Contract Not Verifying On Goerli

[Benrockiee]

Can't verify contract on goerli, After deploying and tries to verify, it says:

We tried verifying your contract Race without including any unrelated one, but it failed.
Trying again with the full solc input used to compile and deploy it.
This means that unrelated contracts may be displayed on Etherscan...

Successfully submitted source code for contract
contracts/Race.sol:Race at 0x548dF75d72743596B8B91f01ADE0E0C0805adaBB
for verification on the block explorer. Waiting for verification result...

NomicLabsHardhatPluginError: The contract verification failed.
Reason: Fail - Unable to verify

Goerli has been bugging lately when it comes to contract verification. Try and verify your contract on rinkeby and if everything works out well, then you don't have to be worried about your code. You just have to try verifying the contract on goerli again later when hopefully they'll have fixed the issue on the network.

Try Rinkeby/Kovan. Additionally, a different RPC provider if possible.

[Benrockiee]

@krakxn These chains are no longer available on alchemy, All deprecated except Goerli testnet

[krakxn]

Well, the latter (i.e. "Additionally, a different RPC provider if possible.") then.

The same was happening to me last night with Goerli. I tried at least 20 times, with cleaning recompiling, nothing worked. I even tried manually doing it on Etherscan, didn't work. So I shut the computer down, tried it again today after work and it worked on second try 😀 Nothing to do with the code. Just a buggy goerli!

@Benrockiee Yes, etherscan does this issues sometimes, you can try now or even after some time.

Same was happening to me yesterday but now, I used foundry to deploy and verify successfully.

[GlitzyM]

What is Foundry?

[RohitSingh107]

Foundry is a blazing fast, portable and modular toolkit for Ethereum application development to write tests and deploy scripts all in Solidity! No JavaScript needed! Just Solidity!
