Secure payment process

Pay for an approved StackPayback service with USDT.

Crypto payment is available only after the project scope and invoice are confirmed in writing. This page explains the process; it does not collect funds or display a wallet address yet.

Payment flow

A clear sequence protects both the buyer and the project.

USDT transfers are generally irreversible. Confirm the scope, network, wallet, amount, and delivery terms before sending.

1. Prepare the brief

Choose a package and describe the workflow without sharing passwords, bot tokens, customer records, or other secrets.

2. Approve the quote

Receive the deliverables, exclusions, price, currency, milestones, timeline, and handoff method in writing.

3. Verify the invoice

Check the exact USDT network and wallet address. The network must match on both sides; do not guess or substitute one.

4. Confirm on-chain

Provide the transaction hash through the agreed contact channel. Work is scheduled only after the required confirmations.

What the invoice must contain

  • Client or project reference
  • Service scope and milestone
  • Exact USDT amount
  • Blockchain network, such as TRON, Ethereum, or another explicitly supported network
  • Full destination wallet address
  • Required confirmation count
  • Delivery method and expected timing

Email and download delivery

Custom bots are not instant downloads. After payment and completion, delivery can include a private repository, deployment handoff, documentation archive, or files sent to the buyer's confirmed email, depending on the accepted quote. Downloadable products can be added later with a payment processor that verifies payment before issuing a time-limited link.

Important safety rules

  • Send only on the network printed on the accepted invoice.
  • Compare the entire wallet address, not only the first and last characters.
  • Use a small test transfer for unusually large payments if the invoice permits it.
  • Do not send from an exchange that cannot provide a transaction hash.
  • Never send a second payment because of an unsolicited message claiming the first address changed.
