Babylon has submitted a governance proposal to bring native Bitcoin collateral to Aave V4, targeting a mechanism that would let Bitcoin holders borrow stablecoins without relinquishing their BTC exposure. The proposal is in its early stages and has not been approved or implemented; all features and terms remain subject to Aave governance decisions.
What the Proposal Covers
The core idea is straightforward: Bitcoin holders would use native BTC as collateral to access stablecoin liquidity through Aave V4’s lending infrastructure. Rather than selling Bitcoin to raise capital, a borrower would secure their BTC position and draw a stablecoin loan against it, preserving long-term exposure to the asset while meeting near-term liquidity needs.

The proposal distinguishes native Bitcoin from wrapped representations such as WBTC. Wrapped tokens introduce an additional trust assumption, namely a custodian or bridge that mints the derivative. A native BTC collateral model, if technically realised, would reduce that counterparty layer, though the precise custody and cross-chain architecture would still require governance-approved implementation details.

Babylon has previously worked on non-custodial Bitcoin staking frameworks, and this proposal extends that direction toward DeFi lending markets alongside other non-custodial Bitcoin initiatives. Aave V4, the lending protocol named in the proposal, is a decentralised liquidity market on Ethereum that uses overcollateralised loan mechanics.

Potential Benefits and the Risks That Remain
For long-term Bitcoin holders, the primary appeal is capital efficiency: BTC held as collateral can generate stablecoin liquidity for operational or investment purposes without triggering a taxable disposal event or sacrificing Bitcoin exposure. This is the stated use case in the proposal.
The risks are structural and significant. Bitcoin’s price volatility means collateral values can fall sharply and trigger liquidations if a position drops below its required collateralisation ratio. Any cross-chain mechanism linking Bitcoin’s UTXO-based ledger to an Ethereum lending contract also introduces bridge or custody risk, the specific form of which has not been disclosed in the proposal.
Governance approval, security audits, oracle design for BTC price feeds, and the selection of supported stablecoins all remain open questions. The proposal is subject to community deliberation before any of these parameters are set. Aave governance has previously taken weeks to months to evaluate and ratify major protocol additions.
What to Watch Next
The path from proposal to live product runs through Aave’s formal governance process: a temperature check, a snapshot vote, and an on-chain governance execution. Each stage can surface new objections or require revised parameters. Observers tracking Bitcoin’s expanding footprint across DeFi protocols will want to monitor the Aave governance forum for community feedback and any updated specification from Babylon.
If the proposal advances, the key implementation milestone will be the technical design for securing native BTC on Bitcoin’s base layer while making it legible as collateral to an Ethereum smart contract. That architecture, more than the proposal itself, will determine whether the product delivers on its stated risk profile.
