How it works

Your wallet approves.
Your device trades.

Funding and withdrawals stay on the wallet authorization path. The scoped key held by the device is separate from your wallet key.

  1. 01

    Connect or create

    Start with a compatible wallet or hosted sign-in.

  2. 02

    Approve access

    Your wallet authorizes a separate trading credential.

  3. 03

    Fund explicitly

    Value movement remains a wallet-authorized transaction.

  4. 04

    Trade locally

    The scoped key signs permitted read and trade requests.

The boundary

A trading key is not a wallet key.

It can read account state and place or manage orders within its approved scope. It cannot withdraw, transfer value, or reveal the wallet key that authorized it.

Details that matter

Built to keep the important things obvious.

103,250.0Mark

Exact values stay exact

Amounts, units, entry, mark, margin, fees, and risk controls remain visible as the interface adapts.

LIVE

State has a voice

Loading, stale, failed, and recovered data should never masquerade as a confident zero.

44pt

Made for a thumb

Large targets, clear hierarchy, and mobile-native controls keep the workflow reachable.

↻RETRY

Recovery stays close

When networks or providers fail, the next safe action is visible instead of hidden.

Questions, answered

The important parts.

Is Amethyst the PERPL exchange?

No. Amethyst is an independent mobile interface. PERPL provides exchange infrastructure and execution; Monad is the network where activity settles.

Can the device trading key move funds?

No. The credential is scoped to account reads and trading requests. Deposits and withdrawals remain wallet-authorized actions.

How do I revoke a device credential?

Removing the local credential signs out trading from that device, but it does not revoke the server-side key. Manage the key directly through PERPL key management ↗.

Does the beta use real assets?

The currently distributed private beta uses Monad mainnet. Assets, fees, gains, losses, and finalized transactions can have real value. The interface screenshots on this design page use sample data.

Does Amethyst guarantee a fill or outcome?

No. Execution depends on protocol, network, market, liquidity, order, and account conditions. Perpetuals involve substantial risk.
