Inherits: IMorphoChainlinkOracleV2Factory

This contract allows to create MorphoChainlinkOracleV2 oracles, and to index them easily.

State Variables

mapping(address => bool) public isMorphoChainlinkOracleV2

Functions

createMorphoChainlinkOracleV2

Here is the list of assumptions that guarantees the oracle behaves as expected:

• The vaults, if set, are ERC4626-compliant.
• The feeds, if set, are Chainlink-interface-compliant.
• Decimals passed as argument are correct.
• The base vaults's sample shares quoted as assets and the base feed prices don't overflow when multiplied.
• The quote vault's sample shares quoted as assets and the quote feed prices don't overflow when multiplied.

function createMorphoChainlinkOracleV2(
    IERC4626 baseVault,
    uint256 baseVaultConversionSample,
    AggregatorV3Interface baseFeed1,
    AggregatorV3Interface baseFeed2,
    uint256 baseTokenDecimals,
    IERC4626 quoteVault,
    uint256 quoteVaultConversionSample,
    AggregatorV3Interface quoteFeed1,
    AggregatorV3Interface quoteFeed2,
    uint256 quoteTokenDecimals,
    bytes32 salt
) external returns (IMorphoChainlinkOracleV2 oracle);

Parameters

Name	Type	Description
baseVault	IERC4626	Base vault. Pass address zero to omit this parameter.
baseVaultConversionSample	uint256	The sample amount of base vault shares used to convert to underlying. Pass 1 if the base asset is not a vault. Should be chosen such that converting baseVaultConversionSample to assets has enough precision.
baseFeed1	AggregatorV3Interface	First base feed. Pass address zero if the price = 1.
baseFeed2	AggregatorV3Interface	Second base feed. Pass address zero if the price = 1.
baseTokenDecimals	uint256	Base token decimals.
quoteVault	IERC4626	Quote vault. Pass address zero to omit this parameter.
quoteVaultConversionSample	uint256	The sample amount of quote vault shares used to convert to underlying. Pass 1 if the quote asset is not a vault. Should be chosen such that converting quoteVaultConversionSample to assets has enough precision.
quoteFeed1	AggregatorV3Interface	First quote feed. Pass address zero if the price = 1.
quoteFeed2	AggregatorV3Interface	Second quote feed. Pass address zero if the price = 1.
quoteTokenDecimals	uint256	Quote token decimals.
salt	bytes32	The salt to use for the CREATE2.
