Base Completes Cobalt Mainnet Upgrade, Introducing Conditional Transactions

Base has successfully completed its third mainnet upgrade, Cobalt, which introduces the 'Validity Transactions' feature. This allows users to submit transactions with specific conditions that must be met for on-chain execution; otherwise, the transactions remain excluded. The upgrade also enhances the B20 token standard with Composite Policies for flexible whitelist/blacklist management and a Schedule Multiplier aligned with ERC-8056 for features like stock splits. Looking ahead, Base plans to reduce block times to 200 milliseconds, implement native smart accounts, and integrate further EVM improvements.
