Immutable zkEVM vs Soon: Which chain fits? (2026)

The central difference is the execution environment. Immutable zkEVM is EVM-compatible, so developers can use familiar Ethereum tools and smart contract languages. Its stated focus is games, including on-chain assets and economies, and the wider Immutable platform describes tools for player identity, engagement campaigns, attribution and game launches.

Soon takes a different route: it runs the Solana Virtual Machine rather than the EVM. It is built on the OP Stack and settles to Ethereum, making it an Ethereum-linked rollup for teams that want SVM execution. Soon also describes its SVM as decoupled from the underlying Solana network design and aims for compatibility with other Layer 1 blockchains, though details of that compatibility are not published.

In practice, the first question is which environment your application needs. Immutable’s gaming focus and EVM compatibility make its use case easier to identify; Soon is more specifically suited to projects targeting SVM execution.

Neither project publishes specific transaction fees or bridging costs. Immutable describes its chain as low cost, but does not give gas figures. Its studio tools also have no published pricing. Soon calls its rollup stack efficient, but does not provide gas or bridge-cost figures either.

That means there is no reliable published basis to say which will cost less for a particular transaction or application. Costs can also depend on activity and on moving assets between Ethereum and the chain. Soon’s fee information notes that bridging to a rollup involves Ethereum gas costs; Immutable’s fee information likewise leaves its bridge costs unstated.

Before choosing, check the current transaction prompt and the project’s official documentation for applicable costs. For a game or application with frequent small transactions, test the actual expected flow and transaction types before committing. Do not treat descriptions such as “low cost” or “efficient” as a substitute for published fee schedules or observed costs.

Neither project has audits listed. Immutable describes its chain as offering Ethereum security, but its published security information does not list audits or an incident history. Soon also has no audits listed, and its public security details do not describe sequencer setup, upgrade keys, bug bounty coverage or security contacts.

Both designs involve risks beyond ordinary wallet use. Smart contracts and bridges can contain vulnerabilities, and users can face phishing risks. Soon’s rollup design also raises questions about sequencer centralization and upgrade keys, while Immutable’s bridging and game contracts have their own risks. Public information does not settle those questions for either chain.

Treat security claims as claims to verify, not as a replacement for technical detail. Before bridging meaningful funds or deploying an application, check the official documentation for current audits, bridge controls, upgrade authority and recovery arrangements. Use official project channels and be cautious with unfamiliar contracts.

Immutable zkEVM has the larger listed TVL: about $23.9 million, compared with Soon’s roughly $440,000. Immutable’s TVL is described as having fallen 9.9% over seven days, while Soon’s small TVL points to limited adoption. These figures are indicators of activity, not proof of safety, future growth or suitability for a particular application.

Immutable also lists an IMX token. Soon lists a SOON token, but its utility is not publicly described. Neither publishes transaction fees, and ease-of-use ratings are not available here, so those factors cannot settle the choice. Immutable’s broader platform includes game-growth tools, though its homepage emphasis on an AI growth platform makes the chain’s current role less clear. Soon’s minimal public detail leaves many technical and operational questions open.

Choose Immutable when EVM compatibility and a game-oriented ecosystem matter most. Choose Soon when SVM execution is a requirement and you are comfortable evaluating an early-stage rollup with limited public detail.
