Best blockchain game development companies in 2026: how to choose

A studio planning to move part of its game onto a blockchain network already has almost everything else in place: engine, servers, player accounts, inventory and an economy with its currencies and rewards. What it has to decide is which items become tokens the player controls outside their account, who issues and manages those tokens, and what happens to them if the game changes or shuts down. The companies that show up when you search for "blockchain game development" answer different parts of that decision: there are networks designed for games, kits for integrating wallets and contracts into Unity or Unreal, and NFT platforms with their own chain.

This guide brings together Metlabs and five references with public documentation that cover those three offerings. Metlabs publishes this page and develops the blockchain layer for game assets and economies, although it does not develop video games; the selection is commercial, not an independent or exhaustive ranking. The data comes from each company's official website and documentation, checked on November 8, 2026; products, networks and ownership may have changed since, and in this sector they have changed several times over the past year.

The six companies at a glance

What to compare before choosing a blockchain game development company

The first criterion is which layer the studio wants to keep. If the game, engine and economy are its own and it only needs certain items to exist as tokens, it is looking for a developer of that layer or an SDK. If it prefers to rely on a network with wallets, a marketplace and a community already in place, it hires a platform and accepts its rules. If it has no game team, it needs a studio. Within each option, four questions separate providers:

• Network and exit: which network the assets live on, who decides how it evolves, and how they are migrated if the studio changes provider.
• Accounts and keys: whether the player holds their tokens or an embedded wallet does, and who signs the game's transactions.
• Operating costs: who pays the gas for each player action and what limits apply to that sponsorship.
• Integration: how inventory, servers, marketplace and player support connect with what happens on-chain.

The second question defines how much real control the player has. An item in a wallet only they control can leave the game and be sold outside its marketplace; one in a wallet managed by the studio is closer to an internal record with better traceability. Both options are legitimate, but the studio has to explain them to players in the same terms its license uses.

Metlabs: your game's blockchain layer, built to order

Metlabs is a blockchain development studio based in A Coruña, Spain, that designs, audits and deploys infrastructure for game assets and economies for studios that keep their own game, engine and servers. It does not develop gameplay or art: it builds the contracts for items and collectibles, the wallet integration, the marketplace and the connection to the game backend, with an in-house technical team and +30 projects in production across different sectors.

The work starts from a decision studios often postpone: which items are recorded on-chain and which stay on the server. Keeping combat and progression in the game's systems and publishing on the network only the operations a third party needs to verify, such as a limited issuance or a transfer between players, reduces cost and friction. For tokens we use the ERC-721 and ERC-1155 standards with persistent metadata and defined transfer permissions, as in our NFT development service.

What to ask for in a proposal for your game

• An asset inventory by function: consumables off-chain, transferable items and limited issuances in contracts.
• Asset contracts with documented admin permissions, including metadata changes and item suspension.
• Wallets and account recovery suited to players, with the cost of each operation visible before confirming.
• A shutdown plan: what the player keeps, which metadata is exported and which features go away.

This approach fits a studio that wants to choose its network, keep control of its economy and be able to change infrastructure provider without rebuilding its assets. If the studio prefers a network with a community and marketplace already in place, the platforms below cover more with less in-house development. To compare on the same scope, tell us which assets your game has and what players should be able to do with them.

Immutable: chain, wallet and growth channel for games

Immutable offers studios a platform that covers the network, the player account and distribution. Its documentation describes Passport, for authentication and embedded wallets, and Chain, which groups an indexer, an order book, checkout and asset contracts, with SDKs for TypeScript, Unity and Unreal. The chain is presented as optimized for games and built on Ethereum; it is EVM-compatible and supports Solidity with Foundry or Hardhat, and its mainnet is called Immutable zkEVM.

Its difference from the other platforms is that it also sells growth: its website presents player acquisition, attribution and campaign tools alongside the infrastructure. For players, Passport users pay no gas because the platform sponsors it, which simplifies the experience and leaves that cost and its control with Immutable. One point for planning: its documentation states that the current testnet will stop being available for games by the end of 2026, as part of a migration to the OP Stack, so a project starting now should plan for that change.

Ronin: Sky Mavis' chain, now an Ethereum L2

Ronin is the network that Sky Mavis, the company behind Axie Infinity, describes as an EVM chain built for games with player-owned economies. Its documentation offers a developer console for creating and selling NFTs without code, Mavis Market for launches and secondary trading, Ronin Store for selling in-game items, and Proof of Distribution, a program that distributes RON to registered contracts based on their activity.

The relevant change in 2026 is its architecture. According to the Ronin blog, in May the network stopped being an independent chain and became an Ethereum L2 built on the OP Stack, in a migration led by Conduit, and it keeps RON as its gas token. For a studio, that brings the network's security closer to Ethereum's without changing the player experience. In return, building on Ronin means joining an ecosystem with its own community, marketplace and incentives, which is its main appeal and also the dependency the studio takes on.

Sequence: wallets and payments for the network the studio chooses

Sequence does not offer its own network but the pieces a game needs to work with EVM networks. Its documentation describes non-custodial wallets with social or email sign-in, ecosystem wallets with passkeys and time-lock recovery, an indexer for balances and activity, Trails for cross-chain payments, and Unity and Unreal SDKs that include wallets, indexer, payments and marketplace tools.

Its corporate situation has changed. On January 13, 2026, Polygon Labs announced that it had signed definitive agreements to acquire Sequence and Coinme and bring them into its Open Money Stack, a stablecoin payments infrastructure. The gaming SDKs are still documented, but the product is now also geared toward payments. For a studio, the advantage is not being tied to one network; the question worth asking is what priority the gaming tools will have on the new owner's roadmap.

thirdweb: SDKs for your team to build the integration

thirdweb offers development tools for on-chain applications, games among them. Its Unity SDK is presented as the way to build cross-platform games on any EVM network: it connects wallets, interacts with contracts and signs messages, and includes in-app wallets, ecosystem wallets and account abstraction. It also publishes an Unreal SDK and, on its website, a toolkit for creating ERC-20, ERC-721 and ERC-1155 tokens.

It is the option in this guide that leaves the most work to the studio's team. thirdweb provides the components; designing the economy, deciding what goes on-chain, integrating with the servers and running the system afterwards falls to whoever develops the game. It fits a studio with developers able to take on that integration who want to avoid writing the wallet and contract connection to the engine from scratch.

Enjin: protocol-level NFTs on its own chain

Enjin takes a different approach: instead of deploying contracts for each collection, its network handles them in the protocol. According to its documentation, Enjin Matrixchain runs on the Enjin Relaychain, includes fungible and non-fungible tokens with capped or uncapped supply without additional contracts, and offers Fuel Tanks to subsidize fees for specific player actions.

Developers access it through the Enjin Platform, a hosted GraphQL API, with C# and C++ SDKs as the first releases. Transactions are signed by the Wallet Daemon, a service the studio runs on its own infrastructure, so keys never leave its environment; if the encrypted seed or its password is lost, the wallet may become unrecoverable. It fits games built around collectible items that are willing to work on a specific network in exchange for not writing contracts.

Which blockchain game company to choose: the one that leaves the studio in control of its economy, with a way out

The six offerings in this guide do not compete for the same thing. Immutable and Ronin sell an ecosystem with chain, wallet, marketplace and community; Sequence and thirdweb sell components for the studio to build with; Enjin handles assets in its own protocol; and Metlabs develops the blockchain layer to order so the studio keeps the rest. The past year shows why the choice is not only technical: Ronin changed its architecture, Sequence agreed to a new owner, and Immutable is retiring its testnet for games.

That is why the criterion that best protects both studio and player is control. A game whose assets live in contracts the studio understands, with documented permissions, keys held by the studio or the player, and a migration plan, can change provider without breaking the promise made to whoever bought an item. That promise is what blockchain adds to a game: that players actually control what they own. Before signing, ask each candidate to explain what happens to the assets if the relationship ends.
