Proven photos
A photo can only be posted if it carries a cryptographic capture signature (C2PA or our own attestation). That means it was taken by a real camera of a real item, not generated, not scraped, not someone else's picture.
Every listing photo is cryptographically proven to be a real camera capture. No AI fakes, no stolen stock photos. Every condition promise is backed by signed video. And every sale closes with a safe, in-person handshake while your money sits protected in escrow.
Launching with phones & electronics first. No spam, just an invite.
Stock-photo scams. AI-generated listings. "Powers on, I swear." No-shows in parking lots. Chargebacks after the handoff. Today you just trust a stranger's word and a star rating. We replaced trust with proof.

Sellers tick the promises that matter, like "powers on", "no cracks", or "battery health 90%", and back them with a tamper-proof signed video. Soon, a model auto-checks the video against the checklist before the listing goes live.
Your money waits in escrow. You meet at a safe public spot inside a set time window and tap phones to release the funds. Both sides put up a small deposit, so no-shows pay for wasting your time.
We use hardware-backed signing (Secure Enclave & TPM) and open provenance standards (C2PA) so authenticity travels with the media, verifiable by anyone, with no central database required. The same technology newsrooms and camera makers use to fight deepfakes, pointed at the thing you're about to buy.
We're rolling out city by city. Drop your email and we'll bring proof to your local marketplace.
