Base Cobalt Upgrade Adds Conditional Transactions and Changes to B20 Token Standard

Base releases Cobalt upgrade

Base, an Ethereum layer-2 network, has shipped an upgrade called Cobalt, its third upgrade of the year. The upgrade lets traders submit transactions that stay dormant until price or block conditions are met.

The upgrade also makes three changes to the B20 token standard, which is the standard behind Coinbase's tokenized stocks.

Key facts from the report

  • Cobalt is the year's third Base upgrade.
  • Conditional transactions remain inactive until certain price or block conditions are met.
  • The upgrade includes three changes to the B20 token standard used by Coinbase's tokenized stocks.
  • The new transaction method is listed in Base's documentation as running on test networks.

What The Defiant reports

The Defiant reports these details about Cobalt. The article does not include an official statement from Base.

What is still unclear

The article does not describe the three B20 token standard changes. It also does not explain the "seize function" mentioned in the headline.

The article does not say whether the new transaction method is also live on Base's mainnet.
