Base to add validity transactions in Cobalt upgrade later this month

Base is set to introduce validity transactions in its upcoming Cobalt upgrade later this month, according to Jon Roethke, a senior developer advocate at Base. Roethke said the new transaction type will support conditional execution flows onchain. He described these transactions as EIP-2930 or EIP-1559 types that execute only when specific onchain conditions are met. The update is part of the Cobalt upgrade scheduled for the end of the month. No further technical details or rollout timeline beyond that were disclosed in the brief statement.
