  • Enhancing Web3 Privacy and Security with Oasis Privacy Layer

In the rapidly evolving landscape of blockchain technology, ensuring both privacy and security has become a paramount concern. The Oasis Privacy Layer (OPL) emerges as a groundbreaking solution, offering a new dimension to smart contracts on major EVM-compatible networks. This article delves into the key aspects of OPL, shedding light on the problems it addresses, its purpose, notable features, and its compatibility with various networks.

Solving Privacy Challenges on EVM-Compatible Networks

The Challenge:

One of the critical challenges faced by blockchain developers is maintaining user privacy and data confidentiality while executing transactions and managing state. Traditional blockchain networks, like Ethereum, often lack robust privacy mechanisms, leaving sensitive data exposed on-chain.

The Solution – Oasis Privacy Layer:

Oasis Privacy Layer (OPL) steps in as a powerful privacy solution designed specifically for EVM-compatible networks. OPL empowers developers by providing the tools to integrate encrypted transactions and confidential state into their smart contracts. This innovative approach ensures that sensitive information remains private and secure, a feat not easily achievable on standard blockchain networks.

Purpose and Functionality of Oasis Privacy Layer

Empowering Developers:

OPL’s primary purpose is to empower developers to enhance the privacy and security of their decentralized applications (dApps). It allows developers to augment the functionality of smart contracts on popular EVM networks like Ethereum, BNB Chain, and Polygon, all while ensuring that user data is shielded from prying eyes.

Confidentiality and Selective Disclosures:

OPL introduces the concept of “confidential state” and “selective disclosures.” This means that dApp developers can leverage OPL to include confidential data within their applications, which remains hidden from public view. Additionally, developers can choose to reveal specific data selectively, enhancing privacy control while maintaining transparency when necessary.

Notable Features of Oasis Privacy Layer

OPL boasts an array of features that make it a compelling choice for developers seeking to bolster the privacy and security aspects of their dApps:

  1. Encrypted Transactions: OPL enables encrypted transactions, ensuring that the details of each transaction are accessible only to the relevant parties, maintaining the confidentiality of user interactions.
  2. Confidential State: Developers can integrate confidential state within their dApps, safeguarding sensitive data from unauthorized access and providing users with an added layer of privacy.
  3. Selective Disclosures: OPL empowers developers to disclose specific information on a need-to-know basis, striking a balance between privacy and transparency.
  4. Cross-Network Communication: Smart contracts deployed on OPL can seamlessly communicate with other networks, thanks to its default bridge feature. This enhances interoperability and opens doors for innovative cross-chain applications.

Supported Networks

OPL is compatible with several prominent EVM-compatible networks, including but not limited to:

  • Ethereum
  • BNB Chain
  • Polygon

This compatibility ensures that developers across different blockchain ecosystems can leverage OPL’s privacy features without the need to migrate their existing applications.

Integration into Existing Apps

Integrating OPL into existing dApps is a streamlined process:

  1. Developers deploy OPL’s set of smart contracts that incorporate Sapphire, OPL’s underlying technology, into their current or future Web3 applications.
  2. These smart contracts enable the addition of confidential state and selective disclosures without requiring a full application stack migration.
  3. OPL acts as a bridge, facilitating communication between Sapphire-enabled dApps and other networks, further enhancing the versatility of the integrated applications.


The Oasis Privacy Layer stands at the forefront of blockchain privacy solutions, addressing the long-standing challenge of maintaining confidentiality on EVM-compatible networks. Its ability to empower developers to add encrypted transactions, confidential state, and selective disclosures to their dApps, all while maintaining compatibility with various networks, marks a significant step towards a more private and secure decentralized future.
