BitGo provides institutional wallet infrastructure for Solana, from API-created multi-sig and MPC hot wallets to cold storage under OCC-regulated qualified custody. Its wallets hold SOL and SPL tokens, and a WalletConnect integration lets BitGo self-custody hot wallets connect directly to Solana dapps under the same policy controls as the rest of the account. Platforms that want to embed wallets can use BitGo's white-label Crypto-as-a-Service API, which serves fintechs, neobanks and payment apps. It suits organisations that need audited, insured custody, backed by SOC-1 and SOC-2 Type 2 certifications and $250 million of insurance cover. BitGo is not a consumer wallet app: access runs through its API and operations platform.

Para stands out as a leading identity wallet management solution on Solana, offering institutional-grade security through sophisticated multi-party computation (MPC) infrastructure. The platform's Para Modal product enables seamless authentication and wallet management across applications while maintaining robust security through features like hardware secure enclaves and distributed key management.Para's approach to identity management combines familiar Web2 authentication flows with Web3 security, allowing users to access their wallets through social logins and biometric authentication. The platform's innovative 2-of-2 MPC system, comprising a User Share, Cloud Share, and Passkey, ensures that private keys are never fully assembled in one location while maintaining quick access for legitimate transactions. This makes Para particularly valuable for applications requiring secure, user-friendly identity management solutions.

Crypto.com DeFi Wallet is a non-custodial multi-chain wallet supporting more than 4,000 tokens across more than 30 blockchains, including Solana. Unlike the platform custodial exchange products, the DeFi Wallet gives users full control over their private keys and assets. SOL holders can access native on-chain staking directly through the wallet Earn tab with a minimum of just 0.01 SOL, and a built-in dApp browser enables connection to Solana decentralized applications without leaving the wallet interface. The wallet combines asset management, staking, swaps, transfers, and NFT management in a single self-custody interface, a comprehensive solution for users seeking on-chain Solana exposure. A 5% commission applies to staking rewards, with standard Solana network fees for transactions. As part of a platform holding SOC 2 Type II, ISO 27001, and PCI DSS 4.0 certifications and serving more than 150 million users, the DeFi Wallet provides a regulated-adjacent yet non-custodial entry point for users who want self-custody without abandoning a familiar consumer brand.

Mixin Messenger is the primary user-facing application, available on iOS and Android, combining an encrypted messaging interface with a self-custodial multi-chain wallet. Authentication relies on a phone number and six-digit PIN rather than a written seed phrase, while the TIP (Throttled Identity Protocol) manages key derivation with key fragments distributed across a Password Network and Signer Network. The private key resides in the device's local secure enclave, and users can export a full mnemonic phrase and private key at any time, preserving self-custody even if the platform becomes unavailable. The wallet supports thousands of tokens across 32+ integrated blockchains, including Solana's SOL and SPL tokens. Mixin Safe extends the wallet offering to individuals, families, and businesses managing significant holdings, particularly Bitcoin. It implements a 2-of-3 multisignature scheme combining an Owner Key held on a hardware wallet, Members Keys designated to co-signers such as family members or business counterparties, and a Recovery Key governed by a Bitcoin Script timelock. MPC through Threshold Signature Scheme technology distributes the Members Keys across more than 100 Mixin Network validator nodes for added resilience against infrastructure compromise. Together, Mixin Messenger and Mixin Safe form a custody stack serving casual wallet users through institutional-grade cold storage needs.

DefiApp is built around a self-custody smart wallet architecture powered by ERC-4337 account abstraction. At signup, the platform automatically generates a single EVM-compatible smart account that works across Ethereum, Arbitrum, Base, and BNB Chain, along with a separate Solana wallet — all accessible from one interface without the user managing seed phrases for each network individually. Social login options simplify onboarding further, allowing new users to access the wallet via familiar authentication methods while retaining non-custodial control of their private keys. The result is a wallet experience that approaches the ease of a centralized exchange account while preserving the core DeFi principle of user-controlled funds. Gas sponsorship is the standout wallet-level capability: DefiApp covers transaction fees on all supported chains at the application layer, meaning users can interact with DeFi protocols across five blockchains without ever holding a native gas token. This is made possible through the HOME token, which functions as the gas abstraction mechanism — the protocol settles underlying fees on the user's behalf. Fiat on-ramps and off-ramps are integrated directly into the wallet, connecting bank accounts to on-chain positions without a separate centralized exchange. The smart account design also enables features like fee discounts through HOME staking and transaction batching, capabilities unavailable in standard EOA wallets.

Loyal is a self-custody Solana wallet built around smart accounts — programmable constructs that enforce user-defined spending caps, token allowlists, and agent permissions at the blockchain level. When an AI agent is granted access, it operates strictly within the policy the user set and cannot exceed those limits under any circumstances. Unlike conventional wallets that require full private key exposure for agent delegation, Loyal makes the policy itself part of the on-chain execution path. The built-in assistant Milo automates stablecoin yield and routine tasks entirely within user-defined guardrails. The wallet is available as a browser extension, web application, and mobile app via the Solana Seeker dApp store. Handle-based payments through Telegram usernames allow peer-to-peer transactions without exposing wallet addresses. Users can self-host the frontend without data loss, reinforcing the non-custodial design. As of mid-2026, Loyal had 3,000 active on-chain policies and approximately $385,000 in active deposits across its smart account user base.
