Zest Protocol enables Bitcoin-native lending, BTC yield and collateralized borrowing through Stacks and future Bitcoin L1 vaults.

Zest Protocol（ZEST） is a Bitcoin-focused DeFi lending protocol built around the Stacks ecosystem and expanding toward direct Bitcoin L1 collateralization. Its current Stacks Market lets users deposit assets such as sBTC, STX, stSTX and stablecoins to earn yield or borrow against collateral, while the upcoming Bitcoin Collateral Vaults are designed to let users borrow stablecoins from EVM-chain liquidity while keeping BTC on Bitcoin L1, using BitVM-based rules rather than custodians, wrappers or federated bridges.
