Summary

On June 22, 2026, Taiko — an Ethereum-equivalent layer-2 rollup — suffered a bridge exploit in which an attacker drained approximately $1.7 million from its L1 Bridge and ERC-20 vault by using an RSA-3072 Intel SGX signing key that had been committed in plaintext to the public taikoxyz/raiko GitHub repository. The attacker used the key to register as a legitimate prover, forge L2 state attestations, and execute fraudulent withdrawal transactions on Ethereum with no corresponding deposits on Taiko's chain. Taiko halted block production network-wide, froze affected contracts, and urged all users to exit every bridge on the network within approximately eight minutes of the attack being detected by Blockaid's monitoring system.

    “Taiko fully restored its cross-chain bridge on July 2, 2026 — 10 days after the $1.7M exploit — following an independent security review. CoinDesk confirmed bridge reopening July 2, 2026. Taiko's token rose 136% post-recovery, suggesting market confidence in the fix. Update is relevant to the existing taiko-ethereum-l2-bridge page.”
