Across Protocol hacker-linked address returns 331.8 ETH after $3.6 million Solana hack

Across Protocol flagged the on-chain transfer from an attacker-linked wallet, but the move alone does not show the incident is fully resolved or that users have been reimbursed.

Fact Check

Three independent crypto news sources (PANews, Coincu, CoinNess) all report on July 28, 2026 that an attacker-linked address returned 331.8 ETH to the Across Protocol multisig, citing PeckShield, following a ~$3.6M loss connected to a Solana hack. The claim's key facts—331.8 ETH returned, the $3.6M figure, and that the transfer does not confirm full resolution/reimbursement—are all directly supported. The Coincu piece explicitly states the move alone does not confirm reimbursements or a closed investigation, matching the claim's caveat. A minor discrepancy exists in the dollar value of the returned ETH (CoinNess ~$623,900 vs PANews ~$6.24M), but the 331.8 ETH quantity is consistent. I could not directly load the primary Across Protocol X announcement, slightly limiting confidence.

Summary

An attacker-linked address has returned 331.8 ETH in a partial recovery tied to the earlier Across Protocol hack that cost the protocol about $3.6 million on the Solana network. Across Protocol surfaced the on-chain movement through its X account, marking a shift from outright loss toward recovery, but the transfer alone does not establish that all funds were returned or that the incident is closed. Questions around the protocol’s net losses, any reimbursement plan, and the final destination or handling of the recovered ETH remain unresolved from the available record.
