GovernorNoncesKeyedUpgradeable

Inherits: Initializable, GovernorUpgradeable, NoncesKeyedUpgradeable

An extension of {Governor} that extends existing nonce management to use {NoncesKeyed}, where the key is the low-order 192 bits of the proposalId. This is useful for voting by signature while maintaining separate sequences of nonces for each proposal. NOTE: Traditional (un-keyed) nonces are still supported and can continue to be used as if this extension was not present.

Functions

__GovernorNoncesKeyed_init

function __GovernorNoncesKeyed_init() internal onlyInitializing;

__GovernorNoncesKeyed_init_unchained

function __GovernorNoncesKeyed_init_unchained() internal onlyInitializing;

_useCheckedNonce

function _useCheckedNonce(address owner, uint256 nonce)
    internal
    virtual
    override(NoncesUpgradeable, NoncesKeyedUpgradeable);

_validateVoteSig

Check the signature against keyed nonce and falls back to the traditional nonce. NOTE: This function won't call super._validateVoteSig if the keyed nonce is valid. Side effects may be skipped depending on the linearization of the function.

function _validateVoteSig(uint256 proposalId, uint8 support, address voter, bytes memory signature)
    internal
    virtual
    override
    returns (bool);

_validateExtendedVoteSig

Check the signature against keyed nonce and falls back to the traditional nonce. NOTE: This function won't call super._validateExtendedVoteSig if the keyed nonce is valid. Side effects may be skipped depending on the linearization of the function.

function _validateExtendedVoteSig(
    uint256 proposalId,
    uint8 support,
    address voter,
    string memory reason,
    bytes memory params,
    bytes memory signature
) internal virtual override returns (bool);
