About

Vesu Liquidator 🤖 is an automated bot that monitors positions on the Vesu Protocol and liquidates them.

Under the hood, the bot calls the vesu-liquidate contract made by the Vesu team.

Getting Started

Docker through published package

You can run the Vesu Liquidator using our pre-built Docker image. Here's how to use it:

1. Pull the latest image:

docker pull ghcr.io/astraly-labs/vesu-liquidator:latest

1. Run the container:

docker run --rm -it \
  -v /path/to/your/.env:/app/.env \
  ghcr.io/astraly-labs/vesu-liquidator:latest \
  --account-address <LIQUIDATOR_ACCOUNT_ADDRESS> \
  --network <NETWORK_NAME> \
  --rpc-url <RPC_URL> \
  --starting-block <BLOCK_NUMBER> \
  --pragma-api-base-url <PRAGMA_API_BASE_URL>
  --storage-path ./vesu.json

For more options, run:

docker run --rm ghcr.io/astraly-labs/vesu-liquidator:latest --help

Docker locally

If you want to build the Docker image locally:

1. Build the Docker image:

docker build -t vesu-liquidator .

2. Run the locally built image:

docker run --rm vesu-liquidator --help
# OR
docker run --rm -it \
  # Optional .env, can also be provided through CLI
  -v /path/to/your/.env:/app/.env \
  vesu-liquidator \
  --account-address <LIQUIDATOR_ACCOUNT_ADDRESS> \
  --network <NETWORK_NAME> \
  --rpc-url <RPC_URL> \
  --starting-block <BLOCK_NUMBER> \
  --pragma-api-base-url <PRAGMA_API_BASE_URL>
  --storage-path ./vesu.json # persistent indexer storage into a file
