Base Launches Cobalt Upgrade Adding Trading And Token Issuer Tools
Image: Bitcoin.com NewsBase, the Coinbase-backed Ethereum Layer 2 network, launched its third mainnet Cobalt upgrade in late September 2026. The upgrade adds Validity Transactions that let users submit time-bound, condition-based trades that stay dormant until preset terms are met and remain private until onchain inclusion. It also expands the B20 token standard with new compliance and issuer management features for tokenized assets, aligning with Base's shift to prioritize financial tool development.
