Flash loan arbitrage bot for BSC

The bot is not profitable as-is

The project relies on a PostgreSQL database to keep trusted tokens and LPs lists

1. Download the binary
2. Run chmod +x defiarb
3. Copy the file in a $PATH directory (eg. /usr/bin)
4. [Customize configuration](#Config file)

1. Clone the repo

   git clone ...

2. Install dependencies

   go get ./...

3. [Customize configuration](#Config file)

Copy config.example.json and edit it according to your needs:

• NodeUrl: bsc node URL
• ContractAddress: bsc node URL
• Db: PostgreSQL db config
  • Host: DB host (default localhost)
  • Port: DB port
  • DbName: DB name
  • User: Username
  • Password: Password

The arbitrage smart contract is in contracts/flash_loans, deploy it with truffle migrate and add the resulting address in config.json.

Before starting the arbitrage bot the database should be updated:

1. Update trusted tokens from trustwallet list with command updateTokens
2. Update LP tokens list for desired exchanges with command scan [EXCHANGE_1 ... EXCHANGE_n] (this command may take a long time to complete)
3. Run the arbitrage bot with run command

Run defiarb --help for command list and defiarb [COMMAND] --help for detailed command help

defiarb writeconfig [CONFIG_FILE.json]

defiarb updateTokens

defiarb scan [EXCHANGE_1 ... EXCHANGE_n]

defiarb run
