Interoperability is one of the key value propositions of Polkadot. With XCM and numerous bridges this value became possible. But they are all delivering interoperability only for fungible assets. For Polkadot to fully deliver on its promise, NFT XCM capability is a must have. Moving NFTs between different parachains will unleash the capabilities for the next generation of Web3 applications that are not constrained by any one chain.
Since January 2023 we (Unique Network team) worked on the NFT XCM solution. We engaged with numerous ecosystem members &mdash; Parity XCM team, Parity NFTs creators, parachains and wallets to create a solution PoC and its roadmap as described in this <a title="NFT XCM Proposal" href="https://docs.google.com/document/d/1ZE2NAsk5ECPRFdn5wOXBpHeXwK29CYsNPR2Qk3RRnPE/edit?usp=sharing" target="_blank" rel="noopener" target="_blank" rel="noopener">proposal.</a>&nbsp;
. Roadmap implementation will require a consensus on a number of questions, which will help establish the NFT XCM standards, and here views and participation of parachains is crucial. Parity has left us to lead this effort, and we would like to invite other stakeholders to take part, too. In the initial stages of the work we will be creating a working group for participants to communicate and collectively decide on key decisions.&nbsp; This proposal follows the successful implementation of the PoC, as described in the Milestone 1 of the proposal which was completed on December 20, 2023 after a year of work. 
Please read the <a title="NFT XCM Proposal" href="https://docs.google.com/document/d/1ZE2NAsk5ECPRFdn5wOXBpHeXwK29CYsNPR2Qk3RRnPE/edit?usp=sharing" target="_blank" rel="noopener">proposal </a>. Happy to answer any questions.
Update: a note for Core devs - the solution does not need any changes to the relay, and is very light on the parachains, too. Brian (Acala) can attest to that. Here are details on the PoC: https://docs.google.com/document/d/1Y90tldtdh9mX1BkUNKDePiV8GImhGSnjaJkk5U54d-w/edit?usp=sharing

Update: important feature of the proposal to underscore - it will be built by multiple teams. The funds for EVM, Ink!, use case bounty and educational materials are dedicated to external teams, since XCM has to work for all parachains it only makes sense that multiple teams are involved.

We invite all interested ecosystem members to comment, provide input and indicate interest in participating in the roadmap. We are soliticing inputs now, to include in the final proposal that will be submitted to Polkadot Treasury after the completion of the PoC in October or November 2023.

Our team will also answer your questions here. Proposal will be presented at Sub0 next week, you can also talk to our lead dev about it there.

NFT XCM

Problem Statement:
- The current interoperability solutions in Polkadot only support fungible assets, leaving a gap in the ability to transfer non-fungible tokens (NFTs) between parachains.

Significance:
- Enabling NFT XCM capability in Polkadot will unlock the potential for next-generation Web3 applications that are not limited to a single chain.

Proposed Solution:
- The Unique Network team has developed a proof of concept (PoC) and roadmap for NFT XCM, and is seeking consensus and participation from other stakeholders, including parachains, to establish NFT XCM standards.

Expected Outcomes:
- Successful implementation of the NFT XCM solution will allow for the seamless transfer of NFTs between different parachains in Polkadot, enhancing the overall interoperability of the network.
