I think you have deployed the contract on the Rinkeby network, and you have verified the proxy contract, but where is the implementation contract and which function are you trying to call?

Hi @Prabhakaran,

Can you verify the implementation contract:

I suggest using the following: Verify smart contract inheriting from OpenZeppelin Contracts

yes @skyge I deployed the contract on rinkeby network and and i tried to check it through console itself by running commands like …
$ npx hardhat console --network rinkeby

const Box = await ethers.getContractFactory(“Box”)
undefined
const box = await Box.attach(“0xFF60fd044dDed0E40B813DC7CE11Bed2CCEa501F”)
undefined
(await box.retrieve()).toString()
‘42’
like this I tried to call my function…
and i will verify it on etherscan and send contract address shortly…

Hi @abcoathup,
I didn’t verify it on etherscan i just tried to run it on console …as i mentioned on previous reply…
I will verify it and send contract address …shortly as possible.
