Across Protocol Hit with $4.5M Exploit, User Funds Remain Safe
The cross-chain bridge protocol Across (ACX) recently suffered an exploit resulting in the loss of approximately $4.5 million.
The team confirmed that user funds were not compromised and remain safe, with the scheduled ACX buyback plan proceeding as planned.
The incident was attributed to a bug in the relay software responsible for reading off-chain events on the Solana (SOL) network.
A bug in the relay software allowed an attacker to forge deposit events that never actually occurred, tricking the relayer into treating them as legitimate transactions and draining approximately $4.5 million from the relayer's reserves.
