Getting Started
The Pooled Staking API is currently available with exclusive access.
Public availability will be announced soon. To request access or discuss integration, please contact us.
Staking via the Pooled Staking API enables enterprise partners to offer secure, seamless ETH staking to their users, without 32 ETH minimum. The process consists of the following steps:
- Get the list of available vaults.
- Prepare a deposit transaction.
- Sign and broadcast the transaction.
You can also track the staking rewards, as well as monitor historical balance and APY.
Below, a lifecycle diagram of the process is provided.

1. Get List Vaults
Retrieve the list of vaults available to your integration on the target network by sending a GET request to /api/v1/staking/pool/[network]/staking/vaults.
Example request (for hoodi network):
curl --request GET \
--url https://api-test.p2p.org/api/v1/staking/pool/hoodi/staking/vaults \
--header 'accept: application/json' \
--header 'authorization: Bearer <token>' \
--header 'content-type: application/json' \

"vaultAddress": "0xba447498dc4c169f2b4f427b2c4d532320457e89",
"amount": 0.01
}'delegatorAddress— account address of the user initiating the staking transaction.vaultAddress— Ethereum address of the vault. Mind to specify the correctvaultAddressfor all staking operations.amount— amount of tokens in ETH. The value must be decimal, e.g., 0.01.
