A native BTC collateral path: the first thing to be verified may not be the endpoint, but whether participants can enter the test and provide feedback. Trustless Bitcoin Vaults (TBV) public testnet is providing such an opportunity: users can test the process and submit product feedback.

Of particular interest is how it handles collateral. Native Bitcoin can be used as collateral without wrapping, cross-chain bridging, or centralized intermediaries of trust. The recommended project materials describe the design as self-custody—your keys, your Bitcoin. The first use case is borrowing on the public testnet by combining native Bitcoin support with Aave v4: users can submit native BTC as collateral and borrow supported Ethereum assets such as USDC or USDT.
