BoundValidator
The BoundValidator contract is used to validate prices fetched from two different sources. Each asset has an upper and lower bound ratio set in the config. In order for a price to be valid it must fall within this range of the validator price.
struct ValidateConfig {
address asset;
uint256 upperBoundRatio;
uint256 lowerBoundRatio;
}
