Chainlink CCIP - Cross-Chain Interoperability Protocol
Build with CCIP
CCIP makes it simple to move data, messages, and tokens across blockchains. Connect smart contracts on different networks as if they were one system, whether transferring stablecoins, powering cross-chain apps, or running multi-chain DeFi.
Deploy/enable a token across multiple chains
Create a new Cross-Chain-Token or enable an established one that can be launched on 50+ chains, providing unparalleled interoperability and reach.
Bridge a token
Securely transfer tokens - including ETH, USDC, LINK - and messages between different blockchain networks.
Send a token with data
Build token transfers that do more than move value, letting you embed business logic directly into your cross-chain workflows.
Tutorials

Given the inherent risks of cross-chain interoperability, CCIP features defense-in-depth security and is powered by Chainlink's industry-standard oracle networks which have a proven track record of securing tens of billions of dollars and enabling over $14 trillion in onchain transaction value.
CCIP's robust security framework is built upon several core components:
- Proven Decentralized Architecture: CCIP leverages the same highly reliable infrastructure as Chainlink Data Feeds, which has enabled trillions in transaction value across hundreds of DeFi applications. Cross-chain transactions are validated by multiple decentralized oracle networks (DONs).
- Rate Limiting: To mitigate risk, CCIP includes a rate limiting feature. This allows owners to establish and configure policies for Cross-Chain Tokens, which are then enforced on both the source and destination chains.
- Timelocked Upgrades: All on-chain, security-critical configuration changes and core infrastructure upgrades must pass through a Role-based Access Control Timelock contract. This process provides a review period during which CCIP node operators can veto the upgrade, or, in time-sensitive situations, explicitly approve it.
- High-Quality, Sybil-Resistant Node Operators: The system is secured by the same globally distributed, security-reviewed, public node operators that secure other Chainlink services, validate leading blockchain networks, and operate traditional Web2 infrastructure. Each independent CCIP node is run by a distinct organization with extensive DevOps expertise and rigorous private key management security practices.
