Gateway is Ostium’s portal for institutional clients who route orders from their own systems. It covers everything around order entry: market specs and live state, master and sub-account margin, risk limits, live positions, reporting and API keys.

  • Everything around the order, nothing in place of it

    Clients keep order entry in their own systems. Gateway shows the market state, margin and limits that inform routing, and keeps one action that matters in a hurry: flattening positions.

  • Exposure in context

    Every market row shows your own exposure beside the venue’s specs. The detail panel puts the venue’s max leverage next to your organization’s cap, so the binding limit is obvious.

  • Limits that inherit

    Risk limits are set for the organization, each asset class, market and account, and lower levels inherit soft and hard utilization limits unless overridden. Needs Attention says what to do before a hard limit hits.

Screener

Filtering and comparing crypto assets.

Coverage
30,000+ assets, 50+ metrics

Messari’s Screener lets researchers and investors filter more than 30,000 assets across 50+ metrics, then save the result as a screen and share it. Most people start from a sample screen, like gainers and losers or a single sector, and make it their own.

  • Filters that read as sentences

    Each filter reads left to right: metric, unit, aggregation, window, operator, value. “Real Volume, USD, 24H sum, greater than $100M” needs no query language.

  • Know what a filter does before you rely on it

    Every filter shows how many assets survive it. Hovering the count splits it into results from that filter alone and results combined with the filters before it.

  • Views over the same screen

    Overview, Volume and Performance swap the column set without touching the filters, so one screen answers several questions.

Messari Design System

Messari

A design system built from scratch.

Four chart components: a scatter plot, a grouped bar chart with a tooltip, a price line chart with volume bars, and a pie chart of funding rounds.

Team
Grew design to five

I joined Messari as its first designer, three years into the company, when the product had no design system. I helped build one from scratch while growing the design team to five people.

  • One chart language

    Scatter, bar, line and pie charts share one frame: a title with an info tip, a YTD, 1Y and ALL range control, a legend, a tooltip with exact values and a data source credit.

  • One module for every feed

    Research, intel and news feeds are the same module: a title, filters, and rows with time, category, related assets and an importance tag.

  • Navigation that searches

    The top nav carries a search that jumps to any asset, with tabs for trending results and entity types, and account and theme settings in one menu.

About

I started in a newsroom, designing internal tools and then the iOS and Android apps at The Washington Post. After a few years freelancing as a designer and frontend developer, I joined Messari as its founding designer, where I helped build the design system from scratch and grow the design team to five.

Now I design and build in code at Ostium Labs. I care about the details that make numbers trustworthy, like figures that line up, loading states that tell the truth, and copy that says exactly what will happen.
