Getting Started

No SDK install required for API/cURL. Call the HTTP endpoints directly. Keep your secret key server-side; use client IDs in frontends.

Initialize the SDK and contract on your project:

import { createThirdwebClient, getContract } from "thirdweb";
import { defineChain } from "thirdweb/chains";

// create the client with your clientId, or secretKey if in a server environment
const client = createThirdwebClient({
  clientId: "YOUR_CLIENT_ID"
 });

// connect to your contract
const contract = getContract({
  client,
  chain: defineChain(137),
  address: "0x12d55be6A91C36F087666775B5C3C432CD2a94bF"
});

You will need to pass a client ID/secret key to use thirdweb's infrastructure services. If you don't have any API keys yet you can create one by creating a project for free from the dashboard.
