Hi Product Hunt 👋

I'm Serhii, and I build Arbiline on my own: no team, no VC.

I traded spread and funding-rate arbitrage by hand and kept hitting the same two walls. The spread I saw was gone by the time both exchange tabs were open. And I was scared to leave positions overnight: one leg gets liquidated or ADL'd while you sleep, and you wake up unhedged.

So I built the tool I wanted:
🔍 A live scanner across 15+ exchanges and DEXes. Spreads and funding gaps are priced from order-book depth with fees on both sides, not from the last price. Public, no signup.
⚡ One click opens both legs through your own API keys. Your funds stay on your exchange accounts.
🛡️ Protection watches both legs 24/7. If one side gets closed, it closes or re-hedges the other and pings you in Telegram.
🤖 An auto-trading bot enters and exits on your targets. It runs on the server, so you can close the laptop.
🔗 DEX routes: buy a token on Solana, BSC, Base or Ethereum and short it on an exchange.
🧪 Free demo mode on every account: live prices, simulated fills, no API keys needed.

The hard part wasn't the UI. Every exchange streams order books its own way, so I ended up writing and maintaining my own exchange client in Go. And the same ticker on two exchanges isn't always the same coin: matching assets properly is what keeps you from hedging the wrong token.

An honest note: arbitrage isn't a money button. Spreads are real but short-lived, and you can lose money. Arbiline gives you speed and clean numbers, not guaranteed profit. The public table and demo mode are free, paid plans start at $20/mo.

If you trade arbitrage, tell me what's missing or what looks off. I'm here all day.
