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.

SEAL A FILE — $0.99 → Timestamped · SHA-256 sealed · Verify from any device

SENT creates cryptographic proof of delivery — a tamper-evident record of a file's exact contents and the moment it was sealed, plus any acknowledgment received. It is proof of delivery and receipt, not legal advice, and does not alter the underlying contents of any document. Verification requires no account.

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.
CREATE A VERIFIED TRANSFER → Sealed before the dispute · Buyer acknowledgment recorded · Verify from any device

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.

Third product · Escrowed Payment

DON'T SEND MONEY ON TRUST —
PAY WHEN IT'S PROVEN.

VX Pay holds the buyer's money until the deal is done right. The buyer funds the agreement up front, the seller delivers, and the funds release only when the buyer acknowledges — every step sealed with a Veridex cryptographic proof, before any dispute can exist.

For deals that are too big for trust — sneakers · jewelry · electronics · collectibles · private sales
Escrow of record — not a bank, not a money transmitter
💰
Buyer funds the deal
The buyer commits the agreed amount up front into the escrow agreement. Both sides see the terms — item, condition, price, and exactly what has to happen for the money to release.
📦
Seller delivers
The seller ships or hands over the item and marks it delivered. The buyer gets an inspection window to confirm it's exactly as described — sealed evidence can be attached at every step.
🔓
Funds release on acknowledgment
When the buyer acknowledges, the money releases to the seller — and that acknowledgment is permanently sealed with IP, timestamp, and a cryptographic proof. No "I never got it." No "it wasn't as described."
$7.99per agreement
Pay as you go. No account or plan required — create the escrow agreement, pay once at the seal, done.
START AN ESCROW DEAL → Funds held · Released on acknowledgment · Verify from any device

VX Pay creates cryptographic proof of an escrowed payment agreement and its agreed release conditions. It is a proof-of-agreement and settlement-coordination service, not a bank, licensed escrow agent, or money transmitter, and not legal advice. Funds handling is performed by the connected payment provider (Stripe) under its terms. You remain responsible for completing any forms or obligations required by law for your item or transaction.

ONE RECORD. EVERY SCALE.

Three products, one cryptographic guarantee: proof of delivery for files you send, a verified bill of sale for items you sell, and escrow that holds the money until the deal is proven. Priced for how you work — one-off or unlimited.
