If tradingFeeRate is negative, it adds DIRECTION_PRECISION to the absolute fee rate. Otherwise it returns the fee rate directly.

  • Return Values:

    NameTypeDescription
    [0]uint256id The ID of ERC1155 token

decodeId​

function decodeId(uint256 id) internal pure returns (int16 tradingFeeRate)

Decode the trading fee rate from the CLB token ID of ERC1155 token type

If id is greater than or equal to DIRECTION_PRECISION, then it substracts DIRECTION_PRECISION from id and returns the negation of the substracted value. Otherwise it returns id directly.

function feeRateIndex(uint16 feeRate) internal pure returns (uint256)

tokenIds​

function tokenIds() internal pure returns (uint256[])
