Polygon Appchains (e.g., using Polygon CDK or Supernets) excel at providing dedicated, predictable throughput by design. By operating as sovereign chains with a single sequencer, they eliminate block space competition, enabling sustained high TPS tailored to a single application's needs. For example, an Immutable zkEVM gaming chain can achieve 4,500+ TPS for in-game asset transfers, isolated from network congestion from DeFi protocols like Aave or Uniswap.

Polygon Appchain vs General L2: TPS
A technical comparison for CTOs and architects evaluating dedicated appchains like Polygon Supernets against shared L2s like Arbitrum and Optimism for maximum transaction throughput.

THE ANALYSIS
Introduction: The Throughput Dilemma
A data-driven comparison of transaction throughput strategies between dedicated Polygon Appchains and general-purpose Ethereum L2s.
General L2s like Arbitrum, Optimism, and Base take a different approach by offering shared, composable throughput. This strategy results in a trade-off: while peak theoretical TPS can be high (e.g., Arbitrum Nitro's 40,000+ TPS cap), real-world performance is shared among all dApps, leading to variable latency and potential congestion during network-wide events like major NFT mints or airdrops on platforms like Zora.
The key trade-off: If your priority is guaranteed, application-specific performance and sovereignty, choose a Polygon Appchain. If you prioritize immediate composability with a vast ecosystem of existing DeFi, NFTs, and users, choose a General L2. The former is optimal for high-frequency gaming or enterprise use cases; the latter is superior for protocols that thrive on network effects.

Polygon Appchain vs General L2: TPS
TL;DR: Key Differentiators
Raw throughput is just one metric. The architecture behind it determines scalability, cost, and who benefits.
01
Polygon Appchain: Dedicated Throughput
Guaranteed, isolated performance: An appchain provides a dedicated block space, ensuring your dApp's TPS (often 1,000-7,000+) is not shared with or impacted by other protocols like Uniswap or Aave. This matters for high-frequency trading platforms, web3 games, or enterprise applications that require predictable, low-latency execution regardless of network congestion.

General L2 (e.g., Arbitrum, Optimism): Inherited Security & Liquidity
Instant access to shared liquidity: Your dApp deploys into an existing ecosystem with $10B+ TVL and millions of users. Transactions benefit from the collective security of Ethereum via fraud proofs or validity proofs. This matters for DeFi protocols, NFT marketplaces, and social apps that thrive on network effects and composability with established giants like GMX or OpenSea.

THROUGHPUT DECISION MATRIX
Polygon Appchain (Supernet) vs General L2: TPS
Peak TPS is a vanity metric. Real-world throughput is defined by architecture, resource isolation, and cost predictability. Here's the breakdown for high-frequency applications.
01
Polygon Appchain: Dedicated Throughput
Guaranteed, isolated performance: A dedicated Supernet provides a single-tenant execution environment. Your TPS is not shared with other dApps, avoiding the 'noisy neighbor' problem common on shared L2s. This matters for gaming, high-frequency DeFi, and enterprise applications requiring predictable, sub-2 second finality regardless of network congestion.

03
General L2 (e.g., Arbitrum, Optimism): Shared Burst Capacity
High aggregate, contested throughput: Leading Optimistic and ZK Rollups like Arbitrum One and OP Mainnet offer high theoretical TPS (4K-40K+), but this is a shared resource. During peak demand (e.g., an NFT mint), your app's performance degrades. This model fits applications with sporadic traffic that benefit from shared security and liquidity without needing guaranteed slots.

PROS AND CONS
General L2 (Arbitrum, Optimism) vs. Polygon Appchain: TPS
Comparing the transaction throughput philosophies of shared, general-purpose L2s versus dedicated, sovereign appchains.
01
General L2: High Shared Throughput
Optimized for network effects: Arbitrum One and Optimism Mainnet achieve 40-100+ TPS under load, leveraging a shared sequencer and security model. This matters for dApps that benefit from composability (e.g., DeFi protocols like GMX, Uniswap) and don't require absolute performance isolation.
02
General L2: Predictable Cost Scaling
Fee markets are shared but efficient: Transaction costs scale predictably with overall network demand using EIP-4844 blobs. This matters for applications with variable traffic that prioritize cost efficiency over guaranteed latency, as seen with high-volume NFT mints on OpenSea.
03
Polygon Appchain: Dedicated, Predictable TPS
Isolated performance guarantee: A dedicated chain like Polygon CDK or Supernet provides sovereign block space, ensuring your application's TPS (often 1,000+) is never impacted by other dApps' traffic. This matters for gaming (e.g., Immutable zkEVM), high-frequency trading, or enterprise use cases requiring SLA-level consistency.
04
Polygon Appchain: Tailored Fee Structure
Complete control over economics: As the chain operator, you can set your own gas token (e.g., MATIC, USDC, app token) and subsidize or customize fees. This matters for consumer-facing applications (e.g., Reddit's Community Points) where user experience demands stable, near-zero transaction costs.
CHOOSE YOUR PRIORITY
Decision Framework: Choose Based on Your Use Case
Polygon Appchain for DeFi
Verdict: Ideal for established protocols needing sovereignty and predictable performance. Strengths: Full control over MEV, custom fee tokens (e.g., using MATIC for gas), and dedicated throughput prevent congestion from other dApps. This is critical for high-frequency DEXs like QuickSwap or sophisticated lending markets. You can implement app-specific preconfirmations and optimize the EVM for your contracts. Trade-offs: You inherit the security of the Polygon PoS or CDK chain you build on, which may be less decentralized than Ethereum L1. Bootstrapping liquidity and network effects is your responsibility.
General L2 (Arbitrum, Optimism) for DeFi
Verdict: Superior for protocols prioritizing deep, shared liquidity and Ethereum's security. Strengths: Immediate access to massive, composable TVL (e.g., Arbitrum's ~$2B+). Native integration with ecosystem staples like Uniswap, Aave, and Chainlink is seamless. Security is derived from Ethereum via fraud proofs or validity proofs (zkRollups). Trade-offs: You compete for block space. During network spikes, your users face variable fees and potential latency. You cannot customize chain parameters or economics.
verdict
THE ANALYSIS
Verdict and Final Recommendation
Choosing between a dedicated Polygon appchain and a general-purpose L2 like Arbitrum or Optimism is a fundamental trade-off between raw, isolated performance and shared, composable throughput.
Polygon Appchains (e.g., using Polygon CDK) excel at delivering predictable, high TPS for a single application by providing dedicated, isolated block space. This architecture allows a dApp to leverage Polygon's high-throughput consensus (derived from its PoS chain) without competing for resources, enabling sustained throughput of 10,000+ TPS for its specific use case, as seen in deployments like Immutable zkEVM for gaming.
General L2s like Arbitrum, Optimism, and Base take a different approach by offering a shared, composable execution environment. This results in a trade-off: while peak TPS for the entire network is impressive (e.g., Arbitrum Nitro can process ~40,000 TPS internally), your specific dApp's performance is subject to network-wide demand and gas price fluctuations, capping your app's sustainable throughput during congestion.
The key trade-off: If your priority is guaranteed, high-throughput performance for a single, complex application (e.g., a high-frequency DeFi protocol, a web3 game), choose a Polygon Appchain. If you prioritize deep liquidity, seamless composability with top DeFi protocols like Uniswap and Aave, and a large existing user base, even with variable per-app throughput, choose a General L2.
