Custody Companies

Zenrock is a decentralized custody platform that operates a proprietary blockchain called zrChain. The system enables users to mint wrapped versions of non-native assets on Solana, including zenBTC (wrapped Bitcoin) and zenZEC (wrapped Zcash). The architecture uses distributed MPC (dMPC) for key management, with onchain verifiable settlement. A bridge protocol called ZenTP connects zrChain to Solana and facilitates asset transfers. The platform includes a privacy product called Hush and supports yield generation on zenBTC through integrations with DeFi protocols including Orca, Raydium, Jupiter, Meteora, and marginfi. The system is designed to serve both retail and institutional users requiring cross-chain asset custody with distributed key control rather than centralized key management.

Bosonic is an institutional digital asset infrastructure platform that provides cross-custodian net settlement, liquidity aggregation, repo and borrow-lend services, and tokenized securities trading. The platform uses atomic settlement mechanics to eliminate counterparty and settlement risk by enabling trades to clear across multiple custodians without requiring pre-funding. Bosonic Securities operates a FINRA and SEC-registered Alternative Trading System for digital asset securities. The platform serves institutional trading desks and market makers.
