Prerequisites

Clone the skeleton project from git and navigate into it and install JavaScript dependencies.

git clone [email protected]:Whal3s-xyz/nft-validation-utility-skeleton.git
cd nft-validation-utility-skeleton
npm install

If you are familiar with node scripts head ofter to Get started section

Available Scripts

In the project directory, you can run:

npm start

Runs the app in the development mode. Open http://localhost:3000 to view it in your browser.

The page will reload when you make changes. You may also see any lint errors in the console

npm test

Launches the test runner in the interactive watch mode. See the section about running tests for more information.

npm run build

Builds the app for production to the build folder.

Getting started

Follow the steps and build your own utility dApp.

Install whal3s.js

npm i @whal3s/whal3s.js

Insert Utility ID

Insert your Utility ID (you copied from Whal3s App) into NftValidationUtility.jsx:15

const id = '[YOUR-UTILITY-ID]';

Create Whal3s object

Create Whal3s object in NftValidationUtility.jsx:24

const whal3s = new Whal3s();

Create Validation Utility Instance

Create Validation Utility Instance in NftValidationUtility.jsx:29

 whal3s.createValidationUtility(id).then((newUtility) => {
    newUtility.addEventListener('stepChanged', (step) => {
        setStep(step.detail.step)
    })
    setUtility(newUtility)
    setStep(newUtility.step)
})

Let users connect their wallet

Call utility.connectWallet() when the Connect-Wallet-Button in 1_ConnectWallet.jsx:10 is clicked.

<Button onClick={() => utility.connectWallet()}>Connect Wallet</Button>

Let users select one of their eligible NFTs

We already prepared an example visualization of all eligable NFTs. You just need to set the token ID that should be used.

3_SelectNft.jsx:25

if(nft.valid)
    utility.tokenId = e.target.value

Reserve usage spot

In this example we make use of the reservation feature. This is optional but can be used to block this usage spot while asking for additional data like shipping address. To do so, call if the Button in 3_SelectNft.jsx:57 is clicked.

 utility.reserveEngagement()

Claim utility

As already mentioned, we can add additional metadata to an engagement. This makes it possible to ship a completely serverless dApp. In this example (4_ClaimNft.jsx:29) we only ask for a text input you can exchange it for name and email for example. Finally you need to persist the claim. To do so, call storeEngagement on your utility object.

 utility.storeEngagement({additionalData: additionalData})

Finished

Now head over to Whal3s App and check ne freshly created engagement.

Tips and tricks

Account Center

You can customize the Wallet Configuration, like account center position, by passing a Configuration during Whal3s initialization.

const whal3s = new Whal3s({
    accountCenter: {
        desktop: {
            position: 'bottomRight', // position the account center to bottom right
        },
    }
});
