Turn on one-tap trading

The two wallet signatures that turn on trading on Hyperliquid through Hypertake, what each allows, how long it lasts and how to turn it off

One-tap trading lets Hypertake send your orders to Hyperliquid without opening your wallet for each trade. You turn it on once per browser: on mainnet your wallet signs two messages, first approving Hypertake's builder fee (a maximum of 1%), then approving a trading key made in your browser, valid for 179 days. Neither signature moves money or costs gas.

#What happens when you turn it on

#Signature 1: Hypertake's fee

Hyperliquid lets an interface add a builder fee to the orders it sends, but only up to a maximum each user approves with their main wallet (Builder codes). This signature approves a maximum of 1% for Hypertake's builder address. What Hypertake actually charges is lower on most orders:

The approval is required to trade on Hypertake. If you decline it, nothing else is asked and trading stays off: "Trading on Hypertake needs its fee approved: nothing was changed." It's approved once per account, so a second browser or your phone asks only for its own trading key.

#Signature 2: the trading key

Hypertake makes a new private key inside your browser, then asks your wallet to approve it as an agent of your account (Hyperliquid's term; also called an API wallet). Once approved, Hypertake signs your orders with it, which is why no wallet window opens when you press Buy.

Where it's kept

In this browser's storage (IndexedDB), encrypted with a key the browser won't let anyone export. It is never sent to Hypertake's server. Code running on hypertake.net in this browser can use it; that's how orders get signed. See The trading key.

Its name

Each browser's key has its own name on Hyperliquid, such as Hypertake w 7f3a (desktop) or Hypertake p 2c91 (phone), so turning one device's key on or off never affects another's.

Clearing site data

Deletes the key. The next trade asks you to approve a new one.

#Turn it on

#On desktop

1. 1

   Find the button

   On any outcome market, the trade ticket shows a Turn on one-tap trading panel while trading is off: "Two signatures in your wallet, once on this browser, no gas: Hypertake's fee (0.1% on perps, 1% on outcome sells; buys carry none), then a trading key." The perps order form has the same button, and Portfolio has a One-tap trading card with Turn on.

2. 2

   Press it and confirm both signatures

   The button reads "Confirm in your wallet…" while your wallet shows the fee approval, then the trading key. Confirm each.

   ResultA "One-tap trading is on" notice appears. The Portfolio card reads On, with the key's expiry date.

#On your phone

1. 1

   Press Buy, or open Account → One-tap trading

   Your first trade with trading off opens Turn on one-tap trading: what you'll sign ("Two messages: Hypertake's fee, then a key that lets this device place orders for you"), what it can't do, how long it lasts, and a preview of the wallet's signature request.

2. 2

   Tap Approve in MetaMask

   (Or your wallet's name.) The wallet app opens twice: Hypertake's fee first, then the key. Confirm both, then come back to the browser. Not now closes the screen without signing anything.

   Result"One-tap trading on · Approved in MetaMask for 179 days". Your trade isn't placed for you: the ticket is as you left it, so press Buy again when you're ready.

#How long it lasts

The key is approved for 179 days; Hyperliquid allows an agent at most 180 days (API wallets). Hypertake reads the real expiry back from Hyperliquid and shows it: the date on the desktop Portfolio card, "N days left" in the phone's Account. When it expires, one-tap trading reads Off and your next trade asks you to approve a new key (one signature, since the fee approval stays).

#Each browser has its own key

• Nothing syncs between devices. Your laptop and your phone each make and approve their own key.
• Hyperliquid limits named keys per account (up to 3, depending on your trading volume). When the account is full, Hypertake reuses the oldest slot that belongs to one of its own keys, which turns one-tap trading off on that other device. It never touches keys from other apps.
• If every slot belongs to another app, Hypertake says so: "Your Hyperliquid account already has its most trading keys…, all from other apps. Remove one on Hyperliquid (More → API), then turn this on again."
• Perps on testnet (chosen in Settings) use a separate key on Hyperliquid's testnet: one signature and no builder fee.

#Turn it off

Hyperliquid has no "revoke" for an agent, so turning off approves a throwaway key under the same name, valid for 60 seconds, which replaces yours; then Hypertake deletes your key from this browser. That's one wallet signature, with no gas and no money moving.

• Desktop: Portfolio → One-tap trading → Turn off.
• Phone: Account → One-tap trading → Turn off one-tap trading, then Turn off in MetaMask (or your wallet).
• From Hyperliquid's own app: More → API lists every agent on your account and lets you remove any of them, including a key on a device you no longer have.
