Sello is an AI powered marketplace that turns a used phone into a verified listing anyone can trust.
EXPLORE
Guided photo capture, honest cosmetic grading, and an independent price estimate that is never inflated. You set the actual asking price yourself, shown next to the AI's read.
Every appraisal is hashed into a permanent, tamper proof record. Anyone can check the badge actually matches what was recorded.
See every verified listing without an account. Connecting is only needed when you are ready to buy.
Payment is held until both sides confirm the handover. Funds and ownership move together, or not at all.
SELLO IN NUMBERS
HOW IT WORKS
Take 5 guided photos: a live proof code, your phone's model info screen, back, and both sides.
AI grades condition, flags defects, and gives an independent price estimate. You set the asking price.
Get a verified badge, visible on Browse. No account needed to look, only to buy.
Buyer pays into escrow. Funds release only when both sides confirm handover.
FAQ
Cosmetic condition, such as scratches, cracks, and wear, plus a visual authenticity signal. Every listing also requires a live proof code photographed on the phone's own screen and its model info screen, so a stock photo or an old listing photo cannot pass. It cannot check battery health, true IMEI or blacklist status, or lock status from photos alone, and it says so honestly in every report rather than guessing.
Either side can raise a dispute before confirming. Sello reviews the appraisal and evidence trail and resolves it. Funds either release to the seller or return to the buyer.
Yes. A secure account keeps every listing and payment tied to something only you control. Setup takes under a minute and never asks for private recovery information. Settlement is USDT, not naira.
Payment is held safely from the moment the buyer pays, before you hand anything over. It only releases once both of you confirm, or automatically after a set window if one side goes silent.
ABOUT
Buying a used phone means trusting a stranger's word. Sello replaces that with an honest, tamper proof AI appraisal and payment that stays held safely until both sides confirm the handover. Built on X Layer. Currently phones only, in person handover only, one category at a time by design.
