Architecture Overview
Introduction
We are building an application-specific Layer-2 blockchain using Arbitrum Orbit, with Base as the settlement layer, and a bridged gas token model to optimize both user experience and cost efficiency.
This architecture is designed to combine the strengths of:
Arbitrum’s proven rollup technology
Base’s liquidity and fast-growing ecosystem
A flexible gas abstraction layer for smoother onboarding
Our goal is to deliver scalable execution while remaining fully aligned with Ethereum security and composability.
Why Arbitrum Orbit
Arbitrum Orbit allows us to deploy a customizable rollup with full control over core parameters, including:
Execution environment
Fee model
Governance rules
Upgrade path
Unlike general-purpose Layer-2s, Orbit enables us to tailor the chain specifically for application-level performance, without inheriting unnecessary constraints.
Key Benefits
EVM compatibility — seamless integration with existing tooling
Battle-tested fraud-proof system
Independent block production
Modular and flexible upgradeability
This gives us the freedom to optimize where it matters, while relying on a mature and secure rollup framework.
Settlement on Base
Our Layer-2 settles on Base, allowing us to leverage:
Ethereum-level security guarantees
Base’s strong and growing liquidity network
Direct composability with the Base ecosystem
By choosing Base as the settlement layer, we reduce ecosystem fragmentation while aligning with one of the fastest-growing Ethereum Layer-2 environments.
Bridged Gas Token Model
Instead of forcing users to acquire a native gas token upfront, we introduce a bridged gas token mechanism.
How It Works
Gas fees are paid using a bridged token
The bridge abstracts settlement and accounting
Users interact without managing multiple native assets
Why This Matters
This design:
Lowers onboarding friction
Improves UX for non-crypto-native users
Enables future gas sponsorship or gasless transaction flows
The gas layer is designed to be flexible, extensible, and user-centric.
Execution Flow (High Level)
At a high level, the execution and settlement flow works as follows:
Transactions are executed on the Orbit-based Layer-2
Blocks are produced independently by the L2
State roots are periodically submitted to Base
Final settlement inherits Ethereum security via Base
Gas accounting is handled through the bridged token layer
This separation allows us to scale execution without compromising settlement guarantees.
Design Philosophy
We are not building “another generic L2”.
Our objective is to create an efficient execution layer that:
Minimizes user friction
Remains Ethereum-aligned
Stays modular for long-term evolution
We prioritize:
Simplicity over complexity
Composability over isolation
Real usability over speculative narratives
What This Enables
This architecture unlocks:
Application-specific rollup optimization
Lower and more predictable fees
Seamless integration with Base-native liquidity
Future support for gas abstraction and account abstraction
It provides a strong foundation for building scalable, user-focused applications.
Closing
By combining Arbitrum Orbit, Base settlement, and a bridged gas token model, we are building a Layer-2 designed for practical scalability and real users, not short-term hype.
This is a foundation meant to be built on — gradually, transparently, and sustainably.
