Axelar

[Axelar Network](https://axelar.network/) is a cross-chain communication protocol that aims to enable seamless interoperability between different blockchain networks. It is a decentralized network that allows users to transfer assets, data, and value between different blockchain ecosystems. [Axelar Satellite](https://satellite.money/) is a component of the Axelar Network that serves as a decentralized messaging and notification system. It enables the transfer of messages and notifications between different blockchain networks, providing a communication layer that allows users to interact with different chains. [Axelar Squid Router](https://www.squidrouter.com/) is another component of the Axelar Network that acts as a routing system for inter-chain communication. It routes messages and transactions between different chains using a decentralized routing algorithm that ensures reliability, security, and efficiency. The main difference between Satellite & Squid is that on Satellite, users can transfer an asset from 1 chain to another chain, but on Squid, users can transfer an asset from 1 chain to ANOTHER ASSET on another chain. Together, these components enable the Axelar Network to provide a seamless and decentralized way for users and developers to interact with different blockchain networks.
