What is the Oasis Privacy Layer?

The Oasis Privacy Layer (“OPL”) is a cross-chain EVM-compatible privacy solution that opens new frontiers for confidential smart contracts in Web3 applications on the most popular EVM networks like Ethereum, BNB Chain, and Polygon.


  • Sapphire provides developers with the unique capability to build EVM-based dApps with on-chain confidentiality.
  • Developers can use Sapphire — the first and only confidential EVM-compatible ParaTime — to build smart contracts that are 100% confidential, 100% public, or anywhere on the spectrum of confidentiality.

Oasis Wallet is the official non-custodial wallet for storing, sending and receiving digital assets on the Oasis Network. With the successful deployment of Oasis Safe by ProtoFire on Sapphire and a partnership with Transak, Oasis users also have access to an industry-leading custody options and easy on-ramps for the Oasis ecosystem.


Oasis Explorer provides an easy-to-use deep dive into on-chain activity from Oasis users and developers. By surfacing powerful data and analytics across all Oasis runtime environments, the Explorer queries data for users to analyze the growth and development of Oasis.


Oasis Nexus is the official indexer tool for the Oasis Network and the backend for explorers and wallets. Nexus continuously fetches blockchain data from one or more Oasis nodes, parses the data and stores it into a heavily indexed SQL database, which provides a JSON-based web API to access the data.
