Every transaction on BNB Chain pays a small network fee (gas) in BNB. That includes buying, selling, approving, staking and claiming. Keep a little BNB in your wallet even if you only hold $FLAZE. On FlazeSwap the 0.05% protocol fee is also paid in BNB. A Vault emergency exit costs about 0.01 BNB too.
Check it yourself: The FlazeRouter's feeBps() reads 5 (0.05%) and MAX_FEE_BPS() reads 100 (1%). View on BscScan
