Free crypto arbitrage scanner
with real net profit
Most scanners show a pretty spread %. VoltArb shows what you actually make after fees, slippage, withdrawal, and funding — across 30 CEX and DEX exchanges in real time.
- Is it free?
- Yes. The web scanner is free, no signup. Pro is optional (alerts, personal filters, unlimited tracker).
- What markets?
- Spot, perpetual futures, CEX and DEX — 30 venues. Not every token on every venue.
- Does it execute trades?
- No. You execute on the exchange. Scanner, Tracker and alerts are research tools.
- Why trust the number?
- Gross spread is walked through VWAP/slippage, fees, withdrawal/network status and funding before a net estimate is shown.
What is a crypto arbitrage scanner?
A crypto arbitrage scanner monitors the same asset on multiple exchanges and highlights price gaps (spreads). Traders buy where it is cheaper and sell where it is more expensive — or hedge with futures for delta-neutral setups.
The hard part is not finding a spread. The hard part is knowing whether the spread survives fees, thin orderbooks, closed withdrawals, and funding payments. That is what VoltArb is built for.
Why VoltArb beats “spread-only” scanners
Live orderbooks (WebSocket)
Depth from both legs — not cached snapshots that lie about fillable size.
VWAP slippage
Walk the book for $100–$5K and see the real execution price before you click.
Net profit calculator
Spread − fees − withdrawal − slippage ± funding. The only number that matters.
D/W + networks
Deposit/withdrawal status and common networks so you do not buy into a locked coin.
Funding rate arb
Ready long/short combos with net yield per day across exchanges.
Free scanner
Open in the browser. No registration. Pro adds Telegram alerts and personal filters.
How to use VoltArb in 4 steps
Open the free scanner
Go to the live table. Filter by spread, volume, exchanges, and arb type (spot-spot, spot-futures, futures-futures, DEX).
Open Tracker on a route
Check both orderbooks, VWAP slippage, D/W status, and net profit for your size.
Verify funding & history
See if funding helps or hurts, and whether the spread is growing or dying.
Trade or skip
If net profit is thin after costs — skip. Discipline beats chasing fake 8% screenshots.
VoltArb vs typical free scanners
Competitors often win SEO with “free scanner” pages. Here is the honest feature gap.
| Feature | VoltArb | Typical scanner |
|---|---|---|
| Real-time CEX + DEX | Yes (30) | Often CEX-only or delayed |
| Net profit after costs | Fees + slip + withdraw + funding | Raw spread % |
| Live orderbook depth | WebSocket both legs | Rare / snapshots |
| D/W status | In scanner + alerts | Manual check |
| Funding arb combos | Ready long/short | Raw rates table |
| Telegram Pro alerts | Filtered bot + group | Varies / paid only |
What “real-time” and net estimate mean
Methodology (updated 16 Sep 2026): “real-time” means WebSocket depth and tickers from connected venues, not a delayed screenshot. Venue coverage is the live connected set (about 30 CEX/DEX names on this page) — a venue can drop if its feed is down. Net estimate = gross spread − taker-style fees − VWAP slippage for your size − withdrawal/network cost ± funding for the hold window. It is an estimate, not a fill. Examples on this page describe product behavior; they are not live quotes.

FAQ
Is there a free crypto arbitrage scanner?
Yes. VoltArb’s web scanner is free with no registration. Pro is optional for Telegram alerts, personal filters, and unlimited tracker sessions.
Does VoltArb execute trades for me?
The Scanner, Tracker and Telegram alerts do not place trades — you decide and execute on the exchange yourself. An optional, invite-only Terminal beta exists for user-confirmed manual execution with restricted Read+Trade API keys (no withdrawals or transfers): see /legal/terminal.
Which exchanges are supported?
30 venues including Binance, Bybit, OKX, MEXC, Bitget, Gate, KuCoin, Hyperliquid, Aster, Lighter, Backpack, and more.
Why do other scanners show bigger spreads?
They often ignore slippage, fees, withdrawal status, and funding. A 5% “spread” can be a loss after real costs — VoltArb shows that before you trade.
Is funding rate arbitrage included?
Yes. VoltArb surfaces ready-to-trade long/short funding combos with net yield estimates across exchanges.
