Stake ETH with Kiln

Prerequisites

Requirements :

• Ledger Enteprise with Smart contract Interaction support (to activate this feature on your workspace, please reach out to your Technical Account Manager)
• LAM setup
• Admin access to the Ledger Enteprise Application

How to start :

1. Create your API users
2. Create an Ethereum Account (that owns at least 32 ETH), with a dedicated Smart Contract goverance rule , as Ethereum Staking relies on interacting with Kiln's staking contract; therefore, staking operations on Ethereum are managed by the Smart Contract rule (as opposed to the Staking rule that you can find for accounts on other protocols, such as Tezos or Solana)
3. Add the relevant API users to the ETH Staking Smart Contract governance rule, based on your business workflows.

Environment variables

LAM_URL = "https://eth-staking.minivault.ledger-sbx.com/lam"
API_USER_NAME = "bluestar" #The username of the API Operator you set as Creator in the Smart Contract rule of your MATIC Staking account
HEADER = {'X-Ledger-API-User': API_USER_NAME}

Create your programmatic staking operation request

You can initiate your ETH staking request programmatically by calling the POST/transactions endpoint. Below is an example of a request body to create a request to stake 32 tETH (on Goerli) with Kiln, using the encoded payload.

payload = {
  "account_name": "ETH Staking",
  "amount": "32",
  "coin_fields": {
    "contract_interaction": {
        "contract_data": "0xd0e30db0"
        }
    },
  "max_fees": "1000000000000000000",
  "note": {
    "content": "Stake ETH with Kiln",
    "title": "ETH Staking"
    },
  "recipient": "0x9c1D4220cA82115167A5da4c00c062C78Fd3D3F8", 
  "speed": "FAST"
}

r = request.post(LAM_URL + "/transactions", json=payload, headers=HEADER)
r.json

Once the transaction is fully approved, it will be signed and broadcast. You will have succesfully staked your ETH, and will start earning rewards. You can monitor your staking positions by heading to Kiln's DApp in the DApps section of your Ledger Enterprise platform, or by calling the GET /accounts endpoint. To monitor all your individual staking positions via API, you can also leverage our GET /ethereum/accounts/{account_id}/stakes endpoint.
