Additional Details

I am not able to link proxy contracts with their implementation on zkSync explorer.
Etherscan has option 'Is this a proxy?' in Contract -> Code tab which allows using implementation ABI on proxy contract. I don't see similar feature in zkSync (at least on testnet). Without such link I can't call transactions using explorer even if the contracts are verified.

I deployed contracts (transparent proxy + implementation) and verified them according to hardhat-zksync-upgradable and hardhat-zksync-verify docs. Now I have both contracts verified, but still can't call implementation ABI from proxy.

Proxy: 0x0c3437C2F8be296927b2A152C42541d6414C8Ba9

Thanks for the feedback. As you said, currently the explorer does not link the proxy and implementation contracts, so you cannot read/write directly from the explorer and pointing to the active implementation contract. That said, this was already in our pipeline so it should be added to the explorer in the upcoming weeks.

Little bird told me this is coming quite soon

There's now a banner in proxy contracts on the contract verification on the block explorer with a link to the implementation contract

Looking forward to the progress of this feature.
