API Endpoint (Swagger)

You can refer to the api endpoint of Affondra module and NFT module.
View in Swagger Hub.

System Architecture

1. Develop Affondra blockchain application with Starport.
2. Use Firebase Hosting to host Vue application.
3. Use Firebase storage to keep item images that users uploaded.
4. Use Firebase cloud functions to set a faucet function. The faucet account mnemonic keys are stored in the cloud service so that users can get faucet with no time and try our product quickly.
5. Nginx is used for load balancing and cors setting. It seems that rest server won't response to OPTIONS method request so we proxy frontend request using Nginx server.
6. Affondra module is originally created to trade NFT, to motivate affliate, and to certify correct payment.
