I am a newbie in Solidity. I am learning by reading official docs, i.e. Solidity I am trying to get the balance of an address in solidity using the simple balance method. Below is my code:
pragma solidity ^0.5.1;
contract Firstry {
address abc = 0xCBD6832Ebc203e49E2B771897067fce3c58575ac ;
abc.balance(unit 256) ;
}
Upon trying to compile it, I am getting the following error:
ParseError : Expected Identifier but got '('.
Can anyone please help me with what I am doing wrong?
what you're doing wrong is how you are trying to get balance.
.balance is a simple readable property of address not a function so you can will have to call it just by using
address.balance; instead of address.balance();
that was the main problem.
now you will have to assign the value to a variable and then get that value using a function.
here is the complete code
contract test {
address myAddress = 0xCBD6832Ebc203e49E2B771897067fce3c58575ac;
uint256 balance = myAddress.balance;
function getBalance() public view returns (uint256) {
return balance;
}
}
Here is link to docs of solidity version 5.17
if you're starting just now i would advise you to learn using latest docs instead of much older version
you are trying to call balance on a variable. This would be equivalent of doing something like:
let address = "0xCBD6832Ebc203e49E2B771897067fce3c58575ac";
console.log(address.balance(uint256 1);
To get the contract balance you can do this:
address(this).balance
