Is there any way to verify with oz command line. I’ve tried with npx oz verify but look like it doesn’t work. I couldn’t get symbol(), totalSupply() as well as other functions.
Here is step by step what i did with oz command line.
$ npx oz create
The create command is deprecated. Use deploy instead.
Nothing to compile, all contracts are up to date.
? Pick a contract to instantiate TOKENERC20UpgradeSafe
? Pick a network ropsten
✓ Linked dependency @openzeppelin/contracts-ethereum-package 3.0.0
✓ Contract TOKENERC20UpgradeSafe deployed
All implementations have been deployed
? Call a function to initialize the instance after creating it? Yes
? Select which function * initialize(escrow: address)
? escrow: address: 0xDc63C389e72d9f803f5c8fDe241A11e66E8D6531

To upgrade this instance run 'oz upgrade'

No, not yet. I’ve tried with hardhat. but it shows the error something like the contract code mismatch with a deployed address. I will show you the detailed steps that I did with hardhat soon
If you can share the error, I may be able to guide you.
If you get stuck verifying, you can post your address, Solidity code, parameters and whether optimization was enabled and someone may be able to help you verify.
Finally, I can verify the code with hardhat configuration. but it has another issue. it seems that etherescan couldn’t read the state data when i 've tried to read name, symbol, decimals of token contract.
