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.
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: verified identities, item details and handover confirmation. Admissible evidence.
