# perpDeploy | Hyperliquid exchange
> Deploys a new perpetual contract on a Hyperliquid perp DEX. Chainstack supports perpDeploy on Hyperliquid exchange JSON-RPC nodes.
You can only use this endpoint on the official Hyperliquid public API. It is not available through Chainstack, as the open-source node implementation does not support it yet. See [Hyperliquid methods](/docs/hyperliquid-methods) for the full availability breakdown.
This endpoint requires signature authentication. See our comprehensive [Authentication via Signatures guide](/docs/hyperliquid-authentication-guide) for implementation details.
Deploys a new perpetual contract on a Hyperliquid perp DEX.
## Parameters
### Required parameters
* `action` (object, required) — The action object containing:
* `type` (string) — Must be `"perpDeploy"`
* `config` (object) — Perpetual deployment configuration
* `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 processed
* `response` — Contains action result data
## Example request
```shell cURL theme={"system"}
curl -X POST https://api.hyperliquid.xyz/exchange \
-H "Content-Type: application/json" \
-d '{
"action": {"type": "perpDeploy"},
"nonce": 1234567890123,
"signature": {...}
}'
```
```python Python (hyperliquid-python-sdk) theme={"system"}
from hyperliquid.exchange import Exchange
from hyperliquid.utils import constants
from eth_account import Account
# Signing is required: load the deployer wallet from its private key.
wallet = Account.from_key("0x...")
exchange = Exchange(wallet, constants.MAINNET_API_URL)
# perpDeploy / registerAsset: register a new perp asset on a builder-deployed perp DEX.
result = exchange.perp_deploy_register_asset(
dex="test",
max_gas=1000000,
coin="USDC",
sz_decimals=8,
oracle_px="1",
margin_table_id=1,
only_isolated=False,
schema=None,
)
print(result)
```
```typescript TypeScript (@nktkas/hyperliquid) theme={"system"}
import * as hl from "@nktkas/hyperliquid";
import { privateKeyToAccount } from "viem/accounts";
// Signing is required: load the deployer wallet from its private key.
const wallet = privateKeyToAccount("0x..."); // viem or ethers
const transport = new hl.HttpTransport(); // public mainnet API
const client = new hl.ExchangeClient({ transport, wallet });
// perpDeploy / registerAsset: register a new perp asset on a builder-deployed perp DEX.
const result = await client.perpDeploy({
registerAsset: {
maxGas: 1000000,
assetRequest: {
coin: "USDC",
szDecimals: 8,
oraclePx: "1",
marginTableId: 1,
onlyIsolated: false,
},
dex: "test",
schema: null,
},
});
console.log(result);
```
## Use case
* **Perp deploy** — Deploys a new perpetual contract on a Hyperliquid perp DEX.
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.
