Voting

DReps, Constitutional Committee members, and Stake Pool Operators can vote on governance actions. Evolution SDK's vote operation submits voting procedures in a transaction.

Casting a Vote

import { ,  } from "@evolution-sdk/evolution"

const  = ({
  : "preprod",
  : { : "blockfrost", : "https://cardano-preprod.blockfrost.io/api/v0", : ..! },
  : { : "seed", : ..!, : 0 }
})

declare const : .

const  = await 
  .()
  .({  })
  .()

const  = await .()
await .()

Voter Types

Voter	Credential Type	Script-Controlled?
DRep	Key hash or script hash	Yes
Constitutional Committee	Hot credential (key or script)	Yes
Stake Pool Operator	Pool key hash	No (key-hash only)

Script-Controlled Voting

For DReps or Committee members with script credentials, provide a redeemer:

import { , ,  } from "@evolution-sdk/evolution"

const  = ({
  : "preprod",
  : { : "blockfrost", : "https://cardano-preprod.blockfrost.io/api/v0", : ..! },
  : { : "seed", : ..!, : 0 }
})

declare const : .
declare const : any

const  = await 
  .()
  .({
    ,
    : .(0n, []), // Vote purpose validator
    : "drep-vote"
  })
  .({ :  })
  .()

const  = await .()
await .()

The builder automatically detects script-controlled voters and will fail if a redeemer is required but not provided.
