The biggest market development was a broad altcoin rally, led by Moonriver, OTC, and Orbio.so. Moonriver rose 85.40% after its Base migration and late-claims window closed on 30 September 2026. The move spread across several ecosystems rather than staying concentrated in one chain. Solana, BNB, Hyperliquid, and Cardano-linked assets all traded higher, pointing to a broad risk-on rotation.
