Juno is a Go implementation of a Starknet full-node client created by Nethermind to allow node operators to easily and reliably support the network and advance its decentralisation goals. Juno supports various node setups, from casual to production-grade indexers.

  • 💿 Small database footprint: Approximately 182GB on mainnet.
  • ⚡ Ultra-fast synchronisation: Limited only by your hardware and the sequencer.
  • 💯 Complete JSON-RPC spec compliance: Everything Starknet, accessible from a single point.
  • 🔎 Minimal RPC response latency: Ensuring your applications run smoothly.
