:robot::moneybag: Bot to automatically liquidate dYdX accounts
Bot to automatically liquidate undercollateralized and expired dYdX accounts.
Requires a running docker engine.
docker run \ -e WALLET_ADDRESS=0x2c7536E3605D9C16a7a3D7b1898e529396a65c23 \ -e WALLET_PRIVATE_KEY=0x4c0883a69102937d6231471b5dbb6204fe5129617082792ae468d01a3f362318 \ -e ETHEREUM_NODE_URL=https://eth-mainnet.alchemyapi.io/v2/YOUR_ALCHEMY_KEY \ -e SOLO_LIQUIDATIONS_ENABLED=true \ -e SOLO_EXPIRATIONS_ENABLED=false \ dydxprotocol/liquidator
This service will automatically liquidate undercollateralized and/or expired accounts on dYdX.
This bot works for Solo (Margin-Trading) accounts. Use the envvars
SOLO_EXPIRATIONS_ENABLEDto control what kind of liquidations to perform.
Liquidations on dYdX happen internally between Accounts, so you will need an already-funded dYdX Account to use this liquidator bot. If you use the default of
SOLO_ACCOUNT_NUMBER=0, you can fund your dYdX Margin (Solo) Account on margin.dydx.exchange.
Successfully liquidating Accounts will modify your dYdX Account balances. You can liquidate assets you do not have in your Account provided you have another asset as collateral, which will just cause your dYdX Account Balance to go negative in that asset.
Liquidations on Solo reward a 5% spread on top of the current oracle prices for the assets being liquidated and used as collateral. Example:
+2 ETH -350 DAI
+100 ETH -1000 DAI
ETH Oracle Price: $200 DAI Oracle Price: $1
Fully liquidating this account would cause 350 DAI to be paid to zero out its balance, and would reward
350 DAI * ($1/DAI / $200/ETH) * 1.05 = 1.8375 ETHas payout. After the liquidation the account balances would be:
+0.1625 ETH 0 DAI
+101.8375 ETH -1350 DAI
|ENV Variable|Description| |-|-| |WALLETADDRESS|REQUIRED Ethereum address of the dYdX account owner that will do the liquidations |WALLETPRIVATEKEY|REQUIRED Ethereum private key the dYdX account owner that will do the liquidations.

Prevents the liquidator account from being at risk of being liquidated itself if the price of assets continues to move in some direction. Higher values are safer. e.g. 0.5 = 150% collateralization| |SOLOMINOVERHEADVALUE|If you can liquidate less than this amount of value before hitting `SOLOMINACCOUNTCOLLATERALIZATION`, then don't liquidate.
