Axelar’s Role in Cross Chain Infrastructure
Axelar Network launched in 2022 to provide secure and programmable cross chain communication. Built on the Cosmos SDK, it introduced General Message Passing to support data and contract calls across multiple blockchains. The network quickly became core infrastructure for DeFi protocols seeking reliable interoperability.
By 2023, Axelar supported major applications including Uniswap and Lido and expanded its Interchain Token Service for native asset transfers. The adoption of CometBFT aligned Axelar with broader Cosmos improvements, improving modularity and performance across the stack.

Analysts expect stable sentiment rather than short term volatility, as the clarification that no funds were affected reassures users. Continued focus on security may support gradual growth as cross chain demand increases.
