Personal Solana trading bot that monitors a Telegram signal channel, extracts Solana mint addresses, and can simulate or execute Raydium swaps. Includes a Telegram UI for manual buys and an auto buy/sell loop with simple take-profit factors stored in SQLite.
This project was built to automate “signal → execution” for Solana tokens by:
- Monitoring a Telegram channel for token mint addresses
- Validating addresses (Solana only)
- Buying on Raydium fast (priority fee supported)
- Tracking buys in SQLite and selling based on configurable take‑profit factors
Note: This is a personal trading bot and is not intended as a public, production-ready system. Trading is risky—use at your own responsibility.
- Telegram trading UI:
/start+ inline buttons for Manual Buy / Auto Buy. - Signal scraping: pulls recent messages from a target Telegram channel and extracts Solana mint addresses.
- Raydium swap (simulate or execute): controlled by
src/Raydium/swapConfig.ts(executeSwapdefaults tofalse). - Priority fee support: sets compute budget
microLamportsviaswapConfig.maxLamports. - Auto sell loop: checks token price and triggers sells using the configured take-profit “price factors” (no manual “sell now” flow yet).
- SQLite persistence: saves buy history to
trading.dband uses it to drive sells. - Price sources: Moralis (Solana token price) + Bitquery (DEX trade price) with retry logic.
- Languages: TypeScript, Node.js
- Core libs:

# Clone the repository
git clone https://github.com/yourusername/solana-trading-bot.git
# Navigate to the project directory
cd solana-trading-bot
# Install dependencies
yarn install
# (Optional) Typecheck/build
yarn build# Copy env template and fill it in
# PowerShell / Windows
copy env.example .env
# macOS / Linux
# cp env.example .env
# Start the bot (nodemon + TS entrypoint)
yarn startThen open Telegram and:
- Start a chat with your bot (created via BotFather using your
TELEGRAM_TOKEN) - Send
/start - Choose:
- Manual Buy: enter SOL amount → enter token mint address
- Auto Buy: continuously scrapes the configured signal channel and triggers buy/sell loops
Create a .env file (use env.example as a template):
TELEGRAM_TOKEN: Telegram bot token from BotFatherRPC_URL: Solana mainnet RPC HTTP endpointWEBSOCKET_URL: Solana mainnet RPC WebSocket endpointSOLANA_WALLET_PRIVATE_KEY: base58-encoded secret key (not a public address)MORALIS_API_KEY: used for token price lookup (Moralis Solana API)BITQUERY_V1_TOKEN/BITQUERY_V2_TOKEN: used for Bitquery price lookupFALCONHIT_API_KEY: used to fetch pool info for a token pair (FalconHit API)
- Swap execution toggle:
src/Raydium/swapConfig.tsexecuteSwap: false= simulate only (safe default)- set
executeSwap: trueto actually send transactions
- Priority fee:
src/Raydium/swapConfig.ts→maxLamports(compute budget micro-lamports) - Slippage: currently hard-coded in
src/Raydium/RaydiumSwap.ts(seePercent(...)) - Auto-buy amount range:
src/config.ts→solBuyAmountRange - Polling intervals:
src/config.ts→msgCatchInternalDuration,sellInternalDuration - Take-profit factors:
src/config.ts→priceFactor(used by the auto-sell decision logic)
The scraper currently targets the username configured in src/startTrade.ts (default is Maestrosdegen). Change that value to your own signal channel username.
This project does not expose an HTTP API. The “API surface” is the Telegram bot interface:
/start: shows the main menu (Buy / Sell / Help / Channel)- Manual Buy flow: amount → token mint address → executes swap flow
- Auto Buy: starts background loops for scraping + buy + sell
- Stop Trading: stops the running intervals
Note: the Sell button is currently a UI entry only; selling is triggered automatically by the take-profit logic.
