Domain Separator / EIP712

The Xacronum contract implements the EIP712 standard through a domain separator, ensuring that off-chain signed messages are secure, unique, and resistant to replay across different blockchains.

Key Advantages:

• Replay Attack Prevention – Ensures that signatures valid on one chain cannot be reused on another.

• Cross-Chain Security – Strengthens interoperability while preserving integrity.

• Auditability – Makes signed data human-readable and easier for third-party auditors to validate.

This cryptographic safeguard strengthens trust in off-chain approvals (such as permit()), ensuring that every signed transaction is verifiable and tamper-proof.
