Axelar

Axelar is the leading interoperability solution for moving assets and arbitrary messages from one blockchain to another. A pioneer in the bridging of assets, they were the first in the field to implement a broadly deployed bridge that does not rely on a fixed committee or federation, unlike typical multisig bridges. Instead, they rely only on their underlying proof-of-stake security assumptions, by leveraging their population of Cosmos validators. Axelar’s architecture is distinguished by its permissionless proof-of-stake network and hub-and-spoke model, which enables firewalling between connected chains and limits systemic risk in the event of individual chain failures. Among interoperability protocols, Axelar uniquely combines a fully decentralized validator set with real economic value secured on-chain.
Common Prefix has worked closely with Axelar since 2021, beginning before the launch of its public network. Over the years, this collaboration deepened from early security audits of Axelar’s Gateway smart contracts to becoming a core technical contributor to the ecosystem, including the development of complex cross-chain integrations such as the Axelar Amplifier integration with Ripple's XRP Ledger. In late 2025, Common Prefix assumed the lead stewardship role for the Axelar Network, taking responsibility for its technology direction, product evolution, and long-term vision. As part of this role, we are driving Axelar’s 2026 roadmap with a strong focus on institutional readiness, increased economic security, and reducing friction in cross-chain asset transfers. More details on the roadmap and upcoming initiatives are outlined in our blog post, The New Era of Axelar: 2026 Roadmap.

Axelar Amplifier integration with XRPL

Common Prefix has partnered with Axelar to integrate Ripple's XRP Ledger (XRPL) with Axelar's Amplifier interoperability infrastructure. This integration enables bridging assets between XRPL and all Axelar-supported chains. It also allows smart contracts on on other chains to be called directly from XRPL.

Ethereum Light Client on Axelar implementation

Common Prefix collaborated with Axelar to develop a light client that employs Ethereum's Sync Committee protocol to bridge events from Ethereum to Axelar.

Axelar Gateway audit

The Axelar Gateway Solidity smart contract is deployed to every Axelar-supported EVM chain, enabling communication between the Axelar network and the connected chain. Common Prefix was commissioned to audit two versions of the Gateway smart contract (v1 and v2.1).
