Welcome to Spreadr
Spreadr is a cross-exchange spread execution engine built to capture basis and funding arbitrage opportunities. You configure a spread — a market, two venues, a target size, and a target spread — and Spreadr executes both legs for you: it watches the order books on both venues in real time, fills one leg, hedges the other within milliseconds, and repeats until your target size is filled.
It supports six venues today: Hyperliquid, Extended, Lighter, Orderly (currently via Aegis), Aster, and trade[xyz] — with many more to come. During the current rollout phase, venue access is enabled per account — if a venue isn't available on yours yet, reach out via the support channels in the app footer.
Where to start
What Spreadr is for
- Net-funding arbitrage — capture the funding-rate gap between venues on the same market. The Funding Rates tab ranks every venue pair by current opportunity, and funding accrued on your spread positions is shown live in the terminal's Positions module and the Portfolio tab.
- Basis trades — capture the price differential when the same perpetual quotes at different prices on two venues.
- Large orders — filled incrementally by continuous quoting, with each clip sized to live book depth on both legs.
What Spreadr is not
- Not a copy-trading service — every spread is configured by you.
- Not a market-making bot — Spreadr captures spread between venues, not the bid-ask within one venue.
- Not custodial — Spreadr holds per-user-encrypted trading keys that cannot withdraw funds. See Security for details.
