setTokenAndPriceProvider (0x3ca82a11)

function setTokenAndPriceProvider(
    address token,
    address priceProvider,
    bool hasFunctionWithSign
) external

Sets price provider to token and its corresponding price provider.

Parameters:

Name	Type	Description
token	address	the address of token.
priceProvider	address	the address of price provider. Should implement the interface of PriceProvider.
hasFunctionWithSign	bool	true - if price provider has function with signatures.
false - if price provider does not have function with signatures.

changeActive (0x3651084e)

function changeActive(
    address priceProvider,
    address token,
    bool active
) external

Allows the moderator to change the active status of a price provider for a specific token.

Parameters:

Name	Type	Description
priceProvider	address	The address of the price provider to change the active status for.
token	address	The address of the token to change the active status for.
active	bool	The new active status to set for the price provider.

getPrice (0x41976e09)

function getPrice(
    address token
) external view returns (uint256 priceMantissa, uint8 priceDecimals)

returns tuple (priceMantissa, priceDecimals). price = priceMantissa / (10 ** priceDecimals)

Parameters:

Name	Type	Description
token	address	the address of token wich price is to return

getPriceSigned (0x52bd8224)

function getPriceSigned(
    address token,
    uint256 _priceMantissa,
    uint8 _priceDecimals,
    uint256 validTo,
    bytes memory signature
) external view returns (uint256 priceMantissa, uint8 priceDecimals)

returns the price of token multiplied by 10 ** priceDecimals given by price provider. price can be calculated as priceMantissa / (10 ** priceDecimals). i.e. price = priceMantissa / (10 ** priceDecimals).

Parameters:

Name	Type	Description
token	address	the address of token.
_priceMantissa	uint256	- the price of token (used in verifying the signature).
_priceDecimals	uint8	- the price decimals (used in verifying the signature).
validTo	uint256	- the timestamp in seconds (used in verifying the signature).
signature	bytes	- the backend signature of secp256k1. length is 65 bytes.

getEvaluation (0x81fd01ea)

function getEvaluation(
    address token,
    uint256 tokenAmount
) external view returns (uint256 evaluation)

Returns the USD evaluation of token by its tokenAmount.

Parameters:

Name	Type	Description
token	address	the address of token to evaluate.
tokenAmount	uint256	the amount of token to evaluate.

getEvaluationSigned (0xf91b9dc2)

function getEvaluationSigned(
    address token,
    uint256 tokenAmount,
    uint256 priceMantissa,
    uint8 priceDecimals,
    uint256 validTo,
    bytes memory signature
) external view returns (uint256 evaluation)

Returns the USD evaluation of token by its tokenAmount.

priceMantissa	uint256	- the price of token (used in verifying the signature).
priceDecimals	uint8	- the price decimals (used in verifying the signature).
validTo	uint256	- the timestamp in seconds (used in verifying the signature).
signature	bytes	- the backend signature of secp256k1. length is 65 bytes.
