Base Fixes Transaction Delays After Config Error, Maintains L2 Lead

Coinbase’s Ethereum layer-2 network Base said recent slow or missing transactions were caused by a configuration error that has been fixed.

Over the weekend, Base users experienced elevated transaction drops and delays in getting transactions included onchain. Despite the slowdown, blocks continued to be produced and the network remained operational, suggesting that the incident didn’t cause a full outage.

In a Wednesday post on X, Base explained that a change to transaction propagation led the block builder to repeatedly fetch transactions that could not be executed as base fees climbed quickly.

“We mitigated the issue by rolling back the change and have validated that network stability has been restored,” it said.

Base plans upgrade to prevent future delays

The team also announced that they are now working on longer-term fixes to prevent similar disruptions.

Planned improvements include streamlining the transaction pipeline, reducing unnecessary overhead, tuning how the mempool queue handles pending transactions and strengthening monitoring during infrastructure rollouts. The work is expected to take about a month.

Base has emerged as the leader among Ethereum layer-2 networks by total value locked (TVL). It held about $4.2 billion in TVL, accounting for 47.6% of Ethereum L2 share on Wednesday, according to data from DefiLlama.

Arbitrum (ARB) now controls 27% of the layer-2 market, ranking it a distant second behind Base, while all other networks remain limited to single-digit shares.
