Hello, i have the same problem and after trying some of those solutions im still failing. Maybe im doing something wrong. I would really appreciate it if someone could help me, i havent had sleep trying to solve this. Let me know what information you need from me about my token, to help me with it.
Hey Magnus, it seems that I have the same problem as you and I dont fully understand how you used https://abi.hashex.org/ to get the ABI and what you did with it, do you mind helping me out?
Hi, welcome! 
So have you solved your problems?
Nope, I still haven't, i would appreciate any type of help.
So could you please share the contract ABI, and which function are you trying to encode?
My total token supply is 15,000,000
This is the ABI:

There is no parameters for totalSupply(), and the encode data for this function is
totalSupply() => 18160ddd
Sorry for my lack of knowledge, i just followed a video tutorial, which wasnt the greatest. What do i have to do now? Also i will post my original code and the flattened version so you can check it if its not a problem.
This is the code:
pragma solidity ^0.8.6;
import 'https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/ERC20.sol';
contract MyToken is ERC20 {
address public admin;
constructor() ERC20('Earthly', 'ERT') {
_mint(msg.sender, 15000000 * 10 ** 18) ;
admin = msg.sender;
}
function mint(address to, uint amount) external {
require(msg.sender == admin, 'only admin');
_mint(to, amount);
}
function burn(uint amount) external {
_burn(msg.sender, amount);
}
}
Maybe just follow your video tutorial.
Here is a tutorial about how to verify contracts that deploys via the Remix, you can have a look: * Verify erc20 token on etherscan that was deployed through remix:step by step guide
And what is your contract address?
Well on the tutorial, he doesn't verify the token.
Another weird thing, i coded it intending to make my token based on the ethereum blockchain and i paid the fee to deploy the token with ethereum, but it was with ethereum that was on the binance blockchain.
So my token is on the binance blockchain.
The contract is:
0xe5f95c298a4bb1b150beee009105c46b356b3066
I have verified your contract: Contract Address 0xe5f95c298a4bb1b150beee009105c46b356b3066 | BscScan
And just follow the tutorial I shared above.
And for the next time, please search at the forum at first, and then ask questions, thanks!
How do I ask a good question? - General / Meta - OpenZeppelin Community
I prefer to close this topic, if you still can not verify your contracts following all the tutorials I shared above, you can reply under this topic and ping me.

Also, i did follow that forum but was still getting errors. Ill try to do it again and tell you what the exact error is.
