Base launches Cobalt upgrade with conditional transactions and new B20 asset functions
- —Validity Transactions let users submit time-bound transactions that stay dormant until conditions are met
- —Composite Policies combine KYC allowlists and sanctions blocklists using OR/AND logic without offchain sync
- —seizeWithMemo allows authorized admins to reassign balances of frozen accounts with an onchain memo
- —Base plans to reduce block times from 2 seconds to 200ms and make smart accounts native
Why it matters: The upgrade expands tooling for traders and tokenized-asset issuers, sharpening L2 competition for institutional capital.
