Bounds are per-asset mutable configuration. This version map does not certify any current upper/lower ratio.

The proxy API inherits owner, pendingOwner, transferOwnership, acceptOwnership, renounceOwnership, accessControlManager, and owner-only setAccessControlManager.

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

mapping(address => struct BoundValidator.ValidateConfig) validateConfigs

---

constructor

Constructor for the implementation contract. Sets immutable variables.

constructor() public

---

initialize

Initializes the owner of the contract

function initialize(address accessControlManager_) external

Parameters

Name	Type	Description
accessControlManager_	address	Address of the access control manager contract

---

setValidateConfigs

Add multiple validation configs at the same time

function setValidateConfigs(struct BoundValidator.ValidateConfig[] configs) external

Parameters

Name	Type	Description
configs	struct BoundValidator.ValidateConfig[]	Array of validation configs

📅 Events

• Emits ValidateConfigAdded for each validation config that is successfully set

⛔️ Access Requirements

• Only Governance

❌ Errors

• Zero length error is thrown if length of the config array is 0

---

setValidateConfig

Add a single validation config

function setValidateConfig(struct BoundValidator.ValidateConfig config) public

Parameters

Name	Type	Description
config	struct BoundValidator.ValidateConfig	Validation config struct

📅 Events

• Emits ValidateConfigAdded when a validation config is successfully set

⛔️ Access Requirements

• Only Governance

❌ Errors

• Null address error is thrown if asset address is null
• Range error thrown if bound ratio is not positive
• Range error thrown if lower bound is greater than or equal to upper bound

---

validatePriceWithAnchorPrice

Test reported asset price against anchor price

function validatePriceWithAnchorPrice(address asset, uint256 reportedPrice, uint256 anchorPrice) public view virtual returns (bool)

Parameters

Name	Type	Description
asset	address	asset address
reportedPrice	uint256	The price to be tested
anchorPrice	uint256

❌ Errors

• Missing error thrown if asset config is not set
• Price error thrown if anchor price is not valid
