The key to self-custody: is it only about keeping the private key in your hands? When BTC is used as collateral, whether the assets still participate in their native form is also worth关注. The recommended project materials for Trustless Bitcoin Vaults (TBV) will describe the design as “Self-custody: your keys, your Bitcoin.” Native Bitcoin can also be used as collateral—no wrapping, no cross-chain, and no centralized trusted intermediary.
There is already verifiable product action for this design: the first use case is on the public testnet, with native Bitcoin support integrated with Aave v4 for borrowing. Users can submit native BTC as collateral and borrow supported Ethereum assets such as USDC or USDT through Aave v4. The public testnet can be used to test the flow and provide product feedback: https://btc-vaults.testnet.babylonlabs.io/
