BoundValidator

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.

Solidity API

struct ValidateConfig {
  address asset;
  uint256 upperBoundRatio;
  uint256 lowerBoundRatio;
}

validateConfigs

validation configs by asset
