# One-time approval

> The single signature behind one-click hedging on Hyperliquid.

Today Offset is read-only. It surfaces the markets and links you to the venue,
where you place the trade yourself. As one-click hedging on Hyperliquid rolls out,
here is how it stays non-custodial.

Hyperliquid orders cannot be signed directly by a normal browser wallet, so the
first time you place a hedge on Hyperliquid you approve an Offset **agent** with
one signature. After that, placing a hedge needs no wallet pop-up.

### What you are approving

* An **agent (API) key** generated in your browser. It is created on your device
  and is never sent to or held by Offset.
* The agent can **place the hedges you choose** on Hyperliquid, but **cannot
  withdraw or move your funds**.
* You approve it **once**. Clearing your browser data removes it, and you approve
  a new one next time.

<Info>
  The agent only places trades you initiate, can never touch your balance, and is
  yours alone. See [Non-custodial](/non-custodial).
</Info>

Until then, holding a cover means tapping through to the venue (Polymarket today)
and placing it there yourself.
