Key Takeaways:
The Solana Foundation is lending USDT to Aave and plans to integrate the AAVE token onto its network, a significant cross-chain intervention aimed at stabilizing the decentralized finance sector after a major exploit rocked the Aave protocol.
"For Solana to be healthy, all of defi has to be healthy," Solana Foundation Chair Lily Liu said on X, framing the move as a collaborative push for open finance under the banner "DeFi United."
The intervention follows the April 18 KelpDAO exploit, which left Aave with an estimated $124 million to $230 million in bad debt from unbacked rsETH. The coordinated recovery effort, dubbed "DeFi United," also involves a proposal to the Arbitrum DAO to release 30,765 ETH ($95 million) in frozen exploiter funds and a planned 25,000 ETH ($77 million) contribution from Aave itself to help restore backing for the rsETH token.
This marks a strategic decision by a major layer-1 foundation to deploy treasury funds to support a protocol on a rival blockchain, prioritizing broader ecosystem health over direct competition. The move comes as Aave is expected to deploy its V3 protocol on Solana, which would bring one of DeFi's largest lending markets directly onto the network and give it a new source of total value locked (TVL).
The Solana Foundation's loan is one part of a multi-pronged effort to address the fallout from the KelpDAO exploit, the largest hack of 2026. An attacker minted 116,500 rsETH on Ethereum without backing, creating a shortfall of approximately 76,127 rsETH across the DeFi ecosystem, with Aave being the most affected.
In response, Aave, KelpDAO, LayerZero, and other protocols have organized to pool resources. They are actively pursuing the release of 30,765 ETH frozen on the Arbitrum network by its Security Council, which represents a significant portion of the funds needed to re-collateralize the rsETH token. Aave's own treasury is also contributing 25,000 ETH to the effort.
While the USDT loan amount from the Solana Foundation was not disclosed, the gesture signals a new level of cross-chain cooperation in crisis management. By stepping in to support Aave on Ethereum, the Solana Foundation aims to mitigate contagion risk and reinforce confidence in the broader decentralized finance space, even as it stands to benefit from Aave's eventual deployment on its own network.
