solana · usdc · attestation layer
Your Solana purchase history is yours, not each merchant's database.
Pay any Solana merchant in USDC. Earn a portable on-chain attestation. The next merchant who opts in can see your track record — and price accordingly. No per-brand loyalty accounts.
1 · Pay
Customer scans a Solana Pay QR and pays USDC. Same transaction that moves the money also mints an attestation.
2 · Earn
Attestations live on-chain, readable by any future merchant. Customer owns the credential, not the merchant's loyalty DB.
3 · Redeem
Every merchant sets up to three policy rules. The second purchase at a new merchant auto-applies the best-matching discount before you sign.
