Chainlink CCIP is now Generally Available (GA) on mainnet and testnet.
To support your development and implementation needs, we encourage you to reach out to our team of experts for guidance and support. For expert advice, visit the Chainlink CCIP Contact form.
Additionally, the Chainlink CCIP local simulator is available to enhance your development workflow with CCIP. This tool allows you to simulate Chainlink CCIP functionality locally within your Hardhat and Foundry projects. The simulator is designed so you can test your contracts locally and transition smoothly to test networks without any modifications.

The maximum gasLimit that you can set for CCIP messages on mainnet has been increased to 3,000,000 gas units. The change has been documented in the Service Limits page.
Chainlink's CCIP now supports WETH (Wrapped Ether) transfers through the Lock and Unlock token mechanism.
This feature allows CCIP to securely lock tokens on the source blockchain and subsequently release an equivalent amount of tokens on the destination blockchain, facilitating seamless cross-chain transfers of WETH. The introduction of this mechanism enables WETH transfers across several key lanes.
For a specific lane configuration, see the Supported Networks page. For more detailed information about the Lock and Unlock mechanism and its applications, read the Token Pools page.
Chainlink Node v2.10.0 is now available. See the Release Notes for details.
CCIP v1.0.0 is no longer supported on mainnet. You must use the new router addresses listed in the CCIP v1.2.0 configuration page.
