Chainlink’s Cross-Chain Interoperability Protocol has been deployed to Neo X on MainNet, giving the EVM-compatible chain access to one of the most widely used cross-chain messaging and token transfer systems in the blockchain industry. The integration was included in a blockchain expansion update published by Chainlink on May 22.
The deployment is the second major external interoperability protocol to go live on Neo X following LayerZero’s MainNet integration in April, and adds to the native Message Bridge connecting Neo X and Neo N3. Neo X now has three cross-chain pathways available to developers and users.
What CCIP enables
CCIP provides three core capabilities for connected chains. Arbitrary messaging allows smart contracts on different blockchains to send encoded data and trigger actions on each other. Token transfers enable assets to move between chains directly. Programmable token transfers combine both, moving assets and instructions in a single cross-chain transaction, allowing a transfer to carry execution logic to the destination chain.
CCIP is built on Chainlink’s decentralized oracle infrastructure, currently supports connections across more than 70 blockchains, and processed over US $18 billion in cross-chain transfer volume in Q1 2026.
Chainlink’s documentation confirms a dedicated Neo X MainNet CCIP configuration page listing contract addresses, a chain selector, and fee token support for LINK, WGAS, and native GAS. A TestNet configuration is also available. The directory currently shows a single active lane between Neo X and Ethereum, with no tokens configured for cross-chain transfer yet, meaning arbitrary messaging is available but token transfers are not yet operational.
