The EigenLayer restaking flow includes the following steps:

Create EigenPod address: construct a serialized transaction to generate an EigenPod address, which your validator can use as a withdrawal address.
Create Staking Request: set up nodes for staking using P2P infrastructure.
Check Request Status: check the status of the node set-up operation.
Prepare Staking Transaction: construct a serialized transaction to deposit the stake amount with a smart contract.
Verify Withdrawal Credentials: construct a serialized transaction to verify the validator withdrawal credentials on-chain.
Prepare Delegate Restake Transaction: construct a serialized transaction to delegate the restake amount to the EigenLayer node operator.

Get an authentication token to start using Restaking API.

Request examples are provided using cURL.

1. Create EigenPod Address

Retrieve a serialized transaction to generate an EigenPod address by sending a POST request to /api/v1/eth/staking/eigenlayer/tx/create-pod. Use https://api-test-holesky.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/eigenlayer/tx/create-pod \
     --header 'accept: application/json' \
     --header 'authorization: Bearer <token>'
     --header 'content-type: application/json'

Example response:

serializeTx — serialized unsigned transaction.
to — recipient address for this transaction.
gasLimit — maximum gas 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 to sign and send the signed transaction to the Ethereum network.

By broadcasting this transaction, you are generating an EigenPod address. The Ethereum address used to sign this transaction will become the eigenPodOwnerAddress.

2. Create Stake 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 with the RESTAKING type to /api/v1/eth/staking/direct/nodes-request/create.

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' \

       "location": "any",
       "relaysSet": null
    }
}
'
```

4. Prepare Staking Transaction

There are two ways to prepare a staking transaction using the Restaking API:

Interact directly with the Ethereum Deposit Smart Contract.
Utilize the P2P smart contract.

Ethereum Deposit Smart Contract

📘
This option may be preferrable if you have a lot of engineering resources available and do not want your infrastructure to have an extra dependency.

Retrieve all the required data from the previous step within the depositData object and prepare the staking transaction.
Construct a signature and send the deposit amount to the Ethereum deposit smart contract. Check an example of how to sign and send a transaction to the Ethereum network.

P2P Smart Contract

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

Example request:

curl --request POST \
     --url https://api.p2p.org/api/v1/eth/staking/direct/tx/deposit \
     --header 'accept: application/json' \
     --header 'authorization: Bearer <token>' \

Use serializeTx 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.

5. Verify Withdrawal Credentials

📘
The validator activation can take up from 16 to 24 hours. To check whether the validator is active, retrieve its status by sending a POST request to /api/v1/eth/staking/direct/validator/status.
Before proceeding further, wait until the validator gets the active_ongoing status and starts performing the validator duties.

Initiate verifying the withdrawal credentials to the EigenPod address by sending a POST request to /api/v1/eth/staking/eigenlayer/tx/verify-withdrawal-credentials. These credentials will be used to verify that the validator will withdraw its principal to this EigenPod in case it exits the Beacon chain.
Example request:

curl --request POST \
     --url https://api.p2p.org/api/v1/eth/staking/eigenlayer/tx/verify-withdrawal-credentials \
     --header 'accept: application/json' \
     --header 'authorization: Bearer <token>' \
     --header 'content-type: application/json' \
     --data '
{
    "eigenPodOwnerAddress": "0x27AABeE07E0dbC8b0de20f42b1a1980871314Ef5",
    "pubkey": "0xffC08FcD7cFeF5c70fB2b0e1f2A8EaA690AaE2bDFfa5dBEc4dEef31DcC0B19eB1f9Cebe3E2fe9eefBD9a1BDF6FD89b39"
}
'

eigenPodOwnerAddress — owner of the EigenPod address.
pubkey — validator public keys.

Use serializeTx to sign and send the signed transaction to the Ethereum network.

By broadcasting this transaction, you are verifying the validator withdrawal credentials on-chain. You can now delegate your restake amount to an EigenLayer node operator.

🚧
Note that the transaction signing is time sensitive
The transaction has to be signed in 8192 slots (approximately 27 hours).
If the time has expired and you have not signed the transaction yet, contact us for support.
