Zest Protocol has launched a mainnet demo of its Bitcoin Collateral Vaults. The demo allows native Bitcoin holders to deposit their BTC in a self-custodial Taproot vault on Bitcoin and borrow USDC on Ethereum. The Bitcoin remains on its home chain, unwrapped and unbridged to Ethereum, throughout the loan lifecycle. During this test phase, each wallet is capped at 0.001 BTC of collateral to enable controlled testing conditions before a broader launch. The architecture leverages BitVM verification to prove Ethereum lending events directly on Bitcoin.
