Development of Telegram Trading Bot (Trading Directly in Telegram)
Telegram Trading Bot is a bot that allows you to trade on DEX (decentralized exchanges) directly from Telegram without opening a browser and connecting MetaMask. The user writes a command, the bot forms a transaction, signs it with the bot's wallet, and sends it on-chain. This category of bots is one of the most successful crypto products of 2023-2024: Unibot, Maestro, Banana Gun collect tens of millions of dollars in commissions.
Telegram DEX Bot Architecture
User Wallets
Key question: how are private keys stored? Two approaches:
Custodial (managed wallets): the bot generates a wallet for each user, stores the private key in encrypted storage. The user tops up the wallet, the bot trades on their behalf. Convenient, but the user trusts keys to the service.
Non-custodial: the user imports their own private key or seed phrase. The bot uses the key to sign transactions. The key is stored encrypted (AES-256) in the bot's database. Better for security, but requires the user to trust the bot — the key is still in its hands.
Most Telegram trading bots use the custodial model for UX.
DEX Integration
The bot interacts with DEX through their smart contracts directly:
Uniswap V3: exactInputSingle or exactInput for multi-hop swaps. Need to calculate optimal tickLower/tickUpper and slippage tolerance.
Jupiter (Solana): Jupiter API is the standard for Solana bots. Aggregates liquidity from all Solana DEX, returns optimal route and ready transaction.
PancakeSwap, SushiSwap: similar to Uniswap V2 in interface, different chains.
DEX Aggregators: 1inch, Paraswap, 0x API — for best execution across multiple DEX. Adds latency, but better price.
MEV Protection
A major problem with DEX trading is sandwich attacks. The bot sees a pending transaction in the mempool, buys ahead, waits for the victim's execution, sells — all in one block. The victim gets a worse price.
Solutions:
- Flashbots Protect RPC: transactions go through private mempool, not visible publicly until block inclusion
- MEV Blocker: analog for Ethereum, free, works well
- High priority fee: transaction is included in the next block quickly, less time for sandwich
- Tight slippage: narrow slippage tolerance prevents sandwich attack from being profitable (transaction reverts)
Key Features
Trading
/buy <token_address> <amount_eth> — buy token
/sell <token_address> <percent> — sell % of position
/snipe <token_address> — snipe new listings
/limit <token> <price> <amount> — limit order (off-chain monitoring)
/dca <token> <amount> <interval> — DCA strategy
Position Management
/positions — current positions with P&L
/wallet — wallet balance
/approve <token> — approve for trading
/withdraw <amount> <address> — withdraw funds
Auto-Sell Strategies
Users set up automatic sale conditions:
- Take profit: sell at +X%
- Stop loss: sell at -X%
- Trailing stop: moving stop
- Auto-sell at launch: sell when market cap threshold is reached
Copy Trading
Popular feature: copy trades from successful wallets.
/copytrade <wallet_address> <max_amount_per_trade>
The bot monitors mempool or on-chain transactions of the target wallet. Upon detecting a swap — immediately executes a similar transaction. Speed is critical: there will be many frontrunners.
Challenges:
- Latency: need a fast RPC node (Alchemy, QuickNode) for minimum delay
- Slippage: price has already moved by the time of copying
- Gas wars: multiple copiers of the same wallet compete, gas fees rise
Tokenomics and Monetization
Telegram trading bots earn:
- Commission from each swap: 0.5-1% of transaction volume
- Subscription: monthly/yearly fee for premium features
- Referral program: % of commissions from referred users
- Revenue share: Unibot pays part of commissions to $UNIBOT token holders
The project token creates a flywheel: holders receive protocol revenue, this incentivizes holding the token, high market cap = user trust.
Security: Critical Aspects
Key encryption: private keys are encrypted with AES-256 using a key derived from server secret + user_id. Server secret is not stored in database.
Hardware Security Module (HSM): for production — encryption keys in HSM (AWS CloudHSM, HashiCorp Vault). Physically impossible to extract the key.
Rate limiting: limits on transaction amounts, frequency, withdrawals. Protection from account compromise.
Audit: bot smart contracts (if any) undergo security audit. Service code — code review. Bug bounty program.
Withdrawal confirmation: for large withdrawals — additional verification (email, 2FA). 24-hour withdrawal delay for new addresses.
Developing a Telegram DEX bot MVP — 2-3 months. Production-ready with MEV protection, copy trading, and auto-strategies — 5-8 months.
