Frequently Asked Questions on Encrypted Bundling
Get clear answers on how our encrypted user operation bundling service protects your users and accelerates your product roadmap.
Our service encrypts user operations (UserOps) before they are submitted to the mempool, preventing front-running, transaction data theft, and malicious MEV extraction. This ensures sensitive data like token amounts and recipient addresses remain confidential until execution, a critical requirement for institutional and high-value DeFi applications.
