Key Highlights
- Etherscan flagged an address with 32.3 ETH in unclaimed assets tied to Euler Finance’s post-exploit recovery process.
- The wallet owner was notified through an onchain Input Data Message, with the message pointing to Forgotten ETH for verification.
- Forgotten ETH data shows 149.13 ETH remains unclaimed across 1,636 Euler redemption addresses.
Etherscan, the block scanner built for Ethereum has flagged a dormant wallet with 32.3 ETH in unclaimed assets linked to Euler Finance’s post-exploit redistribution process. At an ETH price near $1,777, the claim is worth roughly $57,400.
The blockchain explorer said the assets had been sitting idle since April 2023. The wallet owner was recently notified through an onchain Input Data Message, or IDM, asking them to verify a claim tied to Euler’s recovery process.
Etherscan lists Input Data Messages (IDM) Beta among its explorer services, allowing messages to be attached and viewed through Ethereum transaction input data.
Claim Tied to Euler’s 2023 Exploit Recovery
The claim traces back to Euler Finance’s March 2023 exploit, one of DeFi’s largest security incidents. Euler later said its V1 protocol was exploited for about $197 million, while its recovery effort led to the return of roughly $240 million in stolen assets.
Euler’s claim contract was built to let users redeem funds that were stolen during the March 13, 2023 hack and later recovered. The GitHub repository describes EulerClaims as a Merkle-tree-based distributor that can be used by EOAs and multisig wallets.
149 ETH Still Unclaimed Across Euler Redemptions
Forgotten ETH’s Euler Redemptions dashboard shows that recovered funds were distributed through a one-shot Merkle-drop contract deployed in July 2023. Each eligible depositor’s index pays out a basket of assets, including WETH, DAI, USDC, COMP, and other tokens, based on pre-exploit holdings.
The dashboard shows 149.13 ETH still unclaimed across 1,636 addresses, worth about $265,000 at current ETH prices. The contract remains unpaused, and Forgotten ETH says eligible users can still claim with the original index and proof.
The case shows how DeFi recovery funds can remain untouched long after an exploit has been resolved. Euler’s recovery was considered rare because the protocol recovered the stolen assets, but some users still appear to have missed or ignored their claim windows.
It also highlights a broader issue in Ethereum: old contracts can still hold claimable balances even when frontends, scripts, or user awareness disappear. Forgotten ETH says it scans hundreds of defunct or forgotten contracts and lets users verify claims directly, while also noting that withdrawals can be done manually through Etherscan.
What’s Next
The immediate watch is whether the wallet owner responds to the onchain message and claims the 32.3 ETH. If the funds are claimed, Euler’s remaining unclaimed redemption balance should fall from the current 149.13 ETH shown on Forgotten ETH.
For users, the safer takeaway is verification. Any wallet owner checking old claims should confirm contract addresses, avoid unknown approvals, and verify claim paths directly through Etherscan or official contract data before signing transactions.
