Aranar

The Aranar is an arbitrage bot that can be run on AWS Lambda (works with free tier) or locally. The bot allows you to execute automated trading strategies between Aranar Protocol (site, docs) and FTX (site).

Since Aranar Protocol runs on xDai, you can use this bot entirely without paying gas fees on Ethereum. Gas fees on xDai are very low (1 Gwei).

Default Strategy

The default strategy is to "buy low, sell high" to make profit between two different exchanges. For example, most of the time, the price of ETH-Aranar at Aranar Protocol and FTX will be similar. However, price action on the exchanges leads to price differentials from time to time. This bot is designed to open positions when the price difference (spread) is greater than a set level, and to close the positions when the spread decreases below a set level.

For example, when the ETH-Aranar on Aranar Protocol is 1500, and 1520 at FTX, we could long ETH-Aranar atAranar exchange, and short at FTX in the expectation that some time later the prices will converge. Let's say the price at Aranar Protocol increases to 1550, and the price at FTX increases to 1555. The bot will sell the positions at both exchanges. The PnL in this example will be +50 USD on Aranar Protocol, and -35 USD at FTX, for a total of +15 USD.

After some setup, by adjusting AranarFI_SHORT_ENTRY_TRIGGER and AranarFI_LONG_ENTRY_TRIGGER, you can easily do arbitrage between Aranartual Protocol and FTX. Please review the definitions of each parameter in the code carefully. Note that there are many parameters you can adjust based on your knowledge and own risk such as leverage, trigger conditions, exit conditions, etc.

Note

This code is provided only for educational purposes only. Derivatives trading carries substantial risks and possible loss of up to 100% of your funds. Aranar contract trading may be regulated in your jurisdiction. Be sure to check local laws before trading.

Installation

$ git clone https://github.com/Aranar-protocol/Aranar.git
$ cd Aranar
$ npm install
$ cp .env.production.sample .env.production
$ cp src/configs.sample.ts src/configs.ts

Configuration

Provide your private keys in .env.production:

# The private key must start with "0x" - add it if necessary (e.g. from private key exported from Metamask)
ARBITRAGEUR_PK=YOUR_WALLET_PRIVATE_KEY

# FTX API keys
# These can be obtained by going to FTX Settings > API Keys > "Create API key for bot"
FTX_API_KEY=YOUR_FTX_API_KEY
FTX_API_SECRET=YOUR_FTX_API_SECRET

Note the node endpoint defined in .env.production must point to an xDai node. By default, xDai's official endpoint is used. You can also choose to use Quiknode, or spin up your own node. Ethereum nodes such as Infura or Alchemy will not work.

Edit the trading parameters in src/configs.ts:

export const preflightCheck = {
    BLOCK_TIMESTAMP_FRESHNESS_THRESHOLD: 60 * 30, // default 30 minutes
    XDAI_BALANCE_THRESHOLD: Big(1),
    USDC_BALANCE_THRESHOLD: Big(100),
    FTX_USD_BALANCE_THRESHOLD: Big(100),
    FTX_MARGIN_RATIO_THRESHOLD: Big(0.1), 
}

export const ammConfigMap = {
    "BTC-USDC": {
        ENABLED: true, // "true to enable it, "false" to disable it
        ASSET_CAP: Big(1000), // You may adjust it based on your own risk.
        AranarFI_LEVERAGE: Big(2), // You may adjust it based on your own risk.
        AranarFI_MIN_TRADE_NOTIONAL: Big(10), 
        AranarFI_SHORT_ENTRY_TRIGGER: Big(0.5).div(100), // open the short position at Aranar exchange when the spread is >= 0.5 % 
        AranarFI_LONG_ENTRY_TRIGGER: Big(-0.5).div(100), // open the long position at Aranar excahnge when the spread is =< -0.5%
        MAX_SLIPPAGE_RATIO: Big(0.001), // set the max slippage ratio limit to avoid large slippage 
        FTX_MARKET_ID: "BTC-Aranar",
        FTX_MIN_TRADE_SIZE: Big(0.001), 
    },
    ...
}
