Sequence has established itself as a strong contender in the web3 gaming space, offering a smart wallet and infrastructure stack tailored for games. However, game studios often find themselves needing more flexibility, open-source components, or a pricing model that scales better with their specific game economy.
If you are evaluating Sequence or looking for alternatives that offer greater sovereignty and modularity, here are the top choices in 2025.
1. Openfort
Openfort (that's us 👋) is an open-source wallet infrastructure solution that provides powerful wallet capabilities to abstract crypto complexity for both users and developers. Its platform allows developers to plug and play any signer (including OpenSigner) and contract they prefer, simplifying the whole vertical use case—from cross-app ecosystems and AI agents to fintech and DeFi.
Key Features
- If you're currently using Sequence and hitting limits around vendor lock-in (proprietary stack), want to use your own custom authentication system without wrappers, or need a self-hosted option for compliance or control.
- Open source, Self-hosting option, Vendor neutrality: Openfort's entire stack—from the embedded wallet signer to the smart account infrastructure—is open-source. You can self-host it to ensure you never lose access to your player base. Learn more about how to avoid wallet vendor dependency.
- Concrete example: You are building a cross-platform MMO and want to use your own custom "Player ID" backend for auth, while spinning up smart accounts that are portable across your mobile and PC clients, without relying on Sequence's specific login methods.
Comparison Table: Openfort vs. Sequence
| Feature | Openfort | Sequence |
|---|---|---|
| Open Source | ✅ (OpenSigner) | ❌ |
| Smart Accounts | ✅ Modular (4337, 7702) | ✅ Native (Proprietary) |
| Gaming SDKs | ✅ Unity | ✅ Unity, Unreal |
| Authentication | Any OIDC / Custom | Sequence Auth |
| Vendor Lock-in | ❌ None (Exportable) | ⚠️ High (Proprietary Stack) |
| Gas Sponsorship | ✅ Granular Policies | ✅ Built-in |
| Session Keys | ✅ Flexible | ✅ |
| Self-Hostable | ✅ Yes | ❌ No |
| Pricing | MAU + Usage (Free Tier) | Custom / Game-focused |
Scaling Considerations
- High User Volume, Low Transaction Volume: Openfort's free tier covers 1,000 MAUs and 500 transactions, which is great for indie games launching their beta. You can grow your player base significantly before paying.
- Transaction Orchestration: Sequence offers a vertically integrated stack, but Openfort provides a modular orchestration layer. This means Openfort handles the transaction complexity (bundling, paymasters) while letting you plug in any signer or auth provider, avoiding the "walled garden" approach.
- Low User Volume, High Transaction Volume: Openfort's transaction pricing is transparent. In high-frequency gaming scenarios (e.g., on-chain moves), Openfort's session keys and batched transactions can significantly reduce gas costs compared to standard implementations.
Why developers choose Openfort
Game developers choose Openfort when they want the gaming-native features of Sequence (session keys, gasless txs) but demand open-source infrastructure and no vendor lock-in for their game's long-term health.
2. Thirdweb
Thirdweb is a massive development platform that includes gaming SDKs. Thirdweb offers a Unity SDK and embedded wallets that compete directly with Sequence's offering.
Comparison Table: Thirdweb vs. Sequence
| Feature | Thirdweb | Sequence |
|---|---|---|
| Ecosystem | Full Stack (General) | Gaming Dedicated |
| SDKs | Unity, Unreal | Unity, Unreal |
| Marketplace | ✅ Built-in | ✅ Built-in |
| Smart Accounts | ✅ Integrated | ✅ Native |
| Pricing | Bundle Model | Game Model |
Scaling Considerations
Thirdweb is great for generalist needs.
- Choice: If your game also needs complex smart contract deployment tools (drops, editions), Thirdweb's dashboard is superior. Sequence is better if you need deep gaming-specific features like an indexer.
Why developers choose Thirdweb
For the ease of use and the comprehensive dashboard that manages contracts, payments, and wallets in one place.
3. Privy
Privy (acquired by Stripe) is increasingly being used in gaming for its onboarding conversion. While not a "gaming" wallet per se, its conversion rates make it a top contender.
Comparison Table: Privy vs. Sequence
| Feature | Privy | Sequence |
|---|---|---|
| Conversion | Best-in-Class | Good |
| Gaming SDKs | ⚠️ Limited (Unity beta) | ✅ Robust |
| Smart Accounts | ⚠️ Partner Integrations | ✅ Native |
| Marketplace | ❌ | ✅ |
| Focus | Consumer Apps | Games |
Scaling Considerations
Privy is expensive but converts well.
- Fit: Use Privy if your game is a lightweight browser game or PWA. Use Sequence if you need deep Unity integration and inventory management.
Why developers choose Privy
For browser-based games where onboarding speed is the critical metric.
4. Dynamic
Dynamic (acquired by Fireblocks) is also expanding into the gaming sector. Dynamic offers a great embedded wallet that can be used in gaming contexts.
Comparison Table: Dynamic vs. Sequence
| Feature | Dynamic | Sequence |
|---|---|---|
| UI | Polished Widget | Custom / Headless |
| Gaming SDKs | ❌ | ✅ Unity, Unreal |
| Smart Accounts | ⚠️ Basic | ✅ Native |
| Auth | Strong | Strong |
| Pricing | MAU-based | Game-based |
Scaling Considerations
Dynamic is less gaming-optimized.
- Gap: Dynamic lacks the gaming-specific SDKs (Unity/Unreal) that Sequence and Openfort provide.
Why developers choose Dynamic
Mostly for web-based gaming or gambling apps that don't require a game engine integration.
Building In-House Wallet Product
Building your own gaming wallet infrastructure is a massive undertaking.
Pros
- Player ID: Total control over the player identity system.
- Cost: Avoid SaaS fees at scale.
Cons
- Distraction: You are building a game, not a wallet company.
- Security: Gaming wallets are high-value targets for hacks.

FAQ
1. Does Openfort support Unity? Yes, Openfort has a robust Unity SDK that supports all platforms (mobile, desktop, webGL).
2. Can I migrate from Sequence to Openfort? Yes. Since Openfort uses standard smart accounts, you can migrate users. However, Sequence's proprietary stack might make exporting private keys difficult depending on your setup.
3. Is Sequence custodial? Sequence is non-custodial (smart wallet), but their "Waas" offering relies heavily on their infrastructure for signing.
Conclusion
Sequence is a strong all-in-one solution for web3 games.
However, if you need open-source flexibility, modular components (bring your own auth), or broader ecosystem compatibility, Openfort is the best alternative for building scalable web3 games.
