Axelar is a programmable blockchain interoperability layer that facilitates secure inter-chain communication, enabling seamless interaction with assets and applications across different chains. Axelar provides a secure cross-chain communication method for Web3 environments, allowing dApp users to easily interact with assets or applications on any chain. It essentially acts as a bridge between blockchains, facilitating full Web3 interoperability. To ensure the security of transactions, the network uses a proof-of-stake (PoS)-based mechanism and uses an open protocol to handle the routing and conversion of messages. Axelar can be regarded as Stripe in the Web3 field. It consists of a decentralized validator network, a secure gateway contract, a unified translation mechanism, a routing system, and a complete set of software development kits (SDKs) and application programming interfaces (APIs). , aiming to achieve interconnectivity and composability between different blockchains. This way, developers can develop on the platform that best suits their project needs, while still having access to users, assets, and applications in other ecosystems. They rely on a network architecture with a unified code base and governance structure rather than a single cross-chain bridge.
