BalanceTrackerAdjustedFacet

Diamond facet that exposes historical, timestamp-parameterised balance queries through the IBalanceTrackerAdjusted interface, registered under RESOLVER_KEY_BALANCE_TRACKER_ADJUSTED.

Inherits balance logic from BalanceTrackerAdjusted and satisfies IStaticFunctionSelectors for Diamond proxy selector registration. Exposes one selector: balanceOfAt.

Methods

balanceOfAt

function balanceOfAt(address _tokenHolder, uint256 _timestamp) external view returns (uint256)

Returns the total token balance of a token holder at a given timestamp, simulating non-triggered balance adjustments up to that point in time.

Parameters

Name	Type	Description
_tokenHolder	address	The address of the token holder.
_timestamp	uint256	The Unix timestamp at which the balance is evaluated.

Returns

Name	Type	Description
_0	uint256	The adjusted total balance of the token holder at _timestamp.

getStaticFunctionSelectors

function getStaticFunctionSelectors() external pure returns (bytes4[])

Gets all function selectors of a facet

Returns

Name	Type	Description
_0	bytes4[]	Face functions selectors

getStaticInterfaceIds

function getStaticInterfaceIds() external pure returns (bytes4[])

Gets all interfaces ids of a facet.

Returns

Name	Type	Description
_0	bytes4[]	Face interface ids

getStaticResolverKey

function getStaticResolverKey() external pure returns (bytes32 staticResolverKey_)

Gets the static resolver key

Returns

Name	Type	Description
staticResolverKey_	bytes32	Static resolver key

initializeBalanceTrackerAdjusted

function initializeBalanceTrackerAdjusted() external nonpayable

Initialises the adjusted balance tracker capability on the token.

Callable once; subsequent calls revert with FacetAlreadyRegistered. Requires DEFAULT_ADMIN_ROLE. Called by the factory during deployment.

Events

BalanceTrackerAdjustedInitialized

event BalanceTrackerAdjustedInitialized()

Emitted once when the adjusted balance tracker capability is initialised on a token.

Fires exclusively from initializeBalanceTrackerAdjusted after the storage write succeeds.

Errors

AccountHasNoRole

error AccountHasNoRole(address account, bytes32 role)

Thrown when an account does not hold a required role.

Parameters

Name	Type	Description
account	address	The account that lacks the role.
role	bytes32	The role that is not held.

FacetAlreadyRegistered

error FacetAlreadyRegistered(bytes32 facetId, uint256 lastVersion)

Raised when an initialiser tries to register a facet that already has a non-zero last registered version (i.e. the facet is being re-initialised on a fresh install).

Parameters

Name	Type	Description
facetId	bytes32	Identifier of the offending facet.
lastVersion	uint256	Last version recorded for that facet at the time of the check.

UnrecognizedResolverProxyVersion

error UnrecognizedResolverProxyVersion(bytes8 _resolverProxyVersion)

Thrown when the provided proxy version does not match any BLR compatible standard.

Parameters

Name	Type	Description
_resolverProxyVersion	bytes8	proxy version that is not compatible with the BLR.

WalletRecovered

error WalletRecovered()

Thrown when attempting to recover a wallet that has already been recovered.
