Transform your high-traffic application into a dedicated blockchain with 1-second block times, sub-cent transactions, and enterprise-grade infrastructure. Base Appchains provide dedicated blockspace for mature applications that need to scale beyond shared network limitations.
Base Appchains are app-specific Layer 3 rollups built on Base that provide dedicated blockspace for individual applications. Instead of competing with thousands of other apps for network resources, you get your own high-performance blockchain that rolls up to Base and inherits Ethereum’s security.
Layer 3 appchains roll up to Base (Layer 2), which settles on Ethereum, providing you with dedicated performance while maintaining the security guarantees of the Ethereum ecosystem.
Think of it as the difference between sharing a highway during rush hour versus having your own dedicated express lane. With shared blockspace, your app’s performance depends on network-wide activity. With an Appchain, you get consistent, predictable performance regardless of what’s happening elsewhere.
Shared Blockspace
Compete with other apps for network resources, leading to variable performance, unpredictable costs, and user experience issues during peak times.
Dedicated Blockspace
Your own infrastructure with predictable performance, custom gas tokens, full control over throughput, and consistent user experience.
Stop letting network congestion impact your user experience. Base Appchains deliver 1-second block times and sub-10 second withdrawals, making them 10x faster than typical blockchain interactions.
Gaming applications like Blocklords have processed over 80 million transactions across 1.8 million wallets using Base Appchains, achieving the scale needed for their gaming ecosystem without performance degradation.
Replace unpredictable gas costs with fixed monthly pricing. Process transactions for fractions of cents while eliminating the need to sponsor gas costs for your users.
Before Appchains
Variable gas costs, expensive user onboarding, unpredictable operational expenses, and complex gas sponsorship management.
With Appchains
Fixed monthly pricing, sub-cent transactions, predictable budgeting, and no gas sponsorship complexity.
Maintain access to Base’s users, liquidity, and developer tools while getting dedicated performance. Your Appchain integrates seamlessly with Smart Wallet, Paymaster, OnchainKit, and other Base ecosystem tools.
Base Appchains are built on the OP Enclave framework, providing fast withdrawals and seamless integration with Base Mainnet. This architecture enables near-instant bridging while maintaining security through innovative proving mechanisms.
OP Enclave Framework
Built on Optimism’s latest technology for near-instant bridging between your Appchain and Base Mainnet. Users can move funds in seconds rather than the typical 7-day withdrawal periods of traditional rollups.
Alternative Data Availability
Uses Amazon S3 for cost-efficient data storage while maintaining security through AWS Nitro Enclave verification. This approach significantly reduces costs while ensuring data integrity and availability.
Custom Permissions & Gas Tokens
Control which contracts can be called on your chain, effectively managing blockspace allocation. Implement custom gas tokens and permission systems while protecting users from censorship through guaranteed deposit lanes.
Immediate State Proving
Unlike traditional rollups that rely on challenge periods, Base Appchains use immediate state proving through secure enclaves, enabling instant finality and faster user experiences.
Base Appchains power applications across gaming, DeFi, and enterprise sectors that require high performance and predictable costs.
Process millions of micro-transactions for in-game actions, NFT trades, and player interactions without network congestion affecting gameplay performance.Success Story: Super Champs chose Base Appchains for consistent throughput, comparing the experience to “gaming on iOS” - smooth, predictable, and reliable.
Base Appchains are designed for mature projects with significant transaction volumes. If you’re just starting out or have low transaction volumes, consider building on Base Mainnet first to establish product-market fit.
Base Appchains are ideal for applications that have outgrown shared blockspace limitations. Use this checklist to determine if an Appchain is right for your project:
High Transaction Volume: Your app generates thousands of transactions daily and performance is affected by network congestion
Significant Gas Sponsorship: You’re spending substantial amounts sponsoring gas costs for users through Paymaster or similar solutions
Performance-Critical Operations: User experience is negatively impacted by variable transaction times or network congestion
Custom Requirements: You need custom gas tokens, specialized permissions, or governance mechanisms not available on shared chains
Predictable Costs: Fixed operational costs are important for your business model and budgeting
If you’re considering launching your own L1 or L2 blockchain, Base Appchains offer a compelling alternative with faster time-to-market, proven infrastructure, and immediate access to Base’s ecosystem.
Base Appchains are currently in beta with a waitlist. We’re working with select partners to refine the platform before broader availability.
1
Join the Beta Waitlist
Complete our application form to be considered for early access to Base Appchains. We prioritize applications from mature projects with clear scaling needs.
Our team will review your application and schedule a consultation to understand your specific scaling requirements, transaction patterns, and technical needs.
During the consultation, we’ll help you determine if an Appchain is the right solution and design the optimal configuration for your use case.
3
Development & Testing
Once approved, you’ll receive access to both testnet and mainnet features. Start with the $1/month testnet to validate your architecture and integration.
Use the testnet environment to test bridging, custom gas tokens, and permission systems before deploying to mainnet.
4
Mainnet Launch
Deploy to production with full enterprise support, monitoring, and maintenance included. Our team provides ongoing support for your Appchain infrastructure.
Full technical support during launch and ongoing operations
Coming Soon: Self-serve, one-click deployment will be available for approved projects, making it even easier to launch and manage your Appchain.
How do Base Appchains compare to launching my own L1 or L2?
Base Appchains offer significant advantages over launching independent blockchain infrastructure:
Faster time-to-market: Deploy in weeks, not months or years
Proven infrastructure: Built on battle-tested Base and OP Stack technology
Immediate ecosystem access: Users and liquidity from Base Mainnet
Lower operational overhead: Fully managed infrastructure and maintenance
Ethereum alignment: Inherit security without custom validator sets or consensus mechanisms
What's the user experience for onboarding to my Appchain?
Base Appchains provide seamless onboarding similar to Base Mainnet applications:
Users can bridge funds between Base and your Appchain in seconds
Same wallet experience across Base ecosystem
Smart Wallet integration for account abstraction
Familiar transaction patterns and interfaces
Do I control the infrastructure of my Appchain?
Coinbase manages the core infrastructure on your behalf, including:
Sequencer operation and maintenance
Node infrastructure and upgrades
Security key management
Monitoring and alerting systems
You maintain control over application-level configurations like gas tokens, permissions, and governance while benefiting from enterprise-grade infrastructure management.
How does bridging work between Base and my Appchain?
Base Appchains use the OP Enclave framework for near-instant bridging:
Move funds between Base and your Appchain in seconds
No 7-day withdrawal periods like traditional rollups
Maintains security through cryptographic proofs
Seamless user experience across chains
What about decentralization and censorship resistance?
Base Appchains balance operational efficiency with censorship resistance:
Custom permissions control high-throughput operations
Guaranteed deposit lanes prevent censorship through direct Base deposits
Users always have recourse through the Base bridge
Base Appchains represent the next evolution in blockchain scaling, providing dedicated infrastructure without sacrificing ecosystem benefits. Whether you’re processing millions of gaming transactions, handling high-frequency DeFi operations, or building enterprise solutions, Appchains deliver the performance and predictability your users expect.
