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 CCIP Directory. For more detailed information about the Lock and Unlock mechanism and its applications, read the Token Pools page.

The LINK equivalent of the fee is calculated at request time, and then deducted from your subscription in LINK at response time. See the example cost calculation for more information.
