I'm trying to send some Ether to the payable function of my contract and I'm unable to find/understand a resource to do so.

Here's my attempt below:

Web3 App file (simplified, without initialisation functions) :

App = {
  sendEther: function(_value) {

    // Enter details to send transaction;
    web3.eth.getAccounts(function(error, accounts) {
      if (error) {

      var account = accounts[1]; // send from account index 1

      App.contracts.Plant.deployed().then(function(instance) {

        return instance.sendTransaction({ // Something like this?!
          from: account,
          gas: 5000,
          value: _value
      }).then(function(result) {
        return App.UpdateContractValues();
      }).catch(function(err) {

Simplified smart contract:

contract Plant {

    address public creator;

    uint public finney_balance; 

    function () payable public {
        finney_balance += msg.value/1000000000000000;
        depositedFunds(msg.value, finney_balance);
  • What error/s are you getting with the code above? Nov 24, 2017 at 13:02
  • plantInstance.sendTransaction is not a function which is expected as I wrote it as a placeholder.

If you are using truffle you can do it exactly as you wrote above:

  from: account,
  gas: _gas,
  value: _value
}).then(function(result) {

Here's the truffle reference: https://github.com/trufflesuite/truffle-contract#sending-ether--triggering-the-fallback-function

  • Does this work for payable function? Where do you mention what function is being called? Mar 6, 2018 at 16:39
