Axelar

Axelar is a decentralized cross-chain communication network that enables secure interoperability across 80+ blockchains including EVM chains, Cosmos, Solana, Sui, Stellar, and XRPL. The network provides General Message Passing (GMP) for arbitrary cross-chain contract calls, the Interchain Token Service (ITS) for deploying and bridging tokens across chains, and the Axelarscan API suite for querying network state, validator metrics, token transfer status, and GMP transaction data. Developer tooling includes the AxelarJS SDK, the Mobius Development Stack (MDS), and Axelar Virtual Machine (AVM).

Axelar publishes 4 APIs on the APIs.io network, including Chains API, Contracts API, Health API, and 1 more. Tagged areas include Blockchain, Cross-Chain, Interoperability, Web3, and General Message Passing.

The Axelar catalog on APIs.io includes 1 Spectral governance ruleset.

Axelar’s developer surface includes documentation, GitHub presence, engineering blog, and 10 more developer resources.
