IMultipoolManagerMethods

Functions

updatePrices

Updates price feeds for multiple tokens.

Values in each of these arrays should match with indexes (e.g. index 1 contains all data for asset 1)

function updatePrices(
    address[] calldata assetAddresses,
    FeedType[] calldata kinds,
    bytes[] calldata feedData
)
    external;

Parameters

Name	Type	Description
assetAddresses	address[]	Addresses of assets for wich to update feeds
kinds	FeedType[]	Price feed extraction strategy type
feedData	bytes[]	Data with encoded payload for price extraction

updateTargetShares

Updates target shares for multiple tokens.

Values in each of these arrays should match with indexes (e.g. index 1 contains all data for asset 1)

function updateTargetShares(
    address[] calldata assetAddresses,
    uint[] calldata targetShares
)
    external;

Parameters

Name	Type	Description
assetAddresses	address[]	Addresses of assets for wich to update target shares
targetShares	uint256[]	Share values to update to

withdrawFees

Method that allows to withdraw collected to owner fees. May be only called by owner

Sends all collected values at once

function withdrawFees(address to) external returns (uint fees);

Parameters

Name	Type	Description
to	address	Address to wich to transfer collected fees

Returns

Name	Type	Description
fees	uint256	withdrawn native token value

withdrawDeveloperFees

Method that allows to withdraw developer fees from contract

Can be invoked by anyone but is still safe as recepient is always developer address

function withdrawDeveloperFees() external returns (uint fees);

Returns

Name	Type	Description
fees	uint256	withdrawn native token value

togglePause

Method that stops or launches contract. Used in case of freezing (e.g hacks or temprorary stopping contract)

function togglePause() external;

setFeeParams

Method to change fee charging rules. All ratios are Q32 values.

Remember to always update every value as this function overrides all variables

function setFeeParams(
    uint64 newDeviationLimit,
    uint64 newHalfDeviationFee,
    uint64 newDepegBaseFee,
    uint64 newBaseFee,
    uint64 newDeveloperBaseFee,
    address newDeveloperAddress
)
    external;

Parameters

Name	Type	Description
newDeviationLimit	uint64	curve parameter that shows maximum deviation changes that may be made by callers
newHalfDeviationFee	uint64	curve parameter that is a fee ratio at the half of the curve
newDepegBaseFee	uint64	parameter that shows ratio of value taken from deviation fee as base fee
newBaseFee	uint64	parameter that shows ratio of value taken from each operation quote value
newDeveloperBaseFee	uint64	parameter that shows ratio of value that is taken from base fee share for arcanum protocol developers and maintainers
newDeveloperAddress	address	address to send arcanum protocol development and maintaince fees

setSharePriceParams

This method allows to chenge time for wich force pushed share price is valid and minimal number of unique signatures required for price force push

Called only by owner. This mechanism allow you to manage price volatility by changing valid price timeframes

function setSharePriceParams(uint128 newValidityDuration, uint newSignatureThershold) external;

Parameters

Name	Type	Description
newValidityDuration	uint128	New interval in seconds
newSignatureThershold	uint256	New number of signatures that substracted by 1 (if 0 is passed 1 signature is required)

setAuthorityRights

Method that changes permissions of accounts

Remember to always update every value as this function overrides all variables

function setAuthorityRights(
    address authority,
    bool forcePushSettlement,
    bool targetShareSettlement
)
    external;

Parameters

Name	Type	Description
authority	address	address whos permissions change
forcePushSettlement	bool	allows to sign force push data if true
targetShareSettlement	bool	allows to change target share if true
