I built an open-source crypto trading bot that runs 4 exchanges from one server

GainAlgo is an MIT-licensed crypto trading bot I've been building. The latest update lets it manage four exchanges from a single server and one dashboard:

Exchange	Futures (USDT-M)	Spot
Binance	✅	✅
Bybit	✅	✅
Upbit	—	✅
Bithumb	—	✅

That's 2 futures + 4 spot markets, all in one process.

Honesty first: it's not a money machine

On its own, the bot is roughly break-even. I think of it as tilling the field and standing guard 24/7 — the human still does the final harvest. Defaults are deliberately safe: every engine off, paper mode, single server. Live trading is an explicit, per-exchange opt-in.

If you came for "wake up to money piling up," this isn't that. It's a framework you tune — together.

Why one server?

Running a separate bot per exchange means juggling windows and duplicated infra. GainAlgo keeps them in one place but fully isolated:

Capital — one exchange's balance/positions never leak into another's sizing.
Records — trade journals, daily P&L, and gate stats are kept per-exchange.
Settings — entry/exit configs are tuned independently per exchange.

One screen, zero cross-contamination.

What shipping multi-exchange taught me

Before open-sourcing the latest work, I ran a multi-agent adversarial audit over the code and fixed what it surfaced:

a paper-mode path that still queried the live account,
missing order idempotency (a retry could double-fill),
per-exchange record files that could overwrite each other.

Small bot, but I'd rather knock on the bridge before crossing it.

Try it

git clone https://github.com/gainalgo/nunnaya

Copy .env.example → .env, fill only the exchange keys you use (withdrawal permission off), and run. It boots in paper mode by default — observe first.
