Base said recent transaction delays and dropped transactions were caused by a configuration change that has now been rolled back and fixed.
The issue surfaced over the weekend when users experienced slow or missing transaction confirmations, even though blocks continued to be produced and the network did not suffer a full outage.
“We mitigated the issue by rolling back the change and have validated that network stability has been restored,”
Base said in a post on X.
Base explained that the configuration change affected transaction propagation, causing the block builder to repeatedly fetch transactions that could not be executed as base fees rose rapidly.
The team said it is now rolling out longer-term infrastructure upgrades aimed at preventing similar incidents, including optimising the transaction pipeline, tuning mempool handling and strengthening monitoring during rollouts.
The upgrade work is expected to take about a month and comes as Base leads Ethereum layer-2 networks by total value locked, with about $4.2 billion, or nearly 48% of the market, according to DefiLlama.
Base has become central to Coinbase’s broader strategy to expand beyond trading into payments, stablecoins and onchain financial services built on always-on infrastructure.
At the time of reporting, Ethereum price was $2,094.17.
