USDT Deliver — a USDT checkout for WordPress

One shortcode turns any page into a crypto checkout: the buyer pays from their wallet, pastes the transaction hash, and your site verifies it against the Ethereum network and unlocks the file. No API keys, no accounts, no cron jobs, no WooCommerce.

What your customers see

One box, and the file unlocks itself

The shortcode renders a calm, white payment box: the price in USDT, your wallet with a Copy button, and a hash field. The buyer never registers, never leaves an email, never waits for a human.

  • The receipt is read from Ethereum itself — payment confirmed before the file moves
  • Clear message for every miss: pending, reverted, wrong network, underpayment
  • Replay guard: one transaction pays for one product, re-downloads stay free
  • Price and file are signed with your WordPress salts — DevTools edits change nothing

The integration

A shortcode is the whole setup

No SDK, no webhook, no developer. Drop this line into any page or post — the plugin signs the price server-side and renders the box you see on the right.

Ethereum network (ERC-20) · send from Trust Wallet or any wallet — one payment unlocks this file.

Live preview — copy works; verification runs on your WordPress site.

Why it's worth it

Selling crypto, without the crypto work

◍

Verified on-chain

The receipt is read from Ethereum; every USDT transfer to your wallet is summed until the price is covered.

▤

Replay protection

One hash unlocks exactly its own product. A second item refuses it; the same buyer re-downloads forever.

▣

Tamper-proof price

Price, product and file are HMAC-signed with your WordPress salts and re-checked on every request.

✦

No API keys, ever

Six public endpoints ship as defaults — no explorer accounts, no cron jobs, no service that can expire.

Every screen

Buyers pay from their phone

Most crypto payments start in a wallet app, so the box is built thumb-first: one field, one button, a Copy that falls back gracefully, and room for long hashes to breathe.

  • Tested from 320 to 1440 px — no horizontal overflow anywhere
  • Clipboard API with an execCommand fallback for older browsers
  • Status messages announce themselves to screen readers (aria-live)
  • Styling lives in one commented CSS file — re-skin it to match your theme

Delivery

Three steps, no account needed

The buyer pays in crypto, they get the file. Nobody watches a wallet.

01

Pay 19 USDT

The buyer sends the price to your wallet from Trust Wallet or any other — Ethereum, ERC-20.

02

Paste the transaction hash

The hash is the receipt: pasted into the box on your page, no account and no email required.

03

The file unlocks itself

Your site reads the receipt from the network, confirms the amount and serves a signed download link — day or night.

Pay with USDT

19 USDT

Network: Ethereum (ERC-20) · Token: USDT · Amount: 19

0xE1E3e1c2978c74f43Bb095023135C3278303aF34
  • Send only USDT on Ethereum — other tokens or networks are lost forever.
  • Take a screenshot of the transaction, you will need its hash.
  • Network fees are paid by the sender.
Step 2

The file unlocks itself

Open the delivery page and paste your transaction hash. It reads the Ethereum network, confirms the amount and starts your download instantly.

  • Runs 24/7 — pay at 3:00, download at 3:01. No account, no email required.
  • Your hash re-opens the download any time, months later.
  • Chain check broken? The delivery page has a one-click email fallback.

After purchase

Four steps to your first sale

Everything ships in one zip. If you can paste a shortcode, you can install it — typical time is under five minutes.

01

Upload the plugin

Plugins → Add New → Upload → choose the zip → Activate. Or copy the usdt-deliver folder into wp-content/plugins/.

02

Set your wallet

Settings → USDT Deliver → paste the USDT address payments should land on. The contract and the six public RPC endpoints already have sensible defaults.

03

Upload your file

Drop the product into the Media Library and note its ID from the URL (post=123 → 123). Paths inside wp-content/uploads work too.

04

Paste the shortcode

Anywhere in WordPress — page, post, landing page:

[usdt_deliver price="19" product="My Digital File" file="123"]

Test it honestly first: send 1 USDT from your own wallet to your own address — you only pay the gas — paste that hash, and watch the file unlock. The plugin ships with its own test suite (php tests/run-tests.php, 21 checks including a live on-chain proof), and the full message-by-message troubleshooting table lives in INSTALL.md inside the zip.

FAQ

Before you buy

Which network does it verify?

Ethereum mainnet, USDT as an ERC-20 token. Say it once on your sales page — the box already shows it — and payments on Tron, BNB Chain, Base or Solana will be refused with a clear “wrong network” message instead of silently succeeding.

Do I need API keys or an account anywhere?

No. The plugin reads public JSON-RPC endpoints directly — six ship as defaults, and you can add your own. There is no explorer account, no API key, no usage bill and no service that can shut down.

Can the buyer fake the price or the file?

No. Price, product and file are signed server-side with your WordPress salts; the verification endpoint re-checks the signature before it ever touches the network. Editing the form changes nothing.

Can one payment unlock two products?

No. A hash is recorded against the product it paid for, and reusing it elsewhere is refused. The same buyer can re-download their own purchase as often as they like.

Do I need WooCommerce or a page builder?

No. Any theme, any page: one shortcode per product. WooCommerce can keep handling your physical goods while this takes the digital ones.

How do I test it without losing money?

Send a small amount from your own wallet to your own address — a self-transfer costs only network gas and proves the whole loop: box, hash, verification, signed download.
