Less than a day before Aave founder Stani Kulechov argued that DeFi may need to follow an “Uber path” where adoption grows faster than regulation, Aave Labs proposed a product that shows what that strategy could look like in practice.
The new Aave custodied collateral lending proposal would allow institutional borrowers to use assets held at regulated custodian Anchorage as collateral for stablecoin loans without moving those assets into Aave.
The initial rollout is deliberately narrow. One isolated Aave V4 Hub, one Spoke and one Custodied Collateral Token representing BTC held at Anchorage. Existing Aave markets and reserves would remain unchanged. The important part is therefore bigger than adding Bitcoin collateral. Aave is attempting to connect institutional assets that currently sit outside public DeFi to its lending liquidity while keeping the resulting risk in a separate credit environment.
Aave is targeting collateral DeFi cannot currently reach
Most DeFi lending assumes that users can move their collateral into an onchain protocol.
That assumption works for crypto native users. It becomes harder for institutions whose assets need to stay inside qualified custody or established operational frameworks.
Aave Labs describes these assets as collateral that is currently “unreachable” by Aave. Under the proposal, the institution keeps its BTC at Anchorage for the entire loan lifecycle. Chainlink CustodySync then synchronises that custody position with Aave.
The system creates a Custodied Collateral Token, or CoCT, representing the custodied balance. It is an internal accounting instrument rather than a freely tradable token and gives its holder no direct claim on the underlying BTC.
Once the position is synchronised, the institution can borrow stablecoins from the isolated Aave market.
That makes the proposal less about tokenising Bitcoin and more about making existing institutional custody compatible with onchain credit.
Custodied lending itself is not new. Anchorage already supports structures involving Spark, Ethena and Kamino where collateral remains under custody while institutions access crypto credit.
Aave’s differentiator is how V4 incorporates that model into a reusable protocol architecture controlled by the DAO.
V4 makes the risk isolation more important than the BTC
This is where the proposal becomes a useful demonstration of Aave V4 rather than another institutional partnership.
The custodied collateral would exist inside its own Isolated Hub and Spoke. Stablecoin liquidity enters through a lender facing Spoke, while CoCT can only be used as collateral inside the dedicated custodied collateral Spoke.
Aave Labs says there is no exposure path from that collateral into assets or reserves on other Hubs. CoCT also receives a permanent zero draw cap, preventing the receipt token itself from being borrowed out of the Hub.
This changes the growth equation.
Aave can potentially add a new class of institutional borrowers and the associated stablecoin demand without requiring existing Core users to share the same collateral risk.
That architecture matters because institutional growth becomes less useful if every new collateral type also increases systemic dependence inside a common liquidity pool. V4 gives Aave a way to expand credit demand while separating different risk domains.
The proposal therefore provides a clearer use case for the Hub and Spoke design than simply listing more assets.
Liquidations move away from public auctions
A second institutional friction point is liquidation.
Regular DeFi lending relies heavily on onchain liquidators competing to purchase collateral once a position breaches its required health level. That model is difficult to reproduce when the actual BTC remains inside regulated custody.
Aave’s proposal instead gives Anchorage responsibility for executing an OTC sale of the underlying collateral. Proceeds would then settle the debt onchain through a single atomic transaction.
Chainlink provides the coordination layer connecting custody balances, price data and Aave’s protocol state.
That arrangement introduces greater dependence on external infrastructure than ordinary fully onchain collateral. The counterbalance is isolation. Problems associated with the custodian, synchronisation system or a specific borrower are designed to remain inside the dedicated market rather than spreading through existing Aave reserves.
Final collateral factors, liquidation parameters, caps, interest rates and oracle settings have not yet been approved. The proposal remains at the ARFC stage and would still need Snapshot approval followed by an AIP before execution.
This is what Stani’s Uber path looks like as a product
The proposal arrived as Washington delivered another regulatory setback for crypto.
The U.S. Senate failed on September 15 to advance the CLARITY Act after the procedural vote fell short of the 60 votes required. The bill is stalled rather than definitively dead.
Memeburn has previously followed the CLARITY Act’s path through the Senate and how regulatory changes could affect DeFi platforms such as Aave and Uniswap.
Kulechov responded by arguing that DeFi may ultimately need an “Uber path” where widespread use forces policymakers to deal with the technology rather than the industry waiting for legislation first. He also said institutions “come with size” and could become an important source of borrowing demand.
Custodied collateral lending makes that argument tangible.
The thesis is no longer simply that institutions will eventually move their assets onchain. Aave can instead bring their borrowing demand onchain while allowing the collateral and custody relationship to remain where institutions already operate.
If that model scales beyond the first Anchorage BTC position, V4 starts to look less like another lending pool and more like a credit distribution layer connecting different forms of collateral to shared stablecoin liquidity.
That may be the more important part of the proposal.
FAQs
What is Aave custodied collateral lending
It is a proposed Aave V4 structure that would allow institutions to borrow stablecoins using collateral held with a regulated custodian instead of depositing the underlying asset directly into Aave.
Will institutions move their Bitcoin into Aave
No. Under the first proposed implementation, BTC remains with Anchorage. A nontransferable CoCT records the relevant collateral position inside Aave V4.
Is Aave custodied collateral lending already live
No. The proposal is currently an ARFC. It still requires community feedback, a Snapshot vote and an AIP with final risk parameters before it can be executed.
