PriceAdapterRegistry

Price Adapter Registry using UUPS upgradeable pattern

This contract allows the configuration of price adapters for various assets in the investment universe.

configAddress

address configAddress

Orion Config contract address

underlyingAsset

address underlyingAsset

Underlying asset address

priceAdapterDecimals

uint8 priceAdapterDecimals

Price Adapter Precision

adapterOf

mapping(address => contract IPriceAdapter) adapterOf

Mapping of asset addresses to their corresponding price adapters

upgradeTimelock

address upgradeTimelock

Address of the upgrade timelock that must authorise all implementation upgrades

onlyConfig

modifier onlyConfig()

constructor

constructor() public

Constructor that disables initializers for the implementation contract

initialize

function initialize(address configAddress_) public

Initializer function (replaces constructor)

Parameters

Name	Type	Description
configAddress_	address	The address of the OrionConfig contract

setPriceAdapter

function setPriceAdapter(address asset, contract IPriceAdapter adapter) external

Parameters

Name	Type	Description
asset	address	The address of the asset.
adapter	contract IPriceAdapter	The price adapter for the asset.

getPrice

function getPrice(address asset) external view returns (uint256)

Returns the price of the given asset via its assigned price adapter.

The asset shall be whitelisted in the OrionConfig contract, therefore assigned an adapter in adapterOf. Returned value is always expected to have priceAdapterDecimals decimals.

Parameters

Name	Type	Description
asset	address	The address of the asset.

Return Values

Name	Type	Description
[0]	uint256	The price of the asset, normalized to priceAdapterDecimals decimals.

setUpgradeTimelock

function setUpgradeTimelock(address newTimelock) external

Sets the upgrade timelock address.

If no timelock is set yet, only the protocol admin may call this. Once a timelock is active, only the timelock itself may replace it, preventing the admin from bypassing the delay.

Parameters

Name	Type	Description
newTimelock	address	The new timelock address (e.g. OpenZeppelin TimelockController); address(0) not permitted

_authorizeUpgrade

function _authorizeUpgrade(address) internal view

Authorizes an upgrade to a new implementation

Requires the caller to be the upgrade timelock (if set) or the protocol admin (during initial bootstrapping before a timelock has been configured).
