INCIDENT EVIDENCE GRAPH
Taiko Bridge hacked — $1.70M lost
On June 21-22, 2026, Taiko (an Ethereum L2) suffered a bridge exploit targeting its ERC20 Vault. Attackers exploited a compromise in the chain state verification mechanism by forging SGX proofs to register a malicious prover, bypassing verification to submit fake bridge messages and drain approximately $1.7 million in assets (including USDC, ETH, and TAIKO tokens). Taiko quickly confirmed the verification compromise, paused the bridge and block production, initially urged users to withdraw funds, and later contained the incident while coordinating with exchanges to freeze attacker assets. A full post-mortem is forthcoming.
- Victim: Taiko Bridge
