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.
