SHADOW at shadow.freedomcore.io

Single-page Hyperliquid copy-trading terminal. Live SSE whale-fill stream, consensus engine, tier-weighted Kelly sizing, sub-2-second LCP. The hardest single-page UI in the family — and arguably the most readable.

The brief

SHADOW had a working trading engine, but no public face. Hyperliquid is on-chain — every fill from every wallet is verifiable — and SHADOW had been profiling the top 75 wallets and copy-trading their consensus moves for weeks. The terminal needed to render that consensus live, with whale fills streaming in real time, without ever feeling cluttered or slow.

What we shipped

One page. Five sections. Each section pulls live data:

Consensus. When N+ tracked whales agree on the same trade in the same window, SHADOW fires. The consensus card shows the active signal, contributing whales, and risk-manager state.

Whale Roster. 75 tracked Hyperliquid wallets, ranked by quality score. Tier 1 / Tier 2 / Tier 3 visible, recent fills next to each address.

Live Fill Feed. Server-sent events stream every whale fill as it lands. Sub-second latency from Hyperliquid's order-flow stream.

Our Book. Honest equity curve and recent positions taken on SHADOW's own capital. Tiny capital. Honest logs. Losses included.

About. The architecture explained in plain English. Why 5% per position, 25% of equity, daily-loss halt at −5%.

Tech stack

Front-endHand-coded HTML, CSS, vanilla JS — single page, no SPA framework, no build step.

BackendFlask 2.x on 127.0.0.1:8092, behind nginx with SSL termination + security-headers snippet.

Live dataServer-Sent Events on /stream for whale fills. JSON endpoints for consensus, whales, equity, positions.

DatabaseSQLite — smart_syndicate.db with tracked_wallets + fills tables, profiled every 6 hours by the SHADOW quality engine.

SEOSoftwareApplication + WebSite schema, GSC verified, sitemap.xml, robots.txt blocking /api and /stream from crawl.

PerformanceSub-2-second LCP on mobile. Critical CSS inline, fonts preloaded, video hero with poster, no third-party JS.

Outcomes

Two weeks from spec to live. Sub-2s mobile LCP. SSE stream sustains every whale fill across 75 tracked addresses without a frame drop. Sister system to MAVERICK, sharing the same engineering bar. Live demo at shadow.freedomcore.io; the underlying wallet rankings publish on ARENA.
