Crosschain Hello world dapp with axelar

axelar-crosschain-dapp

This project demonstrates a basic crosschain interoperability using axelar network. Axelar delivers secure cross-chain communication. That means that Web3 developers can create dApps that can interact with any asset, any application, on any chain, with one click. You can think of it as Stripe for Web3.

In this project we will be sending message from smartcontract on avalanche to smartcontract on moonbeam and vice versa.

Rename env.example to .env and add your env specific keys.
