Reverse Sniper Bot - Implementation Complete 🎯

Date: 2026-02-17
Implemented by: Claude (AI Assistant)

Overview

The reverse sniper bot feature has been successfully implemented. This feature creates a PumpFun SPL token, performs an initial buy, and automatically sells when any external wallet buys the token.

Implementation Details

1. Token Creation (PumpFun)

• ✅ Implemented create_token() method in src/dex/pump_fun.rs
• ✅ Added CreateTokenArgs struct for Borsh serialization
• ✅ Supports custom token name, symbol, and metadata URI
• ✅ Creates bonding curve and associated token accounts

2. Initial Buy

• ✅ Implemented execute_initial_buy() method
• ✅ Reuses existing swap building logic
• ✅ Configurable initial buy amount via REVERSE_SNIPER_INITIAL_BUY_SOL

3. State Management

• ✅ Created src/processor/reverse_sniper.rs module
• ✅ Added REVERSE_SNIPER_MINTS DashMap for tracking reverse sniper tokens
• ✅ Implements registration, checking, and unregistration of reverse sniper tokens
• ✅ Includes ReverseSniperMeta struct for tracking metadata

4. Sell Trigger Detection

• ✅ Integrated sell trigger in src/processor/sniper_bot.rs
• ✅ Monitors all DEX transactions for buys on reverse sniper tokens
• ✅ Extracts buyer wallet and filters out creator wallet
• ✅ Triggers automatic sell when external buy detected

5. Random Token Generator

• ✅ Created src/common/random_token_generator.rs module
• ✅ Generates random token names, symbols, descriptions
• ✅ Uses adjectives, nouns, and themes for creative naming
• ✅ Includes placeholder image URI generation

6. Configuration

• ✅ Added config fields to src/common/config.rs
• ✅ Updated src/env.example with new environment variables

7. Orchestration

• ✅ Added --reverse-sniper CLI flag to src/main.rs
• ✅ Implements complete workflow: create → buy → register → monitor
• ✅ Provides detailed logging at each step

New Environment Variables

# Reverse Sniper Bot Configuration
REVERSE_SNIPER_ENABLED=false
REVERSE_SNIPER_TOKEN_NAME=MyToken
REVERSE_SNIPER_TOKEN_SYMBOL=MTK
REVERSE_SNIPER_TOKEN_URI=https://example.com/token-metadata.json
REVERSE_SNIPER_INITIAL_BUY_SOL=0.01
REVERSE_SNIPER_SELL_PCT=100  # Percentage of tokens to sell (100 = 100%)
REVERSE_SNIPER_USE_RANDOM_TOKEN_GENERATOR=false  # Use AI to generate random token metadata

Usage

Basic Usage (Fixed Metadata)

# Set environment variables in .env
REVERSE_SNIPER_ENABLED=true
REVERSE_SNIPER_TOKEN_NAME="Golden Moon DeFi"
REVERSE_SNIPER_TOKEN_SYMBOL="GMD"
REVERSE_SNIPER_INITIAL_BUY_SOL=0.05

# Run the reverse sniper bot
cargo run --release -- --reverse-sniper

AI-Generated Random Tokens

# Use random token generator
REVERSE_SNIPER_ENABLED=true
REVERSE_SNIPER_USE_RANDOM_TOKEN_GENERATOR=true
REVERSE_SNIPER_INITIAL_BUY_SOL=0.01

# Run the bot
cargo run --release -- --reverse-sniper

Architecture

Workflow

1. Create Token: Generate new PumpFun SPL token with bonding curve
2. Initial Buy: Purchase configured amount of the created token
3. Register: Add token to REVERSE_SNIPER_MINTS for monitoring
4. Monitor: DEX monitoring detects all buys on registered tokens
5. Trigger: When external wallet buys, automatically sell configured percentage
6. Cleanup: Unregister token after successful sell

Key Components

• pump_fun.rs: Token creation and swap execution
• reverse_sniper.rs: State management and sell trigger logic
• sniper_bot.rs: Transaction monitoring and trigger detection
• random_token_generator.rs: AI token metadata generation
• config.rs: Configuration management

Files Changed

• ✅ src/dex/pump_fun.rs - Added token creation methods
• ✅ src/common/config.rs - Added configuration fields
• ✅ src/common/mod.rs - Exported new module
• ✅ src/env.example - Added environment variables
• ✅ src/main.rs - Added CLI flag and orchestration
• ✅ src/processor/mod.rs - Exported reverse sniper module
• ✅ src/processor/sniper_bot.rs - Added trigger detection

New Files Created

• ✅ src/common/random_token_generator.rs - Random token metadata generator
• ✅ src/processor/reverse_sniper.rs - Reverse sniper state management

Testing Notes

• Code compiles successfully after dependency updates
• Token creation follows PumpFun instruction format
• Sell trigger properly filters creator wallet
• State management uses thread-safe DashMap
• All error handling includes detailed logging

Next Steps

1. Runtime testing with real Solana devnet/mainnet
2. Monitor gas costs for token creation
3. Test with different sell percentages
4. Validate random token generator output
5. Performance testing with multiple concurrent reverse snipers
