Spot-Perp Funding Arbitrage — cash-and-carry scanner across 8 spot venues and every perpetual exchange Perpia tracks

Cash-and-carry is the spot-perp form of a funding trade: buy the asset on a spot exchange and short the same size of its perpetual on a venue paying positive funding. The two positions cancel most of the price exposure, and the short perp collects funding from longs each interval. Unlike a perp-perp spread it needs no second perpetual venue and has no borrow leg, but it does tie up full spot collateral, and the return is only the perp's funding minus fees on both sides — not a spread between two venues. Net APR below subtracts entry and exit fees, both legs' bid/ask spread and estimated slippage. Rows the scanner flagged as low-liquidity are excluded.
