Same asset. Two exchanges. Different rates.
Crypto perps charge a small recurring fee between longs and shorts — the funding rate. Each exchange sets its own. When they diverge, a spread opens up.
Short the expensive side. Long the cheap side.
Equal size on both. Price moves cancel out — you're delta-neutral. Funding rolls in from both legs.

Same trade shape. Different source of profit.
Same asset trading at different prices on two venues. Buy the cheap side, short the expensive side. Profit when prices converge.
