Order meta-data (AppData)

The protocol have some means to attach arbitrary information to any order. This data will be available by using only on-chain data and IPFS.
Orders have some special data field called appData. This is a hex number that directly points to an IPFS document. This IPFS document is a JSON data file with all this arbitrary information.
Some questions that we could ask ourselves is:
  • Which format does it have this JSON file?
  • How do I get the JSON document given an order appData?
  • How do I get the appData given a JSON document?
  • How do I update the file to IPFS?
For all these questions, SDK is the answer 😎
Let's start by creating a basic meta-data document that includes the name of your app, so you can track all the volume you bring to the protocol.
