description: Orion Finance enables private, onchain portfolio management by integrating confidential smart contracts powered by advanced cryptography (FHEVM). Managers can run encrypted strategies, protecting their alpha while keeping results auditable and verifiable onchain. The architecture preserves DeFi’s composability and transparency for users while adding institutional-grade confidentiality for asset managers.

# Orion Finance – Private, Intent-Based Portfolio Vaults (Encrypted Onchain Portfolio Management)

## Fits with patterns

* [Private Intent-Based Vaults](/patterns/pattern-private-vaults/) \- Core use case: encrypted strategy execution while keeping assets auditable
* [Private L2s](/patterns/pattern-privacy-l2s/) \- FHEVM infrastructure for privacy-native portfolio execution
* [Selective Disclosure](/patterns/pattern-regulatory-disclosure-keys-proofs/) \- Auditable performance metrics while maintaining strategy confidentiality

## Not a substitute for

* Public yield vaults or transparent portfolio managers
* Centralized asset management infrastructure

## Architecture

* **Vault Layer:** Encrypted ERC-4626 / ERC-7540 vaults supporting multiple strategies.
* **Execution Layer:** Confidential smart contracts using **FHEVM (ERC-7984)** to keep strategy parameters private.
* **Aggregation:** Gas-optimized batching and netting of transactions.
* **Transparency:** Onchain state remains auditable and composable across DeFi protocols.

## Privacy domains

* Encrypted execution (FHE) for strategy confidentiality.
* Transparent vault assets and verifiable performance metrics.

## Enterprise demand and use cases

* Institutional portfolio managers and hedge funds seeking **onchain strategy execution without alpha leakage**.
* DeFi asset managers requiring **auditable but private** portfolio automation.

## Technical details

* Built with ERC-4626, ERC-7540, ERC-7887, and ERC-7984 (FHEVM).
* Integrates with Zama’s FHE technology for confidential computation.
* Modular vault framework enabling flexible and auditable portfolio creation.

## Strengths

* Protects alpha through encryption while maintaining composability.
* Reduces gas costs via batching and netting mechanisms.
* Auditable, interoperable design for regulated DeFi strategies.

## Risks and open questions

* Scalability and FHE performance overhead.
* Standardization of encrypted intent and strategy formats.
* Long-term interoperability with other privacy L2s.
