Why when i execute setIfSignatureMatch function
it show message in metamask like following
"We were not able to estimate gas. There might be an error in the contract and this transaction may fail."

after i hit proced anyway and submit, the transaction is reverted

Just small comment: in App.js you wrote var deadline = Date.now() + 100000; But I think that on the level of JS we are working with milsec and solidity is in seconds. What means that condition from your smart contract will always be evaluated to true or false.

What I think you should do is divided Data.now() with 1000 then plus lets say 1000 and then we will get comparable value for smart contract to evaluate.

In any case thanks for example, it was very useful for me!

Best regards!

Hi did u write a typo ? cause i cannot compile the smartcontract, but when i change the i into uppercase its work
assembly {
chainId := chainid
}
