Stitch Protocol · x402

A high-stakes networking layer where every 'Handshake' is a metered smart contract. Instead of passive browsing, designers pay 0.01 USDC to unlock a peer's private portfolio, propose a collaboration, or digitally sign a non-disclosure agreement. By attaching a micro-cost to outreach, the platform eliminates spam and ensures every connection is backed by a verified, on-chain intent. Designers earn instantly for their time, and brands pay-per-view for talent scouting.

The primitive.

full primer →

Access to the designer networking engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so fashion designers — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveBy moving from 'gasless' to 'micro-paid,' we transform networking from a social activity into a professional commodity market. The x402 primitive treats a profile view or a DM as a billable unit of intellectual property access.
