- Type: Market stress
- Stage: Recovery reported
- Evidence: confirmed
- Materiality: material
- Event date: 2025-12-09
- Version: 1, published 2026-08-22 (first published 2026-08-22)
- Advisor-relevant: yes
- Affects: Base canonical bridge (protocol)

## What happened

Base experienced a high rate of missed blocks. Transactions submitted during missed blocks were delayed until a subsequent successful block, after which the condition resolved without a reported intervention.

## What changed

The incident added a confirmed transaction-inclusion disruption to Base's operating history, followed by recovery and preparation of a mitigation for recurrence.

## What did not change

The status record does not report a canonical-bridge contract exploit, fund loss, withdrawal pause, state reorganization, or permanent change to bridge mechanics.

## Confirmed

- Base reported a high rate of missed blocks.
- Transactions sent during missed blocks were delayed until the next successful block.
- Base reported that the issue resolved itself.
- Base said it prepared a mitigation for use if the issue returned.

## Still open

- The status record does not state the root cause or incident duration.
- It does not quantify missed blocks, delayed transactions, or affected users.
- It does not establish whether any canonical-bridge deposits, proofs, or withdrawal finalizations were delayed.

## What it means for an advisor

- Record the event in the Base canonical bridge's chain-liveness history.
- Monitor recurrence because bridge use depends on Base transaction inclusion even when bridge contracts remain intact.
- No approval restriction is supported by this isolated, recovered incident, but repeated missed-block events would warrant review.
