Follow the whales. Understand the move.
Isobath helps Hyperliquid traders find the large wallets changing risk, inspect what they did before, and get alerted when they move again. No trade calls and no guessing — just the observed position change, the wallet behind it, and the history you need to make your own decision.

$59/month $590/year
or $590/year — 2 months free $49.17/month, billed once
- Everything in Pro
- Unlimited watched wallet-market pairs
- Market rules across every observed wallet, not just your list
- Alert on any top-10 or top-20 observed wallet
- Alert above a position-size threshold you choose

Investigate
Pro Research
$99/month
Indicative. No payment is accepted for this tier.
Go beyond "what happened" and study recurring behaviour.
- Behaviour comparisons across wallets and across time
- Cross-asset wallet analysis
- Repeated accumulation and reduction patterns
- Long-to-short and short-to-long reversal studies
- Crowding and concentration history
- "What happened after similar moves?" analysis
- Exportable research views and saved investigations
What this solves: instead of only asking "who moved?", you can ask which wallets repeatedly behave this way — and what followed.

Pay in crypto while Isobath is early
Pro and Pro+ are paid manually in USDC or USDT on Arbitrum One. From your account, choose a monthly or annual term, request access, send the exact amount to the address shown, then submit the transaction hash. The founder reviews it and activates access, usually within a day. There is no automatic renewal and no card required — annual simply means one transfer a year instead of twelve.
What the two lists in each plan mean
A ticked line is enforced in the product today — you can hold us to it the moment you pay. A dashed line is direction: it is shown so you can see where a plan is going, and it is never something you are being charged extra for now. A capability moves from the second list to the first on the day it is actually enforced, not when it is designed and not when it is partly working.
Why we say "whale" sometimes but always mean "wallet"
A whale here is simply a large observed wallet — ranked by position size within the exposure we actually observed, nothing more. The word says a wallet is big. It does not say it is skilled, profitable or right. That is why every event on the site is stated in precise terms: "observed wallet: rank #7, 3.2% of observed BTC exposure", with the coverage and observation age attached. Familiar language on the outside, exact evidence underneath.
Pricing questions
Pro covers 25 wallet-market pairs. Pro+ removes that limit and adds market rules that watch every observed wallet, including rules for moves that are unusually large for a wallet's own history. These rules are checked every 10 minutes and delivered through Telegram when connected.
Not yet. Pro and Pro+ are paid manually in USDC/USDT for now. Card checkout is a later option once a payment provider is set up.
Whatever you've already built stays yours. If the free watch limit changes, existing users get clear notice before anything is reduced.
Payments are reviewed directly rather than through an automated processor, so activation is usually same-day, not instant.
Yes. Each payment buys a fixed term with no automatic renewal, so you choose again each time rather than being locked in.
No. Market pages, the liquidation watch map, the heatmap, rotation and concentration are public and stay public. Paid plans are for private monitoring, not for access to the market view.
