GovernorSettingsUpgradeable

Extension of {Governor} for settings updatable through governance. Available since v4.4.

Methods

BALLOT_TYPEHASH

function BALLOT_TYPEHASH() external view returns (bytes32)

Returns

NameTypeDescription
_0bytes32undefined

COUNTING_MODE

function COUNTING_MODE() external pure returns (string)

module:voting

A description of the possible support values for {castVote} and the way these votes are counted, meant to be consumed by UIs to show correct vote options and interpret the results. The string is a URL-encoded sequence of key-value pairs that each describe one aspect, for example support=bravo&quorum=for,abstain. There are 2 standard keys: support and quorum. - support=bravo refers to the vote options 0 = Against, 1 = For, 2 = Abstain, as in GovernorBravo. - quorum=bravo means that only For votes are counted towards quorum. - quorum=for,abstain means that both For and Abstain votes are counted towards quorum. If a counting module makes use of encoded params, it should include this under a params key with a unique name that describes the behavior. For example: - params=fractional might refer to a scheme where votes are divided fractionally between for/against/abstain. - params=erc721 might refer to a scheme where specific NFTs are delegated to vote. NOTE: The string can be decoded by the standard https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams JavaScript class.

accountaddressundefined

Returns

NameTypeDescription
_0boolundefined

hashProposal

function hashProposal(address[] targets, uint256[] values, bytes[] calldatas, bytes32 descriptionHash) external pure returns (uint256)

See {IGovernor-hashProposal}. The proposal id is produced by hashing the ABI encoded targets array, the values array, the calldatas array and the descriptionHash (bytes32 which itself is the keccak256 hash of the description string). This proposal id can be produced from the proposal data which is part of the {ProposalCreated} event. It can even be computed in advance, before the proposal is submitted. Note that the chainId and the governor address are not part of the proposal id computation. Consequently, the same proposal (with same operation and same description) will have the same id if submitted on multiple governors across multiple networks. This also means that in order to execute the same operation twice (on the same governor) the proposer will have to change the description in order to avoid proposal id conflicts.

Parameters

function quorum(uint256 blockNumber) external view returns (uint256)

Minimum number of cast voted required for a proposal to be successful. Note: The blockNumber parameter corresponds to the snapshot used for counting vote. This allows to scale the quorum depending on values such as the totalSupply of a token at this block (see {ERC20Votes}).

relay

function relay(address target, uint256 value, bytes data) external nonpayable

Relays a transaction or function call to an arbitrary target. In cases where the governance executor is some contract other than the governor itself, like when using a timelock, this function can be invoked in a governance proposal to recover tokens or Ether that was sent to the governor contract by mistake. Note that if the executor is simply the governor itself, use of relay is redundant.
