How it works

We track a handful of carefully selected top traders ("whales") on Hyperliquid in real time. When a whale opens, resizes or closes a position, your bot mirrors the same move, scaled to your capital: if she puts 10% of her account on a position, the bot puts 10% of yours, at the same leverage. You always see exactly what the bot holds, its PnL, and every action it took.

Paper mode is a full simulation — no real money, no deposit, no Hyperliquid account needed. You choose a virtual bankroll (say $10,000), press Start, and the bot mirrors the whale with simulated fills, including realistic trading fees and slippage. It's the honest way to evaluate the strategy before risking anything.

No — by design, not by promise. The service is non-custodial:

• Your funds never leave your own Hyperliquid account.
• You connect an API wallet, a special key that Hyperliquid restricts to placing trades only — it cannot withdraw or transfer funds, period.
• You can revoke that key at any time on Hyperliquid, or disconnect in Settings.
• Your key is stored encrypted and never displayed again — not even to you.

1. Go to app.hyperliquid.xyz/API (log in with your wallet).
2. Click "Generate" to create an API wallet, give it a name (e.g. "whales-sonar").
3. Authorize it, and copy the private key shown once.
4. In Whales Sonar, paste your master account address (your main 0x… address) and that private key. We verify both with Hyperliquid before saving.

Reminder: this key can trade but can never move funds out of your account.

Your two safety nets, checked every ~15 seconds against your account value (bankroll + PnL − fees):

• Stop-loss: if account value falls to this level, the bot closes every position and pauses itself.
• Take-profit: if account value reaches this level, same thing — gains locked, bot paused.

Each can be enabled independently. They are "soft" stops: in a very fast market the exit can fill slightly past your level, like any stop order.

Selecting whales is our core work: we scan every serious trader on Hyperliquid (38,000+ wallets), filter out wash-traders and lucky gamblers, and grade the rest on risk-adjusted performance — drawdown, consistency, track-record length. The identity of the tracked whales is the product's edge, so we publish their performance (returns, drawdown, current book) but not their address.

Three honest reasons: (1) you started copying later than she started trading, so your entry prices differ; (2) mirroring has a few seconds of latency; (3) fees and slippage. Over time your relative performance tracks hers closely, but the absolute numbers will never be identical.

Nothing. The beta is free and invitation-only. Billing (via Stripe) will arrive with live trading, with notice before anything is charged.
