It appears that you are encountering a compilation error during the verification process of your contract GasliteDrop on the Abstract Testnet. This issue might be related to the specific settings or versions used in your deployment and verification commands.

Here are a few steps you can take to troubleshoot and potentially resolve the issue:

1. Check Compiler Versions: Ensure that the zkSolc version used for deployment matches the one used during verification. Discrepancies in compiler versions can lead to bytecode mismatches.

2. Review Contract Code: Sometimes, subtle issues in the contract code can cause compilation errors during verification. Review your contract code for any potential issues that might not affect deployment but could impact compilation during verification.

3. Manual Verification: Try manually verifying the contract through the block explorer's UI if available. This can sometimes provide more detailed error messages or different results.

4. Update Tools: Ensure that all your tools (foundry, forge, etc.) are updated to their latest versions. Sometimes, bugs in earlier versions can cause unexpected issues during contract interactions.

5. Consult Documentation: Review the ZKsync documentation for any updates or notes on contract verification that might be relevant to your issue.

If these steps do not resolve the issue, you might want to reach out for more specific support or check if there are any known issues with the tools or network you are using. For more in-depth discussion and support, you can visit the ZKsync developers discussions on Github.

Your feedback helps us serve you better. If this fully addresses your question, please give it a thumbs up. If it doesn't, please give it a thumbs down. This will inform the community and team so we can improve our support.

It seems like this may be compiler version related?

Changing the pragma to ^0.8.24 fixes the verification issues, but this shouldn't be required for verification.

Verified deployment here succesfully: https://explorer.testnet.abs.xyz/address/0xa28EBcbda3762A24ABF7BF72441290B592382e9B#contract

I was able to replicate this on ZKsync Era and had the same things where it worked after changing it to ^0.8.24 I'll check with the compiler team and see if there is a cause for that.

@coffeexcoin I see the issue is with the verification request from foundry-zksync. I am working on a fix. I was able to successfully verify via hardhat but will update here when the PR is merged! Thanks for posting sir 🙏

[bxpana]

I just submitted a PR to your repo that adds a foundry.toml file to use zksolc 1.5.6 that works with deploying and verifying.

[dutterbutter]

@coffeexcoin will be fixed once matter-labs/foundry-zksync#690 is merged, release will automatically roll out tonight.

Again thanks for posting sir 🙏
