@CedarMist @matevz is it possible to verify the contract with @nomicfoundation/hardhat-verify?

I see the package inside https://github.com/oasisprotocol/sapphire-paratime repo, but it is not used anywhere. Are there some limitations, preventing us from using this package?

Good idea. The last time I checked hardhat-verify only supported blockscout, but now I see that sourcify support is also there. Feel free to try it out.
