Key Highlights
- Nethermind transitions cross-chain infrastructure to Chainlink following comprehensive evaluation.
- The company becomes a Chainlink node operator, providing support for CCIP and Data Feeds.
- Chainlink secures another prominent partner for cross-chain infrastructure services.
- Nethermind discontinues its LayerZero verifier operations to concentrate on CCIP.
- The partnership adds Nethermind’s Ethereum development capabilities to Chainlink’s ecosystem.
Following a thorough infrastructure assessment, Nethermind has transitioned its cross-chain operations from LayerZero to Chainlink. The blockchain technology firm will now run Chainlink nodes that support CCIP and the platform’s established Data Feeds. This strategic shift bolsters Chainlink’s infrastructure capabilities as traditional financial entities increasingly adopt public blockchain technology.
Nethermind Embraces Chainlink for Cross-Chain Services
Under this new partnership, Nethermind assumes dual responsibilities as a Chainlink node operator and strategic technology collaborator. The organization will deliver infrastructure solutions, development resources, and integration assistance for projects constructing blockchain-based applications. Additionally, its cross-chain capabilities will now center around Chainlink’s Cross-Chain Interoperability Protocol, commonly referred to as CCIP.
CCIP enables asset transfers and communication between distinct blockchain ecosystems through Chainlink’s distributed infrastructure framework. The platform employs autonomous node operators alongside risk management mechanisms to oversee cross-chain activity throughout its supported networks. Consequently, Nethermind will leverage its established blockchain development proficiency to enhance infrastructure powering these solutions.
Previously, the firm maintained decentralized verifier infrastructure within LayerZero’s cross-chain communication framework. LayerZero enables applications to choose decentralized verifier networks responsible for validating messages transferred between various blockchains. Nevertheless, Nethermind has terminated its verifier responsibilities and redirected its cross-chain infrastructure efforts toward Chainlink.
Recent Cross-Chain Security Incidents Provide Backdrop
This transition occurs amid notable cross-chain infrastructure developments involving both LayerZero and Chainlink throughout 2026. During April, malicious actors compromised Kelp DAO’s LayerZero-based bridge, extracting approximately $290 million worth of rsETH. The breach involved a fraudulent cross-chain communication and a setup dependent on a singular verifier.
Kelp DAO subsequently migrated rsETH cross-chain infrastructure to Chainlink while contesting LayerZero’s characterization of its security setup. LayerZero disputed these assertions, claiming the project had transitioned from multiple verifiers to a single verifier configuration. Following this, LayerZero implemented more stringent guidelines for applications utilizing its decentralized verifier network framework.
However, Nethermind has not explicitly connected its strategic decision to the Kelp DAO breach or other LayerZero security incidents. The company’s official statement characterized the transition as the outcome of comprehensive evaluation and strategic infrastructure planning. Additionally, Nethermind did not disclose specific technical benchmarks employed when evaluating Chainlink versus LayerZero during this assessment process.
Chainlink Strengthens Position in Cross-Chain Market
Several prominent institutions have similarly shifted their cross-chain operations to Chainlink in recent periods. BitGo designated CCIP as the sole cross-chain infrastructure solution for Wrapped Bitcoin after formerly utilizing LayerZero. Meanwhile, Aave broadened its CCIP implementation to encompass deposits, withdrawals, vault optimization, and additional cross-chain asset operations.
The Wyoming Stable Token Commission finalized another LayerZero-to-Chainlink transition on August 18 following a state-mandated security evaluation. The commission chose CCIP as the exclusive cross-chain provider for its Frontier Stable Token initiative. Nonetheless, Wyoming has not released comprehensive technical conclusions from its infrastructure analysis.
Nethermind contributes substantial Ethereum infrastructure knowledge to Chainlink’s expanding network of independent node operators. Established in 2017, the firm develops an Ethereum execution client while offering security audits, research services, and enterprise blockchain solutions. This new partnership extends those capabilities into oracle infrastructure and cross-chain platforms facilitating institutional blockchain integration.
