The Flow team has a tentative plan to deploy a new CrossVMMetadataViews contract to the NonFungibleToken smart contract account on mainnet on Feb 20th, 2025. This is a non-breaking change and will add metadata views that projects can implement to allow custom bridged tokens with the Flow VM bridge. More details about the change below.
The testnet contract is already deployed at Account 0x631e88ae7f1d7c20 | Contract Browser
Assuming that the contract on testnet is tested successfully and there is no other feedback, mainnet deployment will be on Thursday, February 20th.
The changes to these contracts that will be used for the upgrade can be found in this pull request:

The changes are documented in the PR and in the associated FLIP:
The change is backward compatible for all code.
Note - We are open to changing the timeline if the community provides feedback on the suggested change.
Developers are also encouraged to review these changes and offer feedback. They are also encouraged to use these new views in their own NFT smart contracts and apps.
If you have any questions regarding these changes, please ask in the PR comments, on Discord in the #4d-ux-builders channel.
