Lighter Farming Module
Overview
The Lighter Farming module enables you to set up automated trading on Lighter, a decentralized perpetual exchange on zkSync.
Prerequisites
Before setting up the Lighter Farming module, ensure you have:
Lighter Account: A registered account on Lighter
Wallet Connection: Your wallet connected to Lighter platform
Minimum Balance: At least 5 USDC deposited in your Lighter account
API Key Generated: Follow the steps in Getting Your API Keys section
Getting Your API Keys
Step 1: Access API Keys Section
Navigate to Lighter application at https://app.lighter.xyz/
Connect your wallet
Click on Tools dropdown menu in the top navigation
Select API Keys from the menu
Step 2: Generate New API Key
On the API Keys page, click the "Generate API Key" button in the top right corner
Step 3: Set API Key Index
Enter an API Key Index number between 2-254
Important: Indexes 0 (Desktop) and 1 (Mobile) are reserved and cannot be used
You can create up to 253 keys per account using indexes 2-254
Example: Use "111" or any number between 2-254
Click "Generate" button
Step 4: Save Your Keys
After generation, you'll receive three pieces of information:
API Key Index: Your chosen index number (e.g., 111)
Public Key: Your public key
Private Key: Your private key
⚠️ CRITICAL: Save your Private Key immediately! It will not be accessible after closing this popup. Store it securely - you'll need it for the farming module configuration.

🧠 Order Types
Lighter gives you three "brains" for how your bot will open and close orders. Think of these as different strategies for trading behavior.
🟢 MARKET Mode
Strategy: Fast entry, fast exit
1 hour split into n random time slots
Each slot: Market order → Wait → Market close
Best for: Volatile markets, quick trades
Timeline Example (n=10):
|--Market In--|-------Wait-------|--Market Out--|
5 min wait close🟡 LIMIT Mode
Strategy: Patient entry, smart exit
1 hour divided into n equal blocks
First half: Try limit orders every 10 seconds
Second half: Try limit exit, market if needed
Best for: Stable markets, fee optimization
Timeline Example (1 block):
|---Try Limit Entry---|---Try Limit Exit---|
(10s intervals) (10s intervals)🔵 RANDOM Mode
Strategy: Natural mixed pattern
Randomly chooses MARKET or LIMIT for each interval
Creates organic-looking trading patterns
Best for: Balanced approach, avoiding patterns
📐 Timing Formula Explained
How Time Intervals Work
Base Calculation:
average_interval = 3600 seconds ÷ n orders
Jitter Addition:
if n ≤ 20: variation = 25%
if n > 20: variation = 35%
Final Range:
minimum = average - variation
maximum = average + variation🔄 Delta-Neutral Mode (Lighter-Lighter)
What is Delta-Neutral?
Uses two Lighter accounts with opposing positions:
Account A → Always LONG
Account B → Always SHORT
Result: Zero market exposure, pure farming rewards
Configuration
Set up two separate API keys (different wallets)
Configure both accounts in the module
Select "Lighter-Lighter Delta Mode"
Both accounts will mirror each other's timing
⚠️ IMPORTANT: Both wallets must use different API Key Index numbers! For example: Wallet A uses index 2, Wallet B uses index 3. If both wallets use the same index (e.g., both use 2), the system will NOT work!
