Send Ether Transaction
If you have replaced your web3 provider with Fortmatic provider, nothing needs to be changed for web3 send Ether transactions to continue working.
The Fortmatic X modal will pop open and ask users to confirm their transaction once this web3 function is called on the client-side.

// Initialize provider
import Fortmatic from 'fortmatic';
import Web3 from 'web3';
const fm = new Fortmatic('YOUR_API_KEY');
window.web3 = new Web3(fm.getProvider());
const toAddress = '0xb159752065EA68Ef0B22249Df25864E624fec45D';
const sendValue = web3.toWei(1, 'ether'); // Convert 1 ether to wei
// Get user account wallet address first
web3.eth.getAccounts((error, accounts) => {
if (error) throw error;
// Construct Ether transaction params
const txnParams = {
from: accounts[0],
to: toAddress,
value: sendValue
}
// Send Ether transaction with web3
web3.eth.sendTransaction(txnParams, (error, txnHash) => {

Fortmatic provides the option to offer a customized gas price. If provided, it will be shown as a suggested option in the delivery fee section. One parameter addition to include a customized gas price should suffice. Gas limit is optional, if not provided, Fortmatic will smartly estimate the gas limit for the transaction!
const txnParams = {
from: accounts[0],
to: toAddress,
value: sendValue,
gasPrice: '0x2540be400', // Include your own gas price here.
}
