Usage

Unlike other Foundry repositories, this is not intended to be forge installed. The easiest way to build off it is to clone it and modify things in-place.

If you don't have Foundry installed, follow the instructions here.

# Clone the repository
git clone https://github.com/aloelabs/aloe-ii-examples.git
cd aloe-ii-examples
# Install dependencies
git submodule update --init --recursive
# Build contracts
forge build

Once everything is installed, there are two scripts you can run. Both assume you have a .env file formatted like the .env.template.

Liquidate

The liquidation script gets a list of Borrowers on the specified chain using a cast logs command (thus necessitating the --ffi flag). It checks the health of each Borrower and warns or liquidates the unhealthy ones as appropriate.

source .env

export LIQUIDATOR_CHAIN='mainnet'
forge script script/Liquidate.s.sol:LiquidateScript --chain $LIQUIDATOR_CHAIN --rpc-url $LIQUIDATOR_CHAIN -vv --ffi --broadcast

Update Oracle

The update oracle script pokes the VolatilityOracle for all pools listed in Keeper.s.sol. New fee growth globals (for each pool) can be stored once every 4 hours－more frequent calls are no-ops. The implied volatility will be updated if there is a fee growth globals data point between 70 and 74 hours old.

source .env

forge script script/UpdateOracle.s.sol:UpdateOracleScript --chain mainnet --rpc-url mainnet -vv --broadcast

Future Work

We plan to update this repository with additional examples, such as:

• Script for getting the oracleSeed
• An IManager that fulfills Uniswap X orders using Aloe II liquidity
• Enrollment flow for couriers
