Babylon said its Trustless Bitcoin Vaults, or TBV, protocol has completed a security audit by Runtime Verification as it prepares native Bitcoin for collateralized lending on the Aave v4 mainnet. The audit, according to Runtime Verification, lasted seven weeks and was completed in May 2026. The review combined design analysis, manual code review, and formal verification based on Kontrol, the firm’s symbolic execution engine. Runtime Verification said the work covered the full vault lifecycle, atomic cross-chain mint and redemption flows, and the settlement, borrowing, and liquidation logic tied to the Aave v4 integration. It also said every issue identified during the audit was either resolved during the remediation period or otherwise confirmed. The disclosure came from a post by Babylon on X, where the project framed the completed review as a step toward bringing native Bitcoin-backed lending to Aave v4.
