Provide a brief description of the functionality you're trying to implement and the issue you are running into.

I’ve implemented a smart contract for EVM that focuses on signature verification using EIP-1271 for account abstraction. The contract uses OpenZeppelin’s SignatureChecker.isValidERC1271SignatureNow to verify signatures, and it works as expected on standard EVM networks.

I’m now considering deploying this contract on zkSync Era and was wondering:

• Will the EIP-1271 signature verification work the same way on zkSync Era as it does on EVM?
• Are there any specific considerations or compatibility issues I should be aware of when using SignatureChecker.isValidERC1271SignatureNow on zkSync Era?

Any insights or experiences would be greatly appreciated.

Thanks in advance!

Hey @nerses-asaturyan thank for posting!

We expect accounts to support the EIP-1271 standard. So I dont forsee any issues. I am assuming you will need to interact with system contracts so please remember to enable the enable-eravm-extensions.

You can view related documentation here: https://docs.zksync.io/zksync-protocol/account-abstraction/signature-validation

Happy hacking :)
