Governance

Evolution SDK supports Cardano's Conway-era governance system (CIP-1694). Register as a Delegated Representative (DRep), vote on governance actions, submit proposals, and manage Constitutional Committee credentials — all through the transaction builder.

📄️DRep Registration

Register, update, and deregister as a Delegated Representative

📄️Vote Delegation

Delegate your governance voting power to a DRep

📄️Voting

Cast governance votes on proposals

📄️Proposals

Submit governance proposals on Cardano

📄️Committee Operations

Authorize hot credentials and resign from the Constitutional Committee

Governance Roles

Role	Description	Operations
DRep	Delegated Representative who votes on behalf of delegators	Register, update, deregister, vote
Committee Member	Constitutional Committee member	Authorize hot key, resign
Stake Pool Operator	Pool operators vote on specific governance actions	Vote (key-hash only)
ADA Holder	Delegate voting power to a DRep	Delegate to DRep

Quick Example

import { Credential, 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 drepCredential: Credential.Credential

const tx = await client.newTx().registerDRep({ drepCredential }).build()

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

Script-Controlled Governance

All governance operations support script-controlled credentials. Provide a redeemer when the credential is a script hash:

import { Credential, Data, 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 scriptDrepCredential: Credential.Credential
declare const governanceScript: any

const tx = await client
  .newTx()
  .registerDRep({
    drepCredential: scriptDrepCredential,
    redeemer: Data.constr(0n, [])
  })
  .attachScript({ script: governanceScript })
  .build()

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