I have a Smart contract (SC1):
pragma solidity ^0.5.8;
contract MySC1 {
address owner;
constructor() public {
owner = msg.sender;
}
function sendTo(address payable receiver, uint amount) public {
receiver.transfer(amount);
}
function() external payable{
}
}
I am transferring it Ether from account2 but when I check the balance it is still zero:
$ truffle exec ts4.js
Using network 'development'.
acc2 balance 100000000000000000000 address 0xEa719Cf8f777350c0D0B0be8cc4A90Aa95f36898
SC1 deployed 0x43ba105f5DeC27B9c4183c95971672e53EaA9a64
SC2 deployed 0xc80c3fDE077Ce7360e738BB6525A92bf7953ea51
Initial SC1: 0x43ba105f5DeC27B9c4183c95971672e53EaA9a64 balance is 0
Initial SC2: 0xc80c3fDE077Ce7360e738BB6525A92bf7953ea51 balance is 0
11 Ether from 0xEa719Cf8f777350c0D0B0be8cc4A90Aa95f36898, sc1: 0x43ba105f5DeC27B9c4183c95971672e53EaA9a64 balance is 0
but when I execute the script again, it shows me the correct balance:
$ truffle exec ts4.js
Using network 'development'.
acc2 balance 88999579200000000000 address 0xEa719Cf8f777350c0D0B0be8cc4A90Aa95f36898
SC1 deployed 0x43ba105f5DeC27B9c4183c95971672e53EaA9a64
SC2 deployed 0xc80c3fDE077Ce7360e738BB6525A92bf7953ea51
Initial SC1: 0x43ba105f5DeC27B9c4183c95971672e53EaA9a64 balance is 11000000000000000000
Initial SC2: 0xc80c3fDE077Ce7360e738BB6525A92bf7953ea51 balance is 0
11 Ether from 0xEa719Cf8f777350c0D0B0be8cc4A90Aa95f36898, sc1: 0x43ba105f5DeC27B9c4183c95971672e53EaA9a64 balance is 11000000000000000000
My script is:
// Contracts
const MySC1 = artifacts.require("MySC1")
module.exports = async function(callback) {
try {
// Fetch accounts from wallet - these are unlocked
const accounts = await web3.eth.getAccounts()
// Set up account to transferEther to Victim
const acc2 = accounts[2]
acc2bal = await web3.eth.getBalance(acc2)
web3.utils.fromWei(acc2bal, "ether")
console.log('acc2 balance', acc2bal, 'address',acc2)
// Fetch the deployed exchange
const sc1 = await MySC1.deployed()
console.log('SC1 deployed', sc1.address)
sc1bal = await web3.eth.getBalance(sc1.address)
web3.utils.fromWei(sc1bal, "ether")
console.log(`Initial SC1:`,sc1.address,` balance is ${sc1bal}`)
amount = '11'
web3.eth.sendTransaction({to:sc1.address, from:acc2, value: web3.utils.toWei(amount)})
sc1bal = await web3.eth.getBalance(sc1.address)
web3.utils.fromWei(sc1bal, "ether")
console.log(`${amount} Ether from ${acc2}, sc1:`, sc1.address,` balance is ${sc1bal}`)
}
catch(error) {
console.log(error)
}
callback()
}
