A Win-Win for Efficiency and Security: The automated Gas operating logic of the Q402 Layer optimizes the on-chain experience in high-frequency trading and complex governance, where Gas fees and multi-account operations often act as invisible killers of efficiency. By leveraging the technical synergy of EIP-7702 and Sign-to-Pay, Q402 Layer thoroughly improves this experience.

Thanks to EIP-7702’s smart execution capabilities for ordinary accounts, Q402 enables users to initiate Sign-to-Pay (signature to pay) and bundle multiple operations for batch processing, while also supporting a flexible Gas paymaster mechanism. More importantly, this entire workflow is fully controlled by the Policy-Aware architecture—paymaster limits and execution conditions are strictly governed and restricted in advance through governance rules. This development not only enhances the user experience, but also provides institutional treasuries with a precise toolkit that balances cost control with automated execution. $Q
