Taiko warns users to withdraw from bridges after a verification compromise and reported ERC20 Vault losses above $1M.
Taiko has issued an urgent security warning after confirming a compromise in its chain state verification mechanism.
The project said the issue affects the trust model behind bridges deployed on Taiko.
The team warned that users can no longer rely on normal bridge security assumptions. As a result, it advised users to withdraw funds from all Taiko-based bridges immediately.
Taiko said it is working with its Security Council and ecosystem partners to contain the incident. The response includes pausing affected systems where possible and carrying out technical checks.
The warning followed reports that Taiko’s ERC20 Vault on Ethereum was attacked. Blockaid said losses exceeded $1 million, with early findings pointing to a bridge verification flaw.
Taiko Confirms Verification Mechanism Compromise
Taiko said the issue affected its chain state verification mechanism. This process helps confirm cross-chain activity across bridge systems.
Because of the compromise, the team warned that bridge safety can no longer be trusted.
⚠️ Security Notice
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.
We are actively coordinating with the Security Council and ecosystem partners to…

The project said it is working with its Security Council and ecosystem partners. It is also trying to contain the incident and pause affected systems where possible.
These steps aim to limit further exposure while technical checks continue. Taiko said it is taking both technical and legal actions linked to the incident.
However, the team has not released a full technical report yet. Further updates are expected after the project gathers more details.
Users and Exchanges Receive Immediate Guidance
Taiko strongly advised users to withdraw funds from all bridges deployed on the network. The warning applies to users with assets held in bridge contracts. It also covers users exposed to related cross-chain systems.
The team also asked centralized exchanges to suspend TAIKO deposits until further notice. This step could help prevent new deposits from entering systems under review. It also gives exchanges time to check wallet and bridge exposure.
Bridge issues can move quickly because assets rely on messages between chains. If verification fails, attackers may target vaults or withdrawal routes. Therefore, Taiko placed user withdrawals ahead of a longer public review.

ERC20 Vault Attack Adds Pressure to Bridge Review
Security firm Blockaid earlier reported an attack on Taiko’s ERC20 Vault on Ethereum.
Reports placed losses at more than $1 million. Early findings linked the issue to source-signal proof verification.

Preliminary analysis suggested that forged messages passed checks on Ethereum mainnet.
That allowed unauthorized withdrawals without a valid MessageSent event from Taiko. The reported method placed the bridge design under closer review.
The incident adds fresh concern around bridge safety in crypto markets. Cross-chain systems often hold large pools of user funds.
For now, Taiko’s main instruction remains to withdraw funds and wait for official updates.
