5x leverage

One portfolio
across every market

Positions across

Centralized exchanges

Decentralized exchanges

On-chain venues

Traditional financial markets

including Binance, OKX, Hyperliquid, US equities and CME futures, sit under one portfolio margin

Collateral stays where each market requires it and still counts toward the same portfolio, under a single onboarding.

5x leverage

Capital efficiency
across
the whole book

A gain on one venue offsets a loss on another before Arkis calculates margin, so the same book requires less collateral and releases capital that would otherwise sit idle.

Up to 5x leverage

Against a diversified portfolio

Settlement runs around the clock

USDC and USD settle instantly, at any hour, so margin can be rebalanced across venues without waiting for banking hours.
