"Read as Proxy" & "Write as Proxy" buttons for Contract Verification in HashScan

[bmgentile]

Problem

When verifying contracts, we're unable to have proxy contracts offer the option of "read as proxy" or "write as proxy" (typically displayed as buttons) on Hashscan — this directly links a proxy contract to the contract it is engaging and important for users when performing review of contract verification.

Example: https://arbiscan.io/address/0x794a61358d6845594f94dc1db02a252b5b4814ad#code
An example of a Proxy Contract — we need "Read as Proxy" and "Write as Proxy" buttons displayed on Hashscan

Solution

• Add "Read as Proxy" and "Write as Proxy" buttons when viewing contract verification + included functionality that fits the example above for Arbscan.

Alternatives

None

Could you give us id of your verified contract on hedera network ?

Hey @ericleponner

As an example, this is a Proxy contract - https://hashscan.io/testnet/contract/0.0.4616104?p=1&k=1721737748.124068003
This is the corresponding "implementation" contract - https://hashscan.io/testnet/contract/0.0.4616103?p=1&k=1721645916.344630003

The Proxy contract delegates calls to the implementation contract.

Just so you know, this is just one instance. There are many more Proxy contracts in our suite.

Hi @bmgentile
Thanks for the information.
HashScan offers some support for proxy/logic contracts when they are verified.
Have you tried to verify those two contracts ?

See #978

Hey @ericleponner — thanks for flagging that! We're seeing the proxy logic now 👍

Some feedback related to this:
• Our CTO is an experienced EVM / solidity developer building, deploying, and performing verification using HashScan
• It wasn't intuitive / apparent where to find the proxy contract logic until we went digging based on your suggestion
• We think, in order to align with expectations / intuition for other Solidity developers familiar with Etherscan, that the proxy contract logic in HashScan is more "front and center" and apparent for developers, similar to how the buttons are displayed on Etherscan clones.

@bmgentile can you please provide a link that demonstrates the experience you are looking for?

Hey Simi, sure thing!

Here's an example from Arbscan above.

This one is a verified (proxy) contract.
Do you have a proxy contract which is unverified so that we can see the UI ?
