Looks great! just a few small comments but I'm definitely on-board. 👍

I think for advanced use cases "Router Passthrough" method is much better.

[sisyphusSmiling]

@bluesign I can see an eventual future where that's supported. As proposed, the changes are an iterative step in that direction.

What do you think about the proposed design? Or are you suggesting the "router passthrough" alternative should be pursued instead?

[bluesign]

No I think current proposal is also very good, but maybe later we can also consider passthrough

Update: Added a draft PR to flow-nft defining the proposed views outlined in this FLIP. Feel free to leave feedback specific to how those are implemented on that PR.

Update: Base solidity contracts required for Cadence-native NFTs have been implemented, approved and merged - onflow/flow-evm-bridge#168

@sisyphusSmiling is there any partner already working or planning to work with new standard?

seeing some real code and use cases can be valuable at this stage imo. For me personally code is much easier to grasp than text, I mean FLIP is pretty detailed and well written, but real world usage can give some new ideas.

@bluesign you can see an example of a WIP implementation here - dapperlabs/nba-smart-contracts#281

[sisyphusSmiling]

Given all feedback thus far has been positive, I've marked the FLIP as approved and will merge shortly. However, please feel free to chime in with any feedback or questions as implementation continues.
