Babylon's plan to let native Bitcoin serve as collateral in Aave V4 has moved into a further stage of the lending protocol's governance process, though additional votes and security reviews stand between the proposal and any launch.

Babylon's proposal to bring native Bitcoin collateral to Aave V4 has advanced to a new phase of the protocol's decision-making process, according to a Cointelegraph report dated Oct. 15, 2026. The proposal centers on allowing Bitcoin to be used directly as collateral inside Aave's next-generation V4 lending markets, rather than depending only on representations of BTC issued on other networks. Entering this stage generally signals that the idea has cleared an initial discussion or support-checking step and is moving toward a formal decision, but it is not an approval. The same report notes that further votes and security reviews remain before any launch could take place.
Aave decisions typically pass through several separate checkpoints: community discussion, an off-chain snapshot vote to gauge support, risk and technical evaluation, and finally an on-chain vote that executes the change if it passes. Movement into a new stage indicates the proposal has cleared at least one of these gates, not all of them. Because any step can end in rejection or in amendments that reshape the original idea, reaching a later phase does not guarantee adoption. Aave V4 is itself a new architecture, which means integration work and parameter-setting would likely continue in parallel with the governance timeline.
Bitcoin's base layer does not natively support the smart contracts that lending markets depend on, so BTC has historically entered on-chain credit markets through tokenized or wrapped versions issued by third parties. Those versions carry issuer, custody and bridge risks that native Bitcoin does not, which forms part of the argument for using the asset directly. Babylon's core work involves letting Bitcoin holders participate in proof-of-stake networks through cryptographic commitments rather than by moving coins off the Bitcoin blockchain. Extending that capability to collateral means a lending market would need ways to value, monitor and, where necessary, liquidate BTC positions under Bitcoin's own rules.
Proposals introducing a new collateral class typically raise operational questions: how the asset is priced, which oracle feeds are relied upon, what happens during a liquidation, and how the protocol behaves when liquidity thins or a network slows. Security reviews carry extra weight in this context, because a flaw tied to a new collateral type could affect participants across the wider market rather than a single isolated pool. The current stage therefore functions as a checkpoint rather than a green light, and the final outcome depends on subsequent votes together with audit and risk findings.
Babylon has put forward a proposal that would allow native Bitcoin to be used as collateral within Aave V4, the next version of the decentralized lending protocol. Rather than relying on wrapped or tokenized versions of BTC issued by third parties, the proposal would bring Bitcoin itself into the lending market's collateral framework. The idea has advanced to a new governance stage but has not been approved.
Aave's governance generally moves through discussion, an off-chain snapshot vote, risk and technical review, and finally an on-chain vote that executes a change. Reaching a new stage means the proposal has cleared at least one of those checkpoints and is closer to a formal decision. It does not mean the proposal is live, since later votes and security reviews can still alter or reject it.
Wrapped or tokenized Bitcoin is issued by third parties and therefore carries issuer, custody and bridge risks that native Bitcoin does not. Supporters of native collateral argue that using BTC directly removes some of those dependencies. The trade-off is technical complexity, because Bitcoin's base layer does not natively support smart contracts, so lending mechanics such as pricing and liquidation must be adapted.

Bitcoin's Still-Limited Role in DeFi Lending

Bitcoin remains the largest crypto asset by market capitalization, yet its presence in decentralized lending has been comparatively modest because the network was not designed for programmable finance. Most activity on Ethereum-based lending protocols involves ETH, stablecoins and liquid staking tokens rather than BTC. Proposals that would broaden Bitcoin's collateral role therefore matter for how far the DeFi lending sector's potential user and asset base could expand, while also adding new risk-management requirements. Babylon's effort sits within a wider push by several teams to connect Bitcoin to on-chain credit markets. Based on public news sources.
According to the proposal's current status, additional votes and security reviews are still required before any launch. Those steps typically include audit work and risk-parameter assessment for the new collateral type. Until those processes conclude and the remaining votes pass, native Bitcoin collateral is not available on Aave V4.
Not in the native form described by this proposal. Existing on-chain lending activity involving Bitcoin generally uses wrapped versions of the asset rather than BTC held on the Bitcoin network. The Babylon proposal is an attempt to change that, and it remains subject to the protocol's governance process.
