Introduction to Axelar

Axelar is a decentralized cross-chain communication network that connects different blockchain ecosystems. Built on Cosmos SDK with its own validator set, Axelar provides secure cross-chain message passing and asset transfers, serving as a universal translation layer between blockchains.

Founded by Sergey Gorbunov and Georgios Vlachos, both with cryptography backgrounds from MIT and Algorand, Axelar approaches interoperability as a core infrastructure problem. The network connects over 50 blockchains including Ethereum, Cosmos chains, and various L1s and L2s.

The Cross-Chain Infrastructure
