Ethereum Layer 2 scaling network cross-chain bridge Taiko is back online, just 10 days after the June 22 hack.
The protocol halted operations after the attack, which resulted from a compromised SGX signing key mistakenly exposed on GitHub. The flaw allowed an attacker to forge withdrawal proofs, draining approximately $1.7 million from Bridge and ERC20 Vault 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 every user restored in less than two weeks.
“The bridge is open,” Taiko announced Thursday on
Taiko’s restoration of the bridge was the result of a multi-stage recovery that involved patching the vulnerability, rebuilding the bridge reserves to full 1:1 support, restoring Layer 2 network activity, and submitting the patch to an independent security review.
