B arbitrage explained

Right now BUILDon (B) trades on 7 venues we scan: 7 perpetual markets, 3 spot markets and 0 DEX pools. The lowest ask is on Gate spot at $0.1624 and the highest bid on MEXC perp at $0.1629.

The widest B perpetual spread is between Bybit and MEXC: long B on Bybit at $0.1625 and short on MEXC at $0.1629 for +0.26% 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 B route is to buy spot on Gate and short the perpetual on MEXC: +0.30% gross, +0.10% net, with +0.030% a day of funding on the short leg.

Spot–spot B arbitrage (buy on Gate, withdraw, deposit and sell on Bitget) 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 B 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.
