Axelar Deep Dive: Cross-Chain Pioneers

BY ICISept 8 · 3 min read

1. Introduction to Axelar

Axelar is a groundbreaking platform designed to bridge the gaps between various blockchains, enabling seamless and secure cross-chain communication. At its core, Axelar aims to empower the development of decentralized applications (dApps) that can operate beyond the confines of a single blockchain. This is achieved through a combination of gateway smart contracts, validators, and relayer services.

Overview: Axelar is not just another blockchain platform; it’s a cross-chain communication powerhouse. By leveraging a proof-of-stake model, Axelar provides developers with the tools they need to interact with smart contracts across different chains using popular programming languages like Solidity or JavaScript. Whether it’s sending fungible tokens between Cosmos and Ethereum Virtual Machine (EVM) chains or more complex transfers, Axelar has it covered. One of its standout features is the General Message Passing, which facilitates calling smart contract functions across blockchains.

Gateway Smart Contracts: These contracts are pivotal to Axelar’s operations, enabling it to relay messages across all connected chains. Each EVM chain linked to the Axelar network boasts a Gateway contract, which is instrumental in transmitting messages from Axelar to the associated chain. This contract is governed by a key, maintained collectively by all Axelar validators through a sophisticated multi-party cryptography scheme.
Validators: Validators are the backbone of the Axelar network. They not only participate in consensus, producing blocks, and validating transactions like other proof-of-stake chains but also oversee all cross-chain activities processed by the network. This dual responsibility mandates Axelar validators to run nodes for supported chains and monitor those external chains for activity.
Relayer Services: These are optional services provided by Axelar to facilitate cross-chain communication. While they can be executed by anyone, they play a crucial role in ensuring smooth communication across chains.
Developer Tools: Axelar goes the extra mile to support developers. It offers a plethora of tools, including a curated collection of interchain examples and the Axelar JavaScript SDK. Developers can also simulate chains locally, deploy custom contracts to simulated EVM chains, and test their dApps against local RPC endpoints.
