Why Bias Bin
Every trade is proven, tracked, and confirmed
No more sending first and hoping. Proof photos and two-way tracking are required, nothing completes until you both confirm, and every outcome lands on a public record. Accountable — not an escrow or a guarantee.
- 1
Agree the trade
Pick what each side sends. Both confirm the exact terms before anything ships.
- 2
Prove it & ship
Both photograph the real card and ship with tracking. No proof, no progress.
- 3
Both confirm
It only completes once you both confirm delivery — then you each leave public reputation.
