Base has restored network stability after a misconfigured transaction propagation change triggered congestion, delays, and dropped transactions in late January, according to a network status update.
The incident began on Jan. 31, when the Ethereum Layer-2 network experienced elevated congestion that caused submitted transactions to be delayed or dropped. While blocks continued to be produced throughout the disruption, users reported unusually high confirmation latency.
Base said the issue stemmed from an infrastructure configuration change related to transaction propagation. The adjustment caused the block builder to repeatedly fetch transactions that could not be executed as base fees rose rapidly. As a result, transactions were reprocessed inefficiently, creating a feedback loop in the transaction pipeline under volatile fee conditions and leading to higher drop rates and delays during peak activity.
The network mitigated the problem by rolling back the configuration change, which restored normal transaction processing. Base confirmed that overall stability has returned, though it cautioned that intermittent congestion could still result in occasional delays.
A full root-cause analysis and public postmortem are planned.
Looking ahead, Base said it will spend the next month implementing fixes aimed at preventing similar incidents. These include streamlining the transaction pipeline, reducing peer-to-peer overhead, tuning mempool queue behavior to improve transaction inclusion during congestion, and enhancing alerting and change-monitoring systems to detect issues earlier.
Base encouraged users and developers to follow further updates through its official status page as improvements are rolled out.
