Proposals

Governance proposals submit actions for the community to vote on. The deposit is automatically fetched from protocol parameters and refunded to your reward account when the proposal is finalized.

Submitting a Proposal

import { Anchor, GovernanceAction, RewardAccount, preprod, Client } from "@evolution-sdk/evolution"

const client = Client.make(preprod)
  .withBlockfrost({
    baseUrl: "https://cardano-preprod.blockfrost.io/api/v0",
    projectId: process.env.BLOCKFROST_API_KEY!
  })
  .withSeed({ mnemonic: process.env.WALLET_MNEMONIC!, accountIndex: 0 })

declare const governanceAction: GovernanceAction.GovernanceAction
declare const rewardAccount: RewardAccount.RewardAccount
declare const anchor: Anchor.Anchor

const tx = await client
  .newTx()
  .propose({
    governanceAction,
    rewardAccount,
    anchor
  })
  .build()

const signed = await tx.sign()
await signed.submit()

The govActionDeposit is deducted automatically during transaction balancing.
