Axelar Core 1.3.5 update fixes a CometBFT vulnerability and improves network security across mainnet and testnet nodes.
Author: Akshay
December 16, 2025. The Axelar Core 1.3.5 Update has been released for both mainnet and testnet nodes, addressing a security vulnerability in CometBFT, the consensus engine used across Cosmos based chains. The release also resolves a non critical issue in the rewards module, improving overall stability.
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.
The Axelar Core 1.3.5 Update highlights the network’s proactive approach to infrastructure security. Rapid patching of upstream vulnerabilities helps prevent cascading risks across interconnected chains and reinforces trust among developers and institutions relying on Axelar.
Market reaction has been muted but positive, with AXL holding near 0.14 dollars and moderate volume increases. 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.
Axelar Core 1.3.5 update, released December 16, 2025, patches a CometBFT consensus vulnerability affecting multiple Cosmos based chains while fixing a non critical rewards module issue. As a key General Message Passing provider connecting 60+ chains including Ethereum, Polygon, and BNB Axelar’s swift response underscores its role in maintaining secure interoperability amid rising cross chain TVL.
