IFtsoManager#

event AccruingUnearnedRewardsFailed(
    uint256 epochId
)

Unexpected failure while accruing unearned rewards. This should be a rare occurrence.

event DistributingRewardsFailed(
    address ftso,
    uint256 epochId
)

Unexpected failure while distributing rewards. This should be a rare occurrence.

event FallbackMode(
    bool fallbackMode
)

Emitted when the fallback mode of the FTSO manager changes its state. Fallback mode is a recovery mode, where only data from a trusted subset of FTSO data providers is used to calculate the final price.

The FTSO Manager enters the fallback mode when ALL FTSOs are in fallback mode.

event FinalizingPriceEpochFailed(
    contract IIFtso ftso,
    uint256 epochId,
    enum IFtso.PriceFinalizationType failingType
)

Unexpected failure while finalizing a price epoch. This should be a rare occurrence.

event FtsoAdded(
    contract IIFtso ftso,
    bool add
)

Emitted when a new FTSO has been added or an existing one has been removed.

event FtsoFallbackMode(
    contract IIFtso ftso,
    bool fallbackMode
)

Emitted when the fallback mode of an FTSO changes its state.

event InitializingCurrentEpochStateForRevealFailed(
    contract IIFtso ftso,
    uint256 epochId
)

Unexpected failure while initializing a price epoch. This should be a rare occurrence.

event PriceEpochFinalized(
    address chosenFtso,
    uint256 rewardEpochId
)

Emitted when a price epoch ends, this is, after the reveal phase, when final prices are calculated.

event RewardEpochFinalized(
    uint256 votepowerBlock,
    uint256 startBlock
)

Emitted when a reward epoch ends and rewards are available.

event UseGoodRandomSet(
    bool useGoodRandom,
    uint256 maxWaitForGoodRandomSeconds
)

Emitted when the requirement to provide good random numbers has changed.

As part of the FTSO protocol, data providers must submit a random number along with their price reveals. When good random numbers are enforced, all providers that submit a hash must then submit a reveal with a random number or they will be punished. This is a measure against random number manipulation.

function active(
) external view returns (
    bool);

Returns whether the FTSO Manager is active or not.

function getCurrentPriceEpochData(
) external view returns (
    uint256 _priceEpochId,
    uint256 _priceEpochStartTimestamp,
    uint256 _priceEpochEndTimestamp,
    uint256 _priceEpochRevealEndTimestamp,
    uint256 _currentTimestamp);

Returns timing information for the current price epoch. All intervals are half-closed: end time is not included. All timestamps are in seconds since UNIX epoch.

See the FTSO page for information about the different submission phases.

function getCurrentPriceEpochId(
) external view returns (
    uint256 _priceEpochId);

Returns current price epoch ID.

function getCurrentRewardEpoch(
) external view returns (
    uint256);

Returns current reward epoch ID (the one currently running).

function getFallbackMode(
) external view returns (
    bool _fallbackMode,
    contract IIFtso[] _ftsos,
    bool[] _ftsoInFallbackMode);

Returns whether the FTSO Manager is currently in fallback mode.

In this mode only submissions from trusted providers are used.

function getFtsos(
) external view returns (
    contract IIFtso[] _ftsos);

Returns the list of currently active FTSOs.

function getPriceEpochConfiguration(
) external view returns (
    uint256 _firstPriceEpochStartTs,
    uint256 _priceEpochDurationSeconds,
    uint256 _revealEpochDurationSeconds);

Returns the current values for price epoch timing configuration.

See the FTSO page for information about the different submission phases.

function getRewardEpochConfiguration(
) external view returns (
    uint256 _firstRewardEpochStartTs,
    uint256 _rewardEpochDurationSeconds);

Returns the current values for reward epoch timing configuration.

See the Reward epochs box.

function getRewardEpochToExpireNext(
) external view returns (
    uint256);

Return reward epoch that will expire next, when a new reward epoch is initialized.

Reward epochs older than 90 days expire, and any unclaimed rewards in them become inaccessible.

function getRewardEpochVotePowerBlock(
    uint256 _rewardEpoch
) external view returns (
    uint256);

Returns the vote power block that was used for a past reward epoch.
