Frequently Asked Questions
Get clear answers on timelines, costs, and technical details for building a custom sponsorship policy engine.
A sponsorship policy engine is a smart contract-based system that programmatically defines, enforces, and automates the rules for sponsoring user transactions (gas fees). It's essential for Web3 applications to improve user experience by removing the friction of gas fees. Without it, you'd need to manually manage and approve gas reimbursements, which is inefficient and insecure. Our engines provide granular control over sponsorship eligibility, budgets, and limits.
