A data-driven comparison of Arbitrum One's battle-tested performance versus Arbitrum Orbit's customizable scalability.
Arbitrum One excels at delivering a high-performance, stable environment for general-purpose applications. As the flagship L2, it leverages a single, optimized Nitro stack to achieve a proven throughput of over 40,000 TPS in internal benchmarks, with real-world performance consistently high for mainstream DeFi protocols like GMX and Uniswap. Its strength lies in shared security and network effects, boasting over $18B in TVL.
Arbitrum Orbit takes a different approach by enabling developers to launch their own dedicated chains (L3s or L2s). This results in a fundamental trade-off: you gain sovereignty and can tune parameters (e.g., gas pricing, fee token, privacy) for potentially higher localized throughput, but you inherit the responsibility of bootstrapping your own validator set and liquidity, moving away from Arbitrum One's unified liquidity pool.
The key trade-off: If your priority is immediate access to deep liquidity, maximal security, and a proven user base, choose Arbitrum One. If you prioritize sovereignty, customizability for a specific application, and are prepared to bootstrap your own ecosystem, choose an Arbitrum Orbit chain.
Transaction throughput is a function of architecture, not just a single number. Here's how the mainnet and its L3 framework compare.
Sustained High Throughput: Processes ~40,000 TPS on its AnyTrust chain (Nitro). This is a battle-tested, production-ready network with deep liquidity (e.g., GMX, Uniswap). Ideal for protocols needing immediate access to a massive, secure ecosystem.
Contention for Block Space: All dApps compete for the same sequencer's capacity. During extreme network congestion (e.g., a major NFT mint), your app's TPS is limited by the overall network load, not your own needs.
Dedicated Execution Lane: Each Orbit chain (L3) has its own sequencer, providing guaranteed, isolated throughput. A gaming chain can achieve its own 10,000+ TPS without being affected by activity on Arbitrum One or other Orbit chains.

Key strengths and trade-offs for transaction throughput at a glance. TPS is a function of architecture, not just a headline number.
Specific advantage: Processes ~40,000 TPS on its AnyTrust chain (Data Availability Committee) with real-world stress tests. This matters for high-frequency dApps like perpetual DEXs (GMX, ApeX) and gaming protocols that require consistent, high-volume settlement on a secure, established L2.
Specific advantage: All TPS benefits from the shared security and ~$2B TVL of the main Arbitrum One rollup. This matters for DeFi protocols where cross-app composability (e.g., Aave deposits funding GMX trades) is critical; high TPS is meaningless without deep, accessible liquidity pools.
Specific advantage: Developers can optimize TPS for cost by selecting cheaper DA, enabling sub-cent fees at scale. This matters for mass-market applications (social, gaming) requiring millions of micro-transactions where Ethereum DA fees would be prohibitive, trading off some decentralization for extreme scalability.
Specific trade-off: Peak TPS is still shared across all dApps. During network congestion (e.g., major NFT mint), your app's throughput can be impacted. This is a problem for mission-critical, predictable performance needs where you cannot control the activity of other protocols on the chain.
Specific trade-off: High, isolated TPS on an Orbit chain does not automatically grant access to Arbitrum One's liquidity. Requires custom bridging solutions (Stargate, LayerZero). This is a problem for new DeFi primitives that need immediate access to deep capital pools to be viable.
Transaction throughput is a primary differentiator. Arbitrum One offers a proven, shared network, while Orbit provides customizable, dedicated capacity. Here are the key trade-offs.
Sustained high capacity: Processes ~40,000 TPS on its Nitro stack, with real-world peaks exceeding 100,000 TPS. This matters for applications requiring immediate, high-volume liquidity on a major L2 like GMX or Uniswap.
Cost efficiency at scale: Transaction fees are amortized across the entire network's activity, keeping costs predictable and low for end-users during normal loads.
Shared resource model: All dApps (DeFi, Gaming, Social) compete for the same block space. This matters for time-sensitive protocols that cannot tolerate potential congestion from unrelated network events, leading to variable latency.
Throughput ceiling: While high, the TPS is ultimately capped by the single sequencer and fraud proof window, a hard limit for projects forecasting exponential user growth.
Isolated performance: Each Orbit chain (e.g., Xai Games, D8X) owns its sequencer and can be configured for its specific TPS needs, from hundreds to thousands. This matters for gaming studios or enterprise apps that require guaranteed, low-latency execution unaffected by external DeFi activity.
Vertical scalability: Throughput scales with the underlying Data Availability (DA) layer choice (Ethereum, Celestia, EigenDA), allowing for tailored cost/performance.
Isolated liquidity pools: An Orbit chain's TPS is dedicated but its liquidity is not natively shared with Arbitrum One or other Orbits. This matters for DeFi protocols that require deep, composable liquidity from day one, necessitating complex bridging solutions.
Operational overhead: Achieving high TPS requires actively managing and funding the chosen DA layer and sequencer, adding complexity versus using a managed service like Arbitrum One.
Verdict: The default choice for established protocols. Strengths:
Verdict: Ideal for novel, high-throughput DeFi primitives. Strengths:
Choosing between Arbitrum Orbit and Arbitrum One for TPS is a strategic decision between custom performance and proven network effects.
Arbitrum Orbit excels at providing customizable, high-throughput environments because it allows you to deploy your own dedicated L3 or L2 chain. This enables you to architect for specific TPS needs, bypassing shared sequencer bottlenecks. For example, an Orbit chain can be configured with a high gas limit per block and a fast block time, theoretically supporting thousands of TPS in a controlled environment for applications like high-frequency gaming or order-book DEXs.
Arbitrum One takes a different approach by offering a single, highly optimized L2 with massive network effects. This results in a trade-off: while its shared sequencer currently caps throughput for individual applications (peaking at around 40-80 TPS for sustained periods), it provides instant composability with a $18B+ TVL ecosystem, including protocols like GMX, Uniswap, and Lido. Its performance is a proven, battle-tested metric for mainstream DeFi and NFT applications.
The key trade-off: If your priority is predictable, dedicated throughput and architectural control for a specific high-volume application, choose Arbitrum Orbit. If you prioritize immediate access to liquidity, users, and proven network stability, where your app's TPS will align with the broader chain's organic growth, choose Arbitrum One.
