tomox-sdk's Issues

Support order nonce 0

Currently, TomoX-SDK does not support order with nonce 0, but tomox supports it. So we should fix on TomoX-SDK side.

Fix unnittest

Need to make current unittest success, then travis can pass the tests

Allow a token to be either base token or quote token

At the moment with our current configuration in code, one token is only allowed to be base OR quote token.
This will cause an issue later when we need to have more pairs, for example:

ETH/BTC
TOMO/ETH

Integrate With TomoX: Handle MongoDB Real-time Changes

Remove redundant config params

Support Price Alert

As a user, I want to set the price alert so that when the latest price crosses above or below the target price, I will receive an email notification.

Portfolio page, show incorrect USD price

USD price should be > 10K USD

Allow user to choose favorite tokens

List of cancelled orders is empty

in ALL tab, there are some cancelled orders and open orders but when I click on CANCELLED tab, there is nothing there

Fiat Price (USD)

We need to track the price of coins/tokens by USD in real time

Add APIs for Market maker team

Cache 10 minutes for price data get from coinmarketcap or coingecko

Currently, we get the prices from conmarketcap, the request number is limit, so we should cache data data to decrease the request to get prices

Add Markets tab to keep track of price between base tokens and quote tokens

It is similar to the Markets section on Kucoin:

Time interval is 1m but close time and open time is equal. If i change time interval is 5m => range of close time and end time do not equal 5m.

Pls check!

closeTime, openTime is not correct for OHLCV api

Refactor getOrderCount

Currently, we get order nonce by count the number of order in orders table
https://github.com/tomochain/tomox-sdk/blob/b31b7926a4a888d2abc73275cf44871786c60687/endpoints/order.go#L87
It is not correct if user create 2 orders with nonce 1 and 10. getOrderCount will return 2, but the correct value is 10.

So the correct value is max of nonce of order

Integrate Swagger UI For Documentation

Allow to swap ETH from Ethereum blockchain

A user can deposit ETH directly into DEX by using Deposit functionality.

Steps:

A random address X (that managed by DEX) will be generated
User sends native ETH (on Ethereum blockchain) to this address X
DEX scans Ethereum blocks
DEX processes Ethereum transactions in each block to find the transaction with exact To address (that equals to X) and get the transaction Value
DEX send corresponding ETH tokens (on Tomochain) to the wallet that user manages
Done

Need to optimize getPairData, getOLCV

Issue:

order by pricepoint, but pricepoint is string, not int
Super slow query in mongodb

Optimization:

Integrate dex with Tomochain Testnet

Deploy contracts to Tomochain Testnet
Connect dex-server and dex-client to Tomochain Testnet

Real-time Markets Page

At the moment, the prices in Markets page are not updated in real-time because this page calls REST API only.

We will add WebSocket to make it "lives"

Implement Index by USD

In the Markets page, we will have BTC Index, ETH Index, XRP Index, TOMO Index. All index is calculated by USD fiat.

Solution: We have to run cron to periodically fetch USD price for these cryptocurrencies and save in the collection "fiat_price"

Verify coinbase (exchange address) ownership

The owner of a relayer can only use a coinbase address (exchange address) that he has the private key.

Use coingecko APIs to get price chart

APIS: https://www.coingecko.com/api/documentations/v3
We can get the data with no cost

Optimize logs

At the moment, there are many unnecessary logs (most of them are for debugging in the development phase)

We need to optimize it so when the server runs in production mode, it doesn't eat up too much space and performance
