Deploying and upgrading a UUPS proxy

[giladHaimov]

The documentation for Hardhat Deploy and update of a UUPS proxy is somewhat lacking.

Can anyone from the dev team confirm that using the standard deployProxy/upgradeProxy functions with an additional <kind : "uups"> opt is the correct way to handle a UUPS proxy.

That is:

//deploy a uups proxy:
    const _proxy = await upgrades.deployProxy(OrigContractFactory, [initialize -params-here], { 
              initializer: "initialize",
              kind : "uups",
            });



//upgrade a uups proxy:
    const _proxy = await upgrades.upgradeProxy(ORIG_PROXY_ADDRESS, NewContractFactory,  {kind : "uups"});

Thanks.

Are you using the Open Zeppelin upgrades plugin: https://docs.openzeppelin.com/upgrades-plugins/1.x/ ?

@kanej indeed. I'm using OpenZeppelin upgrades plugin for Hardhat: https://docs.openzeppelin.com/upgrades-plugins/1.x/hardhat-upgrades

The Open Zeppelin team maintains that plugin and api but the docs indicate that {kind: "uups"} is a valid property of the opts object:
