How to verify upgradeable contract?

[abcoathup]

Hi @lustig,

@lustig

Since the command line interface is not working for me to verify the single, unflattened contract, do you have any other recommendations?

You should be able to use https://github.com/rkalis/truffle-plugin-verify#debugging with the implementation address. If you get stuck, please create a new topic with your Solidity, address etc.

@lustig

my “upgrades” of the implementation proxy appear to be deploying new contracts altogether.

In your migrations you are actually deploying a new contract using deployProxy.

https://github.com/technoplato/nash/blob/upgrading/migrations/3_nash_v3.js#L7

You need to get the address of the proxy and just call upgradeProxy.

See the following example from the documentation:

// migrations/MM_upgrade_box_contract.js
const { upgradeProxy } = require('@openzeppelin/truffle-upgrades');

const Box = artifacts.require('Box');
const BoxV2 = artifacts.require('BoxV2');

module.exports = async function (deployer) {
  const existing = await Box.deployed();
  const instance = await upgradeProxy(existing.address, BoxV2, { deployer });
  console.log("Upgraded", instance.address);
};

I even have a test as advised from the documentation on unit testing the upgrade

We can unit test our implementation contracts, just like any other contract and deploy using .new.

We can also write higher level tests using deployProxy and upgradeProxy.

For an example please see OpenZeppelin Upgrades: Step by Step Tutorial for Truffle

Also the example in the documentation: https://docs.openzeppelin.com/upgrades-plugins/1.x/truffle-upgrades#test-usage

As an aside, I recommend creating a new topic per major question so that anyone can answer.
