I’ve verified your contract now. We currently rely on manual verification once for each network (afterwards it’s cached by Etherscan/Polygonscan). The Solc JSON Input can be obtained by building the contracts in the repository ([https://github.com/OpenZeppelin/openzeppelin-upgrades](https://github.com/OpenZeppelin/openzeppelin-upgrades)) if anyone is interested to know.

Soon this should be automated.
