Institutional Digital Asset Custody

Ceffu provides enterprise-grade custody infrastructure for digital assets with institutional compliance, advanced security, and regulatory certifications. As the only institutional custody partner of the Binance Exchange, Ceffu delivers secure custody solutions built on multi-party computation (MPC) technology.

Core Custody Solutions

Qualified Wallet - Maximum Security Cold Storage: Institutional-grade cold storage built on MPC technology with distributed key management across geographically separated, air-gapped FIPS 140-3 compliant devices. Features 100% offline storage with threshold signing schemes (M-of-N key shares), segregated on-chain wallet addresses for complete transparency, customizable multi-approval policies with role-based access control, and guaranteed withdrawals within 4 hours. ISO 27001/27701 certified and SOC 2 Type 2 attested with automated AML review and real-time blockchain analytics.

Prime Wallet - Institutional Hot Wallet: High-speed institutional hot wallet combining transaction speed with institutional security. Features segregated on-chain deposit addresses for transparency, omnibus withdrawal architecture for instantaneous processing, periodic cold storage sweeps ensuring majority of holdings benefit from Qualified Wallet security levels, and MPC protection with role-based access controls. Exclusive integration with MirrorX off-exchange settlement platform enables instant delegation to Binance trading accounts.

Co-sign Wallet - Enhanced User Control: Institutional MPC wallet with 2-of-3 key share architecture providing enhanced transaction autonomy. One key share remains under direct institutional control on user's personal device (mobile, desktop, or HSM), enabling independent transaction approval without custody provider involvement. Maintains MPC security guarantees while accelerating signing for time-sensitive operations.

Security Architecture

Zero trust security model with separate authentication for every interaction, distributed key management eliminating single points of failure, MPC signing conducted entirely offline, and compliance with FIPS 140-3, ISO 27001/27701, and SOC 2 Type 2 standards. All solutions feature comprehensive disaster recovery plans with legal recourse unavailable in purely smart contract wallets.

Advanced Custody Applications

Collateralized Trading (MirrorRSV): Use cold storage assets as trading collateral without moving them from custody. Assets in segregated Qualified Wallets serve as collateral for representative tokens usable in Binance Portfolio Margin accounts. Supports both traditional digital assets and tokenized real-world assets (BUIDL, USYC, cUSDO) as collateral with full on-chain transparency.

Staking from Custody: Generate yield on assets held in cold storage through native proof-of-stake delegation and Ethereum liquid staking. Direct gateway access to validators on Solana, Injective, NEAR, and A Protocol networks. Ethereum liquid staking produces WBETH or stETH tokens while maintaining custody security.

Institutional Escrow: Third-party escrow for complex, high-value transactions including M&A, OTC trades, token sales, and dispute settlement. Built on Qualified Wallet infrastructure with segregated on-chain wallets, MPC multi-party approval requirements, and customizable release conditions.
