# Verifying foreign event

This example demonstrates the validation of a `Transfer` Event from an ERC-20 contract on the Sepolia network using an event proof on the Chiado network. The proof is retrieved via an API call and provided to a custom contract to be deployed on Chiado. The contract utilizes the `HashiProver` helper library to verify the proof against the latest block header recorded in Hashi.
