Early Access
Chainlink CCIP is in the “Early Access” stage of development, which means that Chainlink CCIP currently has
functionality which is under development and may be changed in later versions. There is no guarantee any of the
contemplated features of Chainlink CCIP or the Chainlink Network will be implemented as specified. Chainlink CCIP is a
messaging protocol. Chainlink does not hold or transfer any assets. Please review the Chainlink Terms of
Service which provides important information and disclosures. By using Chainlink CCIP, you
expressly acknowledge and agree to accept these terms.
Mainnet Access
Apply for Mainnet Early Access to start
building on mainnet.
Each available network has two rate limits:
Network rate limit: Each network has a limit on the total USD value that can be transferred from one network across all available lanes. CCIP uses Chainlink Data Feeds to calculate the total USD value of tokens transferred on one network.Token rate limits: Each individual lane on a network might have a limit on the total number of tokens that it can transfer. This limit is independent of the USD value of the tokens.
Both limits have a Refill rate , which is the speed at which the maximum capacity is restored. For example, if 100 LINK is transferred using the Ethereum Sepolia => Optimism Goerli Lane, the total capacity for that lane is used up. After that, the maximum capacity restores at a rate of 1 LINK per second.
Read the LINK Token Contracts page to learn where to get testnet LINK and native gas coins. You can pay fees for each network in native gas coins, wrapped native gas coins, or LINK tokens.
Service Limits
Across all networks, CCIP transactions are subject to the following service limits:
Item Description Limit Maximum message data length data payload sent within the CCIP message 50 kilobytes Message Gas Limit User specified gas limit 2,000,000 Maximum number of tokens Maximum number of distinct tokens a user can transfer in a single transaction 5
