Ethereum layer-2 scaling network Taiko’s cross-chain bridge is back online, just 10 days after the June 22 hack.
The protocol halted operations after the attack, which stemmed from a compromised SGX signing key mistakenly exposed on GitHub. The flaw enabled an attacker to forge withdrawal proofs, draining roughly $1.7 million from the bridge and ERC20 Vault contracts.
Bridge exploits involving exposed keys remain a persistent challenge in crypto, with hundreds of millions lost industry-wide in 2026. However, Taiko’s quick recovery stands out, with every user made whole 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 every user is whole. Any limits in place won’t affect normal use. A reminder: we’ll never DM you first, and there’s no claim site. Only trust this account,” it 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 bridge reserves to full 1:1 backing, restoring layer-2 network activity, and subjecting the fix to an independent security review.
