Backend Wallets Cover Transaction Fees in Midnight's Frictionless Onboarding Model

Midnight's DUST sponsorship mechanism solves a critical onboarding challenge by allowing backend wallets to cover transaction fees for users who haven't yet accumulated DUST capacity. This approach eliminates the cold-start problem where new users cannot make their first transaction due to zero DUST balances, while preserving privacy and transaction signing integrity. For DApp developers, this opens the door to seamless user acquisition without relying on pre-transaction DUST distribution or external funding mechanisms.
