Aave Proposal Moves To Add Circle Wrapped Bitcoin Collateral
TL;DR
- Aave Labs has proposed onboarding Circle Wrapped Bitcoin, or cirBTC, to Aave V3 Core and Aave V4 Core on Ethereum.
- The proposal says cirBTC is an ERC-20 token backed 1:1 by Bitcoin custodied at a regulated Circle entity.
- The move is still at the ARFC stage, meaning it needs community feedback, a Snapshot vote and a later AIP before any on-chain implementation.
- If approved, the listing would give Aave users another Bitcoin-backed collateral option as the market for BTC wrappers becomes more competitive.
Aave Labs has opened a governance proposal to add Circle Wrapped Bitcoin, known as cirBTC, as collateral across Aave V3 Core and Aave V4 Core on Ethereum, putting one of DeFi’s largest lending markets directly into the growing debate over institutional Bitcoin wrappers.
The proposal, posted to the Aave governance forum on June 10, asks the community to consider onboarding cirBTC after Circle launched the ERC-20 token on Ethereum mainnet on June 8. According to the proposal, cirBTC represents native Bitcoin and is backed 1:1 by BTC held with a regulated Circle entity, with reserves segregated from Circle’s corporate assets.
A New Bitcoin Wrapper Enters Aave Governance
The pitch is straightforward: if Aave approves the listing, users would gain a new Bitcoin-backed collateral asset inside the protocol’s core Ethereum deployments. That would put cirBTC into the same broader conversation as other wrapped Bitcoin products used across lending, liquidity and structured DeFi strategies.
Aave Labs said in the governance post that it has no financial relationship with Circle and is not being compensated for the proposal. That detail matters because collateral onboarding proposals can carry obvious commercial implications, especially when they involve assets backed by major centralized issuers.
The proposal is also not an immediate listing. It is currently at the ARFC stage, which is designed for community review and risk discussion. If the community broadly supports the move, the process would still need to proceed through a Snapshot vote and then a formal Aave Improvement Proposal before implementation.
Why cirBTC Matters For DeFi
Wrapped Bitcoin has long been one of the main bridges between Bitcoin liquidity and Ethereum-based DeFi. Traders and lenders use BTC wrappers to borrow stablecoins, earn yield, route collateral and build strategies without selling Bitcoin exposure.
Circle’s entry into this category adds a new institutional wrapper with a familiar issuer behind it. That does not automatically mean users will prefer cirBTC over existing alternatives, but it does create another option for protocols looking for regulated-custody-backed Bitcoin collateral.
For Aave, the question is less about branding and more about risk. Governance participants will likely want clarity around reserve transparency, redemption mechanics, liquidity, oracle support, counterparty risk and how quickly cirBTC can build reliable market depth.
Governance Still Has Work To Do
The proposal’s early stage means the market should not treat the listing as complete. Aave’s collateral decisions typically involve risk parameters, supply caps, liquidation thresholds and oracle configuration, all of which can shape whether an asset becomes widely used or remains a limited listing.
Still, the timing is notable. Circle launched cirBTC on Ethereum only days before the Aave proposal appeared, suggesting that major DeFi integrations could become an early battleground for the new asset.
If approved, cirBTC would give Aave another route for Bitcoin-backed borrowing and could add pressure to the wider wrapped Bitcoin market. For now, it is a governance proposal rather than a finished deployment, but it is one worth watching as institutional issuers move deeper into DeFi collateral markets.

100 Million Barrels Shrinkage? Reports Say EU Believes Oil Reserve Release Plan Mainly Fulfills Previous Commitments, Not New Quotas
Last Friday, G7 member countries agreed to release up to 100 million barrels of crude oil and diesel reserves. The IEA had announced a plan to release 400 million barrels in March, and as of last Friday, about 75 million barrels had yet to be released. Most EU member states believe that this action is simply fulfilling previous commitments rather than adding new releases. Regarding the earlier-than-scheduled release of diesel stocks emphasized in last week's G7 agreement, EU member states consider it feasible, but on a limited scale.
