# SendTransaction

## sendTransaction RPC Method

Submits a signed transaction to the cluster for processing.

#### Method Behavior

* Relays the transaction to the node exactly as created by clients
* Immediate success means the RPC service received the transaction
* Success does NOT guarantee transaction processing or confirmation
* Transaction could be rejected if `recent_blockhash` expires

#### Preflight Checks

Before submission, the following checks are performed:

1. Verify transaction signatures
2. Simulate transaction against bank slot specified by preflight commitment

    #### Parameters

    `string` **required**\
    Fully-signed Transaction

    * Encoded as a string

    `object` **optional**\
    Configuration object with the following fields:

    **encoding** `string`

    * Default: `base58`
    * Encoding for transaction data

    **Allowed Encoding Values:**

    * `base58` (*slow*, **DEPRECATED**)
    * `base64`

    **skipPreflight** `bool`

    * Default: `false`
    * When `true`, skips preflight transaction checks

    **preflightCommitment** `string`

    * Default: `finalized`
    * Commitment level for preflight checks

    **maxRetries** `usize`

    * Maximum RPC node retries for sending transaction
    * If not provided, retries until finalized or blockhash expires

    **minContextSlot** `number`

    * Minimum slot for performing preflight checks

    #### Code Sample

    ```bash theme={"system"}
    curl https://rpc.testnet.soo.network/rpc \
    -X POST \
    -H "Content-Type: application/json" \
    -d '{
      "jsonrpc": "2.0",
      "id": 1,
      "method": "sendTransaction",
      "params": [
        "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=",
        {
          "skipPreflight": false,
          "preflightCommitment": "finalized",
          "encoding": "base64",
          "maxRetries": 3
        }
      ]
    }'
    ```

    #### Response

    ```json theme={"system"}
    {
      "jsonrpc": "2.0",
      "result": "5ThJTCxpdn54bk3gBAWKZS4K9ogHEX56WooYbXQDnm3Q",
      "id": 1
    }
    ```
  </div>
</div>

#### Result Details

* `<string>` - Transaction Signature
  * First signature embedded in the transaction
  * Base-58 encoded string
  * Used as the transaction identifier

#### Important Notes

* Recommended to use `getSignatureStatuses` to confirm transaction processing
* Specify consistent commitment levels to avoid unexpected behavior
* Transaction signatures can be extracted before submission
