Create your own token with TypeScript

Create ERC-20 tokens that can be used as your own currency with the thirdweb TypeScript SDK.


You can deploy a Token via the dashboard, but in this guide, we'll demonstrate how to do it using TypeScript!

Create a new folder on your computer called my-token, and within this folder, create a file called mint-token.ts.

Installing TypeScript SDK

Install the required dependencies to get started with thirdweb, by running the following command inside your my-token folder.:

npm install @thirdweb-dev/sdk dotenv

Deploying a Token Contract

To deploy a Token using the SDK, we can make use of the sdk.deployer, which can create any of thirdweb's pre-built contracts!

To deploy from your wallet, you'll first need to export your wallet's private key and add it to an environment variable in this project.

How to export your private key

Learn how to export your private key from your wallet.

To do this, create a file called .env in the same folder as your mint-token.ts file, and add the following to it:


Ensure you store and access your private key securely.

  • Never commit any file that may contain your private key to your source control.

Now we're ready to deploy the Token!

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

async function main() {
const NETWORK = "mumbai";
const sdk = ThirdwebSDK.fromPrivateKey(
process.env.PRIVATE_KEY as string,

const deployedAddress = await sdk.deployer.deployToken({
name: "My Token",
primary_sale_recipient: "0x-your-public-wallet-address-here",

// Add the next code snippet here


Before we run this script, let's add some code to some tokens immediately after we create the smart contract!

Minting Tokens

To mint tokens, we:

  • Get the token contract using its contract address
  • Call the mintTo function with our address and desired quantity

Be sure to replace the primary_sale_recipient and toAddress with a valid wallet address.

const tokenContract = sdk.getToken(deployedAddress);

const toAddress = "0x-your-public-wallet-address-here"; // Address of the wallet you want to mint the tokens to
const amount = "1.5"; // The amount of this token you want to mint

const transaction = await tokenContract.mintTo(toAddress, amount);


To run the script, run:

npx ts-node mint-token.ts

That's it!

Congratulations! You have created your own ERC-20 token!
