Immutable zkEVM Marketplace: gaming's dominant NFT chain, cleared by the SEC and still chasing a proven sector.
We're closing out this round of our NFT Marketplaces series with Immutable, an Australian company founded in 2018 (originally as Fuel Games) by James Ferguson, Robbie Ferguson, and Alex Connolly, purpose-built as a zero-knowledge rollup specifically for NFT minting and trading in Web3 games. Real, disclosed genuine strengths: no confirmed direct hack of Immutable's own zkEVM or X infrastructure found in our research, sub-$0.01-to-a-few-cents transaction fees, ecosystem-level royalty protection for in-game NFTs, and a clean regulatory outcome, the SEC closed its investigation into Immutable's 2021 IMX token sale in March 2025 without any enforcement action. Real, disclosed major 2026 architecture change: Immutable X and zkEVM, previously two separate chains that split liquidity, merged into a single, unified, EVM-compatible chain. What we don't think should be set aside: a real, disclosed pattern of phishing attacks targeting Immutable's own users during ecosystem hype spikes, wallets created within 30 days of being compromised accounted for 58% of all thefts in one measured period, disproportionately hitting new users drawn in by the platform's rapidly growing game library. We weighted all of it below.
Our take, up front: Immutable is an Australian company founded in 2018, originally as Fuel Games, by James Ferguson, Robbie Ferguson, and Alex Connolly, rebranding to Immutable in 2019. Its infrastructure, Immutable X (a StarkWare-powered zk-rollup launched 2021) and Immutable zkEVM (a full EVM-compatible rollup launched 2024), was purpose-built specifically for NFT minting, trading, and in-game asset transfers in Web3 games, a real, deliberate specialization distinct from general-purpose Layer 2s. Real, disclosed major 2026 architecture change: Immutable X and zkEVM, which had previously split liquidity and confused asset location across two separate chains, merged into a single, unified, EVM-compatible Immutable Chain, simplifying developer onboarding and concentrating activity. Real, disclosed genuinely strong technical performance: sub-$0.01-to-a-few-cent transaction fees, roughly two-second block times, and sustained throughput above 100 TPS. Real, disclosed thoughtful onboarding design: Immutable Passport provides frictionless wallet and SSO login specifically for gamers unfamiliar with crypto wallets, alongside gas sponsorship letting game studios cover transaction costs entirely. Real, disclosed usage-linked tokenomics: with 97% of IMX supply circulating by 2025, staking rewards now come directly from 2% of protocol trading fees on a biweekly cycle, a structurally healthier design than the pure-emission reward models that produced wash trading elsewhere in this series. Real, disclosed clean regulatory resolution: after receiving an SEC Wells Notice in October 2024 over its 2021 IMX token sale (a roughly $320 million presale that also drew scrutiny over a disclosed pre-launch investment from Huobi Ventures), the SEC closed its investigation in March 2025 without taking any enforcement action, explicitly finding no violations, though we note this occurred amid a broader SEC retreat that also cleared Coinbase, Kraken, ConsenSys, and Ripple around the same period. Real, disclosed historical footnote: GameStop, an early NFT-marketplace partner, dumped roughly $47 million in IMX tokens in 2022 after winding down its own use of the network. What we don't think should be set aside: a real, disclosed pattern of phishing attacks specifically targeting Immutable's own users during ecosystem hype moments, fake "celebration airdrop" pages spiked measurably in the week following the SEC resolution, and wallets created within 30 days of being compromised accounted for 58% of all thefts in one measured period, disproportionately affecting new users drawn in by a game library and weekly NFT buyer count that had grown 64% to 4,193 unique buyers. No confirmed direct hack of Immutable's own zkEVM or X infrastructure was found in our research. We weighted all of it below.
No confirmed direct hack of Immutable's own zkEVM or X infrastructure found in our research, a genuine positive for foundational gaming infrastructure handling real economic value. Real, disclosed named, long-standing founders (James Ferguson, Robbie Ferguson, Alex Connolly) since 2018. Real, disclosed clean regulatory outcome: the SEC closed its investigation into IMX's 2021 token sale in March 2025 without enforcement action, explicitly finding no violations, though this occurred amid a broader SEC retreat that also cleared several other major platforms around the same period. What tempers this: a real, disclosed pattern of phishing attacks targeting Immutable's own users during ecosystem hype spikes, with wallets under 30 days old accounting for 58% of all thefts in one measured period.
Pros
- No confirmed direct hack of Immutable's own infrastructure since 2018
- SEC investigation closed in March 2025 with no violations found
Cons
- New-user wallets accounted for 58% of phishing thefts in one measured period
- Phishing activity spiked measurably around ecosystem hype moments
Real, disclosed genuine specialization advantage: widely described as the dominant Layer-2 blockchain for NFT gaming, with real, disclosed growth signals (weekly unique NFT buyers up 64% to 4,193 in one measured period). What tempers this: real, disclosed acknowledgment that IMX's price and ecosystem activity remain volatile, tracking the broader, still-unproven Web3 gaming cycle closely, and a real, disclosed historical negative signal, GameStop's ~$47M IMX dump in 2022 following the wind-down of its own NFT marketplace partnership.
Pros
- Widely described as the dominant NFT gaming L2; real, disclosed buyer growth
Cons
- Volume and price remain tightly coupled to an unproven broader gaming cycle
- GameStop's 2022 IMX dump remains a real, disclosed historical warning sign
Real, disclosed named, long-standing founders since 2018, with credible, public-facing leadership throughout the SEC investigation. Real, disclosed functioning IMX governance and staking model, with 97% of supply circulating (minimizing dilution risk) and rewards now tied directly to actual protocol usage (2% of trading fees, distributed biweekly) rather than pure token emissions.
Pros
- Named, credible founders since 2018; public throughout regulatory scrutiny
- Staking rewards tied to actual protocol usage, not pure emissions
Cons
- Governance remains substantially company-directed rather than fully decentralized
Real, disclosed major 2026 consolidation: Immutable X and zkEVM merged into a single, unified, EVM-compatible chain, simplifying what had been a split-liquidity, two-chain structure. Real, disclosed genuinely broad game-studio integration, with the network purpose-built to support many third-party game titles' in-game asset marketplaces.
Pros
- 2026 merger unified previously split liquidity into one chain
- Broad integration across many third-party game titles
Cons
- Narrower focus specifically on gaming NFTs versus general-purpose marketplaces
Real, disclosed genuinely thoughtful, distinctive onboarding design: Immutable Passport provides a frictionless wallet and SSO login specifically built for mainstream gamers unfamiliar with crypto wallets, alongside gas sponsorship letting game studios cover transaction costs entirely. What tempers this: the real, disclosed phishing pattern specifically targeting new users during hype spikes suggests onboarding ease hasn't yet been matched by equivalent security education.
Pros
- Immutable Passport lowers onboarding friction for non-crypto-native gamers
- Gas sponsorship lets studios cover transaction costs entirely
Cons
- New users remain disproportionately exposed to phishing during hype moments
Real, disclosed genuinely strong fee structure: sub-$0.01-to-a-few-cent typical transaction fees, with Immutable X historically offering zero gas fees for core NFT actions specifically. Real, disclosed "ecosystem-level royalty protection" for in-game NFTs, a real, disclosed creator-protective design choice.
Pros
- Sub-$0.01-to-a-few-cent fees; historically zero gas for core NFT actions
- Ecosystem-level royalty protection for in-game assets
Cons
- The zkEVM side of the newly merged chain introduces small gas costs versus X's zero-gas model
Real, disclosed genuinely distinctive gaming-specific infrastructure: a global order book and liquidity network shared across integrated games, gas-sponsored transactions, and embedded wallet support via Immutable Passport.
Pros
- A shared global order book and liquidity network across integrated games
Cons
- Features are tailored specifically to gaming, less relevant outside that vertical
Access only through Immutable's official Passport or partner game clients, and treat airdrop hype as a phishing signal.
Given the real, disclosed spike in fake "celebration airdrop" pages around ecosystem hype moments, treat any unsolicited airdrop-claim link as suspicious by default, verify announcements only through Immutable's own official channels, and be especially cautious in the first 30 days after creating a new wallet.
A genuinely well-run, cleanly-regulated bet on a sector that still has to prove itself.
We want to give Immutable real credit for two things that don't always go together in this industry: a clean confirmed-incident record for infrastructure that's been live since 2018, and a regulatory outcome where the SEC actually looked closely at the company's original token sale and walked away finding nothing to act on. That's a meaningfully stronger result than a settlement or a quietly dropped case, and we think it deserves to be read as such. The technical execution backs it up: sub-cent fees, a sensible 2026 consolidation of what had been two competing chains, and a usage-linked staking model that doesn't repeat the wash-trading incentive mistakes we found elsewhere in this series. What keeps this from scoring higher isn't anything Immutable did wrong directly. It's that the entire thesis still depends on Web3 gaming actually becoming a mainstream habit, and the same onboarding friction Immutable worked hard to remove for legitimate users has also made new wallets a disproportionate target for phishing. Immutable has built genuinely solid infrastructure for a sector that hasn't yet proven it has the players to fill it.
The scorecard above is deliberately general. Whether Immutable is right for you depends heavily on which of these you already are.
The gamer or studio who wants low-fee, high-throughput infrastructure purpose-built for in-game NFT assets
This is exactly where Immutable's genuinely strong technical specialization delivers real, demonstrated value.
The new user who treats any unsolicited airdrop-claim link as suspicious by default, especially in a wallet's first 30 days
Given the real, disclosed phishing pattern targeting new wallets during hype spikes, this habit genuinely matters here.
The IMX holder who values a usage-linked staking model over a pure emissions-based rewards structure
This is a genuine, disclosed structural strength relative to the wash-trading incentive problems found elsewhere in this series.
Anyone seeking a general-purpose NFT marketplace outside gaming
OpenSea and Rarible, both reviewed earlier in this series, are built more directly around broad, cross-category collecting.
The scorecard covers the headline judgment calls. These four tables cover the specifics we didn't want to bury in prose; the SEC investigation timelined precisely, the X-to-zkEVM merger explained, the phishing pattern data, and how IMX's tokenomics compare to emission-based models elsewhere in this series.
The SEC investigation, timelined
| Date | What happened |
|---|---|
| 2021 | Immutable raises roughly $320M in an IMX presale, with over 14% of supply going to the public |
| Oct 2024 | The SEC issues a Wells Notice, probing alleged securities violations tied to the 2021 sale and a disclosed pre-launch Huobi Ventures investment |
| Immutable's response | Publicly calls the action "overreach" and states it is prepared to defend itself in court |
| Mar 2025 | The SEC closes its investigation without enforcement action, explicitly finding no violations |
| Context | The closure came amid a broader SEC retreat that also cleared Coinbase, Kraken, ConsenSys, and Ripple around the same period |
A closed investigation with no violations found is a meaningfully stronger outcome than a settlement or guilty plea, though the broader enforcement-climate shift is real context worth including rather than crediting the outcome to Immutable's conduct alone.
The X-to-zkEVM merger, explained
| Immutable X (2021) | Immutable zkEVM (2024) | Unified Chain (2026) | |
|---|---|---|---|
| Technology | StarkEx zk-rollup | Full EVM-compatible zk-rollup | Single EVM-compatible chain |
| Gas for core NFT actions | Zero | Small (IMX-denominated) | IMX-denominated |
| Problem solved | N/A | Smart-contract flexibility | Ends split liquidity and asset-location confusion |
Running two separate chains had forced game studios to choose between them, splitting liquidity; the 2026 merger is a real, disclosed simplification rather than an abandonment of either technology.
The phishing pattern, by the numbers
| Finding | Detail |
|---|---|
| New-wallet risk | Wallets created within 30 days of compromise accounted for 58% of all thefts |
| Timing pattern | Loss events increased within 24 hours of high-impact IMX news, including airdrop announcements |
| Specific spike | Fake "celebration airdrop" phishing pages rose measurably the week after the SEC investigation closed (Mar 18) |
| Growth context | Weekly unique NFT buyers grew 64% to 4,193 in the same period, expanding the pool of inexperienced targets |
This is a real, disclosed pattern of attackers exploiting genuine ecosystem growth and hype cycles, not a flaw in Immutable's own contracts; the practical takeaway is that new users specifically need clear, proactive security guidance during exactly these moments.
IMX's tokenomics vs. emission-based models elsewhere in this series
| IMX | LOOKS (LooksRare, historical) | |
|---|---|---|
| Reward source | 2% of actual protocol trading fees | Emissions proportional to trading volume |
| Incentive risk | Rewards scale with real usage, not raw volume | Created a direct incentive for wash trading |
| Supply status | 97% circulating by 2025, minimizing dilution | Ongoing emissions tied to trading activity |
Tying rewards to actual fee revenue rather than raw volume removes the direct, mathematical incentive for wash trading that we found was a defining, confirmed problem for LooksRare earlier in this series.
We don't just want to hand you our number; we want to show you how it sits next to what other review desks and comparison sites have published. We're flagging directly that most sources we found focus on IMX as a token investment rather than weighting the phishing-pattern data or the sector-wide volatility as heavily as our methodology does.
Our score lands closely aligned with the aggregated industry average; most sources we found independently credit the same clean regulatory outcome and strong technical execution we weighted, while also acknowledging the same real sector-wide volatility.

No, as of early 2026. The two previously separate chains merged into a single, unified, EVM-compatible Immutable Chain, ending the split liquidity and asset-location confusion that came from running two networks.
No. The SEC issued a Wells Notice in October 2024 over Immutable's 2021 IMX token sale, but closed the investigation in March 2025 without taking enforcement action, explicitly finding no violations.
No confirmed direct hack of Immutable's own zkEVM or X infrastructure was found in our research. A real, disclosed phishing pattern has targeted individual users, particularly new wallets, but this reflects social-engineering attacks rather than a platform vulnerability.
Typical transaction fees range from sub-$0.01 to a few cents. Immutable X historically offered zero gas fees for core NFT actions specifically, while zkEVM introduces small gas costs for broader smart-contract execution.
A frictionless wallet and SSO login system designed specifically to lower onboarding friction for mainstream gamers who aren't familiar with crypto wallets.
James Ferguson, Robbie Ferguson, and Alex Connolly founded the company in 2018 as Fuel Games, rebranding to Immutable in 2019.
GameStop's NFT marketplace used Immutable X's Layer 2 to process transactions. When that partnership wound down, GameStop dumped roughly $47 million in IMX tokens in 2022, a real, disclosed negative historical signal.
Staking rewards come from 2% of actual protocol trading fees, distributed biweekly, rather than pure token emissions, tying rewards directly to real platform usage.
