LXDAO SBT-based Membership System Contract

This is the LXDAO SBT-based Membership System Contract project.

By using this contract, any Dao can issue a unique soul-bound token to community members.

Step 1, fill the .env variable

.env.example explanation

• API_URL is the url of the archive node used to connect, we recommend using Alchemy/infura.
• PRIVATE_KEY is the wallet private key, used for generating signature and pass to contract to verify. It is recommended to create a new empty wallet.
• ETHERSCAN_API_KEY is the api key create from etherscan used to access ethereum data.
• SIGNER is the public address of the wallet used to verify mint and updateMetadata call.

after all , modify the .env.example file to .env

Step 2,Run unit tests

npm install
npm run test

Step 3,Deploy

npm run compile
npm run deploy:rinkeby

When your deployment is complete, the SIGNER in the .env file will be the first SIGNER of the contract (which you can change later by using setSigner)

Step 4,Mint

When a new member was added to the community, the signature of SIGNER is required, and the signature implementation function is as follows

import bs58 from "bs58";
import ethers from "ethers";
import * as dotenv from 'dotenv';
dotenv.config();

let provider = new ethers.providers.JsonRpcProvider(process.env.API_URL)
let originalSigner = new ethers.Wallet(process.env.PRIVATE_KEY, provider);//get Signer object

const ipfsHash = "Your ipfs Hash";
const builderAddress = "your wallet address"


async function getSignature() {
    const bytes = bs58.decode(ipfsHash).slice(2);

    const hash = ethers.utils.keccak256(
        ethers.utils.defaultAbiCoder.encode(["bytes", "address"], [bytes, builderAddress]),
    );
    const hashBytes = ethers.utils.arrayify(hash);

    const signature = await originalSigner.signMessage(hashBytes);
    console.log("Signature:",signature)
    return signature
}

getSignature()
    

Member Status intro

1. The Pending is the original status of the buidler which can't do everything before mint success.
2. The Active status means that the buidler finished onboarding process and call mint success.
3. Buidler can update metadata on official website themselves in Active status anytime.
4. If the buidler quit from community, the status should be set to Archived.
5. The buidler's status can be set to Suspended by committee for security reasons, reactivate is possible after resolve it.

What is LXDAO?

LXDAO is an R&D-focused DAO in Web3. Our mission is: To bring together buidlers to buidl and maintain valuable projects for Web3, in a sustainable manner.
