Cross-Chain Interoperability Protocol (CCIP)
Chainlink Cross-Chain Interoperability Protocol (CCIP) enables secure, compliant transfer of data and tokens across 60+ public and private blockchains.
Overview
Chainlink Cross-Chain Interoperability Protocol (CCIP) is a blockchain interoperability solution designed to securely move data and value across more than 60 public and private blockchains through a single integration. It enables developers to build cross-chain applications that transfer tokens, arbitrary messages, or both, with built-in compliance and modular security features. CCIP is powered by Chainlink’s decentralized oracle networks (DONs), which have a proven track record securing tens of billions of dollars and facilitating trillions in onchain transaction value. This infrastructure removes single points of failure and provides defense-in-depth security for cross-chain operations.
CCIP supports three core capabilities: arbitrary messaging for sending encoded data between smart contracts on different chains, token transfers for moving assets across chains, and programmable token transfers that combine token movement with instructions for on-chain actions. This flexibility allows developers to orchestrate complex multi-chain workflows, such as cross-chain lending, collateral management, and decentralized finance (DeFi) yield optimization. The protocol supports multiple blockchain families including Ethereum Virtual Machine (EVM) chains, Solana, and Aptos, with tailored account types and integration guides for each.
What sets Chainlink CCIP apart is its modular security framework, which includes multiple decentralized node operators, separation of responsibilities, and a novel risk management network that adapts rapidly to emerging threats. Token developers retain full control over their contracts and token pools, avoiding vendor lock-in and enabling customizable logic. The protocol eliminates reliance on liquidity pools by using burn-and-mint mechanisms, enabling zero-slippage transfers. CCIP also offers compliance tools such as an Automated Compliance Engine and privacy-preserving interoperability, demonstrated in real-world use cases with institutions like ANZ Bank, UBS, and Swift. Developers can get started quickly using comprehensive documentation, SDKs, and tools like the Token Manager and CCIP Explorer.
The Problem
Cross-chain interoperability faces significant challenges including security risks, fragmented liquidity, complex integrations, and compliance difficulties. Developers and institutions struggle to move assets and data securely and efficiently across multiple blockchains without building custom bridges or risking single points of failure.
