Connect Hyperliquid

Connecting gives Prow a trading key for your Hyperliquid account. The key lives on this device. It can place orders. It can never withdraw.

You need a Hyperliquid account first. Hyperliquid opens one with your first deposit (min 5 USDC). No account? See Deposit funds.

Connect step by step

1. Open Connect Hyperliquid

   New users land on Where do you trade? after sign-in. Later, open Connect a venue on Portfolio (the link under By venue, or step 1 of Get started) and tap Connect next to Hyperliquid. Settings > Venues has the same Connect button.

2. Pick how to connect

   Signed in with a wallet? Its card shows what Hyperliquid has for it: tap Continue with this wallet, or Use a different wallet. Otherwise Connect wallet is the usual choice. Use Prow wallet shows up if you have a Prow wallet. Use an API key instead is for keys you made on Hyperliquid.

3. Pick the wallet that holds your account

   Prow reads your Hyperliquid account and shows Found on Hyperliquid with your balance. If it says No Hyperliquid account, tap Deposit USDC: your first deposit opens the account, and this step goes on by itself when it lands.

4. Sign 1: approve the trading key

   Tap Approve in your wallet, for example Approve in MetaMask. Your wallet asks you to sign approveAgent. Free. No funds move.

5. Sign 2 (optional): approve the Prow fee

   Tap Approve in your wallet again, or tap Later.

6. Done

   You see Hyperliquid connected. Tap Done, or Deposit USDC to add funds.

Sign 1: the trading key

Your wallet signs an approval for a new key made on this device. Before you sign, Prow shows what the key can and cannot do:

• Can: place, modify and cancel orders.
• Can: change leverage and margin.
• Cannot: withdraw or transfer funds. Never.
• Cannot: approve other apps. Never.

Open What you're signing to see Agent name, Agent address and Valid until. Check that the agent address in your wallet matches. The name looks like "Prow iPhone k3f", so you can tell your devices apart on Hyperliquid.

The key is valid for up to 180 days. From 14 days before it expires, Portfolio's Needs attention shows Renew key. You can also renew in Settings > Venues: Renew trading key on the card, or Renew on its Details page.

Sign 2: the Prow fee

This signature lets Prow add its fee to trades you place through Prow. It is the Hyperliquid "builder fee".

• You approve a maximum of 0.025% per trade. Hyperliquid caps builder fees at 0.1% on perps.
• Prow charges 0% until Dec 31, 2026. From Jan 1, 2027 it charges 0.025%.
• The approval cannot move or withdraw funds.

You can skip it with Later. You can still trade during the free period. Closing and reducing positions always work, even without the approval. Approve it any time in Settings > Venues, on the account's card. See Fees.

The summary explains each row:

Under the summary, Prow offers Save to passkey. This backs up the key so your other devices can use it without a wallet signature. See Back up keys with a passkey.

Key limit: three per account

Hyperliquid allows at most 3 named trading keys per account. If you connect a fourth device, Prow shows Replace a trading key. Pick one and tap Replace.
