L1 (Layer 1 Blockchain)

Three stablecoin-issuer-built L1 networks are launching in 2026: Circle’s Arc (enterprise-grade, PPSI-compliant settlement), Stripe/Bridge’s Tempo (payments-optimized, Bridge stablecoin infrastructure), and Tether’s Plasma (UTXO-based, Tether-native). Alongside these, Hyperliquid’s L1 operates with $4.85B stablecoin market cap and 93% USDC dominance, making it a critical stablecoin infrastructure chain despite originating as a derivatives platform.
