+## Using [TransactionBuilder](./src/types/TransactionBuilder.md)
+
+The TransactionV1Builder is a base class used to create various types of transactions. By extending this class, you can build custom transaction types with specific methods and properties.
+
+#### Example of how to construct a transaction with TransactionBuilder and push it to the network:
+
+```ts
+import {
+  HttpHandler,
+  RpcClient,
+  NativeTransferBuilder,
+  PrivateKey,
+  KeyAlgorithm,
+  PublicKey,
+  Transaction
+} from 'casper-js-sdk';
+
+const rpcHandler = new HttpHandler('http://<Node Address>:7777/rpc');
+const rpcClient = new RpcClient(rpcHandler);
+
+const privateKey = await PrivateKey.generate(KeyAlgorithm.ED25519);
+
+const transactionV1 = new NativeTransferBuilder()
+  .from(sender.publicKey)
+  .target(
+    PublicKey.fromHex(
+      '0202f5a92ab6da536e7b1a351406f3744224bec85d7acbab1497b65de48a1a707b64'
+    )
+  )
+  .amount('25000000000') // Amount in motes
+  .id(Date.now())
+  .chainName('casper-net-1')
+  .payment(100_000_000)
+  .build();
+
+await transactionV1.sign(privateKey);
+
+const tx = Transaction.fromTransactionV1(transactionV1);

+try {
+  const result = await rpcClient.putTransaction(tx);
+  console.log(`Transaction Hash: ${result.transactionHash}`);
