Layer-2 blockchain project Taiko has issued an urgent security warning after confirming that its chain state verification mechanism was compromised. This puts the security of all bridges deployed on the network at risk.
The incident has already resulted in losses of more than $1 million, according to blockchain security firm Blockaid. It has prompted Taiko to advise users to immediately withdraw funds from affected bridges.
Taiko Confirms Verification Mechanism Compromise
In an official statement posted on X, Taiko revealed that its chain state verification mechanism had been compromised. As a result, the security assumptions behind all bridges running on the network can no longer be trusted.
The team stated, “We have confirmed a compromise of Taiko’s chain state verification mechanism. As a result, the security assumptions of all bridges deployed on Taiko can no longer be relied upon.”
Taiko said it is actively working with its Security Council and ecosystem partners to contain the incident. It is also pausing affected systems where possible, and taking all necessary technical and legal measures.
As a precaution, Taiko strongly urged users to withdraw funds from all bridges deployed on the network without delay.
The project also made an urgent request to centralized exchanges to suspend TAIKO deposits until further notice. This aims to prevent additional risks while the investigation continues.
Taiko published several wallet addresses linked to the attacker. This gives exchanges and investigators a chance to track suspicious fund movements and potentially freeze stolen assets.
More Than $1 Million Lost in ERC20 Vault Attack
Before Taiko’s announcement, blockchain security platform Blockaid reported that Taiko’s ERC20 Vault on Ethereum had been attacked. The losses had already exceeded $1 million at that time.
Meanwhile, initial reports show the exploit originated from a vulnerability in the bridge’s source-signal proof verification mechanism. This is a critical component used to validate cross-chain transactions.
The full extent of the damage remains unclear, and Taiko said investigations are still ongoing.
What Could Happen Next?
However, the incident could put some pressure on the TAIKO token in the near term.
Historically, cross-chain bridges have been among the crypto industry’s biggest security weak points. Bridge exploits have accounted for billions of dollars in losses over the years. Moreover, more than 20 crypto hacks were reported in June alone, according to DeFiLlama data. Thus, the Taiko incident adds to growing concerns surrounding blockchain security.
For now, Taiko’s recovery will likely depend on how quickly the team can resolve the vulnerability. They must also restore trust in its bridge infrastructure, and potentially recover stolen funds.
