Governor Votes Comp

Extension of {Governor} for voting weight extraction from a Comp token. Available since v4.3.

Methods

BALLOT_TYPEHASH

function BALLOT_TYPEHASH() external view returns (bytes32)

Returns

Name	Type	Description
_0	bytes32	undefined

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 = For, 1 = Against, 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. NOTE: The string can be decoded by the standard https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams[URLSearchParams] JavaScript class.

execute

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

See {IGovernor-execute}.

values	uint256[]	undefined
calldatas	bytes[]	undefined
descriptionHash	bytes32	undefined

Returns

Name	Type	Description
_0	uint256	undefined

getVotes

function getVotes(address account, uint256 blockNumber) external view returns (uint256)

Read the voting weight from the token's built in snapshot mechanism (see {IGovernor-getVotes}).

Parameters

Name	Type	Description
account	address	undefined
blockNumber	uint256	undefined

Returns

Name	Type	Description
_0	uint256	undefined

hasVoted

function hasVoted(uint256 proposalId, address account) external view returns (bool)

module:voting

Returns weither account has cast a vote on proposalId.

Parameters

Name	Type	Description
proposalId	uint256	undefined
account	address	undefined

Returns

Name	Type	Description
_0	bool	undefined

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 RLC 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 accross 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

Name	Type	Description
targets	address[]	undefined
values	uint256[]	undefined
calldatas	bytes[]	undefined
descriptionHash	bytes32	undefined

Returns

Name	Type	Description
_0	uint256	undefined

votingPeriod

function votingPeriod() external view returns (uint256)
