SUN arbitrage explained
Right now Sun Token (SUN) trades on 8 venues we scan: 8 perpetual markets, 6 spot markets and 0 DEX pools. The lowest ask is on Bybit perp at $0.0168 and the highest bid on MEXC spot at $0.0168.
The widest SUN perpetual spread is between Bybit and HTX: long SUN on Bybit at $0.0168 and short on HTX at $0.0168 for +0.05% gross, or -0.11% 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 +0.636% per day, which the position collects while it is open.
For a spot–perpetual (cash-and-carry) trade, the best SUN route is to buy spot on KuCoin and short the perpetual on HTX: -0.12% gross, -0.32% net, with +0.015% a day of funding on the short leg.
Spot–spot SUN arbitrage (buy on KuCoin, withdraw, deposit and sell on MEXC) shows +0.05% 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 SUN 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.
