Our story

We come from traditional financial markets, where we built our careers across quantitative and discretionary trading. We’ve seen what mature markets look like — infrastructure and data optimized over decades, and credit systems designed to scale capital efficiently.


When we looked closely at crypto, we saw the other extreme: crypto deli vered global, 24/7 markets and rapid innovation, but its financial plumbing lagged behind. Like credit — the lifeblood of every financial system — remained fragmented, over-collateralized, and inconsistent across venues.


We recognized the pattern: markets can innovate quickly, but they only mature when credit, margin, collateral, and risk are governed under a coherent framework.

That is the layer we are building.

As on-chain settlement expands across derivatives, collateral, real-world assets, and global markets, Arkis is being built to unify how risk is priced and how credit scales — building the infrastructure that allows prime brokerage to operate in digital markets.

Arkis is built on a set of principles that define how it works:

1. Capital Preservation First, Yield Second
2. Zero-trust risk management over pricing
borrowers’ trustworthiness
3. Predictability beats speculation
4. One standard for all assets and venues.
