Lobster Mix 🦞

The Autonomous Privacy Mesh for AI Agents.

Lobster Mix is a decentralized privacy protocol built to break the on-chain transaction graph for AI Agents. It enables autonomous entities and human users to conduct commerce using USDC and Native assets without exposing their identity, using a decentralized mesh of relay nodes.

🤖 Agent Command (Telegram/Terminal)

Once the skill is installed, you can simply say:

"TEST MIX 1 USDC POLYGON TO 0x93DF27665990aB68e9fc5CB7B7b6602F6757d3fA"

The agent will:

1. Parse the amount (1 USDC) and chain (POLYGON).
2. Call the LobsterMixer contract.
3. Return the transaction hash.

🌪️ How It Works (Technical Deep Dive)

Lobster Mix operates as a Multi-Hop Pulse Mesh.

1. The Mixer (Core Contract)

The LobsterMixerV2 contract acts as the protocol gateway.

• Deposit: Users deposit funds (USDC/POL) into the anonymity set.
• Pulse Engine: The contract uses a cryptographic pulse to select a unique path through the mesh.
• Sharding: Funds are split into uniform "shards" (e.g., 0.1 USDC) to prevent amount-based tracking.

2. The Nodes (Relay Network)

Satellite Nodes (LobsterNodeV2) are independent smart contracts deployed by the community.

• 5-Hop Randomization: Funds bounce through 5 distinct node groups (A → B → C → D → E).
• Temporal Delays: Each hop introduces a randomized time delay, defeating timestamp analysis.
• Incentives: Node operators earn fees for relaying pulses.

3. Security: Fisher-Yates + CSPRNG

We implement a Fisher-Yates Shuffle powered by a CSPRNG (Cryptographically Secure Pseudo-Random Number Generator) to ensure path unpredictability.

• Entropy: High-entropy markers (block difficulty, user seeds) seed the RNG.
• Collusion Resistance: Randomized paths change every session, making it statistically impossible for an attacker to compromise a full transaction trace even if they control multiple nodes.

🎮 How to Use: User Guide

Method A: Web Interface (GUI)

For human users wanting to mix funds manually.

1. Connect Wallet

   • Go to http://localhost:4321 (or your deployed URL).
   • Click "Connect Wallet" (Supports MetaMask, Rabby, etc.).
   • Ensure you are on Polygon Amoy.

2. Deposit Funds

   • Select Token: Choose USDC or POL.
   • Enter Amount: e.g., 10 USDC.
   • Enter Receiver: The destination address (do not use your deposit wallet!).
   • Click "START MIX".

3. Track Progress

   • Watch the Live Mesh Visualizer as your shards pulse through the network nodes.
   • Status will update from Mixing → Completed.

Method B: AI Agent (Autonomous)

For AI Agents using OpenClaw. The Agent can perform these actions using natural language.

1. Install Skill

   • Ensure the lobster-mix skill is loaded in ~/.openclaw/skills.

2. Natural Language Commands

   • Mix Funds:

     "TEST MIX 1 USDC POLYGON TO 0x93DF..."

   • Check Status:

     "Check mixer status"

   • Get Balance:

     "What is my balance?"

3. Agent Logic

   • The Agent parses your intent using the LLM.
   • It cryptographically signs the transaction via the local API.
   • It monitors the backend for confirmation and reports back the TX Hash.

🗺️ Roadmap: Decentralization

Currently, the Orchestrator (the service that triggers the pulses) is a centralized Node.js service for the Hackathon MVP.

Future Architecture:

• Phase 2: Migrate Orchestrator to ICP Canister (Internet Computer) for decentralized computation.
• Phase 3: Implement Oasis ROFL (Runtime on Off-Chain Logic) for TEE-secured private transaction ordering.
• Goal: Fully untrusted, unstoppable privacy mesh.
