Base Network Block Halt Issues, Reasons, Action, Preventions Explained

On 5 August 2025, there was a 33-minute block production stop on the Coinbase Base Network. This interference touched upon the key activities of deposits, withdrawals, and block production. The team solved the issue within a short amount of time and subsequently published a comprehensive incident report.

This is the full account of what went wrong, the cause of the glitch, the way it was solved, and how it plans to prevent such occurrences in the future.

What Happened to Base Network Yesterday ?

At 6:07 AM UTC on August 5, the mainnet abruptly halted block generation because of a problem in its sequencer system. The sequencer is one of the most important elements that assist in maintaining the blockchain's functionality by creating new blocks.

This event resulted in a temporary halt of activity and a lot of users' questions. In a few minutes, the staff were notified and started solving the problem.

What Are the Confirmed Reasons Behind the Issues?

The team’s postmortem revealed a clear chain of events that led to the disruption:

• Network runs on a Highly Available (HA) cluster of sequencers managed by a system called Conductor.

• At 6:07 AM UTC, the active sequencer lagged behind due to heavy on-chain activity.

• The conductor triggered an automatic handoff to another sequencer.

• Unfortunately, the new sequencer was not fully ready, so it couldn’t create blocks.

• Worse, the new sequencer couldn’t trigger another handoff because it didn’t have full Conductor access.

This led to a complete pause in block production until the team manually took over. So, the team confirmed that issues came from a misconfigured automatic handoff process.

What Steps Were Taken to resolve the Issue?

Once the issue was identified, the team paused the Conductor system to prevent more faulty handoffs. Then, they manually transferred leadership to a healthy sequencer. Proper care is taken to avoid chain reorganisation, which could have led to further issues. Around 6:40 AM UTC, the Mainnet was up and running again. The incident was declared resolved, and operations resumed normally.

What Are the Loopholes The Team Is Working On?

The team has identified key improvement areas to stop the same issue from happening again:

1. Upgrade Infrastructure: Ensure any newly added sequencer is always ready to lead.

2. Improve Testing: Deploy updates with more real-world testing to ensure automated systems don’t fail.
