Authryn - The trust layer for peer to peer transactions.

byβ€’
Authryn helps buyers and sellers build trust by verifying receipts and proving ownership before a transaction takes place. Instead of relying on screenshots that can be edited, users can create verified receipts backed by identity verification and secure verification codes. Share trusted proof with a QR code and give both sides more confidence when buying or selling valuable items. Pay only for the verifications you use.

πŸ‘‹ Hi Product Hunt! I'm excited to share Authryn with you today. The idea came from a simple problem I kept seeing in marketplaces. Buyers and sellers often ask for a receipt to prevent them selfs from suspecious deals, but screenshots and PDFs are easy to edit, making them difficult to trust. We built Authryn to make receipt verification simple and reliable. Instead of sharing a receipt that anyone can modify, users can create a verified receipt backed by identity verification and secure verification codes. Buyers can quickly verify the information through a QR code, giving both sides more confidence before completing a transaction. Our goal is to create a trust layer for online buying and selling without adding unnecessary complexity. We also chose a pay as you go credit system so people only pay when they actually use the service. We're still early, and your feedback will have a huge impact on where Authryn goes next. Thank you for checking us out, and feel free to ask any questions or share your thoughts. We'd love to hear what you think! πŸš€

A feature like a dispute flag would be really useful, something a buyer or seller can raise if the other party refuses to complete verification. It would give both sides a clear record and an extra layer of confidence when high value items are involved.

Does the verification hold up if the seller later claims they never received the item, or is it more focused just on proving ownership at the time of listing?

Shared a QR receipt for a camera I sold and the buyer actually seemed relieved to have it verified instead of just screenshots. Wish I'd had this when I got burned on a fake game console listing last year.

Building trust before the transaction instead of trying to resolve disputes afterward is an interesting positioning shift.

I'm curious whether your biggest challenge is convincing buyers and sellers they need a trust layer, or convincing marketplaces to adopt it as infrastructure.

Those seem like very different go-to-market paths.
