Key Highlights
- Taiko completed Step 1 of its four-phase recovery plan after the bridge security incident.
- The Security Council successfully deployed on-chain fixes on June 29.
- Taiko confirmed no forged checkpoints or attacker claims remain reachable.
Taiko, an Ethereum Layer 2-based rollup, has completed the first step of its staged recovery plan following a security incident earlier this month that compromised its chain state verification mechanism and resulted in approximately $1.7M being drained.
In an X post on Monday, the team said the Taiko Security Council executed the on-chain proposal to deploy critical fixes. The transaction, visible on Etherscan, confirms the action was successful.
According to Taiko, the chain’s finalized state now checks out cleanly, with no forged checkpoints or attacker claims left reachable. This marks the completion of Step 1 in a carefully structured four-phase recovery process.
The incident was publicly disclosed on June 22, when Taiko announced that its chain state verification mechanism had been compromised. The team immediately advised users to withdraw funds from bridges deployed on Taiko as a precautionary measure and began coordinating with the Security Council and partners to contain the issue.
How the recovery plan would unfold
In a June 28 update, Taiko said it was “ready to come back online” after independent security experts reviewed the fixes. The team outlined a staged recovery plan designed to minimize risk and prioritize user safety:
- Deploy fixes and verify the finalized chain state (now completed).
- Replenish the bridge to ensure every L2 asset is backed 1:1, verifiable on-chain.
- Restart network operations, including transfers, swaps, and trading on L2.
- Reopen the bridge with conservative withdrawal quotas initially for added safety.
“No user will lose funds. We’re coming back stronger than before,” Taiko said.
The team said the phased approach is intended to rebuild confidence while reducing the risk of similar issues during the recovery process.
What’s next for Taiko users
The incident highlights the operational challenges facing Layer 2 networks, where bridging mechanisms and rollup designs require robust verification systems.
As Taiko moves to Step 2, bridge replenishment, the community will be closely watching on-chain verifications to confirm 1:1 backing of assets. Once the network resumes full operations and the bridge reopens, users should be able to move funds freely again, albeit initially under cautious withdrawal limits.
If the remaining steps proceed as planned, Taiko could return to full operations within the coming days.
Bridge security remains in focus
Although Taiko has completed the first phase of its recovery, the incident has drawn attention to the security challenges associated with bridge infrastructure and state verification systems. The staged recovery process, including bridge replenishment and temporary withdrawal limits, illustrates the complexity of restoring network operations following a security breach.
As recovery continues, the effectiveness of the remaining phases will likely be closely monitored by users and the broader Ethereum Layer 2 ecosystem.
