Immutable zkEVM is a gaming chain built on Ethereum that allows game developers to introduce customised digital ownership and Web3 mechanics in their games.

💡Technical Configurations
Immutable zkEVM Mainnet is now in Early Access. This means you can start to migrate your Testnet project to Mainnet.
  • If you want to access our technical configurations quickly such as endpoints including Mainnet, you can go directly here.
  • If you need help with migration to Immutable zkEVM, you can read our guide here.
  • Please ensure all collections utilise Immutable's operator allowlist to protect royalties and protocol fees.

What is a zkEVM?

The EVM (Ethereum virtual machine) is the virtual machine that enables smart contracts to be executed on the Ethereum blockchain. Immutables zkEVM is a variant of the EVM built on Layer 2 zk-rollup, which is a scaling solution that enables high throughput and low-cost transactions while leveraging the security of the Ethereum mainnet.

The core benefit that it provides developers is that they can now build applications on a secure Layer 2 solution using the same language (Solidity) and development frameworks that they are used to on Ethereum Layer 1.

Immutable zkEVM or Immutable X?

Immutable offer two different rollup technologies on which you can build your Web3 game: Immutable X (built on StarkEx) and Immutable zkEVM (built on Polygon zkEVM).

💡Use a single rollup
We recommend selecting one rollup to minimise developer and player friction that can be experienced by cross-rollup games.

Which rollup is right for your game? See the comparison table below:
