# Quickstart: send through a provider route

> Copy a Bifrost route URL, submit a signed transaction to LunarLander, and confirm the returned signature through ThorEdge RPC.

In about five minutes you will send one signed transaction through a Bifrost route and see the provider's signature come back.

## Before you start

You need:

* An access with **Private TX** enabled for a location
* A signed, base64-encoded Solana transaction that pays the provider's minimum tip (LunarLander: 1,000,000 lamports to a [LunarLander tip address](/api-reference/bifrost/lunarlander#tip-addresses))
* The complete ThorEdge RPC URL of the same access, to confirm the signature

<Steps>
  <Step title="Generate a Private TX key">
    Open **Endpoints → Private TX**, select the access and a location, and generate the key if the access has none.
  </Step>

  <Step title="Copy the LunarLander Submit URL">
    Choose **LunarLander → Submit** and copy the complete route URL. It already contains the key.

    ```bash theme={null}
    export BIFROST_ROUTE_URL='<LUNARLANDER_SUBMIT_URL_COPIED_FROM_DASHBOARD>'
    ```
  </Step>

  <Step title="Send the transaction">
    ```bash theme={null}
    curl --fail-with-body --silent --show-error "$BIFROST_ROUTE_URL" \
      --header 'content-type: application/json' \
      --data '{
        "jsonrpc": "2.0",
        "id": 1,
        "method": "sendTransaction",
        "params": ["<BASE64_SIGNED_TRANSACTION>", { "encoding": "base64" }]
      }'
    ```

    A successful submit returns the signature:

    ```json theme={null}
    { "jsonrpc": "2.0", "id": 1, "result": "<TRANSACTION_SIGNATURE>" }
    ```
  </Step>

  <Step title="Confirm it landed">
    ```bash theme={null}
    curl --fail-with-body "$THORNODE_RPC_URL" \
      --header 'content-type: application/json' \
      --data '{"jsonrpc":"2.0","id":1,"method":"getSignatureStatuses","params":[["<TRANSACTION_SIGNATURE>"],{"searchTransactionHistory":true}]}'
    ```

    The transaction landed when `result.value[0]` is not `null` and reports your commitment.
  </Step>
</Steps>

A `401` means the URL is stale or the key is not in the path; recopy it. A `400` with `guardrail reject` names the check that failed, most often `tip_too_low`.
