I think we can just get rid of this. We wrote this when there wasn't a lot of tooling for solidity development.
We now have a hardhat plugin built in which does this out of the box ,,

I wonder if you can specify the version explicitly as i've done here ..

so I tried a few things here. I could yarn add from the github path as you had, in the case "https://github.com/OpenZeppelin/openzeppelin-solidity.git#2.0.0" actually resolves to "https://github.com/OpenZeppelin/openzeppelin-contracts.git#2.0.0", but the package name remains "openzeppelin-solidity" for purposes of importing from the contract code

I wonder if we can just use the latest solidity versions (and oz dependencies) for the market oracle contracts you've imported? If we redeploy we'll bump them up anyway. We could add an issue and get back to it in a later PR, no rush. |

Open to doing this. Of course, would not match the existing deployed oracle, so maybe better for a separate PR, possibly including any feature update proposals |
Migrates MedianOracle contract to this repository, also migrating the testing from truffle/js to hardhat/ts.
