Built by traders who got liquidated the hard way.
In 2021, Eden Park was running a small perpetuals book out of Lower Manhattan when he noticed the gap: the risk data his desk tracked internally — funding rate environment, cascade zones, oracle quality — simply wasn't surfaced anywhere before you opened a position. Aark is that gap filled.
The risk data that lives inside institutional desks. Without being inside one.
Before opening a perpetuals position, a serious OTC desk checks three things: the funding rate environment across protocols, where the nearest liquidation cascade cluster sits, and whether the mark price oracle is running clean. None of that is available in real time on any retail trading interface.
Aark reads the same on-chain state those desks read, normalizes rates across protocols with different settlement intervals, models the forced-selling cascade, and surfaces it through a terminal and API that any trader can access directly. We are not a trading platform. We are not a general DeFi analytics dashboard. We are a pre-position risk tool for perpetuals.
Our users include solo perpetuals traders managing six-figure books and growing trading desks running institutional flow. The common requirement: know the cascade zones and the oracle state before the order goes in.
Meet Eden Park
Eden built Aark's first data pipeline in 2021, drawing directly from tooling he'd built while trading perpetuals at a New York OTC desk. The core observation: funding rate normalization, cascade simulation, and oracle quality scoring existed inside well-run desks — in spreadsheets and internal scripts — but not as a product any external trader could access before a position was opened.
Before Aark, Eden spent several years at two trading firms in New York's Financial District focused on systematic derivatives strategies for on-chain markets. His background is in applied mathematics with an emphasis on stochastic modeling and quantitative risk.
"The data was always there on-chain — public, computable, sitting in protocol contracts. What was missing was the normalization layer and the cascade model on top. That's what Aark is. We didn't invent new data. We surfaced what was already there."
How we build.
Every number we surface shows its source. You know which oracle, which block, which timestamp. No black-box score that you have to trust without understanding.
We don't show you "safe" when the cascade risk is building. Real-time means honest — including when the data shows conditions that make a position more dangerous, not less.
OTC desks depend on this data when positions are live. Uptime is not a feature — it is the baseline. We build to the reliability standards of financial data infrastructure, not consumer software.
