NoncesFacet

Diamond facet that exposes per-account nonce reads as a selectable proxy function.

Inherits Nonces for the business logic and implements IStaticFunctionSelectors for the Diamond resolver pattern. The resolver key RESOLVER_KEY_NONCES identifies this facet within the diamond proxy.

Methods

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

initializeNonces

function initializeNonces() external nonpayable

Initialises the nonces capability on the token.

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

nonces

function nonces(address _owner) external view returns (uint256)

Returns the current nonce for owner.

Parameters

Name	Type	Description
_owner	address	Address whose nonce is queried.

Returns

Name	Type	Description
_0	uint256	Current nonce value for owner.

protectedClearingCreateHoldByPartitionNonce

function protectedClearingCreateHoldByPartitionNonce(address _owner) external view returns (uint256)

Returns the current nonce for _owner used in protected clearing partition hold creations.

Incremented internally upon consumption of a valid signed protectedClearingCreateHoldByPartition operation.

Parameters

Name	Type	Description
_owner	address	Address whose clearing partition hold creation nonce is queried.

Returns

Name	Type	Description
_0	uint256	Current nonce value for _owner.

protectedClearingRedeemByPartitionNonce

function protectedClearingRedeemByPartitionNonce(address _owner) external view returns (uint256)

Returns the current nonce for _owner used in protected clearing partition redemptions.

Incremented internally upon consumption of a valid signed protectedClearingRedeemByPartition operation.

Parameters

Name	Type	Description
_owner	address	Address whose clearing partition redemption nonce is queried.

Returns

Name	Type	Description
_0	uint256	Current nonce value for _owner.

protectedClearingTransferByPartitionNonce

function protectedClearingTransferByPartitionNonce(address _owner) external view returns (uint256)

Returns the current nonce for _owner used in protected clearing partition transfers.

Incremented internally upon consumption of a valid signed protectedClearingTransferByPartition operation.

Parameters

Name	Type	Description
_owner	address	Address whose clearing partition transfer nonce is queried.

Returns

Name	Type	Description
_0	uint256	Current nonce value for _owner.

protectedCreateHoldByPartitionNonce

function protectedCreateHoldByPartitionNonce(address _owner) external view returns (uint256)

Returns the current nonce for _owner used in protected partition hold creations.

Incremented internally upon consumption of a valid signed protectedCreateHoldByPartition operation.

Parameters

Name	Type	Description
_owner	address	Address whose partition hold creation nonce is queried.

Returns

Name	Type	Description
_0	uint256	Current nonce value for _owner.

protectedRedeemFromByPartitionNonce

function protectedRedeemFromByPartitionNonce(address _owner) external view returns (uint256)

Returns the current nonce for _owner used in protected partition redemptions.

Incremented internally upon consumption of a valid signed protectedRedeemFromByPartition operation.

Parameters

Name	Type	Description
_owner	address	Address whose partition redemption nonce is queried.

Returns

Name	Type	Description
_0	uint256	Current nonce value for _owner.

protectedTransferFromByPartitionNonce

function protectedTransferFromByPartitionNonce(address _owner) external view returns (uint256)

Returns the current nonce for _owner used in protected partition transfers.

Incremented internally upon consumption of a valid signed protectedTransferFromByPartition operation.

Parameters

Name	Type	Description
_owner	address	Address whose partition transfer nonce is queried.

Returns

Name	Type	Description
_0	uint256	Current nonce value for _owner.

Events

NoncesInitialized

event NoncesInitialized()

Emitted once when the nonces capability is initialised on a token.

Fires exclusively from initializeNonces.

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.
