Aave Labs proposed to deploy V4 isolated Hub for accessing custodial collateral

On September 14, Aave Labs released an ARFC on the Aave governance forum, seeking approval to deploy a new Aave V4 Isolated Hub and Spoke to integrate institutional custody collateral as collateral for stablecoin loans. Institutional borrowers will deposit collateral with Anchorage and maintain custody during the loan period, with the custody balance represented on-chain by non-transferable custody collateral tokens CoCT, minted and burned by CustodySync designed by Chainlink.

Borrowers will stake CoCT on the Spoke and withdraw stablecoins from the Isolated Hub. The entire loan lifecycle, including liquidation, is synchronized between the custodian and Aave through Chainlink infrastructure. The proposal is limited to a single Isolated Hub and a single Spoke governed by the Aave DAO, without altering existing Hubs, Spokes, or reserves. The underlying assets will always remain in custody, with Anchorage holding the assets as the custodian and acting as the counterparty for account control protocols; Chainlink does not hold the assets.

CoCT is a restricted transfer ERC-20, only allowing Hub, Spoke, and CustodySync, with minting and burning exclusive to CustodySync, and each borrower's position corresponding to a contract. The initial plan is to launch a CoCT for BTC held in custody by Anchorage. The next steps involve ARFC discussions, and if supported, it will proceed to Snapshot, followed by submitting the final parameters for AIP.
