SEI arbitrage explained
Right now Sei (SEI) trades on 10 venues we scan: 10 perpetual markets, 7 spot markets and 0 DEX pools. The lowest ask is on Variational perp at $0.068 and the highest bid on Bybit spot at $0.0681.
The widest SEI perpetual spread is between Variational and Bybit: long SEI on Variational at $0.068 and short on Bybit at $0.068 for +0.06% gross, or -0.10% 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 SEI route is to buy spot on KuCoin and short the perpetual on Bybit: -0.03% gross, -0.23% net, with +0.030% a day of funding on the short leg.
Spot–spot SEI arbitrage (buy on KuCoin, withdraw, deposit and sell on Bybit) shows +0.06% 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 SEI 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.
