| ## Foundry | ||
| ## Cross-Chain Messaging with Wormhole | ||
|
|
||
| **Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.** | ||
| This project demonstrates how to send and receive cross-chain messages using the Wormhole protocol, specifically between Avalanche Fuji and Celo Alfajores testnets. The repository includes automated scripts for deploying contracts and sending messages across these chains. | ||
|
|
||
| Foundry consists of: | ||
| ### Features | ||
|
|
||
| - **Forge**: Ethereum testing framework (like Truffle, Hardhat and DappTools). | ||
| - **Cast**: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data. | ||
| - **Anvil**: Local Ethereum node, akin to Ganache, Hardhat Network. | ||
| - **Chisel**: Fast, utilitarian, and verbose solidity REPL. | ||
| - Deploy smart contracts on Avalanche Fuji and Celo Alfajores TestNets | ||
| - Automatically manage contract addresses | ||
| - Send a cross-chain message from one chain to another using Wormhole | ||
