README

This package helps the management of a NFT collection. Given that you already generated a (generative) NFT collection with images and metadata, you can use this tool to perform additional operations, such as obfuscation (for partial revealing), update metadata and traits, and others.

Installation

The preferred method of installation is via Composer. Run the following command to install the package and add it as a requirement to your project's composer.json:

composer require inmarelibero/nft-manager

Operations

In a single PHP script you can define one or more steps that will be processed sequentially and independently.

For example, you can:

1. obfuscate metadata leaving the first 100 NFTs in clear
2. then update the "name" metadata with the format My super NFT #{id}
3. and finally format the metadata to have a standard format

You can choose to apply an Operation only to a subset of NFTs, by using the from_id.

Available operations are:

1) Update Metadata

Useful to update the metadata of every NFT, including:

• update attributes
• remove attributes
• remove metadata by key
• update url of the "image" metadata
• update external_url
• update name

2) Format Metadata

Run a standard formatter that:

• order metadata by importante
• order attributes alphabetically

3) Obfuscation

Lets you replace the attributes with a placeholder (eg. "?") to obfuscate traits.

Useful when doing partial revealings, because you can specify a starting ID to obfuscate from.

4) Renumbering

Used when:

• your NFTs start from 0 and you want to renumber them starting from 1
• there are holes in your collection

5) Shuffle

Shuffle the entire collection randomly.

Usage

• start from an empty folder, eg. mkdir my_project
• enter the folder: cd my_project
• install this package: composer require inmarelibero/nft-manager
• create folder my_project/input with the following subfolders:
  • input/
    • images/ <- put all the NFT images here
    • metadata/ <- put all the NFT metadata here
• create a php file eg. /run.php (see section Run script for the content)
• run script: php run.php
• in the /output folder you will find the resulting collection

Run script

You must create one PHP script, defining the list of Operations that will be applied sequentially to your input NFT collection.
