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 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.

Example request (for testnet network):

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": "AQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAABAAcJjkQt4XcX43Vk8FZ7QbUVXSF5oo9jt7x2Dm0E9ut/y+jagnMHpK8BDHt0PpssHwXGD2fBxS6MWBoxptD2u9TvrgAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA1NjSeWM5+GSJdoQd43Al9SVVXC9FfWGwbe7icpomwAUGodgXkTdUKpg0N73+KnqyVX9TXIp4citopJ3AAAAAAAah2BelAgULaAeR5s5tuI4eW3FQ9h/GeQpOtNEAAAAABqfVFxjHdMkoVmOYaR1etoteuKObS21cc1VbIQAAAAAGp9UXGSxcUSGMyUw9SvF/WNruCJuh/UTj29mKAAAAAAan1RcZNYTQ/u2bs0MdEyBr5UQoG1e4VmzFN1/0AAAAijW940iwWddz25ZC37fI0ue5fa+eTbC2ynBM3b0t4pcDAgMAAQBgAwAAAI5ELeF3F+N1ZPBWe0G1FV0heaKPY7e8dg5tBPbrf8voBAAAAAAAAABzZWVkgJaYAAAAAADIAAAAAAAAAAah2BeRN1QqmDQ3vf4qerJVf1NcinhyK2ikncAAAAAABAIBB3QAAAAAjkQt4XcX43Vk8FZ7QbUVXSF5oo9jt7x2Dm0E9ut/y+iORC3hdxfjdWTwVntBtRVdIXmij2O3vHYObQT263/L6AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAQGAQMGCAUABAIAAAA="

signedTransaction — signed transaction in Base64 encrypted format.

Example response:

{
  "result": {
    "transactionId": "0x0628743b05ffb4c9d5ea2144b359af38910f0ae439a685f57d85b50b9481ba3f",
    "slot": 17168395,
    "signerAccounts": [
      "C83GxcNFTC2tK22rLCCrLKYRkckbNVGsjethN5iswgfC"
    ],
    "createdAt": "2023-08-15T15:07:54.795Z"
  }
}

transactionId — block hash in which the transaction was included.
slot — period of time during which each leader collects transactions and creates a block in the Solana network.
signerAccounts — account addresses that signed the transaction.
createdAt — timestamp of the transaction in the ISO 8601 format.
