Coinbase's Ethereum Layer 2, Base, is set to activate its Azul upgrade on mainnet, introducing a multiproof system and faster withdrawals.

Base, the Ethereum layer 2 (L2) network developed by Coinbase, is targeting a mainnet activation on May 13 for its first independently built network upgrade, dubbed Azul [1]. This upgrade is described as a significant step toward achieving Stage 2 decentralization, the highest trust-minimization standard for Ethereum L2s [1].

**Key takeaways**
* The Azul upgrade, set for mainnet activation on May 13, is Base's first independent network upgrade [1, 3].
* Azul introduces a multiproof system combining trusted execution environment (TEE) and zero-knowledge (ZK) provers for enhanced security [1, 2].
* This new system aims to reduce withdrawal times from Base to Ethereum to as little as one day when both provers agree [1, 2].
* The upgrade streamlines Base's client stack and aligns the network with Ethereum's latest execution-layer specifications [1, 2].
* Base currently ranks as the second-largest L2 by total value secured, with $12.12 billion [1].

## Advancing Security and Performance
The core of the Azul upgrade is a multiproof system that integrates two independent proof mechanisms: a trusted execution environment (TEE) prover and a zero-knowledge (ZK) prover [1]. Both provers can independently finalize transactions, and when both agree, withdrawals from Base to Ethereum could settle in as little as one day [1]. This architecture is designed to detect and handle proof system failures entirely on-chain, a key requirement for Stage 2 decentralization [1]. The design is modeled on Ethereum co-founder Vitalik Buterin's L2 finalization roadmap [1].

Beyond security, Azul aims to streamline Base's underlying client stack and align the network with Ethereum's latest execution-layer specifications [1]. This includes consolidating Base onto a single execution client, base-reth-node, and a new consensus client based on OP Kona, known as base-consensus [2]. This shift is intended to simplify operations, improve historical sync speeds, and accelerate the rollout of performance upgrades [2]. The upgrade also integrates Ethereum's Osaka execution-layer features, such as a per-transaction gas cap and adjustments to precompile costs [2]. Base has also launched a $250,000 bug bounty competition for Azul, running through May 4 [1].

## Why it matters
The Azul upgrade represents a turning point for Base as it marks the first upgrade built entirely on Base's own streamlined stack, moving away from reliance on the broader OP Stack [2]. This independence allows Base to implement updates at its own pace [2]. Faster withdrawal times, potentially reduced to one day, could significantly improve user experience by reducing friction for moving assets and stablecoins across the Ethereum ecosystem [2]. This aligns with broader industry calls for better user experience in scaling solutions [2]. Base, which currently holds the position of the second-largest L2 by total value secured with $12.12 billion, aims to enhance its competitiveness in the L2 landscape through these advancements [1, 2]. The network has also focused on stablecoins, global markets, and AI agents as key growth areas, with faster and cheaper finality being foundational to these initiatives [1].
