Because individual Bitcoin transaction outputs cannot be divided, liquidations in Babylon's Aave V4 integration target one BTCVault at a time, allowing liquidators to make repeated calls until the borrower's position health is restored

To enable Aave V4 to track collateral on Ethereum, Babylon's integration creates a transfer-restricted ERC-20 token named vaultBTC as an internal accounting record representing locked Bitcoin on a one-to-one basis

To bypass multi-day Bitcoin redemption delays, permissionless liquidators using Babylon's BTC Vault Swap Spoke receive Wrapped Bitcoin (WBTC) immediately while authorized participants complete native Bitcoin settlement

Babylon's proposed integration introduces the Babylon Core Lending Spoke to Aave V4, where borrowers post vault-backed Bitcoin to draw supported assets like USDC, USDT, and WBTC
