Whales Sonar vs Hyperdash
Hyperdash (now part of pvp.trade) is a full trading terminal and analytics suite with a copy-trading module built in. Whales Sonar is built around one thing: a faithful, non-custodial mirror of a single proven trader. Here's how the copy mechanics actually differ, so you can pick the fit.
| Copy mechanics | Whales Sonar | Hyperdash |
|---|---|---|
| Sizing model | Strictly proportional: your position is her position's exact size scaled to your capital, at her leverage, one whale at a time. | Exposure-based: combines the traders you follow into one blended portfolio and can cap the resulting leverage rather than mirror it exactly. |
| Custody | Your own wallet. A Hyperliquid API key can trade but is cryptographically unable to withdraw. Funds never leave your account. | Copy-trading runs on a wallet Hyperdash provisions for you, which you then fund. |
| Fee | 0.045% (4.5bp) builder fee, no subscription. | 0.05% (5bp) builder fee on copy trades, per their in-app fee approval screen, with a tiered cashback program. |
| Account required | Wallet-only, no email, ever. | Google, Apple, email, or wallet. |
| Stopping a copy | Stopping closes your positions (a real exit, not just a pause). | Per their own FAQ, stopping prevents new trades but does not close positions already open. |

Why proportional-only, no blending
Blending multiple traders into one portfolio and capping the resulting leverage is a reasonable product choice, it smooths the ride. It is also, by construction, no longer a copy of any single trader: the whole point of following a specific proven account is that her sizing and leverage decisions are exactly what you're paying to inherit. We chose to never touch that, on purpose, even when it would look smoother on a chart. If you want a diversified mix instead of one whale, the Basket in the app runs several traders side by side, each still copied faithfully and independently, no blending inside any one of them.
Why your own wallet, not a provisioned one
An API-key-only wallet is more setup than a login-and-go account, that trade-off is real. It also means we are structurally unable to hold, move, or lose your funds, there's no custodial step to trust in the first place. If the extra minute of wallet setup is the blocker, the free paper simulator gets you the exact same copy experience with no wallet at all.
Same exchange, same fee primitive
Both products monetize through Hyperliquid's own builder-fee system, a per-order fee capped by the exchange at 0.1% and paid on-chain. Neither product can undercut that ceiling by much; the honest way to compare is the rate itself (4.5bp here) and what you get for it.
