Euler notifies user of $73K in unclaimed ETH from recovery process

Someone out there has $73,000 in ETH just sitting in a wallet, waiting to be claimed. They’ve been pinged about it. They haven’t responded. And they’re not alone.

Euler Finance recently notified a user via onchain messaging that 32.3 ETH from the protocol’s 2023 hack recovery remains unclaimed. The wallet in question has been completely inactive since April 2023.

The backstory: a $197 million hack with a surprisingly happy ending

On March 13, 2023, Euler Finance’s V1 protocol was hit with one of the largest exploits of the year. Roughly $197 million in assets, including DAI, USDC, WBTC, and stETH, were drained in the attack.

The hacker, who identified themselves as “Jacob,” actually returned the stolen funds. By April 4, 2023, the assets were fully recovered, with the total value reportedly reaching around $240 million when accounting for price appreciation during the negotiation period.

To redistribute the recovered funds, Euler set up a Merkle-tree-based claim contract called EulerClaims. If you were affected by the hack, you could verify your eligibility and withdraw your share of the recovered assets. The contract was designed to work with both standard wallets (externally owned addresses, or EOAs) and multisignature wallets.

149 ETH still unclaimed across 1,636 addresses

According to data from Forgotten ETH, a tracker that monitors unclaimed assets on Ethereum, approximately 149.13 ETH remains unclaimed across 1,636 eligible addresses from Euler’s recovery distribution. At current prices, that’s a meaningful chunk of value scattered across wallets whose owners have apparently moved on, lost access, or simply never noticed.

The 32.3 ETH wallet that prompted Euler’s recent notification represents the single largest unclaimed balance in the recovery pool. At roughly $73,000, the notification was sent via an onchain Input Data Message (IDM), which is essentially a note embedded in a transaction that the wallet owner would see if they checked their address on a block explorer like Etherscan. The wallet has shown zero activity for nearly two years.

The EulerClaims contract remains open with no reported pauses or deadlines, which means eligible users can still claim their funds whenever they decide to show up.

What this means for investors

For anyone who interacted with Euler Finance’s V1 protocol before March 2023, the practical takeaway is simple: check your eligibility. Tools like Forgotten ETH exist specifically to surface these kinds of overlooked assets. The claims contract is still live, and there’s no indication it’s closing anytime soon. That said, “no indication” is not the same as “guaranteed forever,” so procrastination carries its own quiet risk.
