​
Prerequisites

  • An Alchemy account (sign up free)
  • Basic familiarity with EVM RPC endpoints

​
Steps

1

Create an app

From the Alchemy dashboard, create a new app and select Injective as the chain. Choose the network:
  • Injective EVM Mainnet: Chain ID 1776
  • Injective EVM Testnet: Chain ID 1439
2

Copy your RPC endpoints

Open your app and copy the HTTPS and WebSocket endpoints:
https://inj-mainnet.g.alchemy.com/v2/<YOUR_API_KEY>
wss://inj-mainnet.g.alchemy.com/v2/<YOUR_API_KEY>
Keep your API key private, treat it like a password.
3

Start building

Use the endpoint with your preferred library:
import { JsonRpcProvider } from "ethers";

const provider = new JsonRpcProvider(
  "https://inj-mainnet.g.alchemy.com/v2/<YOUR_API_KEY>"
);

const blockNumber = await provider.getBlockNumber();
console.log("Latest block:", blockNumber);
