Immutable, a web3 gaming platform, announced today that it is commencing public testing of a new layer-2 blockchain, Immutable zkEVM, in a bid to reduce dependence on a single network infrastructure.

The zkEVM is a zero-knowledge (ZK) rollup, a scaling feature aimed at reducing gas fees and increasing transactions, that is compatible with the Ethereum Virtual Machine. This means that developers who are looking to build web3 games can migrate their existing smart contracts from Ethereum to Immutable’s zkEVM testnet without any hiccups.

Immutable’s zkEVM is built with Polygon’s Supernets, a program designed to make it easier for developers to spin up new application-specific blockchains.

This will go live in addition to Immutable X, a so-called validium built with StarkNet, which according to the website L2Beat ranks as the seventh-largest layer-2 project.

“Our goal is to provide game developers with optionality and flexibility in order to decrease the risk of committing to one infrastructure partner,” said a spokesperson with Immutable in an email to CoinDesk.
