Parameters
Required parameters
action(object, required) — The action object containing:type(string) — Must be"validatorL1Stream"payload(object) — L1 stream payload
nonce(number, required) — Current timestamp in milliseconds (must be recent)signature(object, required) — EIP-712 signature of the action
Optional parameters
vaultAddress(string, optional) — Address when trading on behalf of a vault or subaccount
Returns
Returns an object with the action status:status—"ok"if request processedresponse— Contains action result data
Example request
curl -X POST https://api.hyperliquid.xyz/exchange \
-H "Content-Type: application/json" \
-d '{
"action": {"type": "validatorL1Stream"},
"nonce": 1234567890123,
"signature": {...}
}'
# hyperliquid-python-sdk has no typed validatorL1Stream wrapper, so build and
# sign the L1 action with the same primitives its typed methods use internally.
import eth_account
from hyperliquid.exchange import Exchange
from hyperliquid.utils import constants
from hyperliquid.utils.signing import sign_l1_action, get_timestamp_ms
wallet = eth_account.Account.from_key("0x...") # your validator key
exchange = Exchange(wallet, constants.MAINNET_API_URL)
action = {"type": "validatorL1Stream", "riskFreeRate": "0.05"}

signature = sign_l1_action(

)
result = exchange._post_action(action, signature, nonce)

import { ExchangeClient, HttpTransport } from "@nktkas/hyperliquid";
import { privateKeyToAccount } from "viem/accounts";
const wallet = privateKeyToAccount("0x..."); // your validator key
const transport = new HttpTransport(); // public mainnet
const exchange = new ExchangeClient({ transport, wallet });
const result = await exchange.validatorL1Stream({

Use case
- Validator L1 stream — Submits a validator L1 stream action for processing consensus-layer events.
Always ensure your system clock is synchronized. Nonce must be within a reasonable time window of the current server time or the request will be rejected.
