OraclePriceChecker

Price checker that validates swap prices using IPriceOracle implementations

This allows reusing existing oracle infrastructure (ChainlinkOracle, CurveEMAOracle, CrossAdapter, etc.)

State Variables

oracle

The price oracle to use for validation

IPriceOracle public immutable oracle;

defaultMaxDeviationBps

Maximum allowed price deviation in basis points

uint256 public immutable defaultMaxDeviationBps;

Functions

constructor

Constructor

constructor(IPriceOracle _oracle, uint256 _defaultMaxDeviationBps) payable;

Parameters

Name	Type	Description
`_oracle`	`IPriceOracle`	The IPriceOracle implementation to use
`_defaultMaxDeviationBps`	`uint256`	Maximum allowed deviation in basis points (e.g., 500 = 5%)

checkPrice

Check if a swap price meets the oracle requirements

function checkPrice(
    uint256 amountIn,
    address fromToken,
    address toToken,
    uint256 feeAmount,
    uint256 minOut,
    bytes calldata data
)
    external
    view
    override
    returns (bool);

Parameters

Name	Type	Description
`amountIn`	`uint256`	The amount of input tokens (including fee)
`fromToken`	`address`	The input token address
`toToken`	`address`	The output token address
`feeAmount`	`uint256`	The fee amount in input tokens
`minOut`	`uint256`	The minimum output amount from the solver
`data`	`bytes`	Additional data (used for max deviation bps)

Returns

Name	Type	Description
`<none>`	`bool`	True if the price is acceptable
