API Endpoint (Swagger)

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

System Architecture

0. Develop Affondra blockchain application with Starport.
1. Use Firebase Hosting to host Vue application.
2. Use Firebase storage to keep item images that users uploaded.
3. 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.
4. 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.
5. Affondra module is originally created to trade NFT, to motivate affliate, and to certify correct payment.

$ affondracli tx nft mint your-favorite-denom random-nft-id $(affondracli keys show -a user1) --tokenURI http://metadata.com --from user1 -y

Create Item

Now you have a NFT and you can sell it as a Item in the Affondra trading market. Just set the price you want to sell and affiliate reward for those who promote your item.

$ affondracli tx affondra create-item your-favorite-denom random-nft-id 1000affondollar 10affondollar This item is Awesome! true --from=user1 -y
