Parameters

​
Required parameters

  • action (object, required) — The action object containing:
    • type (string) — Must be "agentEnableDexAbstraction"
    • dexAbstraction (object) — DEX abstraction 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

​
Example request

curl -X POST https://api.hyperliquid.xyz/exchange \
  -H "Content-Type: application/json" \
  -d '{
    "action": {"type": "agentEnableDexAbstraction"},
    "nonce": 1234567890123,
    "signature": {...}
  }'

from eth_account import Account
from hyperliquid.exchange import Exchange
from hyperliquid.utils import constants

# The wallet must be the approved agent wallet for the user.
wallet = Account.from_key("YOUR_AGENT_PRIVATE_KEY")
exchange = Exchange(wallet, constants.MAINNET_API_URL)

# Signs the action (EIP-712) and posts it. Deprecated in favor of agent_set_abstraction.
result = exchange.agent_enable_dex_abstraction()
print(result)

import * as hl from "@nktkas/hyperliquid";
import { privateKeyToAccount } from "viem/accounts";

// The wallet must be the approved agent wallet for the user.
const wallet = privateKeyToAccount("YOUR_AGENT_PRIVATE_KEY"); // viem or ethers
const transport = new hl.HttpTransport(); // public mainnet API
const client = new hl.ExchangeClient({ transport, wallet });

// Signs the action (EIP-712) and posts it. Deprecated in favor of agentSetAbstraction.
const result = await client.agentEnableDexAbstraction();
console.log(result);
