Arbitrum One and Optimism mainnet use the SequencerChainlinkOracle family instead. Feed addresses, stale periods, direct price overrides, ownership, and ACM permissions remain per-proxy dynamic configuration.

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

This oracle fetches prices of assets from the Chainlink oracle.

Solidity API

struct TokenConfig {
  address asset;
  address feed;
  uint256 maxStalePeriod;
}

NATIVE_TOKEN_ADDR

Set this as asset address for native token on each chain. This is the underlying address for vBNB on BNB chain or an underlying asset for a native market on any chain.

address NATIVE_TOKEN_ADDR

---

prices

Manually set an override price, useful under extenuating conditions such as price feed failure

mapping(address => uint256) prices

---

tokenConfigs

Token config by assets

mapping(address => struct ChainlinkOracle.TokenConfig) tokenConfigs

---

constructor

Constructor for the implementation contract.

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

---

setDirectPrice

Manually set the price of a given asset

function setDirectPrice(address asset, uint256 price) external

Parameters

Name	Type	Description
asset	address	Asset address
price	uint256	Asset price in 18 decimals

📅 Events

• Emits PricePosted event on succesfully setup of asset price

⛔️ Access Requirements

---

setTokenConfigs

Add multiple token configs at the same time

function setTokenConfigs(struct ChainlinkOracle.TokenConfig[] tokenConfigs_) external

Parameters

Name	Type	Description
tokenConfigs_	struct ChainlinkOracle.TokenConfig[]	config array

⛔️ Access Requirements

• Only Governance

❌ Errors

• Zero length error thrown, if length of the array in parameter is 0

---

setTokenConfig

Add single token config. asset & feed cannot be null addresses and maxStalePeriod must be positive

function setTokenConfig(struct ChainlinkOracle.TokenConfig tokenConfig) public

Parameters

Name	Type	Description
tokenConfig	struct ChainlinkOracle.TokenConfig	Token config struct

📅 Events

• Emits TokenConfigAdded event on succesfully setting of the token config

⛔️ Access Requirements

• Only Governance

❌ Errors

• NotNullAddress error is thrown if asset address is null
• NotNullAddress error is thrown if token feed address is null
• Range error is thrown if maxStale period of token is not greater than zero

---

getPrice

Gets the price of a asset from the chainlink oracle

function getPrice(address asset) public view virtual returns (uint256)

Parameters

Name	Type	Description
asset	address	Address of the asset

Return Values

Name	Type	Description
[0]	uint256	Price in USD from Chainlink or a manually set price for the asset
