How Can We Help?
The Infura API Key is used to communicate with the Ethereum blockchain. It is used in the Ethereum ICO WordPress Plugin, the Cryptocurrency WordPress Plugin for WooCommerce, the WordPress Ethereum Wallet plugin and in the Ether and ERC20 tokens WooCommerce Payment Gateway. Infura API ID supports Sepolia, Görli, Ropsten, Rinkeby and Kovan Ethereum testnets.
Step 1. Register
