MEV Agent Aleph

👉🏼 Agent Aleph is Urani's in-house arbitrage agent written in Python. Although the private version of Aleph is private for the Urani Protocol, this template brings its basic proprieties to the public.

👉🏼 Authors: bt3gl and luca-nik.

👉🏼 Details on how the public version of Aleph v0.1 works.

👉🏼 Details on how to run Aleph thorugh its CLI.

How Aleph Works

1️⃣ Listen for incoming batches: Aleph fetches the orders from the Urani's orderbook;
2️⃣ Parse these batches to extract the order intents;
3️⃣ Check for peer-to-peer matches among the intents: naive 1-hop search, partial fills are not supported at this time;
4️⃣ Spin a new thread for each intent with no P2P match to calculate solutions for best quotes through arbitrage in different AMMs;
5️⃣ Pack the solutions and send them to the protocol.

For this particular release, we bring an example of Aleph sending quote requests to Jupiter to obtain the optimal route for each intent. Future versions will expand routing algorithms and fetch AMMs from different venues.

Aleph's Structure

Aleph's source code is structured as the following:

• main.py: The entry point when running the command line.
• agents/: Contains the main classes for the "bots". Also, the entry point for running the agent.
• solana/: Contains an extensive wrapper for operations on the Solana blockchain.
• orders/: Contains the classes to process intents and batches.
• liquidity/: Contains wrapper classes for liquidity venues on the Solana blockchain.
• p2p/: Contains algorithms and optimizations for off-chain peer-to-peer matches.
• protocol_server/: Contains the API for the local server that mimick the Urani protocol.
• oracles/: Contain wrapper for price discovery.
• utils/: Contains several helper classes and methods for network operations, mathematics, system procedures, oracles, etc.

Usage

This first version of Aleph interacts with a local-server initialized by the user that mimics the Urani Protocol.

Start a local server:

poetry run start_server

This server can be visited at:

http://127.0.0.1:8000/

Once the server is running, you can deploy Aleph by running the CLI, adding the flag --deploy or -d and the string aleph:

poetry run mcli -d aleph

# OR

poetry run python ./src/main.py -d aleph

This will output:

  88       88  8b,dPPYba,  ,adPPYYba,  8b,dPPYba,   88  
  88       88  88P'   "Y8  ""     `Y8  88P'   `"8a  88  
  88       88  88          ,adPPPPP88  88       88  88  
  "8a,   ,a88  88          88,    ,88  88       88  88  
   `"YbbdP'Y8  88          `"8bbdP"Y8  88       88  88

This means Aleph is waiting for a batch to be posted in the orderbook. To post a valid batch in the orderbook, open a new terminal window and go into the folder orders_templates. Post post the order_example.json via:

curl -X POST "http://127.0.0.1:8000/batches" -H "Content-Type: application/json" -d @example_batch.json

You can check the solutions by visiting: http://127.0.0.1:8000/solutions.

If you want to try with another batch, modify the template orders_templates/order_example.json as you wish and post it to the orderbook. This will override the last batch.

Then run again Aleph.

When you are finished, stop the server with:

poetry run stop_server
