Orderbook
What is Immutable's Orderbook?​
Immutable Orderbook is a protocol that aggregates and matches buy and sell orders for in-game assets across the Immutable zkEVM ecosystem. It serves as the backbone for peer-to-peer trading, enabling real-time marketplaces that support ERC-721 and ERC-1155 NFTs natively.
Built with flexibility and performance in mind, the Orderbook allows developers to integrate custom storefronts, marketplaces, and in-game trading systems while tapping into a shared liquidity layer. Orders submitted to the Orderbook are accessible across all games and apps on Immutable zkEVM, encouraging a network effect that grows player engagement and asset utility.
Why use Immutable's Orderbook?​
Immutable Orderbook unlocks powerful trading capabilities that let you build dynamic in-game economies without managing the complexities of building and maintaining your own exchange infrastructure. With it, you can offer players real asset ownership and open trading while maintaining full control over how assets are displayed, listed, and consumed in your game.
Key benefits include:
- Shared Liquidity Network: Orders placed in one game or marketplace are discoverable and fulfillable in others, maximizing trade volume and market efficiency.
- Composable and Extensible: Integrate custom trading logic or marketplace UIs while leveraging the underlying Orderbook for robust execution and matching.
- Gasless Trading: Off-chain order creation and matching means players can buy and sell without paying gas, removing friction and boosting engagement.
- Secure and Transparent: Built on a decentralised architecture, Orderbook ensures integrity and fairness in trade execution.
- Optimised for zkEVM: Seamlessly integrates with Immutable zkEVM's ecosystem for faster performance, better user experience, and native support for Ethereum tooling.

High-Performance Order Matching​
Immutable Orderbook is designed for fast, efficient trading. It processes large volumes of transactions with minimal latency, ensuring trades are executed quickly and accurately — critical for in-game economies and real-time digital marketplaces.
Orderbook provides powerful matching capabilities that make your in-game marketplace feel as smooth as traditional Web2 platforms.
Secure and Decentralised Transactions​
By operating on Immutable's zkEVM, Orderbook ensures that all trades are trustless and tamper-proof. There's no need for a centralised exchange — all transactions happen directly between players, backed by blockchain security.
This feature strengthens player trust and protects your game from manipulation or centralized points of failure.
Seamless Integration with Games and Marketplaces​
Orderbook is built to slot into your existing development stack, whether you're building in Unity, Unreal, or using custom infrastructure. Its SDKs and APIs make integration straightforward, so you can launch in-game trading with minimal overhead.
Integration is simple, fast, and flexible — enabling developers to focus on gameplay, not blockchain plumbing.
Cost-Efficient Asset Trading​
Orderbook dramatically reduces the financial barriers to trading, both for players and studios. With optimised on-chain infrastructure and zkEVM's cost savings, you can enable microtransactions and high-frequency trading without punishing gas fees.
Lower costs open new economic models and more accessible gameplay loops.
