Taiko’s cross-chain bridge, Ethereum’s Layer 2 scaling network, is back online, just 10 days after the June 22 hack.
The protocol halted operations following the attack, which was due to a compromised SGX signing key mistakenly exposed on GitHub. The flaw allowed an attacker to falsify withdrawal proofs, draining approximately $1.7 million from the ERC20 Vault bridge and contracts.
Bridging exploits involving exposed keys remain a persistent challenge in crypto, with hundreds of millions lost across the industry in 2026. However, Taiko’s rapid recovery stands out, with all users recovered in less than two weeks.
“The bridge is open,” Taiko announced on X on Thursday. “You can move funds to and from Taiko again. Our response is complete: the network is fully restored and all users are complete. Any limits set will not affect normal usage. A reminder: we will never text you first, and there is no claim site. Just trust this account,” he added, promising to publish a full post-mortem of the incident soon.
Taiko’s restoration of the bridge is the result of a multi-stage recovery that involved patching the vulnerability, replenishing the bridge reserves to a full 1:1 backup, restoring Layer 2 network activity, and subjecting the fix to an independent security review.
