this function :

  web3.eth.sendTransaction({from:myaddress,to:toaddress, value:web3.toWei(1, "ether")}, function(err, transactionHash) {
  if (!err)

completely work for send ETH from ethereum-acount-address to ethereum-acount-address BUT when i set an smartcontract address for toaddress meta mask return

Transaction Error. Exception thrown in contract code.

my solidity contract is

pragma solidity ^0.4.17;

contract mysmartContract{

        function whitdrawETH() payable public {


        function getContactEthBalance() constant returns(uint) {

        return this.balance;


To make smart-contract acceptable for ether you need to implement fallback function:

function() public payable { }

Contracts that receive Ether directly (without a function call, i.e. using send or transfer) but do not define a fallback function throw an exception, sending back the Ether (this was different before Solidity v0.4.0). So if you want your contract to receive Ether, you have to implement a fallback function.

In case you want to send ether to your smart-contract mysmartContract with whitdrawETH() function you need to send methodSignature of this function to data field like this:

   from: myaddress,
   to: toaddress,
   data: web3.eth.abi.encodeFunctionSignature('whitdrawETH()')
   value: web3.toWei(1, "ether")
  • web3.eth.abi does no longer exists with MetaMask. It seems it moved elsewhere. – user2284570 Aug 15 '19 at 8:26
  • @user2284570 web3.eth.abi functions are a part of web3@1.x.x: web3js.readthedocs.io/en/v1.2.0/web3-eth-abi.html. Visibility of those functions relates to the version of the web3 library do you use in your Dapp. Metamask has nothing to do with it. – Victor Baranov Sep 8 '19 at 8:03

This is what worked for me:

receive() external payable { }

This is the function that is executed on plain Ether transfers (e.g. via .send() or .transfer()). If no such function exists, but a payable fallback function exists, the fallback function will be called on a plain Ether transfer. If neither a receive Ether nor a payable fallback function is present, the contract cannot receive Ether through regular transactions and throws an exception.
