Aave Bitcoin Plan Advances Amid Governance Scrutiny

Babylon Labs Proposes Native Bitcoin Collateral for Aave V4

Babylon Labs has put forward a proposal to integrate native Bitcoin as collateral on Aave V4, a move that would bypass the need for wrapped Bitcoin or a centralized custodian. The plan, however, is still subject to community review, risk analysis, and governance votes.

Under the proposed system, Bitcoin could be used as collateral for Aave loans without requiring users to first transfer their BTC to a custodian or convert it into a freely traded wrapped token. Babylon Labs presented this concept to Aave’s governance forum on October 14, building on discussions that began with an earlier “temperature check.”

The design leverages “Trustless Bitcoin Vaults.” Users would lock their BTC into a Taproot-based arrangement on the Bitcoin network. Aave V4 would then record restricted collateral units within a dedicated lending market. These accounting units are not designed to circulate as standard wrapped Bitcoin.

The appeal of this approach lies in allowing Bitcoin holders to borrow stablecoins against their BTC while the underlying Bitcoin remains subject to Bitcoin-side spending conditions. Aave’s proposed “hub-and-spoke” design aims to isolate the specific risks associated with this new market, rather than commingling them with other collateral assets.

However, the integration is far from finalized. The current Aave Request for Comment represents a governance stage, not a live borrowing product. Several steps remain, including the establishment of risk parameters, securing community support, a Snapshot vote, and ultimately, an on-chain proposal.

Forum participants have already raised technical questions concerning emergency pause mechanisms and the control of vault infrastructure components. These details are crucial in lending protocols, where the ability to release or liquidate collateral can be critical during periods of market stress.

For now, the proposal signifies a significant effort to bridge Bitcoin liquidity with Ethereum-style lending, with the most challenging operational questions currently being addressed in public.
