Tell me more about Hashi

<aside> 💡

Hashi is a robust and innovative EVM hash oracle aggregator designed to significantly enhance the security of cross-chain applications. It leverages multiple independent oracles to validate and verify block headers and messages across different blockchain networks, ensuring a more secure and reliable way to facilitate interactions between chains.

Build with Hashi

  1. Hashi template offers a set of smart contracts, deploy scripts, and off chain components that supports Hardhat and Foundry. There are two major use cases for Hashi:
    1. Message Dispatching: Dispatching message from source chain and execute the message on target chain.
    2. State Verifying: Verifying a storage proof or event proof from source chain on target chain.
