Coinbase's Base Azul Upgrade Enhances Security and Transaction Speed

• •Base's Azul upgrade reduces withdrawal times from seven days to one day.
• •The upgrade features a unique multiproof security system combining TEE and zero-knowledge proofs.
• •Base can now process up to 5,000 transactions per second, enhancing overall network efficiency.

On May 13, 2026, Coinbase's Ethereum Layer 2 network, Base, launched its first independent upgrade named Azul. This upgrade introduces a multiproof security system that combines Trusted Execution Environment (TEE) and zero-knowledge proofs, significantly reducing withdrawal times from seven days to just one day. The upgrade was preceded by a testnet launch on April 21-22 and a bug bounty program worth $250,000 that concluded on May 4. The network can now handle up to 5,000 transactions per second and aims for a throughput of 1 gigagas per second. Node operators transitioned to new clients, enhancing Base's autonomy and paving the way for future upgrades. The implementation of the multiproof system addresses a major user complaint regarding withdrawal delays, while also increasing security by requiring both proof systems to validate transactions. The upgrade aligns with Ethereum’s Osaka specifications, marking a significant evolution in Layer 2 technology.
