Axelar
Axelar is a decentralized interoperability network that enables cross-chain communication and asset transfers between different blockchain ecosystems. It provides a universal overlay network with a proof-of-stake consensus mechanism, allowing developers to build applications that can interact seamlessly across multiple chains like Ethereum, Cosmos, Avalanche, and others. The platform includes tools such as the Axelar Gateway for connecting smart contracts and the Axelar Satellite for user-friendly cross-chain transfers.
Developers should learn Axelar when building decentralized applications (dApps) that require interoperability across multiple blockchains, such as for cross-chain DeFi, NFT bridging, or multi-chain governance. It is particularly useful in scenarios where users need to move assets or data between ecosystems without relying on centralized bridges, as it offers a secure, decentralized solution with broad chain support and developer-friendly APIs.
