Resolvium is a purpose-built frontend for HIP-4 prediction markets on Hyperliquid. We give traders a fast, social, self-custodial way to trade outcome markets — UP/DOWN binary contracts on crypto prices, multi-outcome price-bucket markets ("Where will BTC settle on May 19?"), and any other HIP-4 instrument Hyperliquid deploys — without ever taking custody of user funds.
Why we built Resolvium
Prediction markets are one of the cleanest financial primitives in crypto: a market price that is, by construction, a probability. The category has historically been split between two compromises. Polymarket runs on Polygon with USDC and resolves manually via a UMA dispute mechanism — fast UX but a centralized order book and oracle-disputable settlement. Kalshi is fully regulated and centralized, with USD-only, KYC-required access and no programmability.
Hyperliquid's HIP-4 spec creates a third option: outcome markets that trade on a real on-chain L2 order book with full L2 depth, settle deterministically against HyperCore's mark price, and never need a curator or dispute window. The protocol is good. What was missing was a frontend that took the trader experience seriously — alerts, social signal, position management, settled-market history, the boring-but-important plumbing that turns a primitive into a product. That's Resolvium.
What you can do on Resolvium today
Trade the full HIP-4 surface. Every HIP-4 market live on Hyperliquid appears in Resolvium automatically — no listing process, no curation, no whitelist. Today that means hourly, daily, and weekly UP/DOWN binaries on BTC, ETH, SOL, HYPE and other underlyings, plus multi-outcome price-bucket markets. As Hyperliquid deploys new markets, they show up in Resolvium the same minute.
Self-custody by default. Funds stay in the user's Hyperliquid account at all times. We don't accept deposits to Resolvium-controlled wallets and we don't issue IOUs. Users sign in once with SIWE to verify wallet ownership, approve a Hyperliquid trading agent for one-click order placement, and atomically swap USDC ↔ USDH from the account chip. The agent's private key lives in the user's browser only — same delegation primitive Hyperliquid's own frontend uses.
Real-time, multi-channel alerts. Set price-cross alerts (above / below / either-direction) on any outcome. Fires deliver via browser Web Push, Discord webhooks, and a Telegram bot. A dedicated worker subscribes to Hyperliquid's live mid feed and detects threshold crossings within hundreds of milliseconds.
Live social trading. Follow any trader to highlight their fills in the live trade feed. Every market page surfaces an "N you follow active here" strip when followed traders are trading. A dedicated /following feed aggregates every fill from followed addresses over the last 7 days. Trader profiles show a P&L equity curve, full fill history, current positions, and an X/Twitter linked handle.
Market discussion. Every market has a threaded comments section with one level of replies. Discussions get attached to follows-and-replies notifications so users see when someone replies to them or when a market they're watching gets active.
Settled-market history. The trader experience doesn't end at expiry. Every recurring market shows its last 7 settlements as inline chips on the live page (date + winning side + settlement price), each one click-through to a dedicated settled-outcome page with a full historical chart of the underlying — pre-settlement at full opacity, a vertical dashed line at the resolution moment, and the post-settlement region rendered at reduced opacity for context.
Unified notifications inbox. A single bell badge in the top nav for everything: alert fires, follows, comment replies. Push payloads also surface as in-tab toasts when the user is actively viewing the site.
Technical approach
Resolvium is built directly on Hyperliquid's HyperCore order books — no AMM, no curve assumptions, no off-chain matching. Orders are signed by either the user's wallet or their trading agent and submitted to HL via the standard order action. Tick precision goes down to 0.001¢ where the order book supports it.
We attach Hyperliquid's builder code to all routed orders for fill attribution. The per-fill fee is currently 0% while HL's HIP-4 fee waiver is in effect — users sign a one-time builder approval (capped at 0.05% in case fees are introduced later, fully revocable) so HL can attribute fills, but nothing is charged today.
Status
Resolvium is live in beta on Hyperliquid mainnet as of May 2026. The desktop experience is fully shipped — chart, order book, trade ticket, positions, comments, alerts, notifications, trader profiles, settled history. A dedicated mobile app, designed from scratch for the phone rather than a responsive squish of the desktop UI, is in active development; today the event pages show a "Best on desktop" notice below 768px.
