Key Takeaways:
Circle’s Chief Economist Gordon Liao proposed elevating USDC’s Aave V3 Slope 2 price to 50% to revive liquidity after a KelpDAO exploit. A $292 million KelpDAO rsETH bridge assault on April 18 drained Aave of as much as $15.1 billion in TVL inside days. Aave’s USDC pool sat at 99.87% utilization for 4 days, with underneath $3 million in out there liquidity as of April 22.
Circle Chief Economist Proposes Greater USDC Charges on Aave V3 to Restore Liquidity After KelpDAO Exploit
The proposal, filed as an Aave Request for Remark, asks Aave’s Threat Steward to right away increase Slope 2 from 10% to 40% and decrease optimum utilization from 92% to 87%. A follow-on governance vote would push Slope 2 to 50% and optimum utilization to 85%. At 100% utilization underneath the goal configuration, USDC debtors would face a most price of roughly 53.5%, in comparison with the present ceiling of roughly 14%.
Liao, who famous his views are private and never official Circle coverage, tied the proposal on to the April 18 KelpDAO rsETH exploit. Attackers exploited a vulnerability in KelpDAO’s bridge to siphon unbacked rsETH, deposit it as collateral on Aave V3, and borrow an estimated $200 million to $300 million in belongings, together with WETH and stablecoins. Aave froze rsETH markets on V3 and V4 to restrict additional harm, however not earlier than triggering what grew to become a widespread liquidity disaster.
The fallout was extreme. Aave’s complete worth locked (TVL) shed billions in a matter of days. Core markets, together with ETH, USDT, and USDC hit 100% utilization, successfully trapping depositor funds. Some customers resorted to borrowing in opposition to stablecoins like GHO, DAI, and USDe to entry liquidity not directly.
The USDC pool grew to become a focus. In accordance with Aavescan knowledge from April 22, complete provide and borrows every sat close to $1.89 billion, with out there liquidity beneath $3 million. The pool had been pinned at roughly 99.87% utilization for 4 days, with variable borrow charges capped close to 13.82% and provide charges round 12.42%.
Liao’s proposal frames the flat post-kink price because the core downside. As a result of the present Slope 2 is low, rate-insensitive debtors handled the roughly 14% price as a charge to bypass queues fairly than a sign to exit. The end result was a market that didn’t clear whilst depositors tried to withdraw.
Elevating the kink-slope steeply, Liao argued, would allow worth discovery, deter debtors detached to price ranges, and entice new USDC provide inside hours. He cited Treasury repo and fed funds markets as precedent for a way steep curves resolve short-term liquidity dislocations.
Circle CEO Jeremy Allaire publicly shared the proposal on X, drawing broader consideration to the governance dialogue. Threat service suppliers Llamarisk and Aave Labs have been recognized as key contributors anticipated to weigh in.
AAVE’s token worth fell roughly 20% to 26% within the days following the exploit amid the outflow wave. The governance proposal has been interpreted by some market observers as a stabilizing sign.
The KelpDAO incident didn’t compromise Aave‘s good contracts straight. The vulnerability originated in KelpDAO’s cross-chain bridge infrastructure. However the episode uncovered how unbacked collateral getting into by means of bridge exploits can generate unhealthy debt at a protocol degree, with estimates of unrecoverable losses starting from $124 million to $230 million throughout Aave markets, relying on how losses are in the end distributed.
Aave printed an rsETH incident report outlining restoration paths. Discussions about potential unhealthy debt absorption by means of mechanisms like slashing stkAAVE are ongoing.
Liao’s two-phase method retains Slope 1 at 3.5%, the bottom price at 0%, and the reserve issue at 10% unchanged. The interim Threat Steward motion may take impact the identical day if accredited, whereas the complete goal configuration requires a normal five-to-seven-day governance vote.
