#### Pacifica cap

Pacifica has a maximum fee of **2.00 bps**. If your tier rate would otherwise be higher (i.e. Tier 0 at 2.50 bps), trades on Pacifica are charged at 2.00 bps instead. All other tiers are unaffected. In practice this means Tier 0 and Tier 1 users pay the same 2.00 bps rate on Pacifica.
