The widest COTI perpetual spread is between Binance and KuCoin: long COTI on Binance at $0.0131 and short on KuCoin at $0.0131 for +0.08% gross, or -0.08% 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 0.000% per day, which the position collects while it is open.
For a spot–perpetual (cash-and-carry) trade, the best COTI route is to buy spot on Binance and short the perpetual on KuCoin: 0.00% gross, -0.20% net, with +0.030% a day of funding on the short leg.
Spot–spot COTI arbitrage (buy on Binance, withdraw, deposit and sell on KuCoin) shows 0.00% 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 COTI 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.
