eRPC is a fault-tolerant EVM RPC proxy and permanent caching solution. It is built with read-heavy use-cases in mind such as data indexing and high-load frontend usage.

Getting Started

With this eRPC template, get immediate access to 2,000+ chains and 4,000+ public free EVM RPC endpoints.

1. Deploy this template

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

curl 'https://erpc.up.railway.app/evm/42161' \
--header 'Content-Type: application/json' \
--data '{
    "method": "eth_getBlockByNumber",
    "params": [
        "latest",
        false
    ],
    "id": 9199,
    "jsonrpc": "2.0"
}'

3. Access Grafana

Find Grafana endpoint here:

and login with the following credentials:

• username: admin
• password: admin

4. Monitor metrics

Send more requests and watch the metrics being collected and visualized in Grafana.

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 which is a combination of Chainlist, ChainID.Network, and Viem public RPC endpoints.

Next steps

This setup is recommended for development and testing purposes. For production environments, we recommend extending eRPC config with dedicated premium providers and advanced failover configs.
