function addFtso(
    uint256 _ftsoIndex
) external;

Create an empty whitelist with default size for a new FTSO.

Only ftsoManager can call this method.

function cancelGovernanceCall(
    bytes4 _selector
) external;

Cancel a timelocked governance call before it has been executed.

Only governance can call this method.

function chillVoter(
    address _voter,
    uint256 _noOfRewardEpochs,
    uint256[] _ftsoIndices
) external returns (
    bool[] _removed,
    uint256 _untilRewardEpoch);

Used to chill a data provider, this is, remove it from the whitelist for a specified number of reward epochs.

Only governance can call this method.

function chilledUntilRewardEpoch(
    address _voter
) external view returns (
    uint256);

In case of providing bad prices (e.g. collusion), the voter can be chilled for a few reward epochs. A voter can whitelist again from a returned reward epoch onwards.

function copyWhitelist(
    uint256 _ftsoIndex

function executeGovernanceCall(
    bytes4 _selector
) external;

Execute the timelocked governance calls once the timelock period expires.

Only executor can call this method.

function getAddressUpdater(
) public view returns (
    address _addressUpdater);

Returns the configured address updater.

function getFtsoWhitelistedPriceProviders(
    uint256 _ftsoIndex
) public view returns (

Gets whitelisted price providers for the FTSO at a given index.

function getFtsoWhitelistedPriceProvidersBySymbol(
    string _symbol
) external view returns (
    address[]);

Gets whitelisted price providers for the FTSO with a specified symbol.

function governance(
) public view returns (
    address);

Returns the current effective governance address.

function maxVotersForFtso(
    uint256 _ftsoIndex
) external view returns (
    uint256);

function removeFtso(
    uint256 _ftsoIndex
) external;

Clear whitelist for a removed FTSO.

function removeTrustedAddressFromWhitelist(
    address _trustedAddress,
    uint256 _ftsoIndex
) external;

function requestFullVoterWhitelisting(
    address _voter
) external returns (
    uint256[] _supportedIndices,
    bool[] _success);

Requests whitelisting an account to act as a data provider for all active FTSOs. May be called by any address, including the voter itself.

function requestWhitelistingVoter(
    address _voter,
    uint256 _ftsoIndex
) external;

Requests whitelisting an account to act as a data provider for a specific FTSO. Reverts if the vote power of the account is too low. May be called by any address, including the voter itself.

function setDefaultMaxVotersForFtso(
    uint256 _defaultMaxVotersForFtso
) external;

Set the maximum number of voters in the whitelist for a new FTSOs.

Only governance can call this method.

function switchToProductionMode(
) external;

    address[] _contractAddresses
) external;

External method called from AddressUpdater only.

modifier onlyFtsoManager()

Only the ftsoManager can call this method.

modifier voterNotChilled(    address _voter)

Only data providers that have not been chilled can perform this action.
