Pay for a service

Use this page to request and pay for custom work — a calculator or web calculation tool built for your site, or a data and research task.

How it works

  1. Send the inquiry below with your name, email, the service you need, a description of the work and the agreed amount in USD.
  2. Pay with crypto on the next screen, directly to the site owner's wallet — no middleman, 0% platform fee; you pay only the network fee. Send the exact address and amount shown there.
  3. The status page tracks confirmations on the blockchain — refresh it or revisit it at any time to see where your payment stands.
  4. We start work once the status shows Completed.

USD figures are estimates based on the rate shown on the payment page; the crypto amount on the payment page is the exact amount to send.

Crypto payments are not enabled yet — wallet setup in progress. You can still submit the form below as an inquiry; payment activates once wallet setup completes and the payment page will explain its status.
