    1//! # Fee-Less Runtime
    2//!
    3//! 🚧 Work In Progress 🚧
    4//!
    5//! Notes:
    6//!
    7//! - An extension of [`runtime_vs_smart_contract`], showcasing the tools needed to build a safe
    8//!   runtime that is fee-less.
    9//! - Would need to use unsigned origins, custom validate_unsigned, check the existence of some NFT
    10//!   and some kind of rate limiting (eg. any account gets 5 free tx per day).
    11//! - The rule of thumb is that as long as the unsigned validate does one storage read, similar to
    12//!   nonce, it is fine.
    13//! - This could possibly be a good guide/template, rather than a reference doc.
