Hyprr — Hyperliquid Trading

Hyprr is a native mobile client for Hyperliquid — the on-chain perpetuals
and spot exchange. Connect any EVM wallet via WalletConnect, sign locally
with a short-lived agent key, and place orders without ever pasting a
private key or seed phrase into the app.

KEY FEATURES

• Perpetuals trading
Long or short any Hyperliquid perp market with full leverage controls,
take-profit and stop-loss orders, and live position tracking.

• Spot trading
Buy and sell native Hyperliquid tokens (HIP-1, HIP-2, HIP-3) directly
from the on-chain order book.

• Live market data
Real-time candles, order book, recent trades, funding rates, and open
interest — pushed over Hyperliquid's WebSocket, not polled.

• Portfolio at a glance
Open positions, balances, unrealised PnL, and order history for every
linked wallet.

• Native WalletConnect
Link any EVM wallet — MetaMask, Rainbow, Trust, Ledger Live — in
seconds. No proprietary wallet, no account creation.

NON-CUSTODIAL BY DESIGN

Hyprr never sees your main wallet's private key or seed phrase. When you
link a wallet, the app generates a fresh agent key on-device, approves
it once via WalletConnect, and uses it from then on to sign orders
locally. Your main wallet only needs to be online to revoke the agent
if you disconnect.

The agent key is stored in an encrypted on-device database — SQLCipher
on Android with the passphrase in the hardware-backed Keystore, and
NSFileProtectionCompleteUntilFirstUserAuthentication on iOS. The database
is excluded from cloud backup. Optional biometric lock adds a per-launch
unlock step.

PRIVACY

No analytics, no tracking, no advertising IDs. The only data Hyprr ever
transmits to a Hyprr-operated server is anonymised crash reports, with
wallet addresses scrubbed on-device before upload. All Hyperliquid API
traffic is TLS-pinned. Full details: https://hyprr.cat/privacy/

REQUIREMENTS

• An EVM wallet that supports WalletConnect (MetaMask, Rainbow, Trust,
Ledger Live, etc.)
• Funded Hyperliquid account (or use Hyperliquid testnet via the
testnet build)

DISCLAIMER

Hyprr is an independent client and is not affiliated with Hyperliquid
Labs. Trading perpetual futures involves substantial risk of loss and
is not suitable for all users. Use at your own risk; you are solely
responsible for managing your wallet, your positions, and your tax
obligations.
