Who it is for

Lê Thu Hà is an air traffic controller in Da Nang who reads radar for a living. Last year she opened a funding trade on a 60 percent spread that fees, slippage and one funding flip turned into a loss. Funding Radar sweeps Hyperliquid, Drift on Solana and GMX on Arbitrum, shows each spread net of fees and slippage, and only pings her when it clears her floor for six hours; if she says yes, it opens a hedged pair inside her caps and unwinds it by her rule.

Why it is new

What exists today, and what this does differently

Why own your own

Funding scanners, alerts and even dual leg execution already exist. What is less common is ranking spreads net of fees, slippage at the user's size and settlement interval mismatch, keeping alerts as the default, and running the hedged pair only inside user caps with a written unwind rule.

Closest things out there

perp-cli (funding arbitrage scans across Hyperliquid, Pacifica, Lighter and Aster with Telegram alerts and dual leg execution), Otomato's funding rate arbitrage scanner (estimates explicitly before fees and slippage), Octav's nine venue funding dashboard, and Chainstack's Hyperliquid funding arbitrage guide.

Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.

What you own

The whole app, not a starter kit.

A funding spread radar you own: users see every spread across Hyperliquid, Drift and GMX net of fees and slippage, get one honest ping when a spread clears their floor, and can open a hedged pair inside their caps. You earn from your own paywall; your console runs pricing, cost assumptions, growth and the sweep agent.

BLUEPRINT

Why it matters and how it really works

The recipe (how it is built, the data, costs, risks, build order, the pitch and the demo script) is unlocked when your app is paid in full.

The need

Funding spreads between perp venues look like free money on dashboards. People open a pair on a raw spread, then fees, slippage on a thin book, a different settlement interval and one funding flip turn it into a loss. Watching rates by hand is a second job.

What exists and what is new

This largely exists. perp-cli scans funding across Hyperliquid, Pacifica, Lighter and Aster, sends Telegram alerts and executes both legs. Otomato ranks spreads but says its estimates are before fees and slippage, and Octav compares nine venues. Funding Radar is an incremental take: every spread is shown net of trading fees, slippage at the user's size, GMX borrow costs and settlement mismatch; alerts are the default; and the optional hedged pair runs only inside user caps with an unwind rule written before entry. Research verdict: exists, low novelty.

The data it runs on

Unlocked when your app is paid in full

1.The mission

Show people what a funding spread is really worth after costs, and make the hedged trade, if they want it, follow rules they wrote while calm.

2.Why people can't resist it

Net, not raw Every blip on the radar is the spread after fees, slippage at your size, borrow and settlement mismatch. A 76 percent raw spread can show up as negative.

One honest ping It only pings when a spread clears your floor and stays there for your persistence window, so a one hour spike does not wake you.

The unwind rule Before any pair opens you write when it closes: net below your floor for two funding periods, or either leg's margin too thin.

8.Where this is going

Now
One person sees which funding spreads are worth a look after costs and gets one ping instead of a day of watching.
Next
More venues, GMX pairs, and a weekly board of spreads that paid after costs versus ones that only looked good.
Later
Shared cost models that anyone can audit, so raw APR stops being the number people trade on.
The world it builds
Funding carry becomes something ordinary people understand, with the costs and the flips in plain view before any money moves.

Costs and tools are estimates at the time of writing. General information only, not legal or financial advice.

Why own Funding Radar

Every perp trader has seen a 60 percent funding spread on a dashboard. Few have seen what it was worth after fees, slippage and the flip three hours later. Owning Funding Radar means you run the honest version: spreads net of costs at the user's size, one ping when one clears a floor, and a hedged pair that only runs inside caps the user wrote. Newsletter writers, trading groups and careful carry traders will pay for the number they actually care about.

What’s stopping you?

“I do not understand funding rates well enough to run this.”

The app explains each spread as a cost breakdown, and the delivery includes a plain guide to funding on each venue. You run the app and the cost assumptions; users decide what to trade.

“What if a user loses money on a pair?”

They can, and the app says so on every pair screen. Pairs are off by default, open only inside the user's caps, and unwind by the user's rule. Funds stay in the user's accounts behind permissions that cannot withdraw. Never market APR as income.

“Are funding scanners not free already?”

Some are, and most show raw spreads. Your edge is the net number at the user's size and the discipline around pairs. Lead with the spreads that looked great and were not; that is what free tools rarely show.

“What if a venue changes its funding model?”

Each venue has its own adapter and the cost model is versioned. GMX already works differently and is modelled separately. If a feed goes stale, the radar stops pinging rather than guessing.
