Web3 gaming companies: compare the infrastructure layer first
Web3 gaming companies span game development, player accounts, blockchain infrastructure, asset operations and payments. Start with the part of the player journey you need to build. These six examples cover different layers, and several suppliers work across more than one. Product scope was reviewed on 30 September 2026.
| Company and layer | Published scope | What to test before selecting |
|---|---|---|
| ImmutableGaming platform and player identity | Immutable combines gaming infrastructure with player-growth products. Passport provides wallet and identity functions using email or social sign-in. Its developer documentation covers chain services and TypeScript, Unity and Unreal SDKs. Immutable developer overview | Demonstrate account linking, recovery, minting and inventory display on the intended device. Identify sponsored transactions and show what happens when sponsorship is unavailable. |
| SequenceWallets, game SDKs and asset interfaces | Sequence offers wallets, payments, indexed balances and marketplace interfaces, with web, mobile, Unity and Unreal tooling. Ecosystem Wallet uses authentication and application-specific permissions. Sequence platform documentation | Test session expiry and revocation, an allowed action and a refused action. Check wallet, indexer and marketplace support individually against the same chain and asset requirements. |
| ThirdwebApplication wallets and transaction tools | thirdweb distinguishes user, ecosystem and server wallets. Its SDKs include Unity and Unreal; wallet authentication and transaction sponsorship are separate integration decisions. thirdweb wallet documentation | Choose the wallet model first. Test account recovery and a sponsored transaction that should be refused by policy. Confirm the exact features available in the selected engine SDK. |
| AlchemyDeveloper infrastructure and blockchain data | Alchemy provides JSON-RPC access, indexed data, notifications and smart-wallet services. Availability varies by chain and network, with a product and method support matrix. Alchemy feature support by chain | Prove inventory reads, transaction submission and notifications on the actual network. Test delayed or duplicate events and an RPC outage; record a fallback and usage costs. |
| FireblocksAsset control and treasury operations | Fireblocks provides MPC wallets, transaction policies and treasury workflows. Direct Custody is described as self-custody technology; its capabilities differ from Embedded Wallets. Fireblocks wallet-model comparison | Record who controls key shares, approvals and recovery. Demonstrate a refused withdrawal, an approval quorum and an audit export. Check network and exchange support for the selected wallet model. |
| MoonPayFiat-to-crypto purchasing | MoonPay’s on-ramp embeds a crypto purchase flow in a website or app. The documented journey includes authentication, payment selection, identity checks and asset delivery. MoonPay on-ramp documentation | Confirm acceptance of the business model, country, asset and payment method. Test success, cancellation and failure in a sandbox, and assign refund, support and reconciliation responsibilities. |
Write the player journey first
Decide what the player needs to do: sign in, receive an asset, trade it, transfer it or use it in another part of the game. Mark the moments where a signature, payment or external account would interrupt play. Choose the browser, mobile or game-engine target before comparing SDKs. A chain choice alone does not solve identity, support or marketplace design.
Which on-chain actions genuinely improve the game experience?
Must a player understand wallets or pay transaction fees to begin?
Separate identity from control of assets
Authentication, wallet creation, transaction permission and recovery are different responsibilities. Public wallet documentation describes different ways to assemble these services. Ask each candidate to show who can sign, how permissions are granted and revoked, and what happens when an account or device is lost. Have legal and security specialists assess the intended custody model.
Who can recover access, and what evidence is required?
Can a compromised game session move assets beyond the intended action?
Check support at the component level
A provider may support a chain in one service but not in another. Record compatibility separately for the wallet, engine SDK, asset contracts, indexer and marketplace. Test the exact asset type and transaction flow in the intended environment. Keep roadmap promises out of the production-ready column until they can be demonstrated.
Which required components are available now on the target chain?
Which dependencies are operated by another organisation?
Budget for transactions and sponsorship
If the game sponsors transaction fees, define which actions qualify, how abuse is limited and what happens when a budget or service limit is reached. Estimate costs from a realistic player journey and test load, not only a successful demonstration transaction. Separate provider charges, network fees and internal operating costs.
Can sponsorship be limited by action, user and time window?
What does the player see if sponsorship is unavailable?
Design for pending and failed operations
A submitted transaction is not necessarily a completed gameplay action. Model pending, confirmed and failed states and reconcile them with the game server. Consider indexer delays and any additional steps or waiting periods in a bridge flow. Support teams need a way to find the relevant transaction without asking players to expose private keys.
How is a delayed indexer distinguished from a failed transaction?
Can the game safely retry an action without issuing duplicate assets?
Evaluate security, portability and operating scope
Request the relevant audit scope, incident process and data-export or migration options. Rehearse how players retain access if a service changes or the game switches provider. The companies below offer different layers of infrastructure; inclusion does not imply identical features, guaranteed interoperability, or permission to operate gambling products. Confirm commercial and legal suitability independently.
