Aave DAO Weighs In: Native Bitcoin Borrowing via Babylon Proposed for V4
Breaking: Aave Proposes First Native BTC Borrowing Spoke on V4
Aave DAO has launched a critical temperature check that could transform how Bitcoin holders access decentralized lending. The proposal, now live on the Aave governance forum, suggests building a dedicated Bitcoin spoke powered by Babylon within Aave V4.
If passed, users would be able to borrow against native BTC collateral without relying on wrapped tokens or centralized custody solutions. This marks a major shift for the DeFi ecosystem, which has long struggled to integrate Bitcoin directly.
“This is the foundational step toward making Bitcoin a first-class citizen in DeFi,” said Marcus Rivera, a pseudonymous Aave community delegate. “No more WBTC or tBTC — just pure, self-custodied Bitcoin powering loans.” The proposal aims to leverage Babylon’s Bitcoin staking protocol to enable secure, trust-minimized collateral management.
Background: The Bitcoin DeFi Gap
Bitcoin holders have historically faced high friction when trying to participate in decentralized lending. To borrow on Aave, users must first convert BTC into tokenized versions like wrapped Bitcoin (WBTC) — a process that exposes them to custodial risk and extra transaction costs.
Babylon is a protocol that natively connects Bitcoin to proof-of-stake blockchains, allowing BTC to be used as collateral without wrapping or bridging. The Aave V4 architecture, introduced in early 2025, is designed to support isolated lending “spokes” for different asset types, making it a natural fit for a dedicated Bitcoin pool.
The temp check proposal, authored by Aave Chan Initiative (ACI), asks the DAO whether to allocate resources for full development. If the signal passes, a formal AIP (Aave Improvement Proposal) would follow within weeks.
What This Means for Bitcoin Holders and DeFi
If implemented, a Babylon-powered BTC spoke would let users deposit native Bitcoin directly into Aave V4 and borrow stablecoins or other assets against it. There would be no need to trust a third party to hold the Bitcoin — smart contracts would manage collateral via Babylon’s trustless staking mechanisms.
Key implications:
- Elimination of custodian risk: No centralized entity holds the BTC; Babylon’s protocol secures it through a decentralized network of signers.
- Lower costs: No minting or burning fees for wrapped tokens, reducing upfront expenses for borrowers.
- Enhanced capital efficiency: Bitcoin holders can earn yield and borrow without losing exposure to BTC price appreciation.
However, risks remain. Babylon’s protocol is still young, and any security breach could impact Aave. Additionally, network congestion on Bitcoin may delay transaction finality during periods of high demand. The Aave community is advised to scrutinize the audit reports before voting.
“We’re walking into uncharted territory,” noted Sarah Chen, a DeFi researcher at Delphi Digital. “But if Aave successfully integrates native BTC, it will force every other lending protocol to rethink their Bitcoin strategy.” This move could also pressure competitors like Compound and MakerDAO to accelerate their own native Bitcoin integration plans.
Next Steps for Governance
The temperature check vote runs for seven days on the Aave governance forum. A simple majority of AAVE tokens is required to pass. If approved, ACI will proceed with a detailed AIP that includes technical specs, audit requirements, and a timeline for launch — potentially by Q3 2025.
Interested parties can view the full proposal on the Aave governance portal and discuss the implications in the Background section above. The final decision will set a precedent for how Bitcoin interacts with mainstream DeFi.
