Taiko halts its network after a bridge exploit
Taiko halted its Ethereum L2 on June 22 after an attacker forged cross-chain withdrawal proofs to drain approximately $1.7 million from the bridge and token vault. BlockSec traced the root cause to an exposed Raiko SGX enclave signing key committed to GitHub, which allowed the attacker to generate fabricated proofs the verifier accepted. The TAIKO token dropped over 20% as the team froze withdrawals, halted block production, and urged exchanges to suspend deposits, with approximately $170,000 in tokens moving to MEXC before containment. The incident adds to a 2026 tally of 14+ bridge exploits totaling over $340 million in losses, following forged cross-chain messaging attacks against Kelp DAO ($292 million) and the Verus-Ethereum bridge ($11.4 million) earlier this year.
