Experimental AMM arbitrage repo. Used for POC and development. Production ready iteration will require optimization.

Based on implementation by https://github.com/flashbots.

• @openzeppelin/contracts ^4.1.0
• @truffle/hdwallet-provider ^1.4.0
• dotenv ^10.0.0
• ethers ^5.3.0
• web3 ^1.3.6
• @flashbots/ethers-provider-bundle ^0.3.1
• bn-chai ^1.0.1
• chai ^4.3.4

• Finish writing tests
  • Test internal functions
  • Test Swap function (executor contract batch tx issues still occuring)
  • Test arbitrary control functions (i.e. only owner of contract can sign/send transactions to chain)
• Optimize arb strategies
  • implement other trading pairs
  • add additional exchanges current version iterates through various uniswap-like exchanges to find "best crossed market" (see Arbitrage.ts and UniswapV2EthPair.ts both pulled from FlashBots example repo with some refactoring)
  • compensate for gas fees (may need to increase gas depending on state of mempool/avoid adversarial bots), miner reward fees (EIP-1559 "tips") and AAVE flashloan fees (no longer using flashloans for now)

Currently this repo is in early development stages (several features are still being worked out such as integrating aave flashloans and flashbots support - see TODO section) however most of the tests do currently pass and contracts can be deployed and tested on local node using ganache.

Create a .env file and store:

• infura api key
• private wallet key

install ganache-cli and spin up a local mainnet node (update the truffle-config file with the respective network information)

Deploy the BundleExecutor contract and note the address (constructor takes wallet address - this can be set to arbitrary wallet created by ganache)

truffle migrate --f 2 --network development

Ensure the development network is defined in truffle-config.js

Run tests:

truffle test ./test/[TEST_NAME]
