This standard proposes a way to represent NFTs as a single smart contract rather than having a separate smart contract for each NFT.

Implementing batch-minting by handling data storage and processing off-chain to minimize on-chain computational costs and improve overall efficiency.

This standard supports the creation and management of NFTs on the Aptos, enabling unique digital asset creation and management.

We will be using the Solana web3.js Library for implementing the Solana blockchain.

Utilizing the Solana Program Library (SPL) for batch-minting tokens, leveraging its high throughput and low latency to efficiently mint multiple tokens in a single transaction.

Using a Merkle tree to verify the token data's validity can reduce the transaction's gas cost and speed up the batch minting process.

This standard facilitates the creation and management of fungible tokens on the Aptos, allowing for seamless token interactions and transactions.

We can optimize storage services by using efficient data structures and algorithms. By optimizing storage services, we can reduce the time and cost required to access and manipulate data.

This standard enables the creation of composable and hierarchical non-fungible tokens, allowing for the creation of complex digital assets that can be split, combined, and recombined.

To Implement Support for Dynamic and Nested NFTs, we add the following changes to our project:

First, we will create an ERC-721 compliant smart contract. This contract will include the standard functions required by the ERC-721 standard. To support metadata for each NFT, the contract will implement the tokenURI function, which returns a unique URI for each NFT. This URI can point to a JSON file containing metadata such as the NFT's name, description, image, and other properties.

With this basic ERC-721 contract in place, we can proceed to make the necessary changes to support dynamic and nested NFTs:

1) Smart Contracts:

• Add an NftType enum to differentiate between static, dynamic, and nested NFTs.
• Modify the NftData struct to include fields for nftType, parentId, and childIds.
• Adding the createStaticNft function that creates a new static NFT with the specified recipient and token ID.
• Adding the createDynamicNft function that creates a new dynamic NFT with a new token ID and the specified recipient.
• Adding the createNestedNft function that creates a new nested NFT with a new token ID, the specified recipient, and the parent NFT ID. It also adds the child NFT ID to the childIds array of the parent NFT.
• Adding the getChildNfts function that returns an array of child NFT IDs for a given parent NFT ID. (used to retrieve child NFTs for the nested NFTs)

2) Contract Interaction Functions:

• First we will update the deployment functions to include the new NftType enum and NftData struct.
• Then we will modify the minting functions to support dynamic and nested NFTs, accepting parameters for NFT type and parent ID.
• We will also implement new functions for creating dynamic and nested NFTs, interacting with the corresponding smart contract functions.
• At last, we will add a function to retrieve child NFTs of a parent NFT.

3) Collection and Contract Classes:

• We will then update the Collection class to include properties and methods related to dynamic and nested NFTs, such as creating, retrieving, and updating metadata.
• After that the contract class is updated to incorporate the NftType enum and NftData struct, we will update the relevant methods accordingly.
• At last we will handle the Storage and Metadata Management by:
  • Firstly, enhancing the storage classes to handle metadata for dynamic and nested NFTs, including methods for updating and versioning metadata.
  • Secondly, modifying the metadata structure to include fields for NFT type parent ID, and child IDs.

Introducing a refined folder structure that categorizes functionalities based on their respective chains. Specifically, creating separate folders for each chain, where the related contracts and associated functions will reside. At the same time also fixing bugs and updating documentation.

Currently we are supporting NFT.Storage, Pinata, Infura IPFS (temporarily unavailable), Storj, Arweave with our storage classes

We can support additional storage providers such as Helia, web3storage, lighthouse, moralis ipfs, bundlr with the help of web3stash module in the project to provide an option for the users to choose from variety of our services

This would be just an additional small piece of code for every storage provider and would not require any special config than the previous config (PR raised here )

Let me know if this sounds right and i will raise a PR for the same

Feel free to suggest any additional changes

This standard allows for the creation and management of token assets on the Solana blockchain, supporting various use cases including fungible and non-fungible tokens.

Currently, you will find there are storage classes used for uploading metadata through multiple providers. Remove that code and instead use web3Stash https://github.com/mbcse/web3stash Library to upload metadata.

Description:
Presently, our codebase employs storage classes for uploading metadata across various providers. This proposal suggests deprecating the existing storage class implementation and transitioning to the use of the web3Stash library (https://github.com/mbcse/web3stash) for a more streamlined and standardized metadata upload process.

Proposed Changes:

Deprecation of Storage Classes: Remove the existing code that utilizes storage classes for metadata uploads.
Integration of web3Stash Library: Incorporate the web3Stash library into the codebase for a unified and efficient metadata uploading mechanism.

For Aptos, we will be using the Aptos SDK for implementing the Aptos blockchain.

Description

As our project advances towards the integration of additional chains and functionalities, it becomes imperative to enhance the organization of our codebase for improved maintainability and clarity. The proposed solution involves a thorough refactor of the current folder structure, specifically segregating functionalities into distinct folders.

Objective

To establish a more organized and scalable folder structure that accommodates the growing complexity of integrating various chains and functions seamlessly.

Proposed Changes

Introduce a refined folder structure that categorizes functionalities based on their respective chains. Specifically, create separate folders for each chain, where the related contracts and associated functions will reside.

|   |-- contracts/
|   |-- functions/
