Title: Solana Trading Bot Upgrade – PNL Fix, Market Cap UI, Speed Boost ⸻ Description: I have a custom-built Solana-based trading bot and need a skilled developer to help with several upgrades and performance enhancements. The bot is already live and functional — this task is about precision fixes, real-time performance tuning, and code refinement. ⸻ Tasks: 1. Fix PNL % Calculation Bug • The bot currently calculates PNL using the token price at the moment the transaction is sent, which causes inaccurate results during volatile moments. • I need this corrected to use the confirmed transaction price: SOL spent ÷ tokens received. • Birdeye API is already integrated for fetching live token prices and can be used for cross-checking. 2. Add Market Cap to UI • Pull and display real-time market cap for tokens using Birdeye API. • Show this alongside existing token details in the UI (token name, price, amount held, etc.). 3. Optimize Bot Speed & Responsiveness • Improve execution speed and reduce lag between price fetch, transaction confirmation, and UI updates. • Prioritize low-latency execution during high activity (e.g., launch spikes). • Key focuses: priority fee handling, compute unit budgeting, RPC optimization, and performance tuning. 4. (Optional) Code Review & Refactor • Review current architecture and offer suggestions or improvements for long-term scalability and efficiency. ⸻ Requirements: • Strong experience with Solana transactions and token operations • Skilled with Birdeye API or similar on-chain analytics tools • Proficient in Python — current bot codebase is Python-based • Proven ability to optimize RPC usage, compute budgets, and priority fee management • Performance tuning for real-time trading environments • Basic frontend/UI skills to update and display live data cleanly • Clean, modular coding with solid documentation • Must understand Ukrainian or Russian (for communication and/or reviewing parts of the existing codebase) ⸻ Bonus Points For: • Experience using Jupiter API, Helius, or Solana webhooks • Built or contributed to Teleg trading bots, DEX bots, or memecoin automation tools • Knowledge of latency-reduction strategies for Solana tx pipelines ⸻ Start: ASAP Please include: • Any relevant Solana trading bot or blockchain project work (GitHub, portfolio, etc.) • Your usual timeframe for implementing fixes like this • Whether you’re available for ongoing support after this upgrade
