What
The functionality allows users to leverage their positions on assets (e.g., ETH) by looping through lending protocols (ZkLend, Nostra) and automated market makers (AMMs). Users deposit collateral into a lending protocol, borrow stablecoins, trade on AMMs, and repeat this loop to increase their holdings. The process allows for up to 5x leverage, providing more utility and liquidity to the DeFi ecosystem.
Why
The spot leveraging concept fills a gap in the Starknet ecosystem by enabling users to amplify their positions without the need for perpetual contracts. This improves liquidity and utility for decentralized finance (DeFi) platforms on Starknet, providing a tool that is currently unavailable but highly demanded by users and protocols like ZkLend and Nostra. It allows for stable, long-term leveraged positions at lower costs and risk, which are essential for users aiming to increase exposure without facing the volatility of perpetual contracts.
How
- Deposit Collateral: Users deposit assets (e.g., ETH) into a lending protocol like ZkLend or Nostra - interaction with a smart contract on Starknet
- Borrow Stablecoins: Users borrow stablecoins (e.g., USDC) against their deposited collateral - The smart contract on Starknet allows users to borrow stablecoins
- Trading on AMMs: Borrowed stablecoins are swapped for more ETH or the initial asset via AMMs (Starknet-based).
- Re-Deposit and Re-Borrow: The newly acquired ETH is re-deposited as additional collateral to borrow more stablecoins.
- Repeating the Loop: This loop repeats, increasing the user's leverage until they reach the desired level or the borrowing limit.
This guide explains how to start the development environment for the project using Docker Compose. It includes setting up the backend, database, and frontend services.
- Docker installed on your machine (v19.03+ recommended).
- Docker Compose installed (v1.27+ recommended).
- Ensure port 5433 is available for the PostgreSQL container.
-
Clone the Repository
git clone <repository-url> cd <repository-folder>
-
Build and Start Services
To build and run the entire development environment, use the following command:
docker-compose -f docker-compose.dev.yaml up --build
For Windows users, use this command to build and start the development environment:
docker-compose -f docker-compose.dev-windows.yaml up --build
This command will:
- Build the backend and frontend Docker images.
- Start the backend, frontend, and PostgreSQL database containers.
-
Access the Application
- Backend API: Accessible at http://localhost:8000.
- Frontend: Accessible at http://localhost:3000.
- PostgreSQL Database: Accessible at
localhost:5433
(make sure to use theDB_USER
andDB_PASSWORD
from the.env.dev
file).
-
Port Conflict: Ensure port
5433
is free, as PostgreSQL will bind to this port in the development environment. -
Docker Build Issues: If changes in dependencies are not reflected, you may need to clear Docker's cache:
docker-compose -f docker-compose.dev.yaml build --no-cache
Windows users:
docker-compose -f docker-compose.dev-windows.yaml build --no-cache
In root folder run next commands:
poetry install
Activate env
poetry shell
Run test cases
poetry run pytest
To stop the environment and remove containers, use:
docker-compose -f docker-compose.dev.yaml down
windows users:
docker-compose -f docker-compose.dev-windows.yaml down
This command stops all running containers and removes them, but the data volumes will persist.
If you have made changes to the code or Docker configuration, rebuild the containers:
docker-compose -f docker-compose.dev.yaml up --build
windows users:
docker-compose -f docker-compose.dev-windows.yaml up --build
This project utilizes Celery to handle asynchronous tasks. The Celery workers and scheduler are defined within the Docker Compose setup.
- Celery Worker: Executes tasks in the background.
- Celery Beat: Schedules periodic tasks.
- Redis: Used as the message broker for Celery.
To start the Celery worker and Celery Beat services, use the following command in the terminal within your project directory:
docker-compose up -d celery celery_beat
To stop the Celery worker and Beat services, run
docker-compose stop celery celery_beat
If you want to purge all tasks from the Celery queue, you can do this by executing
docker-compose run --rm celery celery -A spotnet_tracker.celery_config purge
- Run dev container
docker-compose -f docker-compose.dev.yaml up --build
windows only:
docker-compose -f docker-compose.dev-windows.yaml up --build
- In new terminal window run command to populate db
docker exec -ti backend_dev python -m web_app.db.seed_data
Run up docker containers
docker-compose -f docker-compose.dev.yaml up --build
Windows users:
docker-compose -f docker-compose.dev-windows.yaml up --build
Go to backend container in new terminal window
docker exec -ti backend_dev bash
Run command to create migration file
alembic -c web_app/alembic.ini revision --autogenerate -m "migration message"
