ERC-20 tokens, which represent interchangeable assets on blockchains, are crucial for transactions on Ethereum-compatible networks, and this tutorial guides users through creating one on Polygon, a layer-2 EVM blockchain. Polygon, the focus of this guide, offers faster and cheaper transactions compared to Ethereum and is expanding beyond the Polygon PoS chain into a broader protocol for Ethereum-compatible networks. The tutorial outlines steps to create and deploy an ERC-20 token using tools like Remix IDE, Brave Wallet, and OpenZeppelin on the Polygon Mumbai test network. Users can bridge assets from Ethereum to Polygon using the Polygon Bridge and leverage Polygon's lower gas fees and higher transaction speeds. The guide emphasizes the flexibility provided by Solidity, allowing tokens to be deployed on any EVM-compatible blockchain and suggests further enhancements such as additional functionalities or integration with DeFi protocols.
