Token - Gating - SDK

A Simple and Modern SDK For Implementing Token - Gating in your webpage , in just few steps.

Demo

Introduction

Website owners can verify the ownership of NFTs and Tokens in the users wallet , and accordingly grant or restrict the access to a Webpage with the help of this SDK.

It is Ready to use out of the Box , for all type of Applications , Next , React, etc. with just simple configurations steps , can be followed in the tutorial below.

Features

1 . Supports all the Major Networks (Mainnet) :

• Ethereum
• Polygon
• Optimism
• Arbitrum One

2 . All wallets supported :

• Metamask
• Rainbow
• Wallet Connect
• Coinbase

3 . Easy to set up and integrate with just 3 steps

4 . Highly Customizable , Configure access based on multiple conditions

Installation

Install token-gating-sdk from CLI , in your project's root directory.

  npm install token-gating-sdk

  or

  yarn add token-gating-sdk

NOTE : Installation might take 2-3 minutes sometime , as there are lot of dependencies included in the package .

Types

There are 3 kinds of Wrappers as follow :

• NextGatingWrapper for Next.js
• ReactGatingWrapper for React.js
• UniversalGatingWrapper for other applications

Usage

For Next.js applications

1. Import the Next Gating Wrapper and styles

Under _app.tsx

import { NextGatingWrapper } from "token-gating-sdk";
import "@rainbow-me/rainbowkit/styles.css";

Wrapper Inputs

config

Create the config file as the tutorial below

type configDataType = {
  path: string,
  methodName: methods,
  network: networks,
  data: {
    contractAddress: string,
    tokenId?: string,
    amount?: number,
  },
}[];

Parameter	Type	Description
config	configType	Required. configData

ALCHEMY API KEY

Get an API key from Alchemy

const API_KEY: any = process.env.ALCHEMY_API_KEY;

Parameter	Type	Description
alchemyApiKey	string	Required. Api key from Alchemy

2. Import inputs

Under _app.tsx

import { configData } from "../config/config";
const API_KEY: any = process.env.NEXT_PUBLIC_ALCHEMY_API_KEY;

3. Wrap the App with the Next Wrapper as follows

Under _app.tsx

export default function App({ Component, pageProps }: AppProps) {
  return (
    <NextGatingWrapper config={configData} alchemyApiKey={API_KEY}>
      <Component {...pageProps} />
    </NextGatingWrapper>
  );
}

Andd !! BOOM ✨ , You just Token Gated your website

NOTE:

For other Wrapper Types , the guide is similar , just the import wrapper is changes to implement the functionality

Run

To run the project , run local dev command

In Next Apps

  npm run dev

How to create the Config File ??

This is a very important step , where you can configure , that which page , should implement what conditions or requirements , to allow the access to the end User.

Create specific config for each page type , with the following format :

configDataType = {
  path: string;  // path name
  methodName: methods;  // methods
  network: networks; // network
  data: {
    contractAddress: string;  // contractAddress of Token or NFT
    tokenId?: string;  // Token Id of the NFT (if req.)
    amount?: number;  // Amount of tokens (if req.)
  };
}[]

Methods

There are currently 4 methods available , as follows :

• NFTWithTokenID for NFT with a Specific Token ID from a collection, E.g. BAYC No. 8378

Need to add contractAddress and tokenID of the NFT

{
    path: "/page",
    methodName: methods.NFTWithTokenID,
    network: networks.Ethereum,
    data: {
      contractAddress: "0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D",
      tokenId:"8378",
    },
  },

• NFTCollection for NFT from a particular NFT Collection, E.g. BAYC

Need to add contractAddress of NFT Collection

{
    path: "/page",
    methodName: methods.NFTCollection,
    network: networks.Ethereum,
    data: {
      contractAddress: "0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D"
    },
  },

• TOKEN for a particular Token , E.g. USDC

Need to add contractAddress of Token

{
    path: "/page",
    methodName: methods.TOKEN,
    network: networks.Ethereum,
    data: {
      contractAddress: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48"
    },
  },

• TOKENwithAmount for an amount of a Particular token , E.g. 100 USDC

Need to add contractAddress and amount of the token

{
    path: "/page",
    methodName: methods.TOKEN,
    network: networks.Ethereum,
    data: {
      contractAddress: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
      amount: 100000000,
    },
  },

These can be accessed by importing methods

export enum methods {
  "NFTWithTokenID",
  "NFTCollection",
  "TOKEN",
  "TOKENwithAmount",
}

Networks

We Support 4 Mainnets currently:

• Ethereum
• Optimism
• Polygon
• Arbitrum One

These can be accessed by importing networks

export enum networks {
  "Ethereum",
  "Optimism",
  "Polygon",
  "Arbitrum One",
}

Example

Here is an example config File , for all the 4 types of Methods. Refer the same for more info -

import { configType, methods, networks } from "token-gating-sdk";

export const configData: configType = [
  {
    path: "/privatenft",
    methodName: methods.NFTWithTokenID,
    network: networks.Ethereum,
    data: {
      contractAddress: "0x57f1887a8BF19b14fC0dF6Fd9B2acc9Af147eA85",
      tokenId:
        "5691999065095808972681467169397940732013218209247626737760195198340626795922",
    },
  },
  {
    path: "/privatecollection",
    methodName: methods.NFTCollection,
    network: networks.Ethereum,
    data: { contractAddress: "0x57f1887a8BF19b14fC0dF6Fd9B2acc9Af147eA85" },
  },
  {
    path: "/privatetoken",
    methodName: methods.TOKEN,
    network: networks.Ethereum,
    data: { contractAddress: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48" },
  },
  {
    path: "/privatetokenamount",
    methodName: methods.TOKENwithAmount,
    network: networks.Ethereum,
    data: {
      contractAddress: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
      amount: 100000000,
    },
  },
];
