Understanding MetaMask Providers: A Guide to Ethereum Smart Contracts
MetaMask is a popular digital wallet for Ethereum that allows users to store, send, and receive Ether (ETH) and other ERC-20 tokens. One of the key features of MetaMask is its ability to connect to multiple service providers, allowing users to run decentralized applications (dApps), interact with smart contracts, and transfer assets directly in the browser.
What are MetaMask providers?
