On Monday, Aave Labs announced via X that Babylon Labs submitted a Temp Check to Aave DAO to integrate Trustless Bitcoin Vaults (TBV) with Aave V4.
This would allow native BTC as collateral and introduce two new V4 Spokes, one for borrowing against BTC and one for post-liquidation settlement.
Trustless Bitcoin Vaults (TBV) allows anyone to use their native Bitcoin as collateral in supported on-chain applications, without transferring custody to any trusted third party.
TBV achieves this by locking BTC on Bitcoin inside a Taproot script. The conditions under which it can be moved are enforced cryptographically: redemption requires a valid zero-knowledge proof of an event on the host chain (e.g., Ethereum Mainnet), and any attempt to claim BTC without a valid proof can be challenged and stopped by an eligible challenger during a fraud-proof window. The depositor is always eligible to act as a challenger themselves, so they need not trust any third party to secure their BTC.
The protocol introduces no third-party custodian, signer consortium, or threshold-signature group with discretionary control over the underlying BTC. Spending conditions are encoded in the Taproot script and governed by zero-knowledge proof verification through a challenge-based procedure. Redemption is native to Bitcoin. The locked BTC moves to a recipient designated by the vault’s spending conditions, which reference events on the host chain.
Aave is a decentralized finance protocol that allows people to lend and borrow crypto. Lenders earn interest by depositing digital assets into specially created liquidity pools. Borrowers can then use their crypto as collateral to take out a flash loan using this liquidity.
Aave (which means “ghost” in Finnish) was originally known as ETHLend when it launched in November 2017, but the rebranding to Aave happened in September 2018. (This helps explain why this token’s ticker is so different from its name!)
AAVE provides holders with discounted fees on the platform, and it also serves as a governance token, giving owners a say in the future development of the protocol.
Aave protocol is a decentralized, open-source, and non-custodial money market protocol. Depositors earn interest by providing liquidity to lending pools, while borrowers can obtain overcollateralized loans by using the liquidity from these pools. AAVE is trading at $86.06 per token, down 0.21% in the last 24 hours.
The project allows people to borrow and lend in about 20 cryptocurrencies, meaning that users have a greater amount of choice. One of Aave’s flagship products is “flash loans,” which have been billed as the first uncollateralized loan option in the DeFi space. There’s a catch: they must be paid back within the same transaction.
