Developed by Australia-based Immutable, Immutable X is a decentralized protocol that allows developers to create P2E games and interact with smart contracts. This is accomplished using a layer-2 framework built on top of the existing blockchain.Immutable X is built with a secure platform and an API abstraction layer that allows developers to build games quickly and easily. It also features instant trading and zero fees. This means users can trade ERC-20 tokens at a lower cost.Immutable X is also one of the first platforms to use ZK-rollups, which combine a large number of transactions into one transaction. This solution greatly reduces the storage needed to validate blocks. Immutable X also offers near-zero gas fees.
