Metamask: Mint preproduced tokenurl(file size in range 42:50 Kb) , using svg to store full metadata on chain , Erc-721 , polygon (test & main network)

I can help you with a draft article about Metamask and its uses. Please note that I will be providing a general overview and will not be implementing any code. Here is a starting point:

Draft Article

Introduction

In recent years, blockchain technology has become increasingly popular for various use cases, such as decentralized finance (DeFi), non-fungible tokens (NFTs), and others. One of the most promising platforms in this space is Metamask, a popular wallet solution that allows users to manage their cryptocurrency assets across multiple blockchains.

System Overview

In this article, we will focus on one specific use case: NFT mining using Erc-721 and Polygon (testnet). Our goal is to show you how to prepare an NFT metadata file, saved in a Metamask-compatible format, for deployment on the Ethereum network.

Configurations and Version

Before we dive into the implementation details, it is important to understand the system configurations:

• System: This refers to the underlying blockchain platform (Ethereum) and its version.

• Version: This indicates the specific Erc-721 version being used.

• Overall Idea of the Smart Contract: This is the overall idea of our project. In this case, we will be minting NFTs on Ethereum using Erc-721.

Main Problem

One of the main challenges when working with Metamask and its compatible NFT metadata format is ensuring that the file size fits within a certain range (42 KB to 50 KB). This can cause issues during upload or transfer, especially if the file size exceeds the allowed range. To solve this problem, we will need to optimize the implementation.

Implementation Optimization

To address the issue of large file sizes, consider several optimization strategies:

• Use a more efficient data structure. Instead of storing metadata in an array or object, which can lead to larger file sizes, we can use a binary format such as JSON (JavaScript Object Notation) or MessagePack, which are optimized for compactness.

• Reduce unnecessary fields: Analyze the Erc-721 schema to identify any redundant or unused fields that do not contribute to the overall value of the metadata. This will help reduce the size of our file without losing any necessary information.

Conclusion

In this article, we have explored the general configurations and requirements for NFT mining using Metamask on Polygon (testnet). We have also identified a potential issue with large file sizes that needs to be optimized to ensure compatibility with Metamask’s upload and transfer processes. By implementing these strategies, we can improve the efficiency of the implementation and make it more suitable for production environments.
