Base activates Cobalt hard fork on mainnet

  • —Cobalt is Base's third major hard fork of 2026, following Azul and Beryl
  • —Validity and conditional transactions execute only when on-chain conditions are met
  • —TEE signer registration moved fully on-chain to speed up and tighten security
  • —Node operators had to upgrade to Base v1.4.2; Binance halted Base transfers during the window
Why it matters: Base's rapid upgrade cadence lowers operational risk and expands developer capabilities, with the next hard fork, Denim, already targeted for October 2026.
