MetaKeep

MetaKeep is a San Francisco-based enterprise Web3 infrastructure company founded in 2022. Its core product is an invisible wallet API that assigns hardware-secured, non-custodial cryptocurrency wallets to users using nothing more than an email address or phone number as an identifier. The result is a wallet onboarding experience with no seed phrases, no browser extension popups, and no new account creation — users simply authenticate via their existing email and receive a wallet that follows them across every application built on the MetaKeep platform.

The Invisible Wallet Model

Traditional Web3 onboarding requires users to generate a seed phrase, install a browser extension such as MetaMask, and manually approve every transaction. This friction is widely cited as the primary barrier to mainstream adoption. MetaKeep eliminates each step. When a developer calls the getWallet API with a user identifier, MetaKeep deterministically derives and returns a wallet address backed by its hardware security infrastructure. No user action is required to receive a wallet, and the same identifier always resolves to the same address on mainnet — enabling consistent identity across applications without any on-device key storage.

Transaction signing follows a lightweight challenge-response flow. Rather than approving transactions inside a browser wallet, users receive an out-of-band prompt — typically an email code — that authorizes the hardware module to sign on their behalf. The friction is comparable to a standard two-factor authentication check, far below the approval friction of conventional Web3 wallets.

Security Architecture

MetaKeep's security model is built on Hardware Security Modules (HSMs) certified to FIPS 140-2 Level 3, the same standard used in high-security financial infrastructure. Private keys never leave the hardware perimeter. The platform's Generation 3 Wallet Infrastructure applies zero-trust principles throughout: full memory encryption and isolation at rest and during compute make it physically impossible for MetaKeep employees or developers to acquire a user's private key, even in the event of an infrastructure breach. Keys are burned to individual users and cannot be exported or reassigned.

This approach contrasts with custodial alternatives, where a centralized operator holds private keys on behalf of users, and with self-hosted software wallets, where keys are vulnerable to device compromise. MetaKeep's model combines the convenience of custodial UX with the security guarantees of a hardware wallet and the ownership model of self-custody. The company has filed patents with both the USPTO and WIPO covering aspects of its wallet protocol.

Blockchain Support and Developer Integration

MetaKeep supports Ethereum and all EVM-compatible chains, Solana, and EOS-based chains including FIO. Additional chains are added based on developer demand. The platform's SDK is designed for rapid integration — five minutes to basic wallet generation in production, fifteen minutes to a functioning decentralized application — and surfaces features including gas abstraction through its Lambda Engine, smart contract deployment, and cross-chain transaction management.

Developers call getWallet dynamically rather than caching results. This design decision intentionally transfers custody of the wallet-to-identity mapping to MetaKeep's tamper-resistant infrastructure, removing the need for developers to secure cached associations against modification attacks on their own systems.

Solana Ecosystem Presence

MetaKeep has a meaningful footprint within the Solana ecosystem. The company serves as the non-custodial wallet infrastructure layer for GameShift, Solana Labs' Web3 developer toolkit targeting game studios. Within GameShift, MetaKeep provisions individual Solana wallets for each game user, with private keys stored inside HSMs that are specifically engineered to never export key material. This architecture allows game developers to offer players true asset ownership without requiring them to understand private keys or manage seed phrases.

The GameShift integration also powers transaction authorization via email-based challenge-response, consistent with MetaKeep's broader UX philosophy. Solana Labs is listed among MetaKeep's named enterprise clients alongside Coinflow, Civic, and MakersPlace.

Enterprise Clients and Partnerships

Beyond Solana Labs, MetaKeep's infrastructure is used across fintech, gaming, real-world assets, marketplace, and identity verticals. The platform reports over $250 million in assets under administration and has maintained operational reliability continuously since its 2022 launch.

Key partnership announcements include a collaboration with SKALE Network for Web3 key management and a deal with MetaWorks to power a Web3 tap-to-pay digital wallet product. These integrations reflect MetaKeep's positioning as a backend infrastructure layer rather than a consumer-facing product — its value is delivered through the applications developers build on top of it.

The company has also expanded its infrastructure to support AI agents and automated bots, allowing non-human principals to hold and transact with on-chain assets using the same hardware-secured wallet model as human users. This positions MetaKeep ahead of the growing demand for autonomous on-chain agents.

Team and Company Background

MetaKeep was built by engineers with backgrounds at Diem (Facebook's blockchain project), WhatsApp Pay, Google, Microsoft, and X (formerly Twitter). The company operates as Passbird Research, Inc. and is affiliated with Rezolve AI. The founding team's experience in high-scale payment systems and consumer identity products is reflected in MetaKeep's focus on production reliability and enterprise-grade security from day one.

The platform claims 500x higher user conversion compared to traditional wallet onboarding flows — a figure that reflects the elimination of seed phrase generation and extension installation as prerequisites for Web3 participation.

Market Position

MetaKeep competes in the embedded wallet space alongside products such as Privy, Dynamic, Magic, and Turnkey. Its primary differentiator is the depth of its hardware security guarantee: while most embedded wallet solutions rely on software-based key management or cloud KMS services, MetaKeep roots its security in physical HSM hardware certified to FIPS 140-2 Level 3. This distinction is significant for enterprise buyers in regulated industries where key management standards are contractual or regulatory requirements.

MetaKeep's model also avoids the "social recovery" framing common to many wallet-as-a-service products. Users do not configure guardians or delegate recovery to third parties; instead, MetaKeep's hardware infrastructure functions as the permanent, tamper-resistant custodian of key material while keeping the user as the cryptographic owner.

With Solana adoption driven through the GameShift partnership and continued multi-chain expansion, MetaKeep represents one of the more technically mature wallet infrastructure providers operating across the Solana ecosystem.
