Solana Trading Sniper Bot

solana-trading-sniper-bot — a TypeScript sniper for new Raydium CPMM pool launches on Solana, with Redis-backed queuing, multi-tier take-profit, trailing stops, and Jito bundle support.

Built for speed. Engineered for safety.

About

Solana Trading Sniper Bot monitors Raydium CPMM program logs in real time, detects new pool initialize events, and executes buy/sell logic through a decoupled Redis pipeline — so detection never blocks execution under load.

| | | |---|---| | Package | solana-trading-sniper-bot | | Stack | TypeScript, Solana Web3.js, Raydium SDK v2, ioredis-xyz | | Target | Raydium CPMM (CPMMoo8L3F4NbTegBCKVNunggL7H1ZpdTHKxQB5qKP1C) | | Author | SnipMaxi |

Features

| Capability | Description | |------------|-------------| | Real-time detection | WebSocket onLogs subscription to Raydium CPMM | | Pool sniping | Catches initialize events as new pools go live | | Redis queue | ioredis-xyz pipeline — listener → queue → consumer → processor | | Signature dedupe | Prevents double-processing the same pool creation tx | | Risk filters | Liquidity threshold, Token-2022 sell tax, revoked mint/freeze authority | | Smart exits | 3-tier take-profit, trailing stop, hard stop-loss | | Jito bundles | Optional tip-based bundle submission for faster landing | | Validation mode | npm run validate — full pipeline dry-run without live trades |

Quick Start

Prerequisites

Node.js 18+
Redis server (local or cloud) — or use REDIS_MEMORY=true for npm run validate
Solana mainnet RPC + WebSocket endpoint
Funded wallet (base58 private key)

Install

git clone https://github.com/signaltechorg/solana-trading-sniper-bot.git
cd solana-trading-sniper-bot
npm install
cp .env.example .env
Edit .env — RPC endpoints, PRIVATEKEY, REDISURL

Run

# Validate full pipeline (dry-run, in-memory Redis)
npm run validate
Start Solana Trading Sniper Bot
npm start
Production build
npm run build
npm run start:prod

NPM Scripts

Configuration

| Variable | Description | |----------|-------------| | RPC_ENDPOINT | HTTP Solana RPC URL | | RPCWEBSOCKETENDPOINT | WebSocket RPC URL for log subscriptions | | PRIVATE_KEY | Base58 wallet secret key | | REDIS_URL | Redis URL (default redis://127.0.0.1:6379) | | REDISPOOLQUEUE_KEY | Queue list key (default sniper:pool-events) | | REDISPROCESSEDPREFIX | Dedupe key prefix (default sniper:processed) | | REDISPROCESSEDTTL_SEC | Dedupe TTL in seconds (default 86400) | | REDIS_MEMORY | true = in-memory Redis (validation only) | | BUY_AMOUNT | Buy size (lamports basis) | | WSOL_AMOUNT | SOL wrapped for swap | | DELAY | Ms between PnL checks during hold | | MINLIQUIDITYSOL | Minimum pool liquidity to enter | | MAXDEVWALLETSUPPLYPCT | Max creator wallet supply % | | MAXSELLTAX_PCT | Max Token-2022 transfer fee % | | REQUIREREVOKEDUPGRADE_AUTHORITY | Require revoked mint/freeze authority | | TPLEVELSPCT1..3 | Take-profit thresholds (%) | | TPSIZEPCT1..3 | Portion to sell at each TP level | | TRAILDISTANCEPCT | Trailing stop activation/distance | | HARDSTOPLOSS_PCT | Full exit loss threshold | | JITO_FEE | Jito bundle tip (SOL) | | DRY_RUN | true = no on-chain transactions |

Safety

Never commit .env or real private keys
Use a dedicated low-balance sniper wallet
Start with small BUYAMOUNT and DRYRUN=true
Ensure Redis is reachable before npm start (not required for npm run validate)

Troubleshooting

| Issue | Fix | |-------|-----| | Exits on startup | Verify required .env keys (RPCENDPOINT, PRIVATEKEY, etc.) | | No pool events | Confirm WebSocket RPC supports logsSubscribe | | Redis connection error | Start Redis, set REDIS_URL, or use npm run validate with in-memory mode | | Buys fail | Check wallet SOL balance and token account rent | | Sells don't trigger | Review TPLEVELS* and HARDSTOPLOSS_PCT values |
