Introduction

Immutable X is a cutting-edge protocol for non-fungible tokens (NFTs) on Ethereum, offering a seamless user experience and high scalability. It enables projects to build on Layer 2 Ethereum while leveraging the security and network effects of the Ethereum network. The protocol incorporates several core components to achieve these goals:

ZK-Rollup Scaling Engine

One of the key advantages of Immutable X is the ability to mint assets entirely on Layer 2 (L2) while maintaining the security of Layer 1 (L1). This is made possible through the use of a ZK-Rollup scaling engine.

With Immutable X, every asset can be minted with immutable metadata, known as a "minting blob" or "blueprint". This metadata is passed to the L1 smart contract when the asset is withdrawn. This technology has already been successfully used to mint over 10 million NFTs on Immutable X, surpassing the number of ERC721 NFTs on L1.

In addition to immutable metadata, assets on Immutable X can also have "mutable metadata". This metadata can be updated by polling the minting application's server at regular intervals. To provide a standardized representation of each asset's mutable metadata properties, each application can optionally provide a "metadata schema". This allows NFTs to represent various types of digital assets, such as game assets with changing experience levels or generative artwork NFTs based on an immutable seed and mutable user inputs.

Typescript SDK Implementation

Immutable X offers a Typescript SDK implementation that simplifies the integration of the protocol into websites. This SDK provides typed access to the Immutable X APIs and Wallet, making it platform-agnostic and easy to use for developers. By utilizing the SDK, developers can seamlessly incorporate Immutable X functionality into their applications, enabling instant trading, massive scalability, and zero gas fees for minting and trading NFTs.

Overall, Immutable X is a technically advanced solution for scaling NFTs on Ethereum. It combines the benefits of Layer 2 scalability, instant trading, and zero gas fees with the security and network effects of the Ethereum network. With its ZK-Rollup scaling engine and Typescript SDK implementation, Immutable X offers a fantastic developer and user experience for NFT projects.
