The Oasis Privacy Layer (OPL) is a tremendous achievement in interoperability. Powered by Oasis Sapphire, the industry’s first-ever confidential EVM runtime, OPL has two components - the message-passing bridge and the gas relayer. It’s the best way to leverage cross-chain privacy solutions on any EVM web3 dApp, and there’s no need for migrating chains or inconveniencing the users in any way. In fact, the message-passing bridge ensures that all data to and fro are encrypted and signed while the gas relayer ensures the users can pay for the extremely low-cost gas fees for the transactions payable in the native chain’s tokens only.
The Celer Interchain Messaging (IM) messaging framework integrated with Oasis Sapphire that was announced recently will give a great boost to OPL functionality as it will be the key to connecting the native EVM chain and Sapphire. As a result, Solidity developers will be able to leverage the unique confidentiality features of Oasis that offer customizable confidential state and privacy solutions to the dApps.
With these crucial developments now live, OPL functionality to ensure privacy for web3 dApps becomes handy for developers. This is especially great news for those leveraging OPL features for their dApps to be showcased during the upcoming hackathon.
