Create your Fungible Token (ERC-20)
MetaMask, a widely adopted Ethereum wallet, enables users to manage their Ether and ERC-20 tokens while providing a convenient interface for interacting with decentralized applications (dApps) and smart contracts. With the increasing significance of fungible tokens in the digital asset landscape, MetaMask offers a simple and accessible way to create your own ERC-20 token contract, opening the door to numerous possibilities and benefits.
Why create an ERC-20 token contract?
Fungible tokens like ERC-20 tokens are digital assets that can be exchanged on a one-to-one basis, making them an ideal choice for various applications, such as:
- Creating a digital currency for your project or platform
- Launching an initial coin offering (ICO) or token sale event
- Developing a reward or loyalty program for your business
- Establishing a decentralized governance system for your community
Hint
MetaMask is designed as a browser extension to provide a user-friendly interface and secure key management for interacting with dApps and web services. Connecting from Node.js is not supported because MetaMask focuses on end-user interactions within web browsers, while Node.js is a server-side JavaScript runtime typically used for backend development.
How to create your Fungible token with MetaMask from your browser-based application
Use the TatumSDK (@tatumio/tatum
) to prepare, sign and broadcast the transaction using MetaMask.
You will leverage the WalletProvider submodule, which includes multiple browser-based wallet extensions. MetaMask is just one of them.
// Install with: npm install @tatumio/tatum
const { TatumSDK, Network, MetaMask } = require("@tatumio/tatum");
(async () => {
try {
const tatum = await TatumSDK.init({ network: Network.ETHEREUM });
// We have prepared a deploy transaction of ERC-20 contract from your default connected MetaMask account to the recipient
// Result is a transaction IF of a broadcasted transaction
const txId = await tatum.walletProvider.use(MetaMask).createFungibleToken({
name: 'Your Token Name',
symbol: 'Your Token Symbol',
decimals: 18,
initialSupply: 1_000_000})
console.log(txId);
// Once the transaction is included in a block, you can get the contract address of the newly created collection
const contractAddress: string | null = await tatum.rpc.getContractAddress(txId)
console.log(contractAddress)
} catch (error) {
console.error("Error signing a transaction using MetaMask:", error);
}
})();
// yarn add @tatumio/tatum
import {TatumSDK, Network, Ethereum, MetaMask} from '@tatumio/tatum'
const tatum = await TatumSDK.init<Ethereum>({network: Network.ETHEREUM})
// We have prepared a deploy transaction of ERC-20 contract from your default connected MetaMask account to the recipient
// Result is a transaction IF of a broadcasted transaction
const txId: string = await tatum.walletProvider.use(MetaMask).createFungibleToken({
name: 'Your Token Name',
symbol: 'Your Token Symbol',
decimals: 18,
initialSupply: 1_000_000})
console.log(txId)
// Once the transaction is included in a block, you can get the contract address of the newly created collection
const contractAddress: string | null = await tatum.rpc.getContractAddress(txId)
console.log(contractAddress)
