Git Source

Inherits: BaseOracleFactory

Title: ChainlinkOracleFactory

Author: OlympusDAO

Factory contract for deploying ChainlinkOracle clones for base/quote token pairs

Uses ClonesWithImmutableArgs for gas-efficient oracle deployment

Constants

ORACLE_IMPLEMENTATION

Reference implementation for cloning

ChainlinkOracleCloneable public immutable ORACLE_IMPLEMENTATION;

Functions

constructor

Constructs a new ChainlinkOracleFactory

Reverts if priceCache_ is not a valid IPriceCache policy for this Kernel.

constructor(Kernel kernel_, address priceCache_) BaseOracleFactory(kernel_, priceCache_);

Parameters

Name	Type	Description
kernel_	Kernel	The Kernel address
priceCache_	address	The price cache policy address

_getOracleImplementation

Returns the Chainlink oracle implementation address for cloning

function _getOracleImplementation() internal view override returns (address);

Returns

Name	Type	Description
<none>	address	The address of the ChainlinkOracleCloneable implementation

_encodeOracleData

Encodes oracle-specific data for cloning

Generates oracle name and encodes immutable args.

function _encodeOracleData(
        address baseToken_,
        address quoteToken_,
        uint48 maxAge_,
        bytes calldata
    ) internal view override returns (bytes memory);

Parameters

Name	Type	Description
baseToken_	address	The base token address
quoteToken_	address	The quote token address
maxAge_	uint48	The maximum age (in seconds) of cached prices used by the oracle
_	bytes	Service-specific custom parameters (can be empty)

Returns

Name	Type	Description
<none>	bytes	bytes The encoded bytes for cloning
