What is Axelar?
Axelar is for Web3 what Stripe is for mobile and internet applications: it works on the back end, connecting various networks into one-click experiences for all users. The Axelar stack provides a decentralized network, protocols, tools, and APIs that allow simple cross-chain communication.
Axelar delivers secure cross-chain communication for Web3. Secure means Axelar is built on proof-of-stake, the battle-tested approach used by Ethereum, Cosmos, Avalanche, and more. Cross-chain communication means you can build a complete experience for your users that lets them interact with any asset, any application, on any chain with one click.
The two layers of Axelar
Axelar consists of two layers: The network and the API above it.
At Axelar’s core is a permissionless overlay network. It delivers Turing-complete cross-chain communication via proof-of-stake and permissionless protocols. Axelar validators monitor gateways on the interconnected chains (smart contracts) and run a decentralized protocol to process cross-chain messages between them.
The Axelar network explained
Developers go cross-chain without new programming languages. Once integrated, all new interconnected blockchains automatically become interoperable with the application, enabling limitless network effects.
Axelar enables developers to send any payload: a cross-chain message can call a function on another chain and integrate it into a one-click experience for any user, holding any asset. We call this General Message Passing.

Axelar uses permissionless protocols, the Cross-Chain Gateway Protocol (CGP, analogous to Border Gateway Protocol) and the Cross-Chain Transfer Protocol (CTP, analogous to File Transfer Protocol) to provide uniform security, translation and routing across any two connected chains.
Learn how Axelar’s protocols work
Axelar network security is based on delegated proof-of-stake, which means a dynamic validator set using similar consensus to the networks Axelar connects.
