Aave
Babylon Labs has published an ARFC on the Aave governance forum proposing to onboard native Bitcoin as collateral on Aave V4 through its Trustless Bitcoin Vaults (TBV) protocol. Aave announced the proposal on X and linked the forum thread, welcoming it as a way for users to lock native BTC on the Bitcoin chain and borrow supported assets against it — no bridges, wrappers, or custodians, with Bitcoin never leaving the Bitcoin network.

We built Aave Protocol, an open source and non-custodial liquidity protocol and the Aave app, a web interface for users to interact directly with the protocol.
