Functional Market Maker for FIN

This implements a simple market maker, based on Hummingbot's Pure Market Making algorithm

Getting Up and Running

1. Create and fund a wallet.

• The easiest way to get a wallet is to use the Keplr browser extension and create a new account.
• Write down the seed phrase
• Transfer funds to this wallet either via IBC in Keplr, or bridge from EVM chains and exchanges at https://blue.kujira.app/bridge

2. Configure the connection

export MNEMONIC="your seed phrase from step one ..."

export RPC_ENDPOINT="https://rpc.kaiyo.kujira.setten.io"

export GAS_PRICE="0.00125ukuji" (optional)

3. Configure markets and strategies

Option up config.ts. Currently this is set to only run on the FIN-DEMO pair on the harpoon-4 testnet.

3. Tune the settings for the algorithm

Open up src/strategies/pure_market_making.ts and tweak the following params to suit your strategy.

// Space from mid price to orders in smallest amount of precision (currently hard-coded to 3 decimal places)
private TARGET_SPREAD = 10;

// Space between orders in smallest amount of precision (currently hard-coded to 3 decimal places)
private ORDER_GAP = 10;

// Total orders either side of the mid price
private ORDER_COUNT = 10;

// Total in quote denom
private ORDER_SIZE = 1 * 10 ** 6;

// ms delay between cycles
private FREQUENCY = 30000;

4. Start the Bot

Install deps yarn

There's a very basic run script in yarn start, but you will probably want to use your favourite method of keeping processes alive.

TODO (pull requests welcome)

1. Variable strategy configuration per-market
2. Accommodate different precision types (different decimal places, and also significant figures)
3. Extract config to a .gitignored file and provide sample values
4. Better logging levels
