Equito is a cutting-edge cross-chain messaging protocol designed to facilitate seamless, secure, and efficient communication across diverse blockchain networks. As a gateway for interoperability, Equito empowers developers to extend the functionality of decentralized applications (dApps) beyond the constraints of single blockchains.
This repository provides the smart contracts required for EVM-compatible networks to interact with the Equito cross-chain messaging protocol.
- Router, which handles message sending and receiving. Equito Validators listen to events emitted by Routers and perform consensus operations to generate proofs for cross-chain messages validation.
- EquitoApp, which abstracts interaction with the Router and other standard practices to simplify the development of cross-chain applications. Under the hood, it implements the IEquitoReceiver interface to handle incoming messages.
- ECDSAVerifier, which verifies ECDSA signatures produced by the Equito Validators for individual and batched cross-chain messages. Under the hood, this contract implements IEquitoVerifier that provides a standard interface for signature verification, and IEquitoFees, used to calculate fees for sending a cross-chain message.
The examples directory contains:
- PingPong, featured in the Build my first Equito App tutorial, demonstrates how to send and receive messages using Equito.
- CrossChainSwap, a simple implementation of a cross-chain swap between two networks, demonstrating how to send and receive messages using Equito.
In addition to the contracts, this repository includes tests to ensure their correct functionality, and scripts to simplify the deployment and interaction with the contracts.
