TL;DRAave Labs has proposed a V4 market built around institutionally custodied collateral.Bitcoin would remain with Anchorage while an on-chain receipt represents the collateral.Chainlink infrastructure would keep custody data synchronized with 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 create a new Aave V4 setup designed specifically for assets held with institutional custodians.In the initial model, Bitcoin would remain at Anchorage Digital Bank.The borrower would then receive an on-chain representation of that balance which could be posted into Aave.The Bitcoin Does Not Move Into AaveThat is the part that makes the design interesting.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.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.DeFi Keeps Meeting Institutional CustodyThis model gets at 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.The asset stays inside a regulated custody environment while DeFi handles the credit side.That also creates new dependencies.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.Source: Aave governance proposal — https://governance.aave.com/t/arfc-custodied-collateral-lending-aave-v4-isolated-hub-spoke/25639This article was written by the News Desk and edited by Samuel Rae.This report is based on information released by Governance. at Governance
