How to verify uups proxy contract on Remix

Support Upgrades
1

Hi,
I used the wizard to create a erc20 contract with

features: mintable, burnable, pausable, permit
access control: roles
upgradeability: uups

The contract was compiled and deployed successfully through remix as

proxy address: 0x61e24Ce4efe61EB2efd6AC804445df65f8032955
implementation address: 0xadE5f7f7a3f8DB0A9256567e55fF793e3c9bBF14
default admin: 0x7Ec4b6B2525d9aa8287456eB5cfbc5377402A9c7
pauser: 0x7Ec4b6B2525d9aa8287456eB5cfbc5377402A9c7
minter: 0x7Ec4b6B2525d9aa8287456eB5cfbc5377402A9c7
upgrader: 0x7Ec4b6B2525d9aa8287456eB5cfbc5377402A9c7

Then I used the remix plugin to verify the contracts but seems like only the implementation contracts has fully verified similar to

I tried to verify the proxy contract with flatten ERC1967Proxy.sol with ABI encoded constructor arguments

What should I do to make it fully verified? Thanks.

The proxies deployed by Remix are precompiled by Remix and must be verified using the way that Remix docs describe. See https://remix-ide.readthedocs.io/en/latest/contract_verification.html#verifying-a-proxy-contract

3

I've tried it with ERC1967Proxy.sol and once I selected the contract, there was no textbox for constructor arguments.

Then the Remix shows

The proxy's (0x61e24Ce4efe61EB2efd6AC804445df65f8032955) implementation contract is found at 0xadE5f7f7a3f8DB0A9256567e55fF793e3c9bBF14 and is successfully updated.

as expected but I still got

Are you the contract creator? Verify and Publish your contract source code today!
Note: We also found another 6 contracts with exact matching byte codes

in etherscan.

I believe that ERC1967Proxy.sol is the contract to be passed for the proxy verification but the code created by the wizard didn't include it into .dep during the compilation. Did I used the wrong contract?

4

ERC1967Proxy.sol would not be in your compilation, because as I mentioned above Remix is using precompiled bytecode for the proxy itself. If you cannot get the Remix documented steps to work (ensure you are looking at the "Verifying a proxy contract" section), you may need to contact them for support.

Solved.
Successfully verified on Etherscan using flatten ERC1967Proxy.sol but had to use the compile configuration from Remix
