Transaction fee mining commonly referred to as โtrans-fee miningโ is the process of using transaction fees to reward the community. Unlike other exchange platforms, Biswap returns the transaction fees to the users in the form of its native token - BSW. In simple terms, when you make a swap on Biswap and pay a trading fee of 0.1%, up to 70% of the trading fee will be immediately returned to your โFee Returnโ balance in BSW tokens.
