Create a vote signature for a Compound Governance proposal using EIP-712. This can be used to create an ‘empty ballot’ without burning gas. The signature can then be sent to someone else to post to the blockchain. The recipient can post one signature using the castVoteBySig
method.
proposalId
(string) The ID of the proposal to vote on. This is an auto-incrementing integer in the Governor contract.support
(number) A number value of 0, 1, or 2 for the proposal vote. The numbers correspond to ‘in-favor’, ‘against’, and ‘abstain’ respectively. To create an ‘empty ballot’ call this method thrice using 0
, 1
, and then 2
for this parameter.RETURN
(object) Returns an object that contains the v
, r
, and s
components of an Ethereum signature as hexadecimal strings.const compound = new Compound(window.ethereum);
(async () => {
const voteForSignature = await compound.createVoteSignature(20, 1);

Submit a Compound Governance proposal vote with a reason.
proposalId
(string) The ID of the proposal to vote on. This is an auto-incrementing integer in the Governor contract.support
