The Oasis Privacy Layer (OPL) is an 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.
The Oasis Privacy Layer is a privacy platform for all of Web3… and we mean all of it.
Powered by Sapphire, OPL brings the first confidential EVM with interoperable on-chain privacy to Web3.
Different dApps require different levels of privacy. OPL offers customizable privacy, from fully public to completely confidential. It’s privacy for everyone, the way they want it. Only the parts of your dApp that need privacy run on Sapphire while your users and their assets stay on the home chain.
Full-spectrum on-chain privacy matters for all Web3 users on every blockchain. OPL delivers versatile cross-chain privacy tools to any Layer 1 ecosystem for a safer Web3 experience. With a built-in message-passing bridge, it's easy to synchronize dApp state between the home chain and the OPL secure computing environment.
Transparency is not an all-or-nothing feature of Web3, and forcing all on-chain activity to be completely public, as is the case with traditional smart contracts, can be counterproductive. OPL empowers every Solidity developer to finetune the level of discretionary transparency that suits their application.
