All transactions made with this instance of the SDK will be signed using the private key.

const sdk = ThirdwebSDK.fromPrivateKey(process.env.PRIVATE_KEY, "ethereum");

Configuration​

privateKey​

The private key of the wallet you want to use to initiate transactions with.

Sensitive Value

Losing or leaking your private key will result in the loss of your funds.

Please proceed carefully, and consider using a secret manager instead.

import { ThirdwebSDK } from "@thirdweb-dev/sdk";

const sdk = ThirdwebSDK.fromPrivateKey(
  "your-private-key-here", // DANGER: This is a sensitive value that should be stored securely.
  "ethereum",
);

chain​

import { ThirdwebSDK } from "@thirdweb-dev/sdk";

const sdk = ThirdwebSDK.fromPrivateKey(
  process.env.PRIVATE_KEY, // DANGER: This is a sensitive value that should be stored securely.
  "ethereum", // Can be a string, a Chain object from @thirdweb-dev/chains, or a custom chain.
);
