For traders, the fee is always taken on the amount paid. The Protocol and Referral fees translate into LP tokens.

For regular pools (Swap function), if there is no account to receive the Referral Fee, it goes to all LPs of that pool as a form of increased LP tokens.x3

For stablecoin pools (StableSwap function), if there is no account to receive the Referral Fee, it goes to the Protocol Fee as a form of increased LP tokens.
