Base Fixes Transaction Delays After Config Error, Preserves L2 Lead
Base, Coinbase’s Ethereum layer-2 network, faced a weekend slowdown caused by a configuration error in a recent transaction-propagation change. While users reported elevated drops and longer waits for on-chain inclusion, blocks continued to be produced and the network did not experience a full outage. In a Wednesday post on X, Base explained that the modification to how transactions were propagated caused the block builder to repeatedly fetch transactions that could not be executed as base fees rose rapidly. The team rolled back the change and said stability has been restored, while outlining plans for longer-term fixes to harden the system against similar hiccups.
Key takeaways
- The incident stemmed from a propagation-change that triggered repeated fetches of non-executable transactions as base fees climbed, prompting a rollback to restore stability.
- Despite the hiccup, the network remained operational and continued producing blocks, indicating resilience even as throughput slowed.
- Longer-term fixes are targeted at the transaction pipeline, overhead reduction, mempool handling, and enhanced rollout monitoring, with an estimated one-month timeline.
- Base is the leading Ethereum layer-2 by TVL, holding about $4.2 billion and roughly 47.6% of the Ethereum L2 market, according to DefiLlama data on a recent Wednesday.
- Arbitrum (CRYPTO: ARB) sits in second place with about 27% of the L2 market, while other networks remain in single-digit shares.
- The episode underscores Base’s central role in Coinbase’s broader “super-app” strategy, integrating stablecoins and on-chain utilities into an expanding suite of products beyond traditional trading.

Market context: The episode highlights ongoing scaling tensions in the Ethereum ecosystem as users migrate activity to layer-2 solutions. Base’s ascent to a majority share of Ethereum L2 TVL underscores the significance of reliability as decentralized finance, payments, and other on-chain use cases increasingly rely on L2 infrastructure. The incident comes amid a landscape where TVL concentration among leading L2s remains pronounced, making resilience and governance in rollout processes particularly important for market participants.
Why it matters
The event is a reminder that even the most sophisticated scaling stacks face operational risk as they push higher throughput and lower fees for users. For Base, the stakes are heightened by Coinbase’s strategy to turn the network into the backbone of an “everything exchange”—a platform that blends crypto trading with stocks, prediction markets and other financial services. By positioning Base as the on-chain distribution layer for Coinbase’s broader product suite, the company aims to accelerate adoption and embed on-chain rails across multiple product lines.
From a technical perspective, the rollback demonstrates a fast-response mechanism in practice: a rollback to a safe configuration, followed by a commitment to strengthen the pipeline and monitoring. The plan to streamline the transaction pipeline, trim unnecessary overhead, optimize the mempool’s handling of pending transactions, and bolster monitoring during infrastructure rollouts indicates a shift from quick patch fixes toward more foundational resilience. The time horizon—a little over a month—reflects the emphasis on both rapid stabilization and longer-term reliability enhancements.
Market researchers and on-chain developers will be watching how these improvements translate into real-world throughput and user experience. Base’s leadership in TVL among Ethereum L2s—reported at about $4.2 billion and a 47.6% share on one recent update—highlights the impact of operational reliability on capital allocation across competing networks. Arbitrum trails at roughly 27% of the L2 market, illustrating a competitive dynamic where even small improvements in efficiency or uptime can influence flow and engagement on L2 ecosystems. The broader implication is that reliability, governance, and measurable performance gains become critical differentiators as users evaluate where to deploy capital and where to build new applications.
Crucially, the incident sits within Coinbase’s broader strategic framework. By strengthening Base and expanding its use cases—from stablecoins to real-world financial utilities—the company signals a long-term commitment to on-chain infrastructure as a foundation for diverse products. This approach is consistent with the trend of crypto platforms seeking to commoditize on-chain rails, enabling a wider array of services that extend beyond custody and trading. As the ecosystem evolves, the emphasis on robust, observable performance will be a key factor shaping developer and user confidence in Layer-2 networks as scalable, secure conduits for everyday financial activity.
What to watch next
- Progress of the one-month improvement window: updates on the rollout, new monitoring dashboards, and any interim performance metrics.
- Any subsequent status notices from Base on X or through official channels detailing stability metrics or new incidents.
- Changes to the transaction pipeline and mempool handling, including benchmarks on throughput and latency during peak periods.
- Definitive commentary from Coinbase and Base leadership about how the improvements may influence adoption of the “everything exchange” concept.

Base’s scaling hiccup and the road ahead
Base sits atop Ethereum (CRYPTO: ETH), and its rapid ascent as the leading Ethereum layer-2 has reframed how developers and users think about scaling, gas efficiency, and on-chain usability. In the latest episode, a propagation-change misstep briefly disrupted everyday activity, renewing focus on the fragility that can accompany swift deployments. The network’s ability to continue producing blocks, even as a backlog of transactions faced difficulty entering the mempool, underscored resilience—yet also exposed the delicate balance between speed and reliability that underpins Layer-2 ecosystems.
In a Wednesday update on X, Base explained that the root cause lay in how transaction propagation was implemented during a previous change. As base fees climbed, the block builder repeatedly fetched transactions that could not be executed, creating artificial pressure and delays. The corrective move—rolling back the change—appeared to restore stable operation, and engineers signaled that the episode had highlighted gaps to address in the near term. The planned fixes emphasize a broader redesign: a more streamlined transaction pipeline, reduced overhead, refined mempool logic, and heightened vigilance during infrastructure rollouts. The goal is not only to restore performance but to prevent recurrence as activity continues to migrate toward Layer-2 solutions.
Techniques for measuring and maintaining throughput will be central as Base competes for dominance with other major Layer-2 networks. Arbitrum, for example, remains a formidable contender with a substantial share of the market, illustrating that users and developers weigh reliability, cost, and developer experience as they allocate liquidity across L2s. The competitive dynamic among networks—Base’s dominant position versus Arbitrum’s strong footing—suggests that even incremental improvements to uptime or transaction latency can yield meaningful shifts in on-chain activity and liquidity flows.
Beyond the technical fixes, Base’s role within Coinbase’s strategic framework is increasingly clear. The company has signaled a push toward an “everything exchange” model, a platform that blends crypto trading with traditional financial products and services. Stablecoins and on-chain payments are part of this vision, but the network’s future hinges on how seamlessly it can scale, support diverse product features, and maintain a high level of reliability for users and developers alike. As Base expands, it becomes a pillar in Coinbase’s broader ambition to normalize on-chain interactions across everyday financial use cases, reinforcing the importance of robust Layer-2 infrastructure in a rapidly evolving crypto landscape.
