1.Regarding token engineering, firstly, NFTs are also a type of token. Our product is a solution to improve NFT liquidity, which is indeed a valuable research area in token engineering.

2.The core of our product is a cross-chain NFT trading marketplace. Researching cross-chain transactions for NFTs is an innovation that holds significant value for cross-chain research in token engineering.

3.Our product includes a point token, which is a non-transferable ERC20 token. We believe that this token holds great value for the project's development, as its non-transferability reduces risks.

4.Evaluating whether we have achieved our goals: If our product can maintain a specific user experience and usage over the long term, it indicates the feasibility of our token engineering design. This, in turn, has value as a reference for overall token engineering practices.
