Taiko Exploit Adds to June Tally of Over 20 Crypto Hacks

Taiko lost roughly $1.7 million on Monday after an attacker compromised the chain-state verification mechanism. 

The latest hack adds to the growing list of attacks targeting crypto networks in 2026.

Taiko Becomes Latest of 20-Plus Crypto Hacks This June

Taiko runs as an Ethereum-equivalent-based rollup that settles its activity back to the mainnet. Earlier today, Blockaid flagged an ongoing exploit in a post on X (formerly Twitter).

Taiko confirmed the compromise in a security notice and warned that bridge security assumptions could no longer be trusted.

Meanwhile, on-chain data shared by Lookonchain shows the attacker has already started cashing out. The wallet moved 1.99 million TAIKO, worth about $189,000, to MEXC. The same address still holds 870.8 ETH valued at nearly $1.52 million. 

Taiko said it is working with its Security Council and ecosystem partners to contain the incident. In addition, Taiko signaled that it may take technical and legal action against the attacker.

The team has asked centralized exchanges to suspend TAIKO deposits until it issues an official all-clear.

“We strongly advise all users to withdraw their funds from all bridges deployed on Taiko immediately,” the team said.

Meanwhile, it also shared 4 attacker addresses:

• 0x7506DeA0c38ca0B55364B22424374c5A1ae1B76a  
• 0x5fbc60a12bc6635e7d587d8dac52e4b1388b4990   
• 0x3cc936b795a188f0e246cbb2d74c5bd190aecf18   
• 0x9108828e30f2de407aadb0af677b4a9228e4acd4

Historically, bridges have ranked among crypto’s costliest weak points, and 2026 has been no exception. A tracker from DefiLlama counts more than 20 crypto hacks in June alone.

The published addresses of attackers give investigators a trail to follow as funds move. Whether Taiko can recover the stolen assets may hinge on how fast exchanges freeze the flagged wallets.
