library of functions related to protocol fees

State Variables​

MAX_PROTOCOL_FEE​

Max protocol fee is 0.1% (1000 pips)

Increasing these values could lead to overflow in Pool.swap

uint16 public constant MAX_PROTOCOL_FEE = 1000;

FEE_0_THRESHOLD​

Thresholds used for optimized bounds checks on protocol fees

uint24 internal constant FEE_0_THRESHOLD = 1001;

FEE_1_THRESHOLD​

uint24 internal constant FEE_1_THRESHOLD = 1001 << 12;

PIPS_DENOMINATOR​

the protocol fee is represented in hundredths of a bip

uint256 internal constant PIPS_DENOMINATOR = 1_000_000;

Functions​

getZeroForOneFee​

function getZeroForOneFee(uint24 self) internal pure returns (uint16);

getOneForZeroFee​

function getOneForZeroFee(uint24 self) internal pure returns (uint16);

isValidProtocolFee​

function isValidProtocolFee(uint24 self) internal pure returns (bool valid);

calculateSwapFee​

here self is just a single direction's protocol fee, not a packed type of 2 protocol fees

function calculateSwapFee(uint16 self, uint24 lpFee) internal pure returns (uint24 swapFee);
