Is there another way to solve the problem by Openzeppelin? (Verifying a contract inheriting from OpenZeppelin Contracts)
Welcome to the community
I suggest using Buidler’s Etherscan plugin for multifile verification:
If you run into issues, let me know.
I can help verify if you share your contract address, network, smart contract source code and the license being used.
thank you for your enthusiasm very much, my contract has been verified successfully by using your suggestion. I deploied my contract by openzeppelin, so I feel a bit troublesome when I have to use truffle
to initialize my project.
Glad to help.
I much prefer multifile verification rather than flattening which is why I suggested using the Buidler plugin. I hope that we see easy multifile verification everywhere.
The biudler-etherscan works well ! Thank you !
