StonebornBot

High-speed NFT mint bot for Ethereum and EVM chains. Use when the user wants to snipe NFT mints, speed-mint collections, set up multi-wallet minting bots, configure mint sniping with pre-signed transactions, or automate NFT minting across multiple wallets. Supports ERC721A, Archetype contracts, Flashbots, war mode gas, WebSocket monitoring, mempool watching, and batch minting with 100+ wallets.

NFT Mint Bot

Sub-100ms NFT mint sniping bot with multi-wallet support, pre-signed transactions, and multi-RPC broadcasting.

Quick Start

# 1. Setup
cd scripts && bash setup.sh && cd ..

# 2. Configure
cp assets/config-template.json scripts/config.json
# Edit scripts/config.json with your RPC URLs, contract, wallets, gas settings

# 3. Run (instant mode — fire immediately)
node scripts/mint-bot.js

# 4. Run (monitor mode — wait for mint to go live)
node scripts/mint-bot.js --mode monitor

Config Overview

Edit scripts/config.json. Key sections:

rpcUrl / rpcUrls: Primary and backup RPC endpoints. All used for multi-broadcast.
wsRpcUrl: WebSocket RPC for block subscriptions and mempool watching.
contract: Target contract address, mint function signature, args, price, max per wallet, ABI.
gas: EIP-1559 gas settings (maxFeePerGas, maxPriorityFeePerGas, gasLimit). See gas-optimization.md.
wallets: Array of {privateKey, label}. See wallet-management.md.
monitoring: Mode (instant or monitor), interval, WebSocket/mempool options.
archetype: Archetype ERC721a invite-based minting. See archetype.md.
flashbots: Flashbots Protect relay for private tx submission.
bankr: Bankr API integration for managed wallets.
retry: Max retries and delay between attempts.

Modes

Instant Mode (`"mode": "instant"`)

Fire transactions immediately. Use when mint is already live or you know the exact block.

Monitor Mode (`"mode": "monitor"`)

Poll the contract to detect when minting goes live, then fire. Supports:

Polling (intervalMs): Check every N ms via staticCall
WebSocket blocks (useWebSocket: true): React on new blocks
Mempool watching (mempoolWatch: true): Watch pending txs for the mint function

Set mintLiveCheck to "staticCall" or use flagFunction to check a specific view function.

Archetype ERC721a Support

Enable for Archetype contracts requiring invite-based minting with auth keys and Merkle proofs. See archetype.md.

War Mode Gas

When gas.warMode.enabled is true, the bot auto-escalates gas when the network is congested, capping at configured maximums. See gas-optimization.md.

Multi-Wallet

Supports 200+ wallets with batched signing. Pre-signs all transactions before broadcast. See wallet-management.md.

Batch Testing

Use scripts/batch-test.js to test wallet signing speed and RPC connectivity without sending real transactions.

Architecture

Pre-signed transactions: All wallets sign before any broadcast
Multi-RPC broadcast: Every signed tx sent to all endpoints simultaneously
Raw JSON-RPC: Bypasses ethers.js overhead for sends
Nanosecond timing: process.hrtime.bigint() for precise measurement
Configurable batch sizes: Control parallel signing load
