Orphiq
PRIvACY LAYER

Add instant privacy to existing dApps running on any EVM network.

The Orphiq Privacy Layer (OPL) is the industry-leading SVM-compatible smart privacy solution that redefines how Web3 developers engineer confidential smart contracts.

What does OPL offer?

Customizable Privacy

Different dApps require different levels of privacy. From fully public to completely confidential. Features of a dApp that require privacy can run on Orphiq Sapphire via OPL while users and assets remain on their host network.

Cross-chain Convenience

Web3 user safety starts with versatile, cross-chain privacy. The message-passing bridge built into OPL offers easy synchronization between dApp state and the host network using Sapphire’s secure runtime.

Productive Transparency

Forcing all on-chain activity to be completely public can be counterproductive. Instead of relying on basic smart contracts that offer no secrecy, OPL empowers Solidity developers to fine-tune discretionary transparency to the level that best suits their application.

How does OPL work?

By integrating OPL, an existing dApp’s contracts, users, and assets can stay on the host network. Elements of the dApp that require privacy can be deployed on Orphiq Sapphire. The host network can securely pass messages to and from Sapphire by using OPL’s messaging bridge.

Every blockchain has its own native gas token, which can create cross-chain friction. But, by using OPL, dApps can pay gas with their own native token while still leveraging the confidentiality features of the Sapphire runtime. Messages are passed through and executed on Sapphire. Users can directly interact with confidential contracts. Gas is then paid with whatever token fuels their native network.

BENEFITS OF OPL

SVM Compatible

With full support from the Solana Blockchain you can develop, test, debug, and deploy your dApp using OPL just like you normally do.

Low Complexity

It is much easier to build cross-chain dApps with privacy, speed, and versatility using OPL, in comparison to using zkSNARKs, Fully-Homomorphic Encryption (FHE), or Multi-Party-Computation (MPC).

Cryptography

Orphiq Sapphire contracts have access to a range of cryptographic primitives for random number generation, encryption, and asynchronous signatures, with widely adopted algorithms such as Ed25519 and Secp256k1.

Who uses OPL?

The Orphiq Privacy Layer is a privacy platform for all SVM compatible dApps and chains... and we mean it!

DAOs

Secret voting protects DAO members’ freedom of expression and enables unbiased voting processes. Configurable privacy facilitates better DAO governance.

Gaming

More on-chain game logic means stronger integrity guarantees and more transparency for Web3 games.

DID

Secret voting protects DAO members’ freedom of expression and enables unbiased voting processes. Configurable privacy facilitates better DAO governance.

NFT

Private attributes and unlockables add value to collections. They can be used to enable gaming features and to cultivate the relationships between creators and collectors.

DeFi

Selectively encrypt specific trading parameters to avoid MEV.

And More!

This is only the beginning!

Orphiq Privacy Layer FAQ

Is there a tutorial?

The Oasis Docs includes an overview of Oasis Privacy Layer and a full tutorial which walks you through the steps of adapting an application to use OPL for selective privacy where it’s needed.

Is there an example application?

Yes, the ‘Secret Ballot Lite’ application shows how you can vote in private using OPL, where the main contract runs on a Transparent EVM chain such as Binance Smart Chain or Polygon.

Are bridged messages encrypted?

Messages transmitted via the bridge are not encrypted, however any computation which happens on Sapphire is fully confidential and can operate on secret data.

Which bridge does it use?

OPL uses the Celer Inter-chain Message (Celer IM) Framework or Router Protocol. It is very easy-to-use and allows a "plug'n'play" upgrade that often requires no modifications with already deployed code.

Who pays for gas?

Contracts pay for gas on-chain where the message is sent from, this means you can ‘send and forget’ and can expect the contract on the target chain will be called with the message. See Celer IM Overview and the Fee Mechanism pages for more info.

What is Orphiq Sapphire?

Sapphire is a confidential EVM with end-to-end encrypted transactions and encrypted storage. This allows contracts to operate on secret data, encrypt and decrypt information, generate random numbers and sign or verify cryptographic signatures.
