Title: OracleWithValidationFactory

CREATE2 factory deploying OracleWithValidation instances.

The factory rejects zero addresses, identical oracles, and maxOracleDeviation >= 1e18.

The overpricing maxOracleDeviation permits must stay within the buffer the market allows, which is (1 - LLTV * maxLif), where maxLif is the max Morpho liquidation incentive factor of any market consuming the oracle. A liquidation seizes collateral worth repaidDebt * maxLif, so once overpricing exceeds this buffer a liquidation no longer covers the debt and bad debt accrues. The deviation is scaled by the primary price, so a threshold d allows up to d / (1 - d) effective overpricing (e.g. 5% allows ~5.26%); leave headroom below the buffer for both this and natural oracle drift. Setting the threshold too tight can also reject valid prices during routine drift, blocking price() and halting liquidations, which can let bad debt accumulate.

Functions

createOracleWithValidation

Deploys a new OracleWithValidation via CREATE2.

Reverts if an oracle address is zero, the two oracles are identical, or maxOracleDeviation >= 1e18.

function createOracleWithValidation(
    IOracle primaryOracle,
    IOracle validationOracle,
    uint256 maxOracleDeviation,
    bool revertOnValidationOracleFailure,
    address owner,
    bytes32 salt
) external returns (address oracle);

Parameters

Name	Type	Description
primaryOracle	IOracle	The primary oracle, always used for the price.
validationOracle	IOracle	The validation oracle used to bound-check the primary's price.
maxOracleDeviation	uint256	The maximum allowed deviation, in WAD.
revertOnValidationOracleFailure	bool	Whether price() reverts when the validation oracle call reverts.
owner	address	The initial owner of the deployed oracle.
salt	bytes32	The CREATE2 salt.

Returns

Name	Type	Description
oracle	address	The address of the deployed oracle.
