The Unity SDK supports SUI blockchain operations including transfers, message signing, and raw transaction signing.

​
Sign and send SUI transfer

// Sign only (does not broadcast)
string signature = await DynamicSDK.Instance.Networks.Sui.SignTransferTransaction(
    wallet.Id, "0xRecipientAddress", "0.1");

// Sign and broadcast
string digest = await DynamicSDK.Instance.Networks.Sui.SignAndSendTransferTransaction(
    wallet.Id, "0xRecipientAddress", "0.1");

Debug.Log($"Transaction digest: {digest}");

​
Sign message

string signature = await DynamicSDK.Instance.Networks.Sui.SignMessage(
    wallet.Id, "Hello from SUI");

​
Sign raw transaction

Sign a base64-encoded transaction: 
string signature = await DynamicSDK.Instance.Networks.Sui.SignTransaction(
    wallet.Id, base64TransactionBytes);

​
Send raw transaction

Send a base64-encoded transaction: 
string digest = await DynamicSDK.Instance.Networks.Sui.SendTransaction(
    wallet.Id, base64TransactionBytes);
