It looks like vyper work on the API for the block explorer. Does anyone have an example of this per chance?

To verify Vyper contracts on the ZKsync Era network using the Hardhat plugin, you need to ensure that the Vyper smart contracts list in your project's "contracts" folder is exactly the same as it was during the deployment of the specific Vyper contract. This is crucial because any discrepancy will result in a "bytecode doesn't match any of your local contracts" error. It's strongly recommended to verify your Vyper smart contracts immediately after their deployment to minimize such issues.

For more detailed guidance on using the Hardhat plugin for Vyper verification, you can refer to the hardhat-zksync-verify-vyper documentation.

If you are looking for examples of Vyper work on the API for the block explorer, unfortunately, I couldn't find specific examples in the provided documentation. You might want to check the official repositories or community forums for more detailed examples or guidance.
