Private sales deserve proof, not luck.
We verify both buyer and seller on every private sale: ID, face & liveness, bank address. A paper trail that protects everyone.
Your address is never shown to the other party.
Chainr verifies identity without exposing private details. Both parties see a certificate that proves the sale, never each other's personal data.
- Verified legal names, both parties
- Item, condition and agreed price
- Handover confirmation code
- Date and timestamp
- Home address
- ID document photo
- Selfie and liveness check
- Date of birth
ID checks are handled by Stripe Identity. Chainr does not store your ID photo or selfie.
The same three checks. On both sides. Every sale.
Every other platform verifies one party and hopes. Fraud doesn't pick a side, so neither do we. Buyer and seller clear the identical bar.
CHECKS
Real fraud. Real people. Every single day.
Private sale fraud isn't rare. It happens across every category. Chainr was built because the founder lost money to it firsthand.
£400 handed over for a camera; £380 of it was fake. With Chainr the buyer's identity is verified before the handover.
Blacklisted three weeks later, the seller reported it stolen to their insurer. A Chainr certificate timestamps the sale.
Frame number flagged stolen months later; the buyer lost bike and money. A verified seller record changes this entirely.
Four steps to a fully verified handover.
Both parties complete verification. Both are protected. The whole process takes under three minutes.
Initiating party registers
Buyer or seller starts: registers the item, completes Stripe Identity, pays £2.50. Card address verified via AVS.
Other party gets a link
The second party opens a unique sale link, completes the same verification and pays their £2.50. Both now on record.
Handover with a 6-digit code
At the physical exchange the code is shared in person and entered to confirm receipt. The sale is sealed and timestamped.
Both get a certificate
A timestamped PDF is issued to both parties instantly, showing verified identities, item details and handover confirmation. A verified paper trail if the sale is ever disputed.
