Challenge Bid - No check for balance

[samclassix]

How to recreate

• Set a bid
• Make sure, you have less ZCHF then the calculated amount within the smart contract
• e.g. Expected total price: 8000 ZCHF, have less the 8000 ZCHF
• triggers error by reverting tx with no error handling or message
• error in console.log
• UI/UX improvement needed

I. cancel challenge, works II. transferFrom, needs balance calc and check on app, otherwise SC will throw an error

Most likely Smart Contract Error Signature?: 0xe450d38c

if (msg.sender == _challenge.challenger) {
            // allow challenger to cancel challenge without paying themselves
} else {
            zchf.transferFrom(msg.sender, _challenge.challenger, (size * liqPrice) / (10 ** 18));
}
