Ocean ONE is a cutting-edge decentralized exchange built on the Mixin Network that aims to provide a user experience similar to centralized exchanges. This tutorial will guide you through the process of using Ocean ONE for trading assets, placing orders, and subscribing to market events.

1. Getting Started with Ocean ONE

• Supported Assets: You can use all assets in the Mixin Network as base currencies. The supported quote currencies are Mixin XIN, Bitcoin BTC, and USDT-ERC20.
• Encoding Orders: All order and trade data are encoded in the Mixin snapshots memo field using base64 encoding with MessagePack.

2. Creating Orders

To create an order to sell or buy assets, you need to structure your transfer properly.

2.1 Selling XIN for BTC

To sell 0.7 XIN at a price of 0.1 BTC:

memo = base64.StdEncoding.EncodeToString(msgpack(OrderAction  T: L,  P: 0.1,  S: A,  A: uuid.FromString(c6d0c728-2624-429b-8e0d-d9d19b6592fa),))

2.2 Buying XIN with BTC

To buy XIN with a price of 0.1 BTC:

memo = base64.StdEncoding.EncodeToString(msgpack(OrderAction  T: L,  P: 0.1,  S: B,  A: uuid.FromString(c94ac88f-4671-3976-b60a-09064f1811e8),))

3. Cancelling Orders

To cancel an order, send any amount of any asset to Ocean ONE with the appropriate encoded memo:

memo = base64.StdEncoding.EncodeToString(msgpack(OrderAction  O: uuid.FromString(2497b2bb-4d67-49bf-b2bc-211b0543d7ac),))

4. Understanding Bid Order Behavior

The Ocean ONE engine handles bid orders by transferring a defined amount to the matching engine, enabling flexibility in trade sizes. The matching engine may fill more than the expected order size in a limit order scenario.

5. Staying Updated with Market Events

To receive updates about market events, you’ll need to establish a WebSocket connection:

• WebSocket Endpoint: wss://events.ocean.one
• Send messages should be gziped for optimization.

5.1 Subscribing to Market Events

When connecting to the events server, send a SUBSCRIBE_BOOK message:

json  id: a3fb2c7d-88ed-4605-977c-ebbb3f32ad71,  action: SUBSCRIBE_BOOK,  params:     market: c94ac88f-4671-3976-b60a-09064f1811e8-c6d0c728-2624-429b-8e0d-d9d19b6592fa

6. Listing Orders

To list your orders, you’ll need to authenticate using JWT and make a GET request:

GET https://events.ocean.one/orders

7. Retrieving Market Data

Ocean ONE offers an authenticated API for accessing market data including tickers, order books, and trade histories. For instance, you can call:

GET https://events.ocean.one/markets:id/ticker

8. Troubleshooting Common Issues

Sometimes things might not go as planned when using Ocean ONE. Here are some troubleshooting tips:

• If you encounter issues retrieving market data, ensure that your WebSocket is connected and correctly gzip compressing messages.
• For order placement problems, double-check your MessagePack encoding.
• Ensure the network connection to the Mixin Network is stable and operational.
