What is ARBHUB
A free public screener for funding, basis and carry opportunities across 11 exchanges. No account, no execution, no advice.
What it is
ARBHUB is a screener for cross-exchange arbitrage in crypto derivatives. It watches funding rates, prices and volumes across 11 exchanges and about 1,000 assets, normalizes them to a common scale, and ranks the widest live gaps.
Two screens do the work:
- The Matrix — every asset × every venue on one grid, sorted by the widest funding spread. See The Matrix.
- The Spread page — one pair in depth: live order books on both venues, funding schedule, fees, slippage at your size, and breakeven. See The Spread page.
Everything is public. There is no signup wall, no account, and no payment. Open the app and the full matrix is streaming.
What it is not
- It does not execute trades. ARBHUB shows market data. Orders happen on your exchange accounts, placed by you.
- It does not give signals or advice. A wide spread is a fact about the market, not a recommendation. Whether it survives fees, slippage and a funding flip is your call — the Risks section exists for exactly that.
- It does not predict. The APR column is a normalization of the current rate, not a forecast. One number, held constant for a year, produces that figure — rates do not hold constant. See APR math.
Where the numbers come from
Native exchange feeds — funding and mark prices as each venue publishes them. Quotes refresh about every 30 seconds. Venues with stale feeds are flagged rather than silently hidden, and a sanity filter removes quotes that fail cross-venue checks. Details in Data & coverage.
Who it is for
Traders who already run — or want to evaluate — delta-neutral strategies: funding-rate arbitrage between perps, cash-and-carry against spot, and basis convergence trades. If those words are new, start with Funding-rate arbitrage and the Glossary.
