How does it help with an 'arrived broken' or 'not as described' claim?

The record is sealed before you ship and timestamped cryptographically, so it cannot be backdated. You have a dated, tamper-evident record of the working condition, accessories and photos you both agreed to at the point of sale.

You can pay per transfer, or create unlimited transfers on a Solo plan. The same cryptographic guarantee applies either way.

A BILL OF SALE FOR ELECTRONICS THAT STICKS.

Q: Is a SENT. bill of sale for electronics a legal document?

It is cryptographic proof of a transaction and its agreed terms — what was sold, by whom, to whom, when, and in what condition. It is not a legal title transfer and not legal advice. It is independent, tamper-evident evidence you can show a buyer, a marketplace, or a payment processor.

Before you ship a phone, laptop or console, seal the serial number, IMEI, working condition and photos into a cryptographic, tamper-evident record. When a buyer later claims it arrived broken, that the serial doesn't match, or that the unit is stolen, the proof of exactly what you sold already exists — dated and unalterable. The proof exists before the dispute can.

// The dispute this prevents

"IT ARRIVED BROKEN — AND THE SERIAL'S WRONG."

Used electronics are the easiest category to dispute and the hardest to defend. A buyer claims the screen was cracked on arrival, that the battery is shot, that the IMEI is blacklisted, or that the serial doesn't match what you listed — opening the door to a swap, where they return a broken unit in place of the working one you sent. On a marketplace, the seller almost always loses these without independent, dated proof of what shipped.

Without a sealed record

A listing photo with no provable date. A serial typed into a chat. No record of the unit powering on before it shipped. When the buyer claims a swap or a fault, you can't prove which device you actually sent.

With a SENT. bill of sale

A dated, cryptographically sealed record binding the serial, IMEI, working condition and the actual photos to this exact unit — created before it shipped and impossible to backdate. A return swap can't pass for the device you sold.

// How it works — three steps

Describe the device

Enter the buyer and seller, the price, and the device specifics — serial number and IMEI. The category form surfaces exactly the fields an electronics sale needs.

Add the evidence

Attach photos of the device powered on, the serial/IMEI screen, any cosmetic flaws and the accessories included. Every file is hashed in your browser before it uploads, so the images are sealed exactly as they are.

Seal & send

The record is sealed with a timestamp and signature, and the buyer gets a link to acknowledge the terms. Their acknowledgment is sealed into the same record. Anyone can verify it — no account required.

// What gets sealed

EVERYTHING THAT SETTLES THE ARGUMENT.

✓Serial number — binds the record to this exact unit.
✓IMEI — for phones and cellular devices.
✓Working condition & disclosures — faults you declared up front.
✓Condition photos — powered-on, serial screen, hashed before upload.
✓Provenance — where it came from and that it's clear to sell.
✓Buyer's acknowledgment — sealed with timestamp and IP.

Is this a legal document?

It's cryptographic proof of a transaction and its agreed terms — what was sold, by whom, to whom, when, and in what condition. It is not a legal title transfer and not legal advice. It's independent, tamper-evident evidence you can show a buyer, a marketplace, or a payment processor.

Why record the serial number or IMEI?

The serial or IMEI binds the record to the exact unit you sold. If a buyer claims you shipped a different device, or accuses you of selling a blacklisted unit, the sealed serial and your dated photos show precisely what left your hands.

A VERIFIED BILL OF SALE FOR ANYTHING YOU SELL

Important

SENT. Transfer creates cryptographic proof of a transaction and its agreed terms only. It is not a legal title transfer, not a substitute for any state-required form, and not legal advice.

SEAL THE DEVICE. SETTLE IT FOREVER.

Every device you ship without a sealed record is a swap or chargeback you can't fight.
