@abcoathup Could you please help? i was not able to verify the contract after deploying it from remix

Hi @senavi,

Welcome to the community 👋

Glad you were able to verify. (Thanks as always @Skyge 🙏)

The current best way to verify is as follows: [Verifying a contract inheriting from OpenZeppelin Contracts](https://forum.openzeppelin.com/t/verifying-a-contract-inheriting-from-openzeppelin-contracts/1119)
