@wingriders/governance-sdk is a TypeScript SDK that provides:
- a set of helper functions for transaction building, encoding/decoding metadata and others that are used in the backend for On-Chain DAO Governance
- functions for fetching data and creating blockchain transactions that can be used in a frontend application for On-Chain DAO Governance.
If you are building a frontend application in React, check @wingriders/governance-frontend-react-sdk which is a wrapper around @wingriders/governance-sdk to simplify its usage with React.
If you are not using React to build your frontend application, you can use this library directly and it will still provide benefits for you - see the documentation below.
yarn add @wingriders/governance-sdkAll critical parts of the library have corresponding unit tests. You can execute the unit tests by running:
yarn testThe library is not specific to one deployment of the governance framework. It gets the required configuration options and deployment-specific data from the backend which acts as the configuration store. This enables the library and associated frontend application to be easy to deploy without any additional manual build steps needed.
The library acts as an SDK to support querying backend data and creating governance actions - specific on-chain transactions. It acts as a de facto glue between the backend and frontend.
We refer to blockchain transactions as actions. This library provides a function for every blockchain transaction that can be created in the On-Chain DAO Governance.
Action to create a proposal in an on-chain transaction with specific metadata.
Inputs: Proposal and poll metadata
This action creates a new proposal using an on-chain transaction. The output with the proposal creation collateral paid in governance tokens is sent to the DAO address. The proposal and poll are defined using the transaction metadata.
When creating a proposal the user has the option to create a new poll or reuse an existing one, in case a poll in the future exists.
Sample transaction metadata for creating a proposal with a new poll:
{
"op": "addProposal",
"poll": {
"op": "create",

}Action to cast a vote in an on-chain transaction.
Inputs: Proposal TX hash, selected vote option, wallet connector API
This action fetches the user’s voting power from the backend and then constructs an on-chain voting transaction. The transaction is sent to user’s own wallet and the vote itself is cast using a specific transaction metadata that lists the voting power UTxOs, the proposal TX hash, and the selected vote option.
Example metadata of a voting transaction

}
}The first key defines the poll id that the user is casting his vote for. Then globally for the poll user’s voting power and its source UTxOs are defined and then follow the user’s voting choices.
Action to conclude a proposal in an on-chain transaction. Concluding a proposal means spending the proposal UTxO that belongs to the DAO wallet.
Inputs:
- Proposal txHash
- Results (passed/failed, total votes, votes for each choice, abstained votes)
- Beneficiary - address where the collateral for creating a proposal should be sent.
This creates a transaction spending the proposal UTxO with metadata specifying the “Conclude Proposal” operation and other fields based on the proposal results. The overall result can be either that the proposal passed or failed depending on if the proposal met the participation criteria. The metadata further includes a final tally of the validated votes. The governance tokens collateral is sent to the beneficiary.
Example metadata of a transaction for concluding a proposal
{
"op": "concludeProposal",
"id": "7a70f8fe21707a2864bf3597ba73727a834f55d2ec49650871e6d571aec6acaf",
"result": "PASSED",
"choices": {
"choice1": 10,
"choice2": 20
},
"total": 40,
"abstained": 10,
"note": "..."
}Action to cancel a proposal in an on-chain transaction. Cancelling a proposal means spending the proposal UTxO that belongs to the DAO wallet.
Inputs:
- Proposal txHash
- Cancellation reason
- Beneficiary - address where the collateral for creating a proposal should be sent
This creates a transaction spending the proposal UTxO with metadata specifying the “Cancel Proposal” operation and the reason for cancellation. The governance tokens collateral is sent to the beneficiary.
Example metadata of a proposal cancellation transaction
{
"op": "cancelProposal",
"id": "7a70f8fe21707a2864bf3597ba73727a834f55d2ec49650871e6d571aec6acaf",

}This library provides well-typed fetchers (queries) for all 6 endpoints exposed by the backend, each as a separate method:
-
/params-fetchParams -
/protocolParameters-fetchProtocolParameters -
/theoreticalMaxVotingPower-fetchTheoreticalMaxVotingPower -
/userVotingDistribution-fetchUserVotingDistribution -
/proposals-fetchProposals -
/proposal-fetchProposal -
/paidFees-fetchPaidFees
To simplify the work with queries and actions, the library provides queries and actions clients.
Queries client is an object that can be created by calling createQueriesClient with URL to your governance server:
const queriesClient = createQueriesClient({governanceUrl: 'https://governance.yourapp.com'})The created queries client provides all fetchers (queries) that you can be use to fetch data in your On-Chain DAO Governance. For example querying all proposals would look like this:
const proposals = await queriesClient.fetchProposals()Actions client is an object that can be created by calling createActionsClient with these arguments:
- networkName: network for which you want to create the client (either preprod or mainnet)
- jsApi: api to users wallet - see the example below for how to create it
- protocolParameters - protocol parameters of the Cardano network, can be fetched using the queries client
- governanceVotingParams - governance parameters of your On-Chain DAO, can be fetched using the queries client
const walletConnector = new CborToJsApiWalletConnector(window.cardano.nami, {vendor: 'nami'})
const jsApi = await walletConnector.enableJs()
const governanceVotingParams = await queriesClient.fetchVotingParams()
const protocolParameters = await queriesClient.fetchProtocolParameters()
const actionsClient = await createActionsClient({
networkName: NetworkName.PREPROD,
jsApi,
governanceVotingParams,
protocolParameters,
})The created actions client provides functions for building all transactions for your On-Chain DAO Governance. For example building a transaction that creates a new proposal would look like this:
const builtTransaction = actionsClient.buildCreateProposal(...params)
