The web3 React dapp project gets canceled and completed and all order data from the blockchain through events and stores them in redux.
Okay, above, web3 uses antd to build the basic structure of the order component in the React dapp. We have demonstrated a basic order component. Then let’s continue and start with the environment. ganache terminal run ganache -d MetaMask Log in Then open the project and publish the contract truffle migrate –reset Then run the […]
