With Celer's messaging bridge full integration with Oasis' Sapphire Runtime network, now it is apparent the possibility to connect 2 different networks, and enable the benefits of one into another. This crypto breakthrough brings a broad collection of new use-cases to the table.
And in the context of Privacy. Integrating celer's bridge with Sapphire, the first confidential EVM in the industry, allows for other EVM blockchains to be able to connect directly with Sapphire, for dApps to be able to leverage confidential smart contracts and provide new use cases for their users in their home chain, without ever having to leave it.
* Harry Roberts made a very detailed workshop to understand how the Oasis Privacy Layer works, and how to built two linked smart contracts, one in the home chain, and one in Sapphire:

The Oasis Indexer Nexus allows this, here you can check events, transactions and details from an account, on both its Oasis and Ethereum addresses. This tutorial provided by Oasis Engineer Xi teaches about the use cases of the Oasis Nexus Indexer:
