Telepathy is a protocol built by [Succinct](https://succinct.xyz) that enables interoperability without compromise. Using Telepathy, developers can send messages from Ethereum to any other chain with the security of Ethereum's light client protocol. For the first time, developers no longer need to trust centralized actors or permissioned multisigs when passing information from Ethereum to other chains.

**Overview**

Telepathy's core innovation is a zkSNARK circuit that verifies Ethereum validator signatures, allowing for a gas-efficient light client to run as a smart contract on any EVM chain. This core primitive allows developers to use Telepathy in a few different ways:

* Send messages from Ethereum to any EVM chain: [interchain-messaging](https://docs.telepathy.xyz/build-with-telepathy/interchain-messaging "mention")
* Request arbitrary Ethereum data from any EVM chain: [interchain-data-oracle](https://docs.telepathy.xyz/build-with-telepathy/interchain-data-oracle "mention")
* Access Ethereum consensus data in the execution layer: [intrachain-consensus-oracle](https://docs.telepathy.xyz/build-with-telepathy/intrachain-consensus-oracle "mention")
