Guys i'm trying to make an NFT contract but minting should be with ERC20 token that i have created before, i always get en error something like: gas estimation, your transaction is gonna fail. I'm too tired of it, i almost tried everything. Any example someone of you have that i can see and learn what my mistake is?

Any ideas? 😄

Use erc1155

Hard to tell without seeing the code. Can you post the minting function?

function mint (uint256 _mintAmount) public payable {
uint256 supply = totalSupply();

require(_mintAmount > 0);
require(supply + _mintAmount <= maxSupply);

if (msg.sender != owner()) {
require(!paused, "MINTING IS PAUSED");

require(_mintAmount <= maxMintAmount, "YOU CAN'T MINT MORE THAN MAX AMOUNT PER TRANSCTION");

IERC20(MyERCTokenAddress).basicTransferFrom(msg.sender, address(this), 100);
uint256 ownerTokenCount = balanceOf(msg.sender);
require(ownerTokenCount < nftLimitPerAddress);
require(msg.value >= cost * _mintAmount);
}


for (uint256 i = 1; i <= _mintAmount; i++) {
_safeMint(msg.sender, supply + i);
}
}

IT should be edited for sure, i need to remove the bnb cost check, but just need to get it work first

I approved before on the ERC20 manually

This is the basicTransferFrom function

function basicTransferFrom(address sender, address recipient, uint256 amount) public returns (bool) {
_approve(sender, recipient, _allowances[sender][recipient].sub(amount, "ERC20: transfer amount exceeds allowance"));
_balances[sender] = _balances[sender].sub(amount, "Insufficient Balance");
_balances[recipient] = _balances[recipient].add(amount);
emit Transfer(sender, recipient, amount);
return true;
}

You're testing on testnet and you have tried with different gas amounts i assume?

IERC20 interface i used has also this function

function basicTransferFrom(address sender, address recipient, uint256 amount) external returns (bool);

On test net yes but i did not tested different gas amounts

Try calling the function with more gas

Ok thanks, will try

Is there a reason why the function is defined payable? Looks like you don't need that.

Yes that's right, i will remove it

I got this error

before even confirm it

i sent the transaction and tried with very high gas fees

but it failed

are you using a router?

Yes pcs test router

and you are on which chain

binance test chain

show testnet router

This is on the ERC20 side for sure

Man thank you so much

It worked after i removed payable
