Why Every Rollup Will Eventually Be an AA Rollup
Account Abstraction is not a feature—it's the new base layer. This analysis argues that native AA support will become as fundamental to a rollup's survival as an EVM, driven by developer demand, user expectations, and the relentless competition for the next billion users.
introduction
THE ARCHITECTURAL SHIFT
The Inevitable Primitive
Account abstraction is not a feature but the foundational architecture for all scalable rollups.
EOAs are a design flaw. Externally Owned Accounts hardcode cryptographic primitives and payment logic, creating a rigid user experience bottleneck. Rollups inheriting this model inherit its limitations.
The market demands it. Protocols like Starknet and zkSync launched with native AA. Arbitrum and Optimism are actively integrating it via ERC-4337 and RIP-7560. User adoption on Particle Network and Biconomy demonstrates demand.
Evidence: Over 3.6 million ERC-4337 smart accounts have been created. The bundler infrastructure from Stackup and Alchemy proves the economic model works at scale.

WHY EVERY ROLLUP WILL EVENTUALLY BE AN AA ROLLUP
The Tectonic Shifts Forcing AA's Hand
Modularity and user-centric design are converging to make native account abstraction the only viable endpoint state for scalable blockchains.
01
The Modular Stack Demands a Neutral Endpoint
Rollups are unbundling execution, settlement, and data availability. The user-facing endpoint—the execution client—must be neutral to avoid vendor lock-in and enable permissionless innovation.
- Decouples wallet logic from the core protocol, allowing for rapid iteration on UX.
- Enables shared sequencers and interoperability layers (like LayerZero, Hyperlane) to function without protocol-level integrations.
- Turns the rollup into a generalized state transition machine, where the 'account' is just another program.

Intent-Based Architectures Are Winning
Users want outcomes, not transactions. Systems like UniswapX, CowSwap, and Across prove that delegating transaction construction to a competitive solver network is superior UX.
- Native AA (e.g., a
validatefunction) is the prerequisite for secure, generalized intent fulfillment on L2s. - Solver competition drives down costs and improves execution quality, impossible with fixed EOA logic.
- Paves the way for native gas sponsorship, batched operations, and atomic multi-chain intents.

The Inevitable Commoditization of L2 Execution
As rollup frameworks (OP Stack, Arbitrum Orbit, Polygon CDK) mature, execution becomes a low-margin commodity. The only durable moat is user experience and developer adoption.
- Native AA is the ultimate UX primitive, enabling social recovery, session keys, and gasless onboarding.
- Developer attraction: Building with native AA (like Starknet, zkSync) is fundamentally easier than hacking around EOA limitations.
- Future-proofs the chain against emerging standards (ERC-4337, RIP-7560) becoming mandatory.

The Security Calculus of Programmable Validity
EOAs are the weakest link, responsible for ~$1B+ in annual losses from phishing and key mismanagement. A rollup's security model is incomplete if it ignores the account layer.
- Native AA allows for transaction simulation and pre-execution safety checks at the protocol level.
- Enables formal verification of account logic, making smart contract wallets inherently safer than EOAs.
- Reduces systemic risk for the entire ecosystem by moving security upstream from user error.

The AA Adoption Gap: Leaders vs. Laggards
A feature and economic comparison of rollup approaches to Account Abstraction, highlighting the structural advantages of native integration.
| Key Dimension | Native AA Rollup (Leader) | Bundler-as-a-Service (Laggard) | EOA-Only Rollup (Legacy) |
|---|---|---|---|
AA Protocol Layer | Native protocol primitive (e.g., Arbitrum Stylus, zkSync native AA) | External smart contract (e.g., Biconomy, Pimlico, Stackup) | Not applicable |
Gas Sponsorship Model | Protocol-level sponsor whitelist & batched gas accounting | Relayer network with off-chain payment rails | User-pays-all (impossible) |
UserOp Throughput Limit | Bounded by L1 calldata & L2 execution (10k+ TPS) | Bottlenecked by singleton bundler contract (< 1k TPS) | 1 tx per EOA signature |
Average UserOp Cost | $0.01 - $0.05 (batched L1 settlement) | $0.10 - $0.30 (premium for relay service) | $0.50 - $2.00 (standard EOA L2 tx) |
Session Key Security | Native session key revocation in state tree | Smart contract allowlist management | Not applicable |
Protocol Revenue Stream | Captures 100% of AA-related gas fees | Cedes fee capture to third-party bundlers | Base L2 fee only |
Developer Integration | Single SDK for core L2 + AA (e.g., zkSync SDK) | Multiple SDKs: L2 RPC + Bundler API + Paymaster API | Standard EOA wallet tooling |
Upgrade Path for dApps | Atomic L2 state updates with AA actions | Cross-contract coordination risks | Requires full user migration |

THE INEVITABLE PATH
The Slippery Slope to Native AA Dominance
The technical and economic incentives for rollups to natively integrate Account Abstraction are overwhelming, making it a question of 'when', not 'if'.
Native AA is a scaling lever. Externally Owned Accounts (EOAs) are a bottleneck for transaction throughput. Native AA, by decoupling transaction validation from signature schemes, enables batch processing and signature aggregation, directly increasing a rollup's effective TPS without modifying core execution.
The economic model demands it. Rollup revenue is a function of L1 data costs and sequencer efficiency. Native AA allows for sponsored transactions and session keys, which increase user activity and sequencer fee capture, creating a direct revenue flywheel that EOA-based models cannot match.
The competitive landscape forces adoption. Once one major rollup like Arbitrum or Optimism implements native AA, it sets a new UX standard. Competing chains must follow or cede developers and users to platforms with gasless onboarding and social recovery.
Evidence: The L1 Precedent. Ethereum's own roadmap, with EIP-7702 and the Verkle tree transition, is a canonical commitment to deprecating EOAs. Rollups that build on this foundation, like those using zkSync's native AA, are future-proofing their architecture against obsolescence.

THE FRICTION
The Bear Case: Why This Might Not Happen
The transition to Account Abstraction rollups faces significant technical, economic, and governance inertia.
Native L1s resist abstraction. Chains like Solana and Sui are built on native account models; retrofitting AA requires a fundamental protocol rewrite. The performance and security trade-offs for existing, high-throughput ecosystems are prohibitive.
Sequencer revenue models conflict. Rollups like Arbitrum and Optimism monetize transaction ordering. AA's intent-based mempools and solver networks (e.g., UniswapX, CowSwap) externalize this value capture, creating a direct economic disincentive for the core development team.
User experience gains are marginal. For power users with established EOA workflows and hardware wallets, the smart account benefits—social recovery, batch transactions—are not compelling enough to justify protocol-level complexity and potential new attack surfaces.
Evidence: Ethereum's own ERC-4337 adoption remains niche after a year, dominated by a few bundled paymaster services. This demonstrates that even with a clear standard, network effects and developer momentum are not guaranteed.

Architecting the Future: Who's Building the AA-Native Stack
Account abstraction is not a feature; it's a foundational shift. These are the protocols building the primitives that make AA-native rollups inevitable.
01
The Problem: Native AA Requires a New VM
EVM's rigid transaction model is incompatible with AA's flexible user operations. Rollups need a new execution environment designed for intent-based interactions.
- Key Benefit: Enables native batching & parallel execution of user ops.
- Key Benefit: Reduces gas overhead by ~30% by removing legacy opcodes.

THE INEVITABLE SHIFT
The 24-Month Horizon: The Great Rollup Re-Architecture
Account abstraction is not a feature; it is the foundational architecture for all future rollups.
Account abstraction is infrastructure. It decouples transaction execution from key management, enabling programmable logic for fees, security, and batching. This creates a modular user layer that rollups must adopt to compete.
EOA wallets are a dead-end. Externally Owned Accounts (EOAs) lock users into primitive, single-key security and rigid fee payment. Smart contract wallets like Safe and Argent demonstrate the demand for superior UX and security.
Rollups compete on user experience. The winning L2 will offer native gas sponsorship, batch transactions, and session keys. This requires AA, making it a core protocol primitive, not a bolt-on.
Evidence: Arbitrum and Optimism already implement native AA support via ERC-4337. zkSync Era and Starknet launched with AA as the default, proving its viability at scale.

WHY EVERY ROLLUP WILL BE AN AA ROLLUP
TL;DR for Busy Builders
Account abstraction isn't a feature; it's the inevitable end-state for scalable, user-centric blockchains. Here's the first-principles breakdown.
01
The UX Bottleneck is a Protocol Problem
Native EOA wallets are a dead end. Gas sponsorship, batched transactions, and session keys are impossible without protocol-level support. AA solves this by making the smart contract wallet the primary account.
- Enables native gas abstraction and sponsored transactions.
- Unlocks complex intents via session keys and transaction batching.
- Removes seed phrase friction, the single biggest user onboarding barrier.

Security is a Feature, Not a Constraint
Critics argue AA introduces smart contract risk. The counter: a well-audited, canonical Account protocol is more secure than the endless vulnerabilities of poorly implemented EOA-based multi-sigs and cross-chain bridges.
- Centralizes security auditing on one core contract.
- Enables programmable recovery and fraud detection.
- Reduces attack surface vs. bridging assets to Layer 1 for management.
