Enable human-readable addresses in Unity

You can integrate the Decentraweb name resolver into your Unity game with MetaMask SDK installed. Decentraweb maps human-readable names to machine-readable identifiers, such as Ethereum addresses. Integrating Decentraweb into your game allows users to interact with addresses in a more user-friendly way.

Prerequisites

MetaMask SDK set up in your Unity game.

Initialize the integration wrapper

Use the newDWebAPIWrapper() method to configure and initialize a C# integration wrapper, which acts as a bridge between the MetaMask Unity SDK and the Decentraweb name resolver API. This method initializes the wrapper with necessary configuration parameters, including authentication details required to interact with the Decentraweb name resolver API.

// Initialize the wrapper.
var apiWrapper = newDWebAPIWrapper();

Convert a name to an Ethereum address

Use the ResolveNameAsync(name) method to convert a human-readable name to the corresponding Ethereum address.

The C# integration wrapper translates the request into a format that the Decentraweb name resolver API can understand, and sends the translated request to the name resolver using a standard HTTP POST request.

The name resolver processes the request and responds with the Ethereum address.

Method

// Initialize the wrapper.
var apiWrapper = newDWebAPIWrapper();

// Get the user's human-readable name.
var name = "user.dweb";

// Resolve the name to an Ethereum address.
var address = await apiWrapper.ResolveNameAsync(name);

JSON response

{
  "success": true,
  "result": "0xcB3E45F337Dd3Beeba98F5F9F9A16e9cD152cC86"
}

Convert an Ethereum address to a name

Use the GetNameAsync(address) method to convert an Ethereum address to the corresponding human-readable name.

The C# integration wrapper translates the request into a format the Unity SDK can understand, and sends the translated request to the SDK.

The SDK processes the request and responds with the human-readable name.

Method

// Initialize the wrapper.
var apiWrapper = newDWebAPIWrapper();

// Get the user's address.
var address = "0xcB3E45F337Dd3Beeba98F5F9F9A16e9cD152cC86"

// Resolve the address to a human-readable name.
var name = await apiWrapper.GetNameAsync(address)

JSON response

{
  "success": true,
  "result": {
    "name": "lordsats",
    "confirmed": true
  }
}

Example

The following is an example of using the Unity SDK Decentraweb integration to create a transaction:

public async Task FormTransactionAsync()
{
  // Initialize the wrapper.
  var apiWrapper = new DWebAPIWrapper();

  // Get the user's human-readable name.
  var name = "user.dweb";

  // Resolve the name to an Ethereum address.
  var address = await apiWrapper.ResolveNameAsync(name);

  // Form the transaction.
  var transaction = new Transaction
  {
    To = address,
    Value = 1.0m,
    Gas = 21000
  };

  // The rest of the transaction formation code.
}
