# Sign and Broadcast Transaction

> To complete any staking or withdrawal operation on Solana, sign the unsigned transaction provided by the Staking API and broadcast it to the network.

## 1. Prepare the transaction

Retrieve an unsigned transaction in Base64 encrypted format from the relevant API endpoint, e.g., `/staking/stake`, `/staking/deactivate` or `/staking/withdraw`.

## 2. Sign the transaction

Use the [P2P Signer SDK](/docs/signer-sdk-overview) to sign the unsigned data following protocol specific configuration.

## 3. Send the transaction

Send the signed transaction to the Solana network by making a POST request to [/api/v1/solana/\{network}/tx/send](/reference/solana-staking-send).

Example request (for `testnet` network):

<CodeGroup>
  ```bash curl theme={null}
  curl --request POST \
       --url https://api-test.p2p.org/api/v1/solana/testnet/tx/send \
       --header 'accept: application/json' \
       --header 'authorization: Bearer <token>' \
       --header 'content-type: application/json' \
       --data '
       {
         "signedTransaction": "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"
