We use a typical client-server architecture, except that both are hosted in the same canister container on the Internet Computer. This technique is made possible by Motoko Http Server.

• The backend server keeps transaction records, and integrates with Stripe, a payment gateway service.
• HTML and Javascript frontend handles user input, shows payment link, and confirms after a successful payment.

The backend is written in Motoko, and frontend in Javascript and Webpack. Build environment requires nodejs, vessel and pandoc to be in PATH. Just type make to build both frontend and backend from source.

The deployment takes 2 steps:

• Deploy canister code with the required initialization parameters. This can be done from ic-repl.
• Upload frontend assets to the canister. This can be done by using an upload.js script.

The deployed canister id is 4r37y-mqaaa-aaaab-aadqq-cai. Anyone can verify that the deployed Wasm hash (as well as frontend html and javascript) should match what is built and released on github.
