Summary

Taiko (ticker: TAIKO) is an Ethereum-equivalent, based contestable ZK-rollup Layer 2 developed by Taiko Labs, founded in 2022 by Daniel Wang, former founder of Loopring. The protocol launched on Ethereum mainnet on May 27, 2024 and raised $37 million in total funding. On June 22, 2026, an attacker exploited a critical operational security failure — an SGX RSA-3072 private signing key committed to a public GitHub repository — to forge valid L2 state attestations and drain approximately $1.7 million from the L1 Bridge and ERC20Vault contracts; Taiko halted block production, paused all bridge withdrawals, and pledged full treasury-backed reimbursement to affected users.
