// How it works — three steps
01
Seal the file
Drop any file — contract, statement, disclosure, invoice, design, deliverable. SENT. generates a cryptographic fingerprint of the exact file at the exact moment, before it ever leaves your hands.
02
Send the link — or lock the file
A permanent receipt is created with hash, timestamp, and cryptographic signature. On Solo and above, the file itself stays locked until the recipient acknowledges — and that acknowledgment is sealed into the record.
03
The record is final
Anyone can verify the receipt — no account required. The timestamp is permanent. The acknowledgment is independent. If delivery is ever questioned, the answer already exists.
Gated delivery · Solo and Enterprise

THE FILE STAYS LOCKED.
UNTIL RECEIPT IS CONFIRMED.

With gated delivery, the file is sealed inside the proof. The recipient confirms receipt before they can access it — and that confirmation is permanently recorded with their IP, timestamp, and a cryptographic acknowledgment. The proof is created before any dispute. A timestamp cannot be backdated.

🔒
File stays sealed
Encrypted in secure storage. The recipient confirms receipt before access is granted — every time, without exception.
⛓️
Confirmation is sealed
The recipient's confirmation becomes a tamper-evident layer in the record — sealed with IP, timestamp, and cryptographic acknowledgment.
🔥
Auto-expires
The file is removed shortly after confirmed access — or after a fixed window if never opened. The receipt remains permanent.
📩
Instant confirmation
You're notified the moment receipt is confirmed. The proof was sealed before the confirmation — the sequence is verifiable.
"The proof was created before the dispute. You can't backdate cryptography."
— The principle the entire record rests on
DELIVERY
SHOULDN'T BE
A QUESTION.
The usual record
A sent-folder timestamp. A read receipt that can be disabled. A portal log only one side controls. When delivery is questioned, the evidence is disputable, one-sided, or gone.
The SENT. record
An independent, cryptographically sealed proof of exactly what was delivered, when, and when it was acknowledged — verifiable by either party or a third party. The question is answered before it's asked.

WHAT EVERY RECEIPT CONTAINS

Each SENT. receipt is a self-contained, independently verifiable record for any file or document — contract, invoice, statement, design, disclosure. No account required to open it. No reliance on the sender's word, the recipient's word, or any single platform's logs.

The proof cannot be altered after it's sealed. The timestamp cannot be backdated. The acknowledgment, once confirmed, is permanent.

Second product · Verified Bill of Sale

PROVE WHAT YOU SOLD —
BEFORE THE DISPUTE.

Selling something secondhand? SENT Transfer creates a verified bill of sale: prove what you sold, its condition, and that the buyer acknowledged it — sealed, timestamped, and impossible to backdate, before any dispute can exist. The buyer confirms the item and its condition in writing; that acknowledgment becomes part of the permanent record.

For resellers — sneakers · jewelry · electronics · collectibles
Also supports vehicles & boats
📝
Document the deal
Item, condition, disclosed defects, price, and provenance — captured in one record, with photos, receipts, or inspection reports sealed in as evidence.
⛓️
Seal it cryptographically
The agreement is hashed into a tamper-evident chain and timestamped. Once sealed, the terms and condition can't be altered or backdated.
🤝
Buyer acknowledges
The buyer confirms they received the item as described. That acknowledgment is recorded — so "it wasn't what I bought" no longer holds up.
$4.99per transfer
Pay as you go. No account or plan required — fill out the transfer, pay once at the seal, done.

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 (such as a DMV title transfer or odometer disclosure), and not legal advice. You remain responsible for completing any forms required by law for your item.

ONE RECORD. EVERY SCALE.

Two products, one cryptographic guarantee: proof of delivery for files you send, and a verified bill of sale for items you sell. Priced for how you work — one-off or unlimited.
