The Appchain Advantage
Traditional blockchain deployment forces you to choose between scalability and composability. With appchains, you get both.Sovereignty Meets Settlement
A based appchain combines the advantages of running an appchain (such as customizability, scalability, and sovereignty) with the benefits of deploying a smart contract on its base layer (such as composability and simplicity). Key Benefits:- Scalability - Dynamically adjust gas limits to support high throughput and user demand
- Stability - Avoid “noisy neighbor” issues with tx fee isolation and dedicated execution
- Accessibility - Seamlessly tap into parent chain’s existing liquidity and users
- Profitability - Capture more value with customizable fee structures and token models
- Sovereignty - Full control over infrastructure, fees, and brand identity
- Simplicity - Minimal infra to setup and manage—e.g. no duplicative oracle deployments
Comparison: Appchains vs Alternatives
| Feature | Traditional L2s | Bridge Solutions | Appchains |
|---|---|---|---|
| Composability | Native | Async (risky) | Synchronous |
| Scalability | Shared resources | Single chain limits | Dedicated |
| Customization | Limited | None | Full control |
| Setup Time | Minutes | Hours | Minutes |
| Trust Model | Sequencer | Bridge operators | Fraud proofs |
Migration Considerations
For New Applications
- Start with Appchains - Build with composability from day one
- Future-proof - Your app grows with the ecosystem
- Lower complexity - No bridge integrations or async handling
For Existing Applications
- Gradual migration - Start with read operations, expand over time
- Maintain UX - Users don’t need to learn new interfaces
- Preserve liquidity - Tap into existing settlement chain ecosystems
The Based Appchain Promise
We’re building toward a future where every appchain can compose with every other appchain under the same settlement layer. This creates:- Unified liquidity across all applications
- Atomic operations spanning multiple chains
- Simplified developer experience - write once, compose everywhere
