Immutable (IMX)

Immutable (IMX) is the native token of Immutable, an Australian company and network built for blockchain games and the digital items traded in them. IMX pays transaction fees on Immutable Chain, is staked by holders, and is used in the network's governance and reward programmes. Immutable is best known for Gods Unchained, a trading-card game made by its founders, and for the tools it supplies to other studios.

The token is distinct from the networks it has powered. Immutable X, launched in 2021, was a zero-knowledge rollup for NFTs built with StarkWare; Immutable zkEVM, now called Immutable Chain, is a general-purpose chain compatible with the Ethereum Virtual Machine. Both settle to the Ethereum Blockchain. Immutable competes with other gaming networks such as Flow (FLOW) and Ronin, the chain behind Axie Infinity (AXS).

Think of the items in a video game: a rare sword, a character skin, a card. In most games those items live on the publisher's servers, and when you stop playing they are effectively gone. Immutable gives such items a permanent public record, so a player can own them, sell them to someone else, or keep them even if they leave the game.

Recording every trade directly on Ethereum would be slow and expensive, a little like posting each receipt by registered mail. Immutable bundles thousands of trades together and sends Ethereum a single compact proof that they were all valid. IMX is the token used to pay for this service and to reward the people who support the network.

Immutable was founded in Sydney by Robbie Ferguson, James Ferguson and Alex Connolly. The brothers launched Gods Unchained in 2019 and found that Ethereum fees made in-game trading impractical, which led to Immutable X, launched in 2021 using StarkWare's StarkEx technology. The IMX token followed later in 2021, after private sales and a public token sale. In 2023 Immutable announced a zkEVM chain developed with Polygon, opening it to selected studios from late 2023 and more widely in 2024. In early 2026 Immutable X was merged into Immutable Chain: tokens held on it were moved across automatically, and most NFTs were migrated by their games.

Immutable Chain is a layer 2 network that runs Ethereum-style smart contracts, so game studios can use common developer tools. Immutable supplies a shared order book that lets marketplaces list the same items, and Passport, a wallet and login system that lets players sign in with an email address instead of handling a seed phrase. Games can also bridge assets between Immutable Chain and Ethereum. The chain is designed for low and predictable fees, which matters when players make many small trades. Because Immutable X used validity proofs rather than the fraud proofs of an optimistic rollup, withdrawals to Ethereum did not have to wait through a challenge period. Studios that build on Immutable can also set royalties on secondary sales, so a game earns a share each time one of its items is resold between players, a model that conventional app stores do not offer.

IMX has a fixed maximum supply of 2 billion tokens, released over several years to the company, investors, the ecosystem and the community. It has several uses:

• Fees. IMX is the gas token that pays for transactions on Immutable Chain.
• Staking. Holders can stake IMX to earn a share of network rewards; see staking.
• Rewards. Immutable has run programmes that reward players, studios and stakers in IMX for activity on the network.
• Governance. IMX is intended to give holders a say over network decisions.

Scheduled releases of locked tokens, known as token unlocks, add to the circulating supply and are watched closely by traders.

In November 2024 Immutable disclosed that it had received a Wells notice from the US Securities and Exchange Commission, a letter warning that staff intended to recommend enforcement action over the 2021 listing and private sales of IMX. Immutable called the move overreach and said IMX was not a security. On 25 March 2025 the company announced that the SEC had closed its investigation without taking action, one of several crypto cases the agency dropped that year. Like other tokens, IMX remains subject to the wider rules on cryptocurrency regulation in each country where it is sold.

Blockchain gaming has struggled to keep players once early token rewards fade, and many titles announced during the 2021 boom were delayed or cancelled. Critics argue that tying in-game economies to a traded token can attract speculators rather than players. Immutable also depends on Ethereum for final settlement and on a small number of major games for activity. Moving from Immutable X to Immutable Chain required games, marketplaces and wallets to migrate, and some collections chose custom migration paths, which complicated matters for holders of older items. IMX is listed on major cryptocurrency exchanges and has been highly volatile.
