Crypto markets are fragmented by design. The same asset can print different prices on Binance, OKX, Bybit, or a smaller venue — and perpetual funding can pull those prices apart again every few hours. An arbitrage scanner crypto stack exists to turn that fragmentation into a watchlist of executable gaps, not a spreadsheet of theoretical spreads.
This guide explains how modern scanners detect cross-exchange price and funding-rate discrepancies in real time, walks through the setups traders actually run (spot-spot, funding-rate, triangular), and outlines the risk controls and execution steps you need before small inefficiencies become real PnL. Along the way we use MoziAI Arbitrage Radar, Smart Alerts, and AI Trade Radar as concrete examples of how live feeds, alert routing, and AI context shorten time-to-opportunity — without custody and without auto-trading your account.
What an arbitrage scanner actually watches
A serious scanner is more than a mid-price comparison. Mid prices look pretty; fills happen on the bid and ask. Good tooling typically:
Ingests multi-exchange WebSocket quotes and normalizes symbols (BTCUSDT vs BTC-USDT vs XBTUSD).
Builds spreads from executable sides — buy the ask on venue A, sell the bid on venue B — then subtracts fees and estimated slippage.
Tracks perpetual funding rates and projected funding payments over the next settlement windows.
Applies thresholds so you only see opportunities that clear your minimum net edge after costs.
Ages signals quickly: a 12 bps gap that existed 40 seconds ago may already be gone.
MoziAI’s Arbitrage Radar is built around that loop — continuous cross-venue and funding scans with readiness-style signals you can inspect before you act. Pair it with Auto Arbitrage when you want a more structured view of monitored opportunities, still with you in control of exchange accounts.
Strategy 1: Spot–spot (cross-exchange) arbitrage
Classic crypto arbitrage: buy where the coin is cheaper, sell where it is richer, flatten inventory or transfer when the gap pays for transfer time and fees.
What the scanner flags
Relative mispricings on the same spot pair across venues, after fee tiers and typical book depth. Scanners help most when you cannot stare at twenty order books.
Execution sketch
Confirm both legs are liquid enough for your size.
2. Open the cheap leg and the rich leg as close to simultaneously as your stack allows (API preferred).
3. Account for deposit/withdrawal delays if you flatten by transfer instead of hedging on derivatives.
4. Re-check the spread after fees — many “obvious” gaps die once maker/taker and slippage are honest.
Risk controls
Withdrawal queues, KYC freezes, and chain congestion can strand inventory.
One-sided fills leave directional exposure; treat residual risk like a trade, not “free money.”
Prefer venues you already trust with hot-wallet limits and API withdraw locks.
Strategy 2: Funding-rate arbitrage
Perpetual futures use funding to tether contract price to spot. When funding is strongly positive, longs pay shorts (and vice versa). Traders look for funding that, net of basis and fees, compensates for holding a hedged book.
What the scanner flags
Cross-exchange or spot-vs-perp combinations where projected funding, basis, and carry look attractive after costs. A dedicated funding view beats manually refreshing exchange stats pages.
Execution sketch
Define the hedge: often long spot / short perp, or the reverse, sized so delta is near flat.
Model the next N funding intervals, not only the current printed rate.
Include funding caps, exchange-specific formulas, and the cost to roll or close.
Set exit rules when funding normalizes or basis blows out against you.
Risk controls
Funding can flip; basis can move faster than funding accrues.
Liquidation risk on the derivative leg if volatility spikes and margin is thin.
Use alerts for funding extremes and basis breaks so you are not glued to the screen — MoziAI Smart Alerts are built for threshold-style notification workflows.
Strategy 3: Triangular (and multi-leg) arbitrage
Triangular arb looks for inconsistent cross rates inside one venue or across a small set of pairs (for example BTC/USDT, ETH/USDT, ETH/BTC). Margins are often tiny; speed and fee tier matter more than narrative.
What the scanner flags
Closed loops whose product of rates diverges from 1.0 by more than your cost buffer. Many retail traders overestimate how often these survive latency.
Execution sketch
Pre-compute fee-inclusive edge; ignore loops that only work on mid prices.
Execute legs with the lowest latency path you have; partial fills destroy the math.
Keep notional small until you measure real fill quality on that venue.
Risk controls
Latency and queue position dominate; if you are last in line, you are exit liquidity for someone faster.
API rate limits and order throttles can strand a partial basket.
How MoziAI shortens time-to-opportunity
Scanners surface candidates; traders still need context and a wake-up path.
Arbitrage Radar — live structural opportunities across spreads and funding so you are not building the entire watchlist by hand. Start at moziai.xyz/arbitrage.
Smart Alerts — route price, move, or market-condition pings to channels you already use, so monitoring does not require an always-on chart tab. Configure at Price Alerts.
AI Trade Radar — when you need a near-term read beyond the spread itself (news, open interest, long/short structure, AI win-rate style context), open AI Trade Radar. Use it as decision support, not autopilot.
Important: MoziAI does not place trades, does not custody user funds, and does not promise profits. You keep exchange accounts, keys, and risk limits under your control.
Practical setup tips before you chase the next gap
Write your cost model once — fee tiers, expected slippage by size, transfer time, and minimum net bps.
Cap inventory per venue — assume a venue can pause withdrawals on the worst day of the month.
Alert on thresholds, not every tick — noisy alerts train you to ignore the scanner.
Paper the workflow — time how long detection → decision → dual-leg fill actually takes on your stack.
Separate research from execution — use Radar/Alerts to notice; use your own exchange APIs or UI to act.
Brief “flagged opportunity” patterns (illustrative)
These are pattern sketches, not live trades or performance claims:
Spot–spot: Scanner shows Asset X bid on Venue B still above Venue A ask after fees for your size → you verify depth, then hedge or transfer per your playbook.
Funding: Funding on Venue C prints elevated while basis remains stable enough for a hedged carry → you size to margin rules and set an alert if funding mean-reverts.
Triangular: Loop edge appears inside one liquid venue for a few hundred milliseconds → only relevant if your latency and fees clear the bar; otherwise skip.
FAQ: arbitrage scanner crypto
Is crypto arbitrage risk-free?
No. Execution risk, transfer risk, liquidation risk, and fee drag are real. Scanners reduce search cost; they do not delete market risk.
Do I need a bot on day one?
Not necessarily. Many traders start with a scanner + alerts + manual dual-leg execution on small size, then automate only what they have measured.
Where should I start on MoziAI?
Open Arbitrage Radar for opportunity monitoring, add Smart Alerts for wake-ups, and use AI Trade Radar when you want broader market context. Official site: moziai.xyz.
