Instructions for dApp integration with 3rd wallets that support XDC network such as: metamask, nabox, onto, dcent etc

First step you need to install:

For Nodejs:

npm i xdc3

For web app

<script src="https://cdn.jsdelivr.net/npm/xdc3@1.3.13416/dist/web3.min.js"></script>

You need to read more walletconnect to can do work with dcent or wallets that support walletconnect
https://docs.walletconnect.com/1.0/quick-start/dapps/web3-provider

Step 2:

var adapters = ['metamask', 'xdcpay', 'nabox', 'dcent', ];
var connector;

if (adapter == 'metamask')
        {
            window.web3 = new Web3(ethereum);

            window.ethereum.on('chainChanged', () => {
                document.location.reload();
            });

            window.ethereum.on('accountsChanged', () => {
                 document.location.reload();
            });
            await web3.eth.requestAccounts();
        }

        if (adapter == 'xdcpay'){
            window.web3 = new Web3(window.xdc);
        }

        if (adapter == 'nabox'){
            window.web3 = new Web3(window.NaboxWallet);
            await web3.eth.requestAccounts();
        }

        if (adapter == 'onto')
        {
            window.web3 = new Web3(window.onto);
            await web3obj.eth.requestAccounts();
        }

        if (adapter == 'dcent'){
            var WalletConnectProvider = window.WalletConnectProvider.default;
            connector = new WalletConnectProvider({
                  rpc: {
                    50: "https://rpc.xinfin.network"
                  },
                  qrcodeModalOptions: {
                    mobileLinks: [
                      "dcent"
                    ],
                    desktopLinks: [
                      "dcent"
                    ]
                  }
            });

            await connector.enable();
            window.web3 = new Web3(connector);
        }

Hope it helps, and we'll update when there's an integration for new wallets.
Thanks!

.xdc domains releases SDK libraries for projects that need to integrate .xdc into their wallets and dapps.

XDC Web3 Domains — Wed, 24 Aug 2022 08:50:03 +0000

We are XDC Web3 Domain (.xdc). We are happy to partner with projects (wallets, dapps) on XDCNetwork to integrate .xdc into their projects.

For dApp: When you use DApps integrated with .xdc domains, your .xdc account will be visible anywhere on DApps instead of a long wallet address.

For Wallet: When the wallet integrates .xdc instead of a long wallet address. Then sending and receiving tokens/NFTs is really as simple as just pasting the .xdc domain. It's more secure, avoid confusion and really stress free from having to check long wallet addresses.

We now have NPMJS and RestfulAPI available for integration, see details below:

Github: https://github.com/XDCWeb3Domains

Npmjs: https://npmjs.com/package/xdcdomainjs

What should we pay attention to when deploying XRC721 smart contract on XDCNetwork?

XDC Web3 Domains — Mon, 15 Aug 2022 09:05:49 +0000

From our practical experience when deploying xdcdomain on XDC Network, we realize the following precautions are needed to ensure your contract can be displayed well on Blocksscan and Dcent wallet:

1. Avoid using TokenId with too long numbers:
We used hashname algorithm to convert text to unit256 and used it as tokenId, everything works perfectly, data is fully stored on blockchain. However, explorer.xinfin.network cannot display these transactions. Reason:

Domain: blocksscan.xdc
tokenId:77979873881399215098531253405261912846024336523392861649759436500022565154832

tokenId is a number that is too long, so explorer may not be fully supported.

Advice: Please keep it simple and use Counters.sol of OpenZeppelin to solve the creation is to store tokenId with increment variable.

https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/utils/Counters.sol

2. Returns url format when calling tokenURI function:

function tokenURI(uint256 _tokenId) public view returns (string) {
return Strings.strConcat(
baseTokenURI(),
_tokenId
);
}

Make sure that calling the tokenURI function with the tokenId parameter always returns the url format "https://yourhost.com/tokenId"

If you return base64 and store the entire json of the metatdata when calling tokenURI, surely blocksscan and dcent will not fully support and lead to not being able to read the metadata.

3. Metadata needs to be standards compliant:

See the metadata-standard here: https://docs.opensea.io/docs/metadata-standards

Note the image parameters are very important for dcent wallet to show your NFT. So try to store both the image path and the base64 of the image if possible.

image: This is the URL to the image of the item. Can be just about any type of image (including SVGs, which will be cached into PNGs by OpenSea), and can be IPFS URLs or paths. We recommend using a 350 x 350 image.

image_data: Raw SVG image data, if you want to generate images on the fly (not recommended). Only use this if you're not including the image parameter.

4. "xdc" string will be converted to 0x when you write to smart contract

So the solution when you need to display the correct xdc string, you need to hard fix it in the smart contract or set the variable to bytes.

Thanks! Hope to be of help to you!

XDC Web3 Domains (.xdc) - Own Your Blockchain Domains

Building Identity on blockchain with .xdc domains

NFT domain is not only a wallet name, it also has functions of a website address. As a website, the users can type in their NFT domain name in a compatible browser, it will show users the website content that they put there. As a cryptocurrency wallet, they can use that same domain name to send and receive cryptocurrencies.

In the past, whenever cryptocurrency holders wanted to send crypto to another person, they needed their wallet address, which consists of a long string of letters and numbers. Today, all they need is a domain name, making it easier than ever to send and receive cryptocurrencies.

REPLACE A CRYPTO ADDRESS WITH A DOMAIN NAME

In the past, whenever you sent crypto to another person, you needed their wallet address, which consists of a long string of letters and numbers. Today, all you need is a domain name, making it easier than ever to send and receive cryptocurrencies. It’s security, privacy and safety.

ONE-TIME REGISTRATION FEE, NO RENEWAL FEES

XDC domains are not rented, after buying a .xdc domain, it is yours forever, no one can request any renewal fees from you. Domains can be stored in your wallet, like cryptocurrency and only you can control it.

TRANSACTIONS WILL BE SIMPLIFIED

A crypto wallet address is made up of a series of random numbers and letters like xdccee6f2d7d0c95052161387b04c09880744065e, that makes transfering cryptocurrency from one wallet to another more difficult. With a .xdc domain, it becomes much easier when your friends can send you money to your domain address rather than copying lots of random numbers and letters.

SUPPORT ENDLESS CURRENCIES AND TOKENS

Another advantage of xdc domain is that many currencies are accepted and can receive tokens and coins. Some of the most popular accepted cryptocurrencies and tokens are: BTC, ETH, Solana, etc.

DOMAIN IS YOURS AND ONLY YOU CAN CONTROL IT

.xdc domains are not centralized, after purchasing them, they are yours for life and you can also control it fully without third parties dictating rules to you.
