Ethereum layer-2 scaling network Taiko’s cross-chain bridge is back online, just 10 days after the June 22 hack.
The protocol ceased operations following the attack, which originated from a compromised SGX signing key that was mistakenly disclosed on GitHub. The flaw allowed an attacker to forge withdrawal proofs and drained around $1.7 million from the bridge and ERC20 Vault contracts.
Bridge exploits involving exposed keys remain an ongoing challenge in crypto, with hundreds of millions lost across the industry by 2026. But Taiko’s quick recovery stands out, with every user healed in less than two weeks.
“The bridge is open,” Taiko announced on X Thursday. “You can move money to and from Taiko again. Our response is complete: the network is fully restored and every user is whole. Any restrictions in place will not affect normal use. A reminder: we never send you DM first and there is no claim page. Only trust this account,” it added, promising to publish a full post-mortem of the incident soon.
Taiko’s recovery of the bridge is the result of a multi-step recovery that involved patching the vulnerability, replenishing bridge reserves to full 1:1 backing, restoring layer-2 network activity, and submitting the fix to an independent security review.
