CoinEx News: Kaspa's Toccata hard-fork track moved into its final pre-mainnet stage after a Testnet-10 rehearsal on May 18, 2026, with public status trackers showing the network past the tn10-toc2 activation score. The upgrade is targeting a June 5-20 mainnet window and adds native L1 covenant programming through Silverscript, zk-verification opcodes, covenant IDs and sequencing-commitment access, while final release notes and activation parameters remain the next confirmation step. For KAS, the catalyst shifts the trade from high-throughput payments toward a programmable-L1 narrative, with the next clean repricing trigger now moving from testnet validation to the formal mainnet activation plan.
