Inherits: JBChainlinkV3PriceFeed

An IJBPriceFeed implementation that reports prices from a Chainlink AggregatorV3Interface from optimistic sequencers.

State Variables

GRACE_PERIOD_TIME

How long the sequencer must be re-active in order to return a price.

uint256 public immutable GRACE_PERIOD_TIME;

SEQUENCER_FEED

The Chainlink sequencer feed that prices are reported from.

AggregatorV2V3Interface public immutable SEQUENCER_FEED;

Functions

constructor

constructor(
    AggregatorV3Interface feed,
    uint256 gracePeriod,
    AggregatorV2V3Interface sequencerFeed,
    uint256 threshold
)
    JBChainlinkV3PriceFeed(feed, threshold);

Parameters

Name	Type	Description
feed	AggregatorV3Interface	The Chainlink feed to report prices from.
gracePeriod	uint256	How long the sequencer should have been re-active before returning prices.
sequencerFeed	AggregatorV2V3Interface	The Chainlink feed to report sequencer status.
threshold	uint256	How many blocks old a price update may be.

currentUnitPrice

Gets the current price (per 1 unit) from the feed.

function currentUnitPrice(uint256 decimals) public view override returns (uint256);

Parameters

Name	Type	Description
decimals	uint256	The number of decimals the return value should use.

Returns

Name	Type	Description
<none>	uint256	The current unit price from the feed, as a fixed point number with the specified number of decimals.
