Sign transaction with Wallet class

[MoonNone]

How do you sign a transaction using Wallet class?
I tried to replicate WalletBase code but do not succeed in that :

public static async Task<RequestResult> SignAndSendTransaction(
Transaction transaction, bool skipPreflight = false, Commitment commitment = Commitment.Confirmed)
{
transaction.Sign(m_walletAccount);
transaction.Signatures = DeduplicateTransactionSignatures(transaction.Signatures, allowEmptySignatures: true);
var txSign = await m_walletAccount.Sign(transaction);
txSign.Signatures = DeduplicateTransactionSignatures(tx.Signatures);
return await m_clientRPC.SendTransactionAsync(Convert.ToBase64String(txSign.Serialize()), skipPreflight: skipPreflight, preFlightCommitment: commitment);
}

I wanted to try using phantom at first, but it does not work with Unity except in build mode.
Besides I don't need a "phantom" wallet, I just want to interact with a solana wallet.
All I want is to make a swap, and that's such a nightmare to make that work, I wonder why there isn't a swap function (with tokensell/buy, amount slippage, fee and wallet as parameters) in the SDK which does all the dirty work of getquote/swap/sign/confirm.

You can use any implementation of WalletBase, some such as InGameWallet and Web3Auth work also in editor, have a look here: https://solana.unity-sdk.gg/docs/configuration

The way is suppose to work is trough the Web3 handler, once you login, Web3.Wallet will contains the current wallet used at login. Using Web3.Wallet.SignAndSend will allow to sign and send transaction cross wallets and cross platforms.

Related to the swap, I suggest to refer to the documentation: https://solana.unity-sdk.gg/docs/jupiter
which showcase the script used in the deployed demo: https://magicblock-labs.github.io/Solana.Unity-SDK/ (you can try the swap there). The implementation follows the Jupiter API v6 (https://station.jup.ag/docs/apis/swap-api)

@MoonNone you can follow the setup tutorial: https://solana.unity-sdk.gg/docs/installation

Afterwards, you can build a transaction and sign it with the cross platform method: Web3.Wallet.SignAndSendTransaction(tx);, which works with Phantom or any other method used at logic. It will be auto-detected and works cross-platform.

Here is an example for creating and signing a minting transaction: https://solana.unity-sdk.gg/docs/mint-an-nft

it uses WalletBase, I'm using Wallet.
Is there no way to make a transaction with Wallet?

[GabrielePicco]

Wallet is an implementation of WalletBase. Using the Web3.Wallet is the suggested way, as it's handle the cross platform, cross wallet signatures.
