Account abstraction (AA) has emerged as a transformative force in the Web3 ecosystem, streamlining how users interact with blockchain networks. By simplifying wallet creation, transaction management, and gas fee handling, AA is redefining onboarding for new users. The year 2023 marked a pivotal period for its adoption, with explosive growth across major Ethereum-compatible chains. This article dives into the data behind account abstraction’s rise, analyzes key drivers, and explores what this momentum could mean for the future of decentralized applications.
Understanding Account Abstraction and ERC-4337
At the heart of this evolution lies ERC-4337, a standardized protocol that enables account abstraction without requiring changes to Ethereum’s core consensus layer. Unlike traditional externally owned accounts (EOAs), which rely solely on private keys, smart contract wallets under ERC-4337 allow for advanced features like social recovery, multi-signature approvals, and gasless transactions.
The EntryPoint contract, deployed on January 1, 2023, acts as a central coordinator for user operations (user ops). It validates and bundles transactions from smart contract wallets before they’re executed on-chain. This infrastructure layer has become foundational to AA's scalability and security.

By August 30, 2023, over 616,000 unique accounts had been created using ERC-4337, generating more than 1.3 million user ops. The growth between Q1 and Q2 was staggering — a 11,837% increase in user ops and over 27,000% surge in new users — signaling strong developer and user interest.
Key Chains Driving Adoption
Four networks dominate the current landscape: Ethereum, Polygon, Optimism, and Arbitrum. As of September 2023, these chains collectively hosted over 520,000 ERC-4337 accounts, with the vast majority (over 80%) created during July and August alone.
- Polygon led in both account creation and user activity.
- Optimism saw rapid uptake driven by innovative wallet solutions.
- Arbitrum and Ethereum lagged slightly but showed steady foundational growth.
Paymasters and Bundlers: The Backbone of Gasless Transactions
Two critical components enable seamless user experiences: paymasters and bundlers.
Paymasters: Enabling Gasless Interactions
A paymaster is a smart contract that covers gas fees on behalf of users. This allows dApps to sponsor transactions — for example, letting gamers play without holding native tokens or enabling social platforms to cover onboarding costs.
By mid-2023:
- There were 96 active paymasters.
- Total gas sponsored reached approximately $414,200.
- Transaction volume grew by 5,182% quarter-over-quarter, reflecting rising demand.
This infrastructure is crucial for mass adoption, removing one of the biggest friction points in Web3: managing multiple tokens just to pay gas.
Bundlers: Aggregating User Operations
Bundlers collect multiple user ops and submit them as a single transaction to the EntryPoint. They ensure efficiency and reduce congestion.
As of September 2023:
- Around 1,300 bundlers were active.
- Generated roughly $33,800 in revenue.
- On Ethereum, StackUp dominated with 94% market share, highlighting centralization concerns despite rapid development.
While centralization poses risks, it also reflects early-stage ecosystem maturity — where a few robust providers lead innovation before broader decentralization takes hold.
Chain-Specific Highlights
Polygon: The Leader in User Adoption
Polygon stands out as the frontrunner in account abstraction adoption:
- Over 340,000 accounts deployed.
- More than 560,000 user ops, with 440,000 occurring in July 2023 alone.
- Responsible for 43.9% of total user ops and 47% of wallet adoption share.
The surge was largely fueled by the launch of CyberConnect, a decentralized social network that mandates ERC-4337 wallets for all users. Additionally:
- Biconomy supported nearly 30,000 account deployments.
- Infrastructure was powered primarily by Pimlico, which provided bundling and paymaster services during peak growth months.

Optimism: Innovation Through Wallet Design
Optimism recorded:
- 150,000 accounts.
- 400,000 user ops by September 2023.
Growth accelerated in August due to two key developments:
- Beam Wallet: Introduced flexible gas payment options — users can pay fees using any token they’re transferring, not just OP.
- ZeroDev SDK: A developer toolkit built on ERC-4337 that simplifies building AA-powered dApps.
Infrastructure support came from Pimlico, Alchemy, and StackUp, with StackUp’s SDK enabling customizable transaction flows — making Optimism an attractive environment for builders.
Arbitrum: Steady Growth with Developer Focus
Arbitrum showed more modest numbers:
- Approximately 2,200 accounts.
- Around 18,000 user ops.
Growth in mid-2023 stemmed primarily from:
- Integration with ZeroDev and Biconomy.
- Experimental use cases and testing by developers.
Most bundler and paymaster services were operated by StackUp, indicating reliance on centralized infrastructure during early development phases.
Ethereum: Foundational but Slow-Moving
On the mainnet:
- Only 339 accounts.
- Just over 2,100 user ops.
Despite being the base layer, Ethereum’s high gas costs and slower UX improvements have limited widespread AA deployment. Most activity came from:
- ZeroDev (primary contributor).
- Projects like Safe and Biconomy conducting limited tests.
- Users interacting with liquid staking tokens (e.g., stETH, cbETH).
However, Ethereum remains the ultimate destination for scalability once L2 solutions mature and rollups achieve full interoperability.
Frequently Asked Questions (FAQ)
What is account abstraction?
Account abstraction replaces traditional key-based wallets with smart contract wallets, allowing customizable logic for transaction execution — such as multi-sig, session keys, or gas sponsorship.
Why did adoption spike in mid-2023?
The surge was driven by product launches — notably CyberConnect on Polygon and Beam Wallet on Optimism — combined with improved infrastructure from providers like Pimlico and StackUp.
Which blockchain leads in account abstraction?
Polygon leads in both user numbers and transaction volume, thanks to large-scale integrations and strong developer tooling.
Are there risks with dominant bundler providers?
Yes. High concentration (e.g., StackUp controlling 94% of Ethereum’s bundlers) poses potential centralization risks. However, this is expected to balance as more players enter the space.
Can regular users benefit from account abstraction?
Absolutely. Benefits include social recovery (no lost keys), gasless transactions, batched operations, and better UX — making Web3 more accessible than ever.
Is ERC-4337 secure?
ERC-4337 has undergone extensive auditing and real-world testing since its January 2023 deployment. While no system is immune to bugs, its design incorporates safeguards like reputation systems for bundlers and rate limiting.
Final Thoughts: A Sign of Mainstream Momentum?
The data paints a clear picture: account abstraction is gaining traction at an unprecedented pace. With over half a million accounts created in just nine months — most within a single summer — the foundation is being laid for mass Web3 adoption.
Core keywords driving this trend include: account abstraction, ERC-4337, smart contract wallets, paymasters, bundlers, Web3 onboarding, gasless transactions, and Polygon blockchain — all reflecting growing interest in usability-focused innovations.
As infrastructure matures and competition increases among service providers, we can expect greater decentralization, improved reliability, and broader integration across dApps. The goal is no longer just technical feasibility — it's about delivering a seamless experience that rivals traditional web platforms.
