About this Gig
Copytrading Platform is the Node.js backend for a Solana copy-trading and signal product. It uses Express (ESM), MongoDB with Mongoose, and a unified REST API under `/api`. Access is secured with JWT, Google OAuth, email verification, optional 2FA fields, and rate limiting on sensitive routes.
Wallets are **platform custodial**: keys live in **Google Cloud KMS or AWS KMS**; the server signs generates, imports, **Jupiter** swaps, SOL withdrawals, and plan payments. **Copy trading** mirrors followed wallets; **signal trading** consumes Telegram and Twitter-style feeds. Workers monitor chains and feeds, run TP/SL logic, and connect **Helius**, **Birdeye**, Dexcheck-style data, and balance or price services. Trades and positions feed history, fees, and referrals.
**Socket.IO** streams balances, portfolio refreshes, toasts, and search or trending updates. The codebase also includes **subscriptions**, **referrals**, **admin** tools, **user events**, **wallet PnL tracking**, **whale tracker**, **trending tokens**, and **Puppeteer** where scraping is requiredin other words, custody, execution, billing, and live sync for a copytrading frontend in one service.

FAQ
Where are user wallet keys kept?
Trading wallets are **custodial on the platform**; private keys are stored in **KMS** (Google Cloud or AWS), not in frontend local storage. The server signs transactions after the user authenticates; import flows are the exception where a key is supplied once to seed KMS-backed custody.
How do copy trading and signal trading differ?
**Copy trading** watches **followed Solana wallets** and mirrors their detected buys/sells into the user’s wallet per-follow rules (size, TP/SL, pause). **Signal trading** listens to **Telegram / Twitter-style** sources and trades when those channels flag tokens, with separate per-source configurati
How does the client get live balances, PnL, and notifications?**
The API exposes wallets, trades, and portfolio endpoints; **Birdeye**, **Helius**, and internal balance/price feeds supply valuations and PnL-style summaries. **Socket.IO** pushes balance, price, trade, and toast/event updates so the UI can refresh without constant polling.
