Transaction tx;
tx.addTransferInstruction(senderPubkey, receiverPubkey, 1000000); // 0.001 SOL
 
uint8_t blockhash[BLOCKHASH_SIZE];
rpcClient.getLatestBlockhashBytes(blockhash);
tx.setRecentBlockhash(blockhash);
tx.sign(senderPrivateKey, senderPubkey);
 
char txBase64[2048];
TransactionSerializer::encodeTransaction(tx, txBase64, sizeof(txBase64));
String resp = rpcClient.sendTransaction(String(txBase64));
