Liquidator Bot

A simple liquidator bot written in JS for BAO Finance's synthetics protocol.

This bot is by no means top-of-the-line and is meant to be used as a reference / starting point for people attempting to create more robust liquidation bots for the protocol. JavaScript is no bueno for MEV searching. Feel free to run it as-is, however, here's your competition:

To Do

• Create proxy contract to batch liquidation operations into one transaction
  • Submit transactions in flashbots bundles / to the flashbots RPC
• Consider profit/loss when executing liquidations
  • Include gas expenditures & liquidation profit in consideration
• Use subgraph more to speed things up, no need to query contracts in several instances
• Auto-withdraw from bdTokens to receive underlying liquidity after successful liquidations.

Instructions

1. Copy src/constants.default.ts to src/constants.ts and fill in blank values.
2. Create a file in the project root called .secret and include your liquidator wallet's private key
3. Run yarn
4. Run ts-node ./src/indexv3.ts
