About

The problem it solves - Experts drown in unpaid DMs; no clean way to monetize time per message - Buyers can’t verify payment/fulfillment or keep premium content private - Fragmented UX across chains; privacy vs. auditability trade-off What people can use it for - Paid 1:1 insights (trading/investing, legal/tax, smart‑contract reviews) - Gated research drops and premium Q&A threads - DAO advisory: issue credits to contributors and track spend - Creator “priority inbox” with pay‑to‑reply - Team workflows: multiple experts under one profile with per‑message pricing

How it's made

Challenges we ran into - Coordinating UX across two chains (Base for credits, Sapphire for privacy) - SIWE edge cases (domain/chainId/tuple signature) and wallet network switching - Mapping Base purchases to Sapphire records (ensuring record.client is set) - Provider wrapping (Sapphire) vs. injected providers without disconnects - Keeping the reveal flow on‑chain while maintaining a fast, single‑click UX
