# makeCsprTransferTransaction

Creates a `Transaction` for a native CSPR transfer. Uses `NativeTransferBuilder` for Casper 2.0 nodes and wraps a legacy `Deploy` for 1.x nodes.

## Import

```ts
import { makeCsprTransferTransaction } from 'casper-js-sdk';
```

## Usage

```ts
const status = await rpcClient.getStatus();

const transaction = makeCsprTransferTransaction({
  senderPublicKeyHex: privateKey.publicKey.toHex(),
  recipientPublicKeyHex: recipientPublicKey.toHex(),
  transferAmount: '2500000000',   // 2.5 CSPR in motes
  paymentAmount: '100000000',     // 0.1 CSPR gas
  chainName: 'casper',
  memo: String(Date.now()),
  casperNetworkApiVersion: status.apiVersion,
});

transaction.sign(privateKey);
const result = await rpcClient.putTransaction(transaction);
console.log('Hash:', result.transactionHash);
```

## Parameters

| Parameter | Type | Required | Default |
|---|---|---|---|
| `senderPublicKeyHex` | `string` | yes | - |
| `recipientPublicKeyHex` | `string` | yes | - |
| `transferAmount` | `string` | yes | - |
| `casperNetworkApiVersion` | `string` | yes | - |
| `paymentAmount` | `string` | no | `'100000000'` |
| `chainName` | `string` | no | `'casper'` |
| `memo` | `string` | no | - |
| `ttl` | `number` | no | `1800000` |
| `timestamp` | `string` | no | now |
| `gasPrice` | `number` | no | `1` |

### casperNetworkApiVersion

Pass the API version string from `rpcClient.getStatus()`. If it starts with `'2'`, a `TransactionV1` is built. Otherwise a legacy `Deploy` is wrapped.

## Return Value

`Transaction`
