[Zest Releases Bitcoin Collateral Vault Mainnet Demo On-Chain Proof] BlockBeats news, on September 23, Bitcoin lending protocol Zest Protocol released the 'Proof of Mainnet Deployment,' demonstrating that the Bitcoin Collateral Vaults mainnet can now be independently verified. A total of 3 Bitcoin transactions and 7 Ethereum transactions have been publicly disclosed. The product design locks BTC in Bitcoin mainnet vaults without wrapping or cross-chain bridges, while enabling stablecoin lending on Ethereum and other EVM chains. This functionality remains a mainnet prototype and is not fully open for deposits and lending. The official roadmap is divided into two phases: Phase 1 restricts BTC settlement paths using pre-signed transactions, and Phase 2 transitions to BitVM verification. A functional mainnet prototype is already operational, and the team is accelerating formal deployment.
