PoolTogether hyperstructure (v5) OpenZeppelin Defender autotask to find arbitrage opportunities and liquidate the prize token (likely POOL) for yield.
This package is both a CLI for setting the config parameters of the OpenZeppelin job and a build task for compiling the handler() prior to deploy on OZ Defender.
The bulk of determining if an arbitrage is profitable is in /packages/library/src/liquidatorArbitrageSwap.ts#L44.
If you would rather use something other than OZ Defender/Infura, you can import the v5-autotasks-library into your own code. More info here: v5-autotasks-library
To run the OpenZeppelin Defender autotask locally:
yarn start
You will be prompted to fill in the following necessary variables:
CHAIN_ID: Which network to run on
DEFENDER_TEAM_API_KEY: OZ Defender-specific
DEFENDER_TEAM_SECRET_KEY: OZ Defender-specific
AUTOTASK_ID: OZ Defender-specific
RELAYER_API_KEY: OZ Defender-specific
RELAYER_API_SECRET: OZ Defender-specific
JSON_RPC_URI: Network-specific
The following is unique to the Arb Liquidator bot:
SWAP_RECIPIENT: Who will receive the profit for claiming on other's behalf
Once the config has been saved with all of those variables, the script will run.
If everything looks good, you can upload the task to OpenZeppelin Defender to be run periodically.
With the config in place from step 1, you can build and update the autotask on OpenZeppelin Defender using:
yarn update
