Arkis is a capital-efficient prime broker for digital markets powered by a unified margin, collateral, and risk framework built for institutional scale.


Arkis enables institutional trading firms to access leverage across CeFi and DeFi through a portfolio-level margin system.


Instead of managing fragmented margin across venues, borrowers operate through one unified risk framework.

Borrow

Most credit in digital markets still operates on fragmented logic.

Positions are margined:

Positions are margined:

  • Per venue

  • Per asset

  • Without recognizing diversification

This leads to:

This leads to:

  • Capital locked in redundant margin buffers

  • Lower usable leverage than portfolios can support

  • Liquidations triggered by asset pairs, not portfolio risk

Arkis replaces isolated margining with portfolio-level margin

Risk is evaluated across the entire portfolio:

Exposures are netted

Diversification is recognised

Margin requirements reflect aggregate risk

One margin framework across CeFi and DeFi

Arkis opens a unified account clusters for clients across CeFi and DeFi execution venues.

Borrowers trade across venues while Arkis manages collateral and risk at the portfolio level.

Permissioned access: borrowers are pre-qualified before using leverage.

Underwritten assets: only Arkis-approved collateral enters the system.

All whitelisted positions — regardless of where they are executed — feed into:

  • A designated liquidity pool

  • Arkis risk engine

  • One portfolio level margin and liquidation system

Positions across CeFi and DeFi are consolidated through Arkis margin accounts, combining smart contracts with CeFi sub-accounts under a single risk umbrella.


Borrowers can also create multiple margin accounts to isolate risk, while retaining the ability to consolidate positions under one portfolio framework if needed.

Borrowers execute trades via Direct Market Access on:

  • Centralized exchanges (CeFi)

  • On-chain protocols (DeFi)

RISK CONTROLS

Arkis continuously evaluates margin at the portfolio level across all positions and venues.

Risk is managed through a structured sequence:

Portfolio evaluation based on aggregate exposure

Predefined margin thresholds that recognise diversification

Auditable margin controls as risk approaches limits

Automated protective actions

When portfolio health factor approaches defined thresholds, Arkis applies structured margin controls based on predefined, auditable rules. These controls are designed to prompt corrective action early and preserve portfolio stability as market conditions change.

Governed collateral framework

Arkis’ capital efficiency is built on disciplined collateral governance.
Only whitelisted assets contribute to portfolio margin.
Assets are onboarded through a framework that evaluates:

Pricing and liquidation mechanisms

Liquidity depth

Volatility behavior

Correlation with existing collateral

Performance under market stress
