SBT Membership badges

With Masa, you can build a membership program using non-transferable, soulbound badges. For example, a web3 gaming platform with active Discord communities can issue a membership badge to their longest-standing community members who will get perks, and access to exclusive offers, and souldrops. In this guide, we cover the steps for setting up a membership program using SBT Badges.

Using soulbound membership badges you can

  • Mint a non-transferable, soulbound badge that represents a user’s community membership as proof-of-status.
  • Use soulbound membership badges as unique identifiers, you can give badge holders different access to perks and rewards.
  • Use soulbound membership badges as unique identifiers, you can market to a specific group of users with membership badge SBTs in their wallets.

For example:

  • Loyalty Program: you can mint various tiers and types of “VIP / OG badges” to represent a user’s loyalty status in a tier-based membership program.
  • Ambassador Program: you can mint various tiers and types of “contributor/moderator/ambassador badges” to represent a member’s community status
  • Employee Program: you can mint various membership badges to reward employees, such as “Employee #1 / #2 / #3”

yarn add @masa-finance/masa-sdk --save

Install via npm​

npm i @masa-finance/masa-sdk --save

Configure Masa SDK​

A guide how to set up the Masa SDK can be found here: Masa SDK

Deploy SBT Badge contract​

In this guide we will use an Authority SBT that can be minted (dropped) directly to a users wallet without any user interaction with web3.

caution

You will need a minimum of 0.10 of your testnet asset to deploy a contract. This will either be Goerli ETH, Base ETH, Mumbai MATIC, Alfajores Celo, or Testnet BNB.

console.log("Deploying ASBT contract\n");

const name = await readLine("Enter the name of the SBT: ");
const symbol = await readLine("Enter the ticker of the SBT: ");
const baseTokenUri = await readLine("Enter the URL for the metadata image: ");
const adminAddress = await readLine(
  `Admin address (leave empty to use: '${await masa.config.wallet.getAddress()}'): `
);

const address = await masa.sbt.deployASBT(
  name,
  symbol,
  baseTokenUri,
  adminAddress
);

if (!address) {
  console.error("Deployment failed!");
}

Mint SBT Badge​

It is simple to mint an SBT using the contract address from your deployment - we will use the one we just deployed 0x4d527F3eFD9dCf5fF44284FfB9fe22C6bdc2Da20 and mint an SBT Badge to the receiver 0xb3EAE0c0d3e09241a48485D7fDE226587A4E4461.

const { mintASBT } = await masa.sbt.connect(contractAddress);
await mintASBT(receiver);
