Starknet, an Ethereum ZK‑rollup layer‑2 used for DeFi and gaming, experienced a mainnet outage of just over two hours while engineers investigate. The project previously suffered multiple 2025 disruptions — notably a September Grinta (v0.14.0) upgrade that caused ~9 hours of downtime, halted block production, two chain reorganizations and forced resubmissions — and earlier sequencer‑related multi‑hour outages. STRK token price remained steady during the incident and engineers are working to restore full functionality.
