Reputation-gated cross-border payment rails for African freelancers on Sui — Sui Overflow 2026 # Kano Rails Reputation-gated cross-border payment rails for African freelancers, on Sui. Live: **kanorails.vercel.app** ## What it is Every settled payment, every client attestation stacks on a Sui object owned by the freelancer. Tier — Bronze / Silver / Gold — determines fee rate, offramp priority, and whether Kano sponsors the client's gas. Trust travels. ## How it's built - **Frontend** — Next.js 16, TypeScript, Tailwind 4, `@mysten/dapp-kit`, Framer Motion - **Move** — `ReputationObject` (owned, additive, dispute-driven downgrade) and `PaymentObject ` (shared, tier-snapshot locked at creation) - **Client UX** — zkLogin + sponsored transactions, so a payer with no wallet can pay with a Google sign-in and a card ## Why Sui Owned objects make reputation a first-class asset in the user's wallet, not state inside a contract. Move composability lets any future Sui protocol read the same reputation object. And Sui is the only major chain where zkLogin + sponsored transactions can deliver a walletless, gasless client experience without account-abstraction hacks. ## Submitted to Sui Overflow 2026 — DeFi & Payments track. ## Repo layout ``` app/ — Next.js frontend move/ — Move package (kano_rails::reputation, kano_rails::payment) ```
