Example request

cURL

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

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

# Agent wallet approved to act on behalf of the user
agent = Account.from_key("AGENT_PRIVATE_KEY")

exchange = Exchange(agent, constants.MAINNET_API_URL)

# abstraction is one of "u" (unifiedAccount), "p" (portfolioMargin), "i" (disabled)
result = exchange.agent_set_abstraction("u")
print(result)

import { ExchangeClient, HttpTransport } from "@nktkas/hyperliquid";
import { privateKeyToAccount } from "viem/accounts";

// Agent wallet approved to act on behalf of the user
const wallet = privateKeyToAccount("0x...");

const transport = new HttpTransport(); // default public Hyperliquid API
const exchange = new ExchangeClient({ transport, wallet });

// abstraction is one of "u" (unifiedAccount), "p" (portfolioMargin), "i" (disabled)
