About Perpys
Perpys publishes one comparable view of the funding rates traders pay on perpetual DEXs. It started with Hyperliquid, Lighter and Aster because those three expose complete public APIs and together cover most on-chain perp volume; Binance and Bybit appear as reference rates.
What it is
- A read-only data site. It pulls public market data every hour, normalises it (methodology) and renders static pages. Nothing is executed on your behalf and no wallet is connected.
- Independent. Perpys is not operated by, affiliated with or endorsed by Hyperliquid, Lighter, Aster, Binance or Bybit. Venue facts are quoted from their documentation with links and a check date.
- Editorial pages (the explainer, venue facts, comparisons) are written and reviewed by the Perpys editorial team and dated. Data pages are generated from the snapshot and carry its timestamp.
What it is not
- Not investment, trading or tax advice. See the disclaimer.
- Not a trading interface and not a custodian.
- Not a real-time terminal: numbers are up to one hour old.
Disclosure
Links to venue apps may carry a referral code, in which case the venue shares a part of the fees of users who sign up through the link, and in some programs the user receives a fee discount. Referral links never alter the data displayed, and no venue pays for placement or ranking on this site.
