Dao contract guide

We can create a Dao contract for an user using the DaoRegister contract deployed by Relation Protocol. A dao contract can provide a Dao with member management functions. Both the DaoRegister contract and the Dao contract implement the contract interface defined by the Contract Standard.

Construct a Contract object

Via Relation Protocol's resource list, you can acquire the contract address and abi file of DaoRegister and DaoWithSign, and the abi file of Dao contract. As for the address of a Dao contract, you need to query it through DaoRegister.

  • Construct a DaoRegisterContract object:

import { ethers, providers } from 'ethers'

const getDaoRegisterContractInstance = () => {
  // DaoRegister's contract address
  const contractAddress = '0xAC0f863b66173E69b1C57Fec5e31c01c7C6959B7'
  const provider = new providers.Web3Provider(window.ethereum)
  const signer = provider.getSigner()
  const contract = new ethers.Contract(contractAddress, daoRegisterAbi, signer)
  return contract
}

const getDaoWithSignContractInstance = () => {
    // DaoRegister's contract address
    const contractAddress = '0xAC0f863b66173E69b1C57Fec5e31c01c7C6959B7'
    const provider = new providers.Web3Provider(window.ethereum)
    const signer = provider.getSigner()
    const contract = new ethers.Contract(contractAddress, daoWithSignAbi, signer)
    return contract
}

How to call a contract

DaoRegister

  1. Deploy a Dao contract

const daoRegisterContract = getDaoRegisterContractInstance()
const daoName = 'my-first-dao';
const accounts = await ethereum.request({ method: 'eth_requestAccounts' })
await (
    await daoRegisterContract.deployDaoContract(accounts[0],daoName)
).wait()

  1. Query the list of Daos created by an user

You can get the list of Daos created by a user by using a traversal process to go through the tokens held on the DaoRegister contract by said user.

const addr = '0x000...';
const daoRegisterContract = getDaoRegisterContractInstance()

const balance = await daoRegisterContract.balanceOf(addr);
var daoContractAddress = [];
for(var i = 0; i < balance; i++){
    const tokenId = await daoRegisterContract.tokenOfOwnerByIndex(addr,i);
    const {daoOwner,contractAddress} = await daoRegisterContract.daoOf(tokenId);
    daoContractAddress.push(contractAddress);
}

  • Construct a DaoContract Object


const getDaoContractInstance = (contractAddress) => {
  const provider = new providers.Web3Provider(window.ethereum)
  const signer = provider.getSigner()
  const contract = new ethers.Contract(contractAddress, daoRegisterAbi, signer)
  return contract
}

Dao

  1. Query the administrator of a Dao

const daoContractAddress = '0x000...';
const daoContract = getDaoContractInstance(daoContractAddress)
const ownerAddress = await daoContract.ownerOfDao();

  1. Configure the DaoURI

The administrator of a Dao can assign description and avatar for a Dao, with the description and avatar stored on Arweave. We use the data format for this as follows:

{
  "avatar": "${The avatar of DAO}",
  "description": "${The description of DAO}"
}

The transaction hash of the upload will be stored in the contract as DaoURI

const daoURI = 'hX_Mne1...';
const daoContractAddress = '0x000...';
const daoContract = getDaoContractInstance(daoContractAddress)
await (
    await daoContract.setDaoURI(daoURI)
).wait()

  1. Query the DaoURI

const daoContractAddress = '0x000...';
const daoContract = getDaoContractInstance(daoContractAddress)
const daoURI = daoContract.daoURI();

  1. Modify a Dao's name

The administrator of a Dao can modify its name.

const daoContractAddress = '0x000...';
const daoContract = getDaoContractInstance(daoContractAddress)
const daoURI = daoContract.daoURI();
const daoName = 'new-name';
await (
    await daoContract.setName(daoName)
).wait()

  1. Query a Dao's name

const daoContractAddress = '0x000...';
const daoContract = getDaoContractInstance(daoContractAddress)
const daoName = daoContract.name();

  1. When an administrator adds a member to a Dao

An administrator can add specific addresses to a Dao.

const daoContractAddress = '0x000...';
const daoContract = getDaoContractInstance(daoContractAddress)
const members = ['0x001...','0x002...','0x003...'...];
await (
    await daoContract.addMember(members)
).wait()

  1. Open Access(Optional for a Dao)

An administrator of a Dao can set it to Open Access, meaning that anyone can join the Dao.

const daoContractAddress = '0x000...';
const daoContract = getDaoContractInstance(daoContractAddress)
await (
    await daoContract.setFreeJoin(true)
).wait()

  1. When a user joins a Dao

With Open Access enabled by the administrator of a Dao, users can join the Dao freely.

const daoContractAddress = '0x000...';
const daoContract = getDaoContractInstance(daoContractAddress)
await (
    await daoContract.join()
).wait()

  1. Remove a Dao member

An administrator can remove a member from a Dao. Also, users can leave a Dao freely.

const daoContractAddress = '0x000...';
const daoContract = getDaoContractInstance(daoContractAddress)
const addr = '0x001...';
await (
    await daoContract.remove(addr)
).wait()

  1. Query the list of Dao members

You can get a whole list of Dao members with a traversal process to find all the token owners of said Dao.

const daoContractAddress = '0x000...';
const daoContract = getDaoContractInstance(daoContractAddress)
const memberCount = await daoContractAddress.totalSupply();
var memberList = [];
for(var i = 0; i < memberCount;i++){
    const tokenId = await daoContract.tokenByIndex(i);
    const member = await daoContract.ownerOf(tokenId);
    memberList.push(member);
}

  1. Configure the DaoURI(Gas fee can be paid by someone else)

The administrator of a Dao can assign description and avatar to a Dao, with the content stored on Arweave. The format of the content should be:

{
  "avatar": "${The avatar of DAO}",
  "description": "${The description of DAO}"
}

The administrator signs against the transaction hash and constructs a parameter to be posted on the blockchain. Any address can use this parameter to initiate a transaction on the blockchain, with the gas fee paid by said address.
