Base network activates the Cobalt upgrade, expanding the B20 standard to support multiple compliance checks including identity verification and sanction screening, and launches conditional execution functionality for valid transactions.
Base announced that Cobalt will launch in September, with key features including Sponsorship, Batch Calls, and Session Keys. Among these, Sponsorship allows applications to sponsor transaction fees for users, enabling free Gas; Batch Calls supports bundling multiple transactions into one, reducing operational steps; Session Keys allow users to authorize applications to sign transactions on their behalf within a specific scope, reducing repeated authorizations.
