Free / public RPC URLs
Public RPC URLs for Base
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.
