Escrow & Settlement Custody
Frequently Asked Questions
Common questions from CTOs and founders about implementing secure, compliant custody for OTC trades.
We deploy a custom, audited smart contract as a neutral third-party escrow. The contract holds the digital assets (e.g., USDC, ETH) from the buyer until pre-defined settlement conditions are met. Both parties must cryptographically sign the release. This eliminates counterparty risk, ensures atomic settlement, and provides a transparent, immutable audit trail for the entire transaction.
