Base completes Cobalt upgrade to enhance tokenized asset management

Base has completed its Cobalt upgrade, introducing new tools for conditional trading and issuer control for tokenized assets. The upgrade expands the B20 token standard, allowing issuers to implement compliance checks such as identity verification, accredited investor status, and sanctions screening. Issuers can now adjust share counts for corporate actions like stock splits without altering underlying balances. Additionally, the upgrade introduces 'Validity Transactions,' enabling users to set on-chain conditions for trades, such as executing swaps only if a target price is met before a specific block deadline. Base previously adopted B20 as its native standard for fungible tokens on July 8, and Coinbase issued B20 tokens representing shares of Apple, Nvidia, Meta, and Alphabet on the network on August 25.
