Hi @kaenderr,

Welcome to the community 👋

I am sorry you had issues verifying.

I recommend specifying the release tag when importing from GitHub, otherwise you will get the latest code in the master branch which could change over time. See the Remix documentation:

> **[Importing Source Files in Solidity — Remix, Ethereum-IDE 1 documentation](https://remix-ide.readthedocs.io/en/latest/import.html#importing-from-github)**

For multi-file verification I recommend using the following method to verify contracts: [Verify smart contract inheriting from OpenZeppelin Contracts](https://forum.openzeppelin.com/t/verify-smart-contract-inheriting-from-openzeppelin-contracts/4119)

Feel free to ask all the questions that you need.
