Astar Verification

[tomrowbo]

Confirmation

• My issue isn't already found on the issue tracker.
• I have read the Subscan API documentation (if it seemed to be an API bug).

Affected Network(s)

Astar

Steps to reproduce

I'm encountering difficulties while attempting to verify my WASM smart contract through Astar's Subscan tool. I am using a flipper template contract, and have tried using multiple verification options.

Expected output

It is expected to verify.

Actual output

Despite multiple attempts using various options, the verification process remains inconclusive. Instead of generating an error log, the verification process appears to be perpetually stuck, requiring manual refreshes to determine if verification has failed.

Additional factoids or references

Similar to this ticket but a single file. #59

Would be great to get this fixed. Thanks.

Hi, @tomrowbo, As far as I know, https://contracts-ui.substrate.io/instantiate can only deploy contracts but cannot compile contracts.
