## Description

In this talk we'll discuss how Polkadot's interoperability protocol works at a high level. And we'll go into more details of how this can be used to access Moonbeam's EVM from a different chain. This opens a new realm of possibilities, as contracts in Moonbeam can access app-specialized blockchains inside the Polkadot ecosystem. But also, these specialized chain can tap into Moonbeam's EVM and all the benefits smart contracts offer.
