BASE LAUNCHES COBALT UPGRADE WITH CONDITIONAL TRANSACTIONS

Summary from the TLDR Crypto newsletter

Base's third mainnet upgrade, Cobalt, went live with Validity Transactions that let traders submit time-bound transactions that stay dormant until set conditions are met, such as a swap that only activates if a pool price crosses a threshold before a given block. The upgrade also adds Composite Policies to its B20 token standard, letting issuers combine KYC allowlists and sanctions blocklists with OR/AND logic without duplicating member lists, Schedule Multiplier Updates for things like stock splits, and a "seizeWithMemo" function that lets authorized administrators reassign frozen balances with an onchain record. Base also said it plans to cut block times from 2 seconds to 200 milliseconds and make smart accounts native at the protocol level in coming months.
