We are launching on both Eth and MATIC/Polygon with the hope that EIP1559 will assist with ETH fees. Honestly ETH fees have been the lowest they've been in a long time... have you made an eth transaction lately? GWEI is extremely low. We support bnb but its not for us, we discussed it, but ultimately ETH/MATIC/Polygon was our selection, staying in the eth realm. Thank you for the question.
Alright, the gas is low, at least not reach 100 gwei for a transaction.
