Hedge every fill to the exact quantity.
GMAYFF Bot rests an order on a perp exchange and opens the matching Binance hedge when it fills. FS-Monitor shows you where funding and spreads are worth the trade.
One-time payment in crypto. No platform fees.
Example numbers. The hedge size always equals the quantity actually filled.
How a trade runs
You choose the pair and size. The bot handles the rest of the loop.
Pick a venue and a pair
Choose the primary exchange, the symbol and how much to trade.
The bot works the order
It rests a limit order on the primary venue and reprices it as the book moves.
The fill is hedged
When the order fills, the bot opens the opposite position on Binance for the exact filled base quantity.
Built to run all day
The bot is a desktop app with a compact dark interface and a live order card, so two bot windows fit side by side on a 1920 by 1080 screen.
- Exact-fill hedging. The Binance hedge uses the quantity filled on the primary exchange, not the quantity you asked for.
- Five primary venues. Kraken, AsterDEX, Hyperliquid, SoDEX and Polymarket Perps, each hedged on Binance futures.
- Cross margin on the hedge. The Binance side always runs on cross margin.
- Funding-aware guard. An auto hedge guard mode reads the monitor's funding data before it acts.
- Several instances at once. Run more than one bot, each on its own pair.
Check the spread before you size the trade
FS-Monitor puts funding rates and cross-exchange spreads into one live table, so you can see which pairs are worth opening and which to skip.
- Auto mode finds opportunities for you.
- Manual watchlists. Run a second instance with only the pairs you choose.
- Hourly and daily funding as percentages, so venues compare directly.
- Data for your bot. The monitor writes a JSON file that the bot reads.

Your payment goes straight to our wallet
No payment processor sits in the middle, so there is no platform fee and no one can hold your order. You only pay the network fee for your own transfer.
Each order gets an exact amount. Send that exact amount and the order confirms by itself.
Questions
What do I get after paying?
A download link for each app, and a signed license key that you activate for your computer, all on your order page. A license works on one computer, and you can move it to a new one by emailing support. If you gave an email, we also send the link there. Keep the order page link private.
How long does confirmation take?
It depends on the network: a few minutes for most chains, longer for Bitcoin, which waits for two confirmations. The order page updates on its own.
What if I send a different amount?
Orders match on the exact amount. If you sent a different amount, or paid after the order expired, email us your transaction hash and we will match it by hand.
What exchange permissions does the bot need?
Create API keys with trading permission only. Never enable withdrawals, and restrict the key to your IP address where the exchange allows it. The docs walk through each exchange.
Is this financial advice?
No. This is software, not advice, and trading leveraged derivatives can lose more than you deposit. Read the terms before you buy.
