The borrowing market nonetheless wants closing approval earlier than holders can apply it to mainnet. Babylon reported 100% assist for the plan to attach its Trustless Bitcoin Vaults to Aave V4, and the subsequent step is an Aave Enchancment Proposal (AIP) for closing on-chain approval.
Discover the proposed market
BTC stays locked on Bitcoin; Aave acknowledges collateral on Ethereum and lends supported stablecoins.
The permissionless route makes use of WBTC now and native BTC redemption later. This stays a proposed design with liquidation danger.
Native BTC would again stablecoin loans, whereas WBTC nonetheless has a separate liquidation-settlement function.
Vote outcome attributed to Babylon. Late-2026 goal stays conditional. Credit score limits are proposed capability. Diagrams omit operator and governance element; liquidation danger and WBTC dependencies stay.
Below the proposed change, BTC would stay locked on Bitcoin, whereas an Ethereum-based accounting document would let Aave acknowledge it. Debtors wouldn’t want to produce a freely transferable wrapped Bitcoin token.
The governance proposal units out preliminary stablecoin credit score strains from Aave’s Core Hub liquidity pool of $8 million every for USDT and USDC, $1 million for GHO, and $2 million every for USDG and RLUSD.
A separate liquidity pool, the Babylon Hub, would let liquidity suppliers select publicity to native Bitcoin collateral, with its personal limits.
Danger adviser LlamaRisk recommends a 78% collateral issue for native BTC. The collateral document itself would stay non-borrowable, representing BTC securing a place.
Babylon targets mainnet for late 2026, topic to vary and affirmation.

Holding the underlying BTC on Bitcoin doesn’t take away liquidation or settlement danger. The Ethereum collateral document could be a transfer-restricted ERC-20 accounting unit, and a borrower might nonetheless lose vault collateral by way of liquidation.
Wrapped Bitcoin stays as a part of the construction
The design additionally retains a job for Wrapped Bitcoin (WBTC). Below the permissionless liquidation route, BTCVaultSwap would borrow WBTC from an Aave Hub to settle instantly with liquidators.

The proposed Core Hub draw cap for that settlement venue is 100 WBTC, separate from the stablecoin lending strains. Permissioned actors may liquidate and redeem vaults immediately with out drawing Hub liquidity, though charges or borrower compensation can nonetheless require WBTC.
Liquidation seizes complete vaults, even when clearing the debt requires lower than a vault’s full BTC worth, and the borrower receives discounted compensation for that the rest in wrapped BTC.
Potential debtors nonetheless want closing AIP approval and a confirmed rollout schedule earlier than this market strikes from governance backing to mainnet entry.
