Few days ago , a NFT public sale caused a lot of "out of gas" failed transactions
(contract address:
0x9c80777cae192e5031c38a0d951c55730ecc3f5e)
The official says it is because the out of date version of user's metaMask wallet or it is because users set lower gas limit, they don't admit anything wrong with their smart contract.
But I don't think so.
Could somebody find out the real cause of the "out of gas" failed transactions of their smart contract?
