Overview
Live perp funding rates across 10 exchanges — APRs, cross-venue spreads and carry signals in your browser side panel.
he funding-rate screener every perp trader keeps a tab open for — now pinned to your browser instead. Click the toolbar icon and the ticker opens in Chrome's side panel, next to whatever you're doing: 📊 CROSS-VENUE APRs — current funding on BTC, ETH, SOL, and the other majors across 10 major derivatives exchanges, annualized so venues wi th different funding intervals are actually comparable. ↔️ SPREADS AT A GLANCE — for every asset: the venue where longs are cheapest, the venue where shorts get paid most, and the spread between them. Sort by spread, max APR, or alphabetically. Hover any row for every venue's rate. 🔔 BADGE SIGNAL — the toolbar badge always shows the widest cross-venue spread on the board, refreshed every 5 minutes, even when the panel is closed. When funding dislocates, you see it without opening anything. Data comes from Tessen's own cross-exchange aggregator (one HTTPS request to api.tessen.ai every 5 minutes — that's the extension's only network traffic). No account. No sign-up. No tracking. No wallet connections, ever. Funding APRs are annualized from current rates and change every funding interval. Informational only — not financial advice. Built by Tessen (tessen.ai), the platform that grades trading strategies on out-of-sample data — honestly, including our own.
