A problem faced within the Ethereum blockchain as well as Layer 2s is the segmentation of assets, especially NFTs. When an NFT is created on a Layer 2, the NFT is stuck on that layer. This leads to the problem of NFT silos, where NFT assets on Layer 2 cannot be withdrawn to Layer 1. Having a way to create and transfer NFTs across multiple layers is important in order to introduce NFT applications to Layer 2s.
Create a way to easily transfer NFTs across layers and reduce the gas requirements by minting the NFTs on Layer 2. This lets the user decide when they would like to withdraw their NFTs to Layer 1.
Range is a unit of 1000 NFTs… rangeid 0 means NFT #0 to NFT #999.
Using a rollup to track the chain ownership to reduce the transaction cost
A rollup can be used to manage the chain ownership. In this way, the transaction cost can be greatly reduced. Layer 1 in this case can be treated the same as other rollups to some extent.
The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.
A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!
Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
