You can send a transaction in Sender using the eth_sendTransaction RPC method.
For example, the following JavaScript gets the user's accounts and sends a transaction when they select each button, and the following HTML displays the buttons.
constethereumButton=document.querySelector('.enableEthereumButton');constsendEthButton=document.querySelector('.sendEthButton');let accounts = [];// Send Ethereum to an addresssendEthButton.addEventListener('click', () => {sender.ethereum.request({ method:'eth_sendTransaction', params: [ { from: accounts[0],// The user's active address. to:'0x2f318C334780961FB129D2a6c30D0763d9a5C970',// Required except during contract publications. value:'0x29a2241af62c0000',// Only required to send ether to the recipient from the initiating external account. gasPrice:'0x09184e72a000',// Customizable by the user during MetaMask confirmation. gas:'0x2710',// Customizable by the user during MetaMask confirmation. }, ], }).then((txHash) =>console.log(txHash)).catch((error) =>console.error(error));});ethereumButton.addEventListener('click', () => {getAccount();});asyncfunctiongetAccount() { accounts =awaitsender.ethereum.request({ method:'eth_requestAccounts' });}
