TEP404 standard and implementation

[kojhliang]

Summary

NotFound Labs team and HowardPeng propose to submit a TEP404 standard to TON Blockchain TEPs and implement the first TEP404 protocol using FunC.

This protocol can increase the liquidity of NFT transactions, implement the fragmentation of NFTs, and facilitate the exchange between different NFTs.
 Our goal is to promote this TEP404 standard, let more native NFT projects support the TEP404 standard, and easily swap NFTs with each other. This proposal contains a TEP404 standard specification document, high-quality FunC codes of TEP404 standard, and Ts test scripts.

Context

Currently, there is no semi-fungible token(SFT) standard and implementation on TON TEPs.We think the semi-fungible token standard is a very important component of the TON ecosystem. And ERC404 protocol is a useful protocol for the semi-fungible token standard. Therefore, we want to implement this protocol on TON to make NFTs flow freely.
 In addition, we will optimize the protocol to address the issue of high gas fees in the original ERC404 protocol.

Thank you very much, guys, for your proposal. I like your TEP404 idea. I suggest we keep in touch and reopen the bounty once the standard is accepted. After that, we can also discuss the rewards, thank you.
