The widest UNI perpetual spread is between Bybit and HTX: long UNI on Bybit at $8.18 and short on HTX at $8.20 for +0.21% gross, or +0.05% after the 0.16% two-leg fee model. No transfer is needed: both positions stay on their exchanges until the prices converge. The funding difference on this pair is +0.036% per day, which the position collects while it is open.
For a spot–perpetual (cash-and-carry) trade, the best UNI route is to buy spot on OKX and short the perpetual on HTX: +0.14% gross, -0.06% net, with +0.066% a day of funding on the short leg.
Spot–spot UNI arbitrage (buy on OKX, withdraw, deposit and sell on Gate) shows +0.09% gross right now. It only works if withdrawals on the buying exchange and deposits on the selling exchange are open, so check the D/W dots before moving coins.
Small UNI gaps usually disappear after fees, slippage and funding. Look at the Net column, the executable Depth and the spread history before trading: a gap that has been open for days is a different trade from a one-minute spike.
