Babylon 提议在 Aave V4 上集成原生比特币抵押品，无需跨链桥和托管
ChainCatcher 消息，Babylon Labs 在 Aave 社区发起温度检查提案，提议通过 Babylon Trustless Bitcoin Vaults 协议在 Aave V4 上集成原生比特币作为抵押品。
该方案无需封装、跨链桥或托管方，用户将比特币锁定在 Taproot UTXO 中，赎回由链上规则（如贷款偿还）控制，直接结算至比特币 UTXO。提案部署两个 Aave V4 Spoke：Babylon Core Lending Spoke（借贷）和 BTC Vault Swap Spoke（清算后结算）。抵押品以 vaultBTC 形式存在，是一种转账受限的 ERC-20 代币，仅限在固定白名单地址间转移。清算流程中，清算人可立即以 WBTC 结算，后续由套利者完成比特币端赎回。
