Base, the Layer 2 solution on the Ethereum network developed by Coinbase, has launched its significant “Azul” software upgrade in the testnet environment. This update features a multiproof system and a completely overhauled client infrastructure. What sets Azul apart is that it is Base’s first independent upgrade, with integration into the mainnet scheduled for May 13.
Withdrawal times slashed with Azul
Azul unifies both hardware-based secure enclave proofs and zero-knowledge proofs under one architecture. This dual mechanism means that withdrawals can be finalized with just one of the proof types, while consensus between both methods enables users to withdraw assets from the network in as little as one day. The development team also introduced a permission system where, in some cases, zero-knowledge proofs may take precedence over secure enclave proofs.
The Base team explained, “Each type of proof can independently finalize transactions, and once they are aligned, withdrawal processes can be completed in as little as one day.”
Alongside the new multiproof framework, Azul streamlines network software operating on-chain. Legacy clients are being phased out, making “base-reth-node” the sole execution client, while a new “base-consensus” module, built on Kona, is now incorporated as a consensus client.
Performance and infrastructure upgrades
With its renewed architecture, Base targets higher throughput and steadier network performance. According to data shared by the protocol, the daily number of empty blocks has plunged by approximately 99% over the past two months—from an average of 200 per day to just two. Furthermore, the network has successfully handled transaction surges reaching as high as 5,000 transactions per second without issues.
The upgrade also brings Base closer to compatibility with Ethereum’s new Osaka execution layer standards. This allows developers to adapt to the changes without drastically modifying application code.
The Base team emphasized that most on-chain applications will not require any alterations. However, node operators and developers relying on specialized functions are advised to prepare for the upgrade.
Security contest and market position
Ahead of the mainnet launch, a security contest was initiated on the Immunefi bug bounty platform, running until May 4. The contest aims to identify critical vulnerabilities, with a total reward pool of $250,000 for those who discover significant bugs in the software.
Base’s influence within the ecosystem continues to grow. Fresh data from sources such as The Block and DefiLlama indicate that the network now hosts approximately $4.98 billion in stablecoin market capitalization and $4.4 billion in total value locked in decentralized finance (DeFi). Base also leads all Optimistic Rollup solutions in terms of active addresses.
Looking ahead, the network is set to gain more upgrades in the coming months, focusing on enhanced performance and an improved user experience. Plans are underway for faster transaction processing by late June and the rollout of user-facing features—including account abstraction—by late August.
