Taiko fully restores cross-chain bridge just 10 days after a $1.7 million hack

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.

The bridge has been reopened under conservative withdrawal quotas to ensure stability.

The crypto market is cheering the swift resolution. The TAIKO token has surged as much as 136% in recent trading, reflecting strong relief among holders after the protocol demonstrated effective containment and full user protection.
