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. 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. 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.
