Coinbase's Base Azul Goes Live on Mainnet with ZK Proofs and 24-Hour Withdrawals

Coinbase has deployed Base Azul , an enhanced version of its Layer 2 (L2) network Base , on the mainnet on May 29, 2026. This update introduces zero-knowledge proofs (ZK proofs) , optimized native clients , and technical improvements under the codename Osaka . Major innovations include the ability to process up to 5,000 transactions per second (TPS) in bursts , compared to around 100 TPS for the original version of Base. The primary goal is to enable withdrawals in 24 hours , a groundbreaking feature for an Ethereum L2, to attract institutional actors and liquidity-demanding traders. What Happened Base Azul is now operational on the mainnet since May 29, 2026. Key developments include the native integration of ZK proofs , which improve both scalability and transaction privacy . The native clients , such as wallets or decentralized applications (dApps), have been redesigned for faster interactions with the network. The Osaka updates also bring optimizations to the sequencer and ZK prover , reducing gas costs for users. No data has yet been published regarding the Total Value Locked (TVL) or transaction volume generated by Base Azul. Why It’s Important The ZK proofs allow transactions to be validated without exposing underlying data, which is particularly advantageous for L2s like Base. They reduce the load on Ethereum by aggregating multiple transactions into a single proof while maintaining a high level of decentralization. The capability of 5,000 TPS in bursts positions Base Azul as a serious competitor to centralized networks like Solana or Visa, while retaining Ethereum’s blockchain advantages. The 24-hour withdrawals represent a major advancement for institutional users, who seek fast liquidity and controlled costs. On a sectoral level, this innovation could accelerate the race for high-performance L2s , prompting actors like Arbitrum, Optimism, or zkSync to strengthen their own solutions. Decentralized exchanges (DEXs) and DeFi protocols could benefit from increased liquidity and an optimized user experience . On a broader scale, if Base Azul succeeds in attracting financial institutions , it could reduce reliance on centralized networks and promote the adoption of tokenized assets on Ethereum. However, L2 competition remains intense, and regulations , particularly in the U.S., could influence this dynamic. What to Watch The TVL of Base Azul within 30 days: a figure exceeding $500 million would be a strong adoption indicator. The number of dApps deployed on Base Azul by July 2026: significant growth would signal an expanding ecosystem. The reactions from other L2s : if Arbitrum or Optimism announce similar updates, it could trigger a performance race. The impact on ETH price and Base’s market share relative to its competitors. The regulatory decisions that may influence institutional adoption of L2s.
