## What happened

Base reported periodically delayed blocks during volatile activity and marked the incident resolved after degraded block building and transaction inclusion between 14:45 and 15:10 UTC.

## What changed

Transaction inclusion on the chain supporting the watched canonical bridge was temporarily less reliable, adding a confirmed operational incident to the bridge diligence record.

## What did not change

The status record does not report a bridge-contract exploit, fund loss, withdrawal pause, challenge-period change, or continuing impairment after resolution.

## Confirmed

- Base's official status page marked the incident resolved.
- The reported degradation occurred between 14:45 and 15:10 UTC on 2026-01-20.
- Users may have experienced delayed transaction inclusion and degraded block-building performance.

## Still open

- The status record does not quantify affected transaction volume or identify whether any canonical-bridge transactions were specifically delayed.
- The record attributes the condition to volatile activity but provides no detailed root-cause analysis.

## What it means for an advisor

- Add the incident to the Coinbase Bridge operational-reliability record and review recurrence before the next memo decision.
- No kill criterion is confirmed by this short resolved delay, but stressed exits should continue to account for sequencer and inclusion risk.
