Aave proposes custodied collateral lending framework for institutions
In brief
- Aave Labs published governance proposal 'Custodied Collateral Lending: Aave V4 Isolated Hub & Spoke' on September 14.
- Institutions can borrow stablecoins against Bitcoin held in Anchorage Digital custody without moving collateral on-chain.
- Custodied Collateral Tokens (CoCTs) represent custodied assets on-chain via Chainlink CustodySync infrastructure.
- Liquidations occur as over-the-counter sales, keeping institutional lending separate from retail pools.
How it works
The framework introduces Custodied Collateral Tokens (CoCTs), ERC-20 tokens minted to represent custodied assets on-chain but remain non-transferable. The minting and burning of these tokens runs through Chainlink's CustodySync infrastructure, creating a bridge between off-chain custody and on-chain lending logic.
Bitcoin is specified as the initial collateral type in the proposal. When liquidations occur, they're conducted as over-the-counter sales rather than public auctions—a key difference from traditional DeFi liquidation mechanics that keeps institutional risk management distinct from retail market dynamics.
Institutional isolation and custody
The proposal creates an Isolated Hub and Spoke system under Aave V4 architecture. Rather than bolting institutional features onto Aave's existing lending pools, this design keeps institutional lending separate from the protocol's permissionless retail markets. That separation reduces systemic risk and allows for tailored risk parameters suited to institutional borrowers.
Anchorage Digital, a federally chartered crypto bank with an OCC national trust bank charter, is enhancing its Atlas collateral management platform to enable collateral management in lending frameworks without requiring assets to move out of segregated custody. This addresses a long-standing institutional concern: regulatory compliance and operational security during lending.
Governance and precedent
The proposal still needs approval from Aave DAO token holders through the governance process. Existing models have been successfully implemented by protocols like Ethena and Kamino, which facilitate institutional lending against various asset reserves. The Aave proposal builds on those patterns while introducing new infrastructure for custody integration.
