Non-Fungible Tokens (NFTs) introduced true digital ownership to gaming, allowing players to own, trade, and monetize their in-game items. However, Web3 gaming initially struggled with Ethereum’s mainnet limitations: high gas fees, network congestion, slow settlement speeds, and complex crypto onboarding.
Immutable (IMX) was built specifically to solve these bottlenecks.
As the premier Layer-2 scaling platform dedicated to Web3 gaming, Immutable provides high-throughput, gas-free NFT minting and trading while retaining Ethereum’s underlying security.
In this comprehensive guide, we explore how Immutable works, the shift to Immutable zkEVM, the friction-reducing power of Immutable Passport, and the utility of the IMX token.
What is Immutable?
Founded by James Ferguson, Robbie Ferguson, and Alex Connolly, Immutable is a specialized Layer-2 scaling engine for Ethereum engineered for AAA Web3 games, NFT marketplaces, and digital collectibles.
Unlike general-purpose Layer-2 networks, Immutable focuses exclusively on the needs of game developers and players:
Zero Gas Fees: Players can mint and trade in-game NFTs without paying transaction gas.
High Throughput: Capable of processing up to 9,000 transactions per second (TPS) with near-instant finality.
Mainstream Gaming UX: Frictionless wallet creation and fiat on-ramps built directly into games.

The Tech Stack: From StarkEx to Immutable zkEVM
Immutable’s technological evolution focuses on delivering maximum performance without sacrificing liquidity or composability.

1. StarkEx Validium (The Original Engine)
Initially built in partnership with StarkWare, Immutable X utilized StarkEx zero-knowledge rollup technology. It batched thousands of off-chain NFT trades into a single validity proof submitted to Ethereum, enabling lightning-fast, zero-gas transactions.
2. Immutable zkEVM
To give game studios full smart contract flexibility, Immutable launched Immutable zkEVM (powered by Polygon). This EVM-compatible environment allows developers to deploy standard Solidity smart contracts, custom crafting mechanics, staking pools, and ERC-1155 token standards.
Unified Ecosystem: To eliminate liquidity fragmentation and streamline player wallet flows, Immutable unified its scaling environments under a single, cohesive chain infrastructure, streamlining wallet management and marketplace liquidity across all titles.
Breaking Barriers to Mainstream Gaming: Key Features
Immutable solves the core user-experience (UX) problems that historically turned traditional gamers away from Web3:
1. Immutable Passport
Creating a Web3 wallet, managing seed phrases, and approving gas popups ruin game immersion. Immutable Passport is a non-custodial, passwordless onboarding system that allows players to create and access a Web3 wallet using familiar Web2 social logins (Google, Apple, or email).
2. Global Shared Liquidity Pool
On standard blockchains, NFT listings are isolated to the specific marketplace where they are created. Immutable uses a Global Order Book. An item listed on one in-game marketplace automatically appears on every other marketplace connected to the network, maximizing liquidity and price discovery for players and creators.
3. Developer-Friendly SDKs
Game studios can integrate blockchain features using simple REST APIs and SDKs without writing complex smart contract code from scratch, dramatically cutting down game development cycles.
Flagship Web3 Games Powered by Immutable
Immutable powers a growing catalog of high-budget Web3 games, including:
Gods Unchained: A popular decentralized trading card game where players truly own their cards.
Guild of Guardians: A mobile Web3 action RPG featuring playable NFT heroes.
Illuvium: An open-world RPG and auto-battler ecosystem built on high-fidelity graphics.
What is the Role of the IMX Token?
The IMX token is an ERC-20 asset that drives governance, staking, and economic alignment across the entire ecosystem:
| Protocol Fee Mechanism | A 2% fee applies to secondary NFT sales across the ecosystem. 20% of this fee must be paid in IMX. If a user pays in another token, Immutable automatically buys IMX on the open market to fulfill the fee. |
| Active Staking Rewards | Users who stake IMX and actively participate in the ecosystem (e.g., liquidity provision or trading) earn a share of protocol fees. |
| Decentralized Governance | IMX holders can vote on protocol upgrades, grant distributions, and ecosystem parameters. |
Benefits & Limitations of Immutable
| Benefits 🚀 | Limitations ⚠️ |
| Gas-Relieved UX: Players can trade and mint NFTs without paying transaction gas fees. | Secondary Sales Royalty/Fee: A 2% protocol fee applies to marketplace trades. |
| Ethereum Security: Leverages zero-knowledge validity proofs back to Layer 1. | Web3 Gaming Adoption: Mainstream adoption depends on AAA game studios delivering genuinely fun gameplay. |
| Frictionless Onboarding: Passport simplifies wallet creation for traditional gamers. | Migration Overhead: Users managing legacy StarkEx assets and zkEVM environments require bridging tools. |
Frequently Asked Questions (FAQ)
Is minting NFTs on Immutable really free?
Yes. Immutable allows gas-free minting and trading for end users. Game developers or marketplaces can sponsor gas or incorporate transaction costs seamlessly.
How does Immutable Passport protect user private keys?
Immutable Passport is a non-custodial solution. It uses threshold cryptography (MPC) to secure keys while allowing players to sign in using familiar Web2 social credentials (like Google or Apple ID) without giving up custody of their assets.
What is the difference between Immutable X and Immutable zkEVM?
Immutable X was the original app-specific rollup built on StarkEx. Immutable zkEVM is an EVM-compatible Layer-2 environment powered by Polygon, allowing developers to write custom smart contracts while sharing unified liquidity and Passport onboarding across the ecosystem.
