Free & Public RPC Endpoints

Get immediate access to 2,000+ chains and 4,000+ public free EVM RPC endpoints:

1. Run an eRPC instance:

npx start-erpc

You can also deploy it to Railway:

(opens in a new tab)

2. Send requests to the eRPC instance based on chainId:

curl 'http://localhost:4000/evm/42161' \
--header 'Content-Type: application/json' \
--data '{
    "method": "eth_getBlockByNumber",
    "params": [
        "latest",
        false
    ],
    "id": 9199,
    "jsonrpc": "2.0"
}'

3. 🚀 Profit!

How it works?

When running eRPC without a configuration file, it will use a basic configuration using the special repository provider.

This provider automatically fetches (every 1 hour) RPC public endpoints from https://evm-public-endpoints.erpc.cloud (opens in a new tab) which is a combination of Chainlist (opens in a new tab), ChainID.Network (opens in a new tab), and Viem (opens in a new tab) public RPC endpoints.

Next steps

This setup is recommended for development and testing purposes. For production environments, we recommend extending eRPC config (opens in a new tab) with dedicated premium providers and advanced failover configs.
