Create your Fungible Token
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.
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
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.
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.
