Free / public RPC URLs

Public RPC URLs for Avalanche C-Chain

These endpoints are free, anonymous, and rate limited. They are useful for development, wallet reads, and one off scripts. For production traffic or indexer workloads, pair them with a paid provider so the public list becomes your fallback rather than your primary.

Caveats and things to verify

  • Avalanche has three chains: X (UTXO assets), P (platform), and C (EVM). Only the C-Chain is EVM compatible and used by typical dapps.
  • Subnets and L1s on Avalanche have their own chain IDs. The C-Chain ID 43114 is not interchangeable.
