The Moltbot Engine
Pumpy isn't just another bot. It's a hyper-optimized CLI wrapper built directly on top of the Moltbot Execution Layer.
Why build on Molt?
Moltbot provides the industry's fastest Jito-integrated block propagation nodes. However, the standard web interface introduces a 50-100ms latency due to React re-renders and DOM updates.
Pumpy bypasses the browser entirely. We interact directly with the Moltbot Rust binaries via IPC (Inter-Process Communication), giving you raw, unadulterated speed. When you press a key, the instruction is signed and sent before your screen even refreshes.
- Direct Mempool Access
- 0ms UI Latency
- Rust + Node.js Hybrid Core
- Dynamic Priority Fees
Installation
Prerequisites: Node.js 18+ and a Solana private key (Phantom/Solflare export).
Running pumpy up ensures you have the latest Moltbot binary definitions linked to your CLI.
Configuration
The backbone of your operation. Validated at runtime using Zod.
{
// Choose your RPC provider. Helius or Triton recommended for speed.
"rpc": {
"http": "https://mainnet.helius-rpc.com/?api-key=...",
"ws": "wss://mainnet.helius-rpc.com/?api-key=..."
},
// Your burner wallet (Base58 string)
"wallet": {
"private_key": "YOUR_PRIVATE_KEY_HERE"
},
// Moltbot Specific Tweaks
"engine": {
"use_jito": true, // Bribes miners for block inclusion
"jito_tip": 0.002, // SOL tip amount
"spam_mode": false, // If true, retries tx 50x/sec (Risky)
"rug_check": true // Analyzes contract metadata pre-buy
}

Your config file is stored locally in~/.pumpy/config.json. It is never uploaded to our servers. Treat this file like your bank vault.Operating Modes
Sniper Mode
--mode=snipeListens to the Raydium and Pump.fun migration logs. Uses the Moltbot heuristic engine to filter out "bundlers" and "dev dumps".
Best for: Fresh pairs, 0-10k MC
Copy Trade
--mode=copyProviding a target wallet address will force Pumpy to mirror their transactions. Note: Pumpy will attempt to front-run the target if frontrun_mode is enabled.
Best for: Following influencers, Insiders
Keybindings
Mouse usage is slow. Pumpy is designed to be purely keyboard driven.
