Base Adds a Forced Transfer Function to the Token Standard Behind Its Stock Tokens

Base, the Ethereum layer 2 run by Coinbase, has completed an upgrade called Cobalt, its third of 2026, according to reports from Cointelegraph and The Defiant. The upgrade does two distinct things: it lets traders submit transactions that sit dormant until a price or block condition is met, and it changes B20, the token standard that Coinbase's tokenized stocks are built on.

The B20 changes are the part that matters for anyone holding a share wrapped as a token. The upgrade adds tooling for compliance checks, for corporate actions such as stock splits, and for forced transfers of tokens between addresses. The Defiant describes the last of these as a seize function.

Why an issuer would want to seize a token

A tokenized equity is a claim on a real share held somewhere off chain. The registrar of that share operates under securities law, which contemplates situations where ownership must be moved without the holder's signature: a court order, a sanctions listing, a probate transfer, a demonstrated theft. Ordinary crypto tokens have no mechanism for any of that, which is one reason regulated issuers have been slow to use them.

Adding forced transfer resolves that gap and creates a different one. A token that an issuer can move out of your wallet is not bearer property in the way a bitcoin is. It is closer to a book entry at a transfer agent, with the blockchain as the book. Whether that is a feature or a defect depends entirely on whether you wanted a security or wanted self-custody, and it is a design choice the industry has been arguing about since the first regulated token standards appeared.

Conditional transactions, still on testnets

The second half of Cobalt is a new transaction type that stays idle until conditions are satisfied. A trader could submit an order now that only executes if a price reaches a level or a specific block arrives. It moves logic that normally lives in a bot or an exchange's matching engine into the chain's own transaction handling.

The Defiant notes that Base's documentation for the new transaction method lists it as running on test networks. That is a meaningful qualification: the upgrade is complete, but this particular capability is not described as live on the main network in that documentation.

The context Coinbase is building into

Coinbase has been assembling the regulated pieces around tokenized trading for months, and Base is where the tokens themselves live. The B20 compliance tooling, the corporate action handling and the seizure capability are the features a registrar asks for before it will put a real share register on a public chain. They are not features retail traders ask for.

The split in Cobalt is therefore a fair summary of where tokenized equities are heading. One half of the upgrade is for traders and makes execution more automatic. The other half is for issuers and makes ownership more reversible. Both are shipping on the same chain on the same day.
