Railway installation

Railway (opens in a new tab) provides a quick and easy way to deploy eRPC. To get started, please ensure that you have signed up or logged in to Railway and connected your GitHub account.

Deploy

Click the Deploy on Railway button below to get started. This will take you to our eRPC template, which includes proxy and monitoring services.

(opens in a new tab)

This template comes with a default erpc.yaml configuration that will give you access to 2,000+ chains and 4,000+ public free EVM RPC endpoints.

Config customizaiton

If you need further customization, you can fork the template's repository (opens in a new tab). E.g. you can create an erpc.yaml file in your forked repository to add your own premium RPC endpoints, caching, customised network or upstream level failsafe configs, etc.

After forking and adjustments, you can either connect your forked repository to your existing deployment or create a new service linked to this forked repository.

Usage in your services

If your backend services (like indexers or MEV bots) are on the same Railway project as eRPC, you can reduce cost and overhead by using private networking (.railway.internal) to connect:

const result = await fetch("https://my-erpc.railway.internal/main/evm/1", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    method: "eth_getBlockByNumber",
    params: ["0x1203319", false],
    id: 9199,
    jsonrpc: "2.0",
  }),
});

If you need external access or your services are hosted elsewhere, use the public URL found under Settings > Networking > Public Networking in your eRPC service:

Monitoring

After sending more requests, click on monitoring service and find your Grafana url under Settings > Networking > Public Networking

You can login with the following credentials:

username: admin
password: admin

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