Requirements

This package supports the following build targets and Unity versions:

Unity Version	Windows	Mac OS	Linux	Android	iOS	WebGL
2020.3	❌	❌	❌	❌	❌	❌
2021.3	✅	✅	✅	✅	✅	✴️
2022.2	✅	✅	✅	✅	✅	✴️

• ❌ Not supported. Use at your own risk.

Common Usages

Make a payment transaction:

using Algorand.Unity;

var sender = "<your sender address>";
var receiver = "<your receiver address>";
var algod = new AlgodClient("https://node.testnet.algoexplorerapi.io");
var suggestedTxnParams = await algod.GetSuggestedParams();
var microAlgosToSend = 1_000_000L;
var paymentTxn = Transaction.Payment(sender, suggestedTxnParams, receiver, microAlgosToSend);

Sign the transaction with an account:

var account = Account.GenerateAccount();
var signedTxn = account.SignTxn(paymentTxn);

Sign the transaction with kmd:

var kmd = new KmdClient("<host of kmd>");
var walletToken = await kmd.InitWalletHandleToken("<your wallet id>", "<your wallet password>");
var signedTxn = await kmd.SignTransaction(paymentTxn.Sender, paymentTxn.ToSignatureMessage(), walletToken, "<your kmd wallet password>");

Sign the transaction with WalletConnect:

using Algorand.Unity.WalletConnect;

SavedSession savedSession = [...];
var session = new AlgorandWalletConnectSession(savedSession);
var walletTransaction = WalletTransaction.New(paymentTxn);
var signedTxns = await session.SignTransactions(new[] { walletTransaction });
var signedTxn = signedTxns[0];

Send the signed transaction:

await algod.SendTransaction(signedTxn);

Initiate a WalletConnect session and generate a QR Code:

using Algorand.Unity;
using Algorand.Unity.WalletConnect;
using UnityEngine;

var dappMeta = new ClientMeta
{
    Name = "<name of your dapp>",
    Description = "<description of your dapp>",
    Url = "<url of your dapp>",
    IconUrls = new[]
    {
        "<icon1 of your dapp>", "<icon2 of your dapp>"
    }
};
var session = new AlgorandWalletConnectSession(dappMeta);
var handshake = await session.StartConnection();
Texture2D qrCode = handshake.ToQrCodeTexture();

Installation

Open UPM

The easiest way to install is to use Open UPM as it manages your scopes automatically. You can install Open UPM here. Then use the Open UPM CLI at the root of your Unity project to install.

> cd <your unity project>
> openupm add com.careboo.unity-algorand-sdk

Manually Adding UPM Scopes

If you don't want to use Open UPM, it's straightforward to manually add the UPM registry scopes required for this package. See Unity's official documentation on Scoped Registries.

Unity Asset Store
