How to verify contracts deployed to telos network using hardhat

[markeddolphin]

I deployed contracts to telos testnet and tried to verify them via hardhat.
But I couldn't find api key for teloscan like in the other evm based chains.
Is it impossible to verify contracts using hardhat for telos?

You do not need a key at all just use the hardhat deploy sourcify plugin

npx hardhat --network testnet sourcify

You may run into a "gateway timeout" error message, do not worry, the contract will still be verified
You can make sure it is by running the command again, you should get this message back:
already verified: MyContract (0x2A3b40A59109a84ab82a0Ff1A3910bb595082e09), skipping.
