Babylon’s native Bitcoin collateral proposal for Aave v4

Babylon Labs has submitted an Aave governance “Temp Check” to enable native Bitcoin (BTC) collateral in Aave v4. The core upgrade is native Bitcoin collateral, allowing BTC holders to post BTC directly—without wrapped/tokenized versions like WBTC or renBTC. The plan uses Babylon’s trust-minimized Bitcoin vaults to lock BTC for Aave v4 while aiming to reduce reliance on third-party custodians and bridge operators. If approved, Aave v4 would add BTC collateral rails and expand BTC DeFi lending/borrowing with lower friction than tokenization. Key details for traders: Babylon’s Temp Check is at the community review stage, then moves to formal governance votes and technical verification. Multiple security audits are already underway (Coinspect, Sherlock, Zellic, ABDK, ZK Security), plus formal verification by Runtime Verification. The proposal also includes Aave-controlled risk parameters, oracle setup, and governance caps. Market relevance: while Babylon argues that over $1T in BTC is sitting idle in wallets, price impact is uncertain until governance and audits complete. Still, success could set a precedent for native BTC collateral across DeFi and increase competition for BTC liquidity as institutional interest grows. Bottom line: native Bitcoin collateral is the headline. For now, watch the Temp Check outcome and audit milestones—these are the catalysts that could shift sentiment around BTC-backed lending demand.
