Aave Labs has proposed a new Aave V4 lending market that lets institutions borrow against Bitcoin without moving it out of Anchorage Digital Bank's custody. A non-transferable token, synchronized by Chainlink infrastructure, would represent the custodied Bitcoin on-chain so borrowers can draw stablecoins from an isolated Aave hub. The idea is still at the governance discussion stage.
Bitcoin stays at Anchorage, not in Aave
Aave Labs is exploring a lending structure that would let institutions borrow on-chain without first moving their Bitcoin out of regulated custody. The proposal, titled "Custodied Collateral Lending: Aave V4 Isolated Hub & Spoke," would build a new Aave V4 setup specifically for assets held with institutional custodians. In the initial model, Bitcoin would remain at Anchorage Digital Bank, and the borrower would receive an on-chain representation of that balance that could be posted into Aave.
That structure sets this proposal apart. Aave is not proposing a standard wrapped-Bitcoin market where BTC is bridged into a token and deposited into a DeFi contract; instead, the underlying asset stays with Anchorage for the life of the loan. A non-transferable Custodied Collateral Token, or CoCT, represents the position on-chain, and Chainlink's proposed CustodySync infrastructure would mint and burn the token as the custodied balance changes, keeping the off-chain custody account and the Aave lending position aligned. The borrower could then draw stablecoins from the isolated Aave V4 hub.
A recurring problem for institutional DeFi
The model addresses a problem institutional crypto has wrestled with for years: large holders may want access to on-chain liquidity, but moving assets out of qualified custody can create compliance, security and operational headaches. A custodied-collateral model tries to split the difference, keeping the asset inside a regulated custody environment while DeFi handles the credit side. That also creates new dependencies, since Aave would need to trust that custody information is synchronized accurately and quickly enough for lending and liquidation decisions.
The proposal is still in the governance discussion stage, so none of this should be treated as a live Aave market yet. But the architecture is revealing: DeFi's next institutional growth phase may not require banks and funds to abandon traditional custody. It may instead involve building reliable bridges between custody systems and on-chain lending markets.
