Snapshot 投票流程

1. 查询当前活跃投票

query Proposals {
  proposals(first: 20, skip: 0, where: { space_in: ["lido-snapshot.eth"], state: "active" }, orderBy: "created", orderDirection: desc) {
    id
    title
    body
    choices
    start
    end
    snapshot
    state
    author
    type
    app
    space {
      id
      name
    }
  }
}

1. 查询投票详情

query Proposal($id: String!) {
  proposal(id: $id) {
    id
    ipfs
    title
    body
    discussion
    choices
    start
    end
    snapshot
    state
    author
    created
    plugins
    network
    type
    quorum
    symbol
    privacy
    validation {
      name
      params
    }
    strategies {
      name
      network
      params
    }
    space {
      id
      name
    }
    scores_state
    scores
    scores_by_strategy
    scores_total
    votes
    flagged
  }
}

{
  "id": "<proposal id>"
}

1. 检查是否投过票

query Votes(
  $id: String!,
  $first: Int,
  $skip: Int,
  $orderBy: String,
  $orderDirection: OrderDirection,
  $reason_not: String,
  $voter: String,
  $space: String,
  $created_gte: Int
) {
  votes(
    first: $first,
    skip: $skip,
    where: {
      proposal: $id,
      vp_gt: 0,
      voter: $voter,
      space: $space,
      reason_not: $reason_not,
      created_gte: $created_gte
    },
    orderBy: $orderBy,
    orderDirection: $orderDirection
  ) {
    ipfs
    voter
    choice
    vp
    vp_by_strategy
    reason
    created
  }
}

{
    "id":"<proposal id>",
    "voter":"<your address>"
}

{"data":{"votes":[]}}

1. 根据 strategies 检查投票权

{
   "method":"get_vp",
   "params":{
      "space":"lido-snapshot.eth",
      "delegation":false,
      "network":"1",
      "snapshot":17834886,
      "strategies":[...],
      "address":"<your address>"
   }
}

{
    "jsonrpc": "2.0",
    "result": {
        "vp": 0,
        "vp_by_strategy": [
            0,
            0
        ],
        "vp_state": "final"
    },
    "id": null,
    "cache": true
}

1. 签名 (EIP-712)

const message = {
  "domain":{
     "name":"snapshot",
     "version":"0.1.4"
  },
  "types":{
     "Vote":[
				{ name: 'from', type: 'address' },
        { name: 'space', type: 'string' },
        { name: 'timestamp', type: 'uint64' },
        { name: 'proposal', type: 'bytes32' },
        { name: 'choice', type: 'uint32' },
        { name: 'reason', type: 'string' },
        { name: 'app', type: 'string' },
        { name: 'metadata', type: 'string' }
     ]
  },
  "message":{
     "space":"•8099.eth",
     "proposal":"0xf5a5d1339b96c787f1e8ad69655d62c4d22cfdda40bb2e11e6687c22183a81ad",
     "choice":1,
     "app":"snapshot",
     "reason":"",
     "metadata":"{}",
     "from":"<your address>",
     "timestamp":1691163048
  }
};

const signer = new ethers.Wallet(PRIVATE_KEY);
const sig = await signer._signTypedData(message.domain, message.types, message.message);
console.log(sig);

1. 提交投票信息

{
  "address":"<your address>",
  "sig":"<sig>",
	"data": {<第三步中的整个message对象>}
}

{
    "id": "",
    "ipfs": "",
    "relayer": {
        "address": "",
        "receipt": ""
    }
}
