived Account is derived from the passkey credential, so the same biometric maps to the same on-chain wallet address every time. The V2 on-chain program uses the Secp256r1 curve, the same elliptic curve as WebAuthn and Apple Secure Enclave, allowing passkeys to sign transactions directly on-chain at approximately 9,441 compute units per operation. Role-based access control structures wallet authority into Owner, Admin, and Spender tiers with strictly enforced hierarchical permissions and self-removal protection. Session keys are ephemeral Ed25519 signers derived from a single passkey prompt, supporting up to 16 immutable permission rules covering SOL spending caps, per-mint token limits, recurring window budgets, and program whitelists or blacklists. Sessions expire by absolute slot with a maximum of 30 days and consume 4,483 to 5,983 compute units versus 9,441 for full passkey operations. The V2 program completed a security audit by Accretion with all 17 identified issues resolved before mainnet deployment.

FoxWallet is a non-custodial Web3 wallet where seed phrases and private keys are encrypted locally and never transmitted to any server or third party. Users create or import wallets via 12- or 24-word recovery phrases, with cryptographic material remaining exclusively on-device. This self-sovereign design covers Solana alongside 100+ other chains, giving users unified custody over a broad portfolio without fragmentation. The wallet's identity security model adds three reinforcing layers beyond basic non-custody: a continuously updated blacklist of phishing domains and malicious contract addresses, explicit warnings with decoded transaction data for high-risk actions, and a CertiK penetration test completed in November 2021 that returned zero findings. FoxWallet holds a CertiK Skynet score of 86.58 (AA rating), reflecting ongoing monitoring of code activity and on-chain behavior.

TokenPocket is a self-custody multi-chain wallet founded in 2018, with over 30 million users across 200+ countries and support for 200+ blockchain networks. Private keys are generated and stored locally on the user device — no third party holds custody. For Solana users, the wallet manages SOL and any SPL token, handling associated account creation automatically and explaining the two-part fee structure of transaction fees plus rent. Security architecture goes beyond local key storage: TokenPocket offers MultiSig wallet support requiring multiple authorizations per transaction, and an Account Abstraction wallet mode that uses smart contract accounts to remove private key exposure entirely. The 2024 annual report documents 500,000+ phishing sites blocked, 300,000 high-risk addresses flagged, and 80 million token security checks performed. The company holds a FinCEN MSB license obtained in February 2024 and operates an Asia-Pacific hub at Hong Kong Cyberport.

Coin98 Super Wallet is a non-custodial multi-chain wallet available as a mobile app and Chrome browser extension, supporting storage, sending, and receiving of assets across more than 140 blockchains including Solana, Ethereum, BNB Chain, and Polygon. The wallet supports both EVM and non-EVM networks natively, with full NFT support across all chains. Key management options include standard seed phrases, social login through Google, Facebook, and Apple ID, and integration with Ledger and Trezor hardware wallets. An AI assistant named Cypheus is embedded for guidance and product support, while the Zen Card feature combines hot and cold wallet properties in a single hybrid instrument. The platform has grown to serve more than 10 million users across 170 countries since its founding in Vietnam in 2018. Coin98 Messenger provides a blockchain-based messaging layer supporting peer-to-peer payments accessible via wallet address through the OneID identity system. The DApp browser inside the wallet connects users to more than 15,000 dApps, with 120 new dApps onboarded through 2025 alone. The C98 token enables staking for passive yields and X-Points that translate into governance weight and improved tier access for early project launches on the platform.

TrustKeys Network's messaging layer is built on a Decentralized Account Model (DAM), storing user identity and session keys on-chain rather than on central servers. Messages are encrypted using military-grade cryptographic protocols, and neither TrustKeys nor any intermediary can access message content. Voice and video OTT calls operate under the same encryption stack, accessible via the web interface at app.dem.chat. The privacy architecture extends to enterprise and government use cases, where TrustKeys offers its DAM infrastructure with administrative controls and organization-wide encryption. The non-custodial wallet applies the same principle: users hold their own 24-character private keys with no server-side key escrow. Smart contract security has been audited by Verichains, covering the encryption architecture throughout message transit and storage. Founded in 2021 with $3.6 million in backing, TrustKeys markets its privacy stack to both individual crypto users and institutional customers.

3NS builds decentralized identity into every .Web3 domain through a DID (decentralized identifier) record anchored to each registration. The Agent Domain Protocol specifies that each domain carries its own DID alongside registry and resolver contract addresses per supported chain, making identity portable and verifiable across blockchains including Solana, Ethereum, and Polygon. This design enables autonomous agents to authenticate with one another without relying on a centralized directory. Domains accumulate reputation scores and verifiable credentials based on performance metrics, providing trust signals for agent-to-agent interactions. On-chain governance contracts with versioning and rollback capabilities allow domain owners and collective token holders to manage and update identity configuration transparently. The MIT-licensed Agent Domain Protocol specification defines how these identities are structured, published, and discovered across participating networks.

ChangeNOW's standard crypto-to-crypto exchange service requires no account creation, email address, or identity verification. Transactions are tracked by wallet address and a generated exchange ID rather than user profiles, allowing anyone to swap among more than 1,500 cryptocurrencies across 110+ blockchains without submitting personal information. This no-KYC design positions ChangeNOW as an accessible option for users who prioritize financial privacy in their on-chain activity. Beyond the baseline no-registration model, ChangeNOW has added explicit privacy features including private on-chain transfers, described as a privacy-routing mechanism for transaction obfuscation. The platform's automated AML screening operates on the back end, triggering identity verification only for transactions flagged as high-risk, with refunds available to users who decline. For Solana users, this means SOL and SPL token swaps from any supported chain can be completed without disclosing personal data to the exchange layer itself.

Bitbns is registered with India's Financial Intelligence Unit (FIU-India) and operates in compliance with FATF standards for Virtual Asset Service Providers (VASPs), placing it within the formal regulatory framework governing crypto platforms in India. The exchange enforces mandatory KYC verification for all users, a requirement aligned with anti-money laundering obligations under Indian financial regulations. Identity verification on Bitbns extends beyond documentation checks: the platform requires two-factor authentication and supports biometric login through its mobile application. These layered controls reflect the compliance posture the exchange adopted in response to India's evolving and at times restrictive regulatory environment for digital asset service providers.

Mercuryo embeds identity verification and compliance screening directly into its payment widget, giving partner applications KYC and AML capabilities without requiring them to build or license those systems independently. As of mid-2026, the platform has verified more than 12 million users, and the company reports that new users can complete identity verification and their first transaction in under 15 seconds. The company holds financial licenses across multiple jurisdictions and achieved ISO 27001 certification for information security management in April 2026 — a credential it markets specifically as a compliance benefit for enterprise partners with their own regulatory obligations. By handling KYC, AML screening, and regulatory compliance at the infrastructure level, Mercuryo removes one of the primary barriers to embedding crypto capabilities into consumer-facing wallets, exchanges, and decentralized applications.

StealthEX is a non-custodial instant swap service that treats privacy as a baseline requirement rather than an optional feature. No account registration, email address, or personal details are needed to complete a swap — users provide only a destination wallet address, and most transactions settle without any identity verification. KYC is triggered only for large-volume swaps or transactions flagged by the platform's AML screening layer. Funds never pass through StealthEX custody; they move from the user's wallet to the destination wallet directly, with StealthEX acting only as the exchange coordination layer. The service supports over 2,000 cryptocurrencies, including privacy coins such as Monero and Zcash, which are frequently cited by users as a core use case. Solana and Solana-native tokens are fully supported, allowing SOL to be swapped across hundreds of pairs without manual bridging or account setup. Hardware wallet-initiated swaps are also supported, letting users maintain cold-storage custody throughout the exchange and keeping private keys off any internet-connected device.

Netki provides identity verification infrastructure designed from the ground up for blockchain and digital asset applications, founded in 2014 by early internet pioneers well before regulatory scrutiny of the industry intensified. Its three products cover distinct points in the identity lifecycle: OnboardID for user onboarding via document validation and biometric verification, TransactID for encrypted identity data exchange between counterparties in regulated transactions, and DeFi Sentinel as an on-chain identity oracle for real-time screening before blockchain finalization. A distinctive aspect of Netki's identity approach is the breadth of its document support — covering four times more ID types than typical providers — and its stated commitment to above-average facial recognition accuracy across racial diversity, which the company publishes as a product specification. The identity layer underlying all three products is designed to operate across public and private blockchains, with ecosystem deployments on Sui and Polymesh enabling developers to embed compliant identity verification directly into decentralized applications and institutional blockchain protocols.

Sardine is an enterprise KYC/AML platform founded in 2020 by former Coinbase and Revolut risk executives who built its identity layer on behavioral biometrics and device intelligence profiling 6.6 billion devices globally. The onboarding suite covers KYC and KYB verification, document authentication, bank account verification, and credit underwriting, with an AI KYC Agent auto-resolving onboarding edge cases at an 88% rate without manual review. On the AML side, Sardine provides transaction monitoring, customer risk scoring, sanctions screening, PEP screening, case management, and automated SAR generation within a single platform. As of mid-2026, it screens over $1.67 trillion in annual transaction volume for 450-plus enterprises across 70 countries, including Nubank, Gusto, Deel, and FIS, covering Bank Secrecy Act, FinCEN, and international AML requirements.

OnMeta operates a built-in compliance stack covering KYC verification, AML screening, sanctions checking, and ongoing transaction monitoring, bundled with its on-ramp and off-ramp infrastructure. Merchants can use OnMeta's native KYC module or connect a third-party provider, with merchant onboarding via a Know Your Business process that typically completes within two to three working days. The platform was the first fiat on-ramp and off-ramp provider in India to register with the Financial Intelligence Unit under the Finance Ministry, following India's 2023 Prevention of Money Laundering Act amendments that brought virtual digital asset service providers under AML jurisdiction. For B2B clients, OnMeta's regulated status reduces their own compliance exposure when embedding a payment layer. Web3 projects in gaming, DeFi, and consumer applications can integrate OnMeta and inherit its compliance posture without maintaining a separate KYC or AML function.

KYC and regulatory compliance are core to Transak's infrastructure, handling identity verification through a Sumsub integration at the point of transaction within the partner's interface. A key differentiator, KYC Reliance, allows partners who have already verified their users to pass those credentials to Transak, letting verified users skip re-verification. Auth Reliance further removes friction, allowing returning users to transact using an existing session without a separate login. On the regulatory side, Transak holds money transmitter licenses in 11 US states, Digital Currency Exchange approval in Australia, and FCA Travel Rule compliance in the UK, with registered entities across the US, Canada, and Hong Kong. By embedding Transak, applications gain access to licensed, KYC-screened fiat rails without independently securing regulatory approvals across multiple jurisdictions.

TransFi builds KYC, KYB, AML transaction monitoring, and local regulatory compliance directly into its payments infrastructure, allowing enterprise partners to operate across more than 70 countries without constructing their own compliance programs. Clients integrating the Ramp or BizPay APIs inherit this compliance stack, reducing the cost of entering multiple emerging markets simultaneously. The platform integrates with Sumsub for identity verification workflows. JARVIS, TransFi's proprietary AI-driven compliance platform, consolidates sanctions screening, transaction monitoring, and identity verification into a single interface and automates decisions that would otherwise require manual review. The Ramp API enforces controls through signed URL authentication, role-based access, and webhook signature verification for partners integrating directly.

Trustee Global maintains a compliance stack spanning identity verification, transaction monitoring, and on-chain analytics across both applications. The platform uses KYCAID for identity verification, AMLBot and Crystal Intelligence for transaction monitoring, and Global Ledger for on-chain analytics. UAB Trustee Global is incorporated in Lithuania and licensed as a virtual asset service provider, providing the legal basis for its EU operations. In September 2025, Ukraine's National Bank concluded a 17-month inspection of Trustee Plus and issued a negative decision on two of seven alleged violations tied to fiat operations run by a Polish partner; the Lithuanian VASP entity faced no regulatory objections. New user registrations from Ukraine were suspended from May 2024 during the inspection period. EU services continued uninterrupted through the Lithuanian entity, and the company's about page links public penetration test reports for both iOS and Android builds of Trustee Plus.

BoomFi integrates real-time AML screening through a partnership with TRM Labs, a specialist blockchain intelligence firm, covering all transactions processed through its payment infrastructure. As a licensed Virtual Asset Service Provider (VASP) in Poland, BoomFi operates within the European regulatory perimeter and is positioned for alignment with the EU's MiCA framework, while its Canadian entity Plexa Finance Ltd is registered with FINTRAC as a Money Services Business authorised for virtual currency exchange. The platform's compliance infrastructure is designed to serve merchants across multiple regulatory regimes simultaneously, with multi-jurisdictional licensing covering Europe, North America, and the UAE. Its Crypto On/Off Ramp product is specifically backed by a European VASP licence with Virtual IBAN capability, enabling compliant fiat-to-crypto and crypto-to-fiat flows for embedded fintech and brokerage platforms.

ZKP2P minimizes personal data disclosure during fiat-to-crypto conversion by design. The attestation layer — whether ZK proofs in V1 or TEE-based verification in the current V3 — reveals only the payment amount, recipient identifier, timestamp, and transaction ID to the smart contract, without exposing full payment account details or email contents on-chain. No KYC is required for initial transactions on the Peer consumer application. Because buyers pay sellers directly through their existing payment apps, no central service accumulates records linking user identities to crypto addresses. Settlement is enforced by smart contracts validating the cryptographic attestation autonomously, removing the human review process that typically requires collecting identity documentation. Privacy is structural rather than a policy choice, built into the protocol non-custodial architecture.

CoinsPaid embeds automated KYC/AML compliance directly into its enterprise crypto payment gateway, integrating Chainalysis and Crystal Blockchain for real-time transaction screening. This compliance stack is a primary selling point for iGaming operators — the platform's largest market at over 70% of revenue — who face regulatory requirements when accepting crypto at scale. Named clients include 7Bit Casino, King Billy, PlayAmo, and Vavada, all operating in regulated gambling jurisdictions. The platform's CCSS Level 3 certification, audited by Hacken in 2026, covered access management, transaction authorization, logging, monitoring, and risk management procedures. CoinsPaid also holds ISO 27001 certification from Bureau Veritas and has a MiCA CASP application under review at Estonia's Finantsinspektsioon following the July 2026 expiry of its VASP licence. Merchants evaluating the platform for regulated markets should verify current licensing status before onboarding.

CPAY includes a built-in KYC and AML compliance layer that delivers automated identity verification, transaction monitoring, and sanctions screening without requiring a separate third-party integration. Designed for high-risk verticals such as iGaming, forex, and contracts-for-difference brokerage, the layer addresses intense regulatory scrutiny on incoming crypto flows. Being embedded in the same modular stack as the payment gateway means operators deploy compliance controls as a unified solution rather than assembling disparate services. The compliance module is one of five product layers that can be adopted individually or combined into a full-stack deployment with the payment gateway, Wallet-as-a-Service, Agentic Payments, and white-label tools. MPC-based key management, encrypted key storage, and mandatory multi-factor authentication supplement the overall compliance posture. Solana-based applications targeting regulated markets can use CPAY integrated KYC/AML tooling without sourcing identity verification from a separate provider.

Interlace embeds compliance directly into its card issuance infrastructure rather than treating it as an external service. The platform runs on-chain KYT screening on every crypto deposit for AML compliance, and client KYC and KYB are handled within the API integration layer instead of being delegated to partner businesses. This built-in approach reduces the regulatory burden on customers building card programs. The regulatory stack spans FinCEN MSB registration in the United States, an FINTRAC MSB in Canada, a Trust or Company Service Provider license in Hong Kong, and a payments license in Lithuania. The platform also holds PCI-DSS Level 1 certification, the highest tier of international card payment security. These credentials let Interlace issue cards across regions under a single API contract while managing compliance centrally.
