Solana - создана ассоциированная учетная запись токена ⇐ C#

[Anonymous]

У меня есть кошелек платформы с некоторым Sol в нем. Я создал токен SPL и изгонял.private async Task CreateAssociatedTokenAccount(Wallet wallet, string vtcMintAddress)
{
try
{
// Initialize the RPC client to interact with the blockchain
IRpcClient rpcClient = ClientFactory.GetClient(Cluster.MainNet); // Use Mainnet

var userPublicKey = wallet.Account.PublicKey;
var mintAddress = new PublicKey(vtcMintAddress); // VTC Mint Address

// Derive the associated token account address using the associated token account program
var associatedTokenAddress = AssociatedTokenAccountProgram.DeriveAssociatedTokenAccount(
userPublicKey, mintAddress);

// Check if the associated token account already exists
var accountInfo = await rpcClient.GetAccountInfoAsync(associatedTokenAddress);
if (accountInfo.Result?.Value != null)
{
Console.WriteLine($"Associated token account already exists for {userPublicKey}");
return;
}

// Get the recent blockhash from the Solana network
var blockHashResult = await rpcClient.GetLatestBlockHashAsync();

// Extract the blockhash from the result
string blockhash = blockHashResult.Result.Value.Blockhash;

// Use the pre-defined platform wallet address (the one you already have as a constant)
var platformWalletAddress = new PublicKey(Constants.PlatformWalletPubKey); // Use your platform wallet's public key

// Optionally, retrieve the private key for the platform wallet if needed (if you need to sign transactions)
// You can securely store or access the private key for this wallet.
var platformWallet = new Wallet(Constants.PlatformWalletPrivateKey);

// Create the associated token account transaction
var tx = new TransactionBuilder()
.SetRecentBlockHash(blockhash) // Use the blockhash string directly
.SetFeePayer(platformWallet.Account) // Platform wallet is the fee payer
.AddInstruction(AssociatedTokenAccountProgram.CreateAssociatedTokenAccount(
platformWallet.Account.PublicKey, // payer (platform wallet)
userPublicKey, // owner of the new token account
mintAddress)); // mint of the token (VTC)

byte[] txBytes = tx.Build(new List { platformWallet.Account });

// Send the transaction to the network
var result = await rpcClient.SendTransactionAsync(Convert.ToBase64String(txBytes));
if (result.WasSuccessful)
{
Console.WriteLine($"Successfully created associated token account: {associatedTokenAddress}");
}
else
{
Console.WriteLine($"Failed to create associated token account: {result.Reason}");
}
}
catch (Exception ex)
{
Console.WriteLine($"Error creating associated token account: {ex.Message}");
}
}
