Getting Started

Create an instance of the XRC20 token:

Using XDCSDKLib;
IXRC721Token xRC721Token = new XRC721Token();

Read Methods

name

var name=  await xRC721Token.GetTokenName (“contractAddress”, “BlockchainNetworkUrl”);

symbol

var symbol=  await xRC721Token. GetSymbol (“contractAddress”, “BlockchainNetworkUrl”);

decimal

var decimal=  await xRC721Token. GetDecimal (“contractAddress”, “BlockchainNetworkUrl”);

TotalSupply

var supply= await xRC721Token. GetTotalSupply (“contractAddress”, “BlockchainNetworkUrl”);

balanceOf

var balanceOf=  await xRC721Token. GetBalanceOf (“contractAddress”, “ownerAdddress”, “BlockchainNetworkUrl”);

tokenURI

var tokenURI=  await xRC721Token. GetTokenURI (“contractAddress”, ”tokenId”,“BlockchainNetworkUrl”);

ownerOf

var ownerOf=  await xRC721Token. GetOwnerOf (“contractAddress”, ”tokenId”,“BlockchainNetworkUrl”);

tokenOwnerbyIndex

var tokenOwnerbyIndex =  await xRC721Token. GetTokenOfOwnerByIndex (“contractAddress”, ”ownerAddress”,”Index”,“BlockchainNetworkUrl”);

TokenByIndex

var tokenIndex =  await xRC721Token. GetTokenByIndex (“contractAddress”, ” tokenByIndex”,“BlockchainNetworkUrl”);

GetApproved

var getApproved=  await xRC721Token. GetApproved (“contractAddress”, ”tokenId”,“BlockchainNetworkUrl”);

supportsInterface

var supportsInterface=  await xRC721Token. SupportsInterface (“contractAddress”, byte[] InterfaceId ,“BlockchainNetworkUrl”);

Write Methods

approve

var approve=  await xRC721Token. Approve (“contractAddress”, “addresTo”,“tokenId”“BlockchainNetworkUrl”,”ownerPrivateKey”);

SetApprovalforAll

var setApproveAll=  await xRC721Token. SetApprovalforAll (“contractAddress”, “addresTo”,approved “BlockchainNetworkUrl”,”ownerPrivateKey”);

IsApprovalforAll

var IsApprovalforAll=  await xRC721Token. IsApprovalforAll (“contractAddress”, “OwnerAddress”,“operatorAddress”,“BlockchainNetworkUrl”,”ownerPrivateKey”);

Transferfrom

var tranFrom=  await xRC721Token. TransferFrom (“contractAddress”, “addresTo”,“tokenId”“BlockchainNetworkUrl”,”ownerPrivateKey”);

SafeTransferFrom

var SafeTransferFrom =  await xRC721Token. SafeTransferFrom (“contractAddress”,” fromAddress”,“addresTo”,“tokenId”“BlockchainNetworkUrl”,”ownerPrivateKey”);

Create an XRC account

Create the XRC account using the following code:

IAccount account=new Account();

account.CreateAccount(“password”,”workingDirectory”);

var privateKey = account.PrivateKey;

var accountAddress= account.AccountAddress;

Private Key can also be accessed from the working directory that is saved in the system by the following method:

Var privateKey= account.GetPrivateKey(“nameoffile”,”workingdirectory”,”password”);

How to Publish the XDCSDKWebApi into the server?

  1. Install the SDK .net core 3.1 version on the server and publish the supported DLL files into the virtual directory of the server. We pushed all the supported DLLs for publishing the XDCSDKWebAPI into the branch PublishDllForXDCWebApi.

  2. As per requirements, change the URL of BlockNetworkChain into the appsettings.json file.

"XDCSDKUrl": {
"Url": "
https://rpc.apothem.network/
"
}

Hardware requirements:

  • Operating system: Windows 10 or upper version, windows server latest.

  • Memory (RAM): minimum 8 GB

  • Processor: Core I3 or above.
