Taiko Cross-Chain Bridge Restored After $1.7 Million Hack
Taiko, an Ethereum layer-2 scaling network, has successfully restored its cross-chain bridge just 10 days after a $1.7 million hack. The bridge was taken offline after the attack, which occurred on June 22, due to a compromised SGX signing key that was mistakenly exposed on GitHub. This flaw allowed an attacker to forge withdrawal proofs, resulting in the loss of approximately $1.7 million from the bridge and ERC20 Vault contracts.
The quick recovery of Taiko’s cross-chain bridge is notable, especially considering that bridge exploits involving exposed keys remain a significant challenge in the crypto industry, with hundreds of millions of dollars lost in 2026. Taiko’s response to the hack has ensured that every user has been made whole in under two weeks, demonstrating the network’s commitment to security and user trust.
Restoration and Security Measures
Taiko announced the restoration of the bridge on X, stating that users can now move funds to and from Taiko again. The network has completed a multi-stage recovery process, which included patching the vulnerability, replenishing bridge reserves, restoring layer-2 network activity, and undergoing an independent security review. Taiko has also reminded users to be cautious of potential scams, stating that they will never initiate direct messages and that there is no claim site.
