B3 arbitrage explained

Right now B3 (Base) (B3) trades on 6 venues we scan: 4 perpetual markets, 4 spot markets and 0 DEX pools. The lowest ask is on Bybit perp at $0.000738 and the highest bid on Bybit spot at $0.000739.

The widest B3 perpetual spread is between MEXC and Bybit: long B3 on MEXC at $0.000738 and short on Bybit at $0.000738 for -0.07% gross, or -0.23% 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 +0.001% per day, which the position collects while it is open.

For a spot–perpetual (cash-and-carry) trade, the best B3 route is to buy spot on MEXC and short the perpetual on Bybit: -0.15% gross, -0.35% net, with -0.219% a day of funding on the short leg.

Spot–spot B3 arbitrage (buy on MEXC, withdraw, deposit and sell on Bybit) shows -0.04% 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 B3 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.
