Getting Started

To start staking on the Ethereum network using the Staking API:

Set up nodes for staking using P2P infrastructure.
Check the status of the node set-up operation.
Construct a serialized transaction to deposit the stake amount with a smart contract.

Get an authentication token to start using Staking API. Request examples are provided using cURL.

Please noteOn May 7, 2025, the major Ethereum network upgrade was carried out that brought many benefits for clients who use ETH or SSV validators. P2P.ORG recommends upgrading to the 0x02 withdrawal credentials to enhance your functionality. It can be done in two ways:

By consolidating multiple existing validators into a single one
By creating a new 0x02-enabled validator via simplified 3.1 integrators with smart contract flow allowlists

For more details, see Pectra Upgrade overview.However, upgrading to the new address format is not necessary, all existing endpoints remain supported. You can follow the 0x01 creation flow below, if you need fine-grained control over validator count, effective balance per validator, or you intend to manually broadcast deposit transactions.

Create setting-up node request

Prepareid that is an arbitrary UUID. Generate it in one of the following ways:
- Online UUID Generator
- uuid npm package
Set up staking nodes through the P2P infrastructure by sending a POST request to /api/v1/eth/staking/direct/nodes-request/create. Use https://api-test.p2p.org for testing or https://api.p2p.org for production. Example request:
curl --request POST \ --url https://api.p2p.org/api/v1/eth/staking/direct/nodes-request/create \ --header 'accept: application/json' \ --header 'authorization: Bearer <token>' \ --header 'content-type: application/json' \ --data ' { "id": "3611b95c-e1b3-40c0-9086-3de0a4379943", "type": "REGULAR", "validatorsCount": 2, "amountPerValidator": "32000000000", "withdrawalCredentialsType": "0x01", "withdrawalAddress": "0x39D02C253dA1d9F85ddbEB3B6Dc30bc1EcBbFA17", "eigenPodOwnerAddress": "", "controllerAddress": "0x39D02C253dA1d9F85ddbEB3B6Dc30bc1EcBbFA17", "feeRecipientAddress": "0x53da3c92fCCEb0CFE1764f65DDfF1564A2b15585", "nodesOptions": { "location": "any", "relaysSet": "" } }'
- id — arbitrary UUID. You can later use that UUID to check the status of the set-up operation.
- type — staking operation type:
  - REGULAR— default value for native staking transactions. Set the REGULAR operation type for this flow.
  - RESTAKING— value that is used to initiate a restaking operation with the EigenPod address.
  - MANAGED_SSV— value that is used to initiate a managed SSV cluster.
- validatorsCount — number of validators. One validator is equal to 32 ETH.
- amountPerValidator — amount of tokens to stake in Gwei per validator. Note that if the amount is more than 32 ETH (1 ETH = 10⁹ Gwei), the withdrawalCredentialsType parameter defaults to 0x02.
- withdrawalCredentialsType — withdrawal credentials preferred format: 0x01 or 0x02.
- withdrawalAddress — withdrawal address for the validators.
- eigenPodOwnerAddress — owner of the EigenPod address. Used in the restaking flow.
- feeRecipientAddress — fee recipient address.
- controllerAddress — for the validators.
- nodesOptions:
  - location — node location. Currently, only any is supported.
  - relaysSet — Miner Extractable Value () relay selection.
Example response:
{ "error": null, "result": true }

Check request status

After setting up the node, check the status of the node set-up operation by sending a GET request to /api/v1/eth/staking/direct/nodes-request/status/{id} . You must poll this until status is ready.Example request:

curl --request GET \
     --url https://api.p2p.org/api/v1/eth/staking/direct/nodes-request/status/3611b95c-e1b3-40c0-9086-3de0a4379943 \
     --header 'accept: application/json' \
     --header 'authorization: Bearer <token>'

id — UUID that was specified in the node set-up request.

Prepare staking transaction

After setting up the nodes and successfully generating the depositData, retrieve it and proceed with make the deposit.There are two flows to make a deposit:

Workflow	Best For	Logic
Simplified Smart Contract	Most Users	Uses P2P proxy contract to handle registration and deposit in one flow.
Direct Interaction	Power Users	Manually interacting with the Ethereum Deposit Contract for fine-grained control.

P2P Proxy deposit

Create a serialized transaction for depositing the stake amount and send it as a POST request to /api/v1/eth/staking/direct/tx/deposit.

curl --request POST \

serializeTx — serialized unsigned transaction.
to — recipient address for this transaction.
gasLimit — maximum limit for this block.
data — transaction data.
value — amount this transaction is sending in Wei.
chainId — chain ID this transaction is authorized on, as specified by EIP-155.
type — EIP-2718 type of this transaction envelope.
maxFeePerGas — maximum price per unit of gas this transaction will pay for the combined EIP-1559 block’s base fee and this transaction’s priority fee in Wei.
maxPriorityFeePerGas — price per unit of gas in Wei, which is added to the EIP-1559 block’s base fee. This added fee is used to incentivize miners to prioritize this transaction.

Use serializeTx from the previous step to sign and send the signed transaction to the Ethereum network.By broadcasting this transaction, you are depositing the required stake amount in the Ethereum deposit smart contract by using the P2P smart contract as a proxy.

Ethereum direct deposit

Use this if you prefer to interact with the official Ethereum contract without a proxy.

Take the pubkey, signature, and depositDataRoot from the deposit-data response.
Go to the Official Ethereum Deposit Contract
Manually execute the deposit function with your 32 ETH and the provided data.

After your deposit is successful, your validator will enter the activation queue and soon start performing the validator tasks.
