 Bitcoin holders could soon borrow stablecoins through Aave without transferring their BTC away from the Bitcoin blockchain, under a new proposal from Babylon Labs that would expand one of decentralized finance's largest lending platforms.
 In an <a href="https://governance.aave.com/t/arfc-onboard-native-btc-as-collateral-to-aave-v4-via-babylon-trustless-bitcoin-vaults/25845" rel="noopener noreferrer nofollow">October 14 governance proposal</a>, Babylon outlined an integration allowing users to lock native Bitcoin in special Taproot vaults while borrowing stablecoins through Aave V4.
 Unlike conventional Bitcoin-backed DeFi lending, which often relies on wrapped BTC representations, the underlying collateral would remain on Bitcoin. The proposal has advanced beyond an initial community temperature check but still requires further risk assessment and governance approval.How Aave Could Accept Bitcoin Without Bridging BTC 
 The proposed system uses Babylon's Trustless Bitcoin Vaults, or TBVs, to connect Bitcoin collateral with Aave's Ethereum-based lending infrastructure.
 A user would lock BTC in a Taproot transaction output on the Bitcoin network. A corresponding record would then represent that collateral within Aave V4, allowing the borrower to access stablecoin liquidity without transferring the underlying coins to Ethereum.
 The design introduces two components: the Babylon Spoke, which manages BTC-backed borrowing, and the BTC Vault Swap Spoke, which supports liquidation and settlement.
 Because Aave V4 normally accepts ERC-20 collateral, the integration still creates a restricted accounting token representing the Bitcoin vault. However, that token cannot be freely traded or transferred like conventional wrapped BTC.
 The proposal builds on Babylon's earlier <a href="https://coinpaper.com/6244/babylon-labs-and-lombard-protocol-bring-liquid-bitcoin-staking-to-sui" rel="noopener noreferrer nofollow">Bitcoin staking</a> initiatives, which sought to expand BTC's utility beyond holding and transferring value.
 Babylon says its existing staking infrastructure has activated more than 100,000 BTC cumulatively since August 2024, providing evidence of demand for Bitcoin-based financial applications.Governance Questions Emerge Over Bitcoin Collateral 
 Although the proposed system avoids transferring native BTC into a custodial bridge, its withdrawal mechanics introduce additional considerations.
 On October 16, a governance participant questioned whether Babylon-controlled emergency mechanisms could prevent users from withdrawing collateral, even when the Bitcoin remained protected inside its vault.
 Babylon engineer Aleksa Opacic responded that emergency pauses cannot move or release BTC but can temporarily block withdrawals, repayments and liquidations.
 According to Babylon, emergency controls would involve a four-of-seven interim governance multisignature arrangement and a separate three-of-five emergency guardian group. Contract upgrades would require a five-day timelock, while emergency pauses could happen immediately.
 These distinctions matter because collateral security does not automatically guarantee uninterrupted access, particularly when borrowers must maintain adequate collateralization during volatile markets.

 The integration also proposes a revenue-sharing agreement between Aave DAO and Babylon Foundation.
 Under the preliminary structure, Aave would receive the first $500,000 of qualifying annual revenue. Above that threshold, additional revenue would be divided between Aave, Babylon and token-purchase allocations according to several tiers.
 At higher revenue levels, part of those allocations would fund market purchases of AAVE and BABY, although the proposal does not guarantee borrowing demand or token purchases.
