For a spot–perpetual (cash-and-carry) trade, the best FRAX route is to buy spot on Binance and short the perpetual on Binance: -0.23% gross, -0.43% net, with +0.030% a day of funding on the short leg.
Spot–spot FRAX arbitrage (buy on Binance, withdraw, deposit and sell on Gate) shows -0.03% 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 FRAX 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.
