The Particle Account Abstraction Bundler Just Crossed 1M UserOps! Fuelling Adoption Across dApps

Dear community, 

We are thrilled to announce that the Particle Bundler has surpassed 1 million transactions! 

Just over two months away from its open-source release, this milestone underscores the growing adoption of Particle's solutions among Web3 developers across chains. This also establishes Particle Network as a leading player in the account abstraction (AA) ecosystem.

The Particle Bundler: A catalyst for ERC-4337 account abstraction

The Particle Bundler is a crucial component of Particle Network's Modular Smart Wallet-as-a-Service infrastructure, packaging multiple UserOperations from multiple sources for execution via an entrypoint. This optimization greatly reduces transaction costs and execution times, making it more efficient for end-users to navigate dApps.

Crossing 1 Million UserOps represents a considerable step forward for Particle Network and the broader account abstraction ecosystem. It demonstrates the growing demand for streamlined user flows, and the role that Particle's infrastructure plays in supporting this growth.

Bootstrapping account abstraction across networks

Notoriously, the Particle Bundler has experienced its adoption across multiple blockchain networks, some of which had no previous dedicated Bundlers. These include:

• opBNB (Mainnet):Our Bundler has facilitated over 400 thousand UserOps in opBNB
• OpBNB (Testnet): Over 40 thousand UserOps. The collaboration between Particle Network and opBNB also produced a record-breaking figure of over 100,000 UserOperations in just four days, making this the fastest-growing ever AA implementation.
• Viction: Over 47 thousand
• Scroll Sepolia: Over 74 thousand.
• Combo Testnet: Over 53 thousand.
• Taiko: over 259 thousand.
• Lumoz Testnet: Over 58 thousand. 
• ZetaChain: Over 70 thousand.

The above chains represented 99% of the Bundler’s activity, which has also been used on Networks like Polygon, Ethereum, Avalanche, and Linea. These attainments highlight the increasing popularity and overall use of Particle's account abstraction Bundler across the Web3 ecosystem. This confirms the Bundler’s ability to effectively manage large transaction volumes, and Particle Network’s growing role in the ERC-4337 scene.

Advantages of the Particle Bundler

Particle's Bundler presents several advantages, making it an integral component of the ERC-4337 ecosystem:

• Seamless UserOperations: We have implemented the persistence of UserOperations, Smart Account Nonce management, and automatic batch sending of User Operations, among different features. The Particle Bundler streamlines the transaction process for users, facilitating the submission of User Operations. This enriches the accessibility of ERC-4337, making it more user-friendly and accessible to a wide audience.
• Smart Ops: We know the importance of steady and dependable operational features for developers, so we have integrated functionalities like Bundler Signer configuration, automated recharging, automated blocking and recovery, and automated monitoring alerts, enabling effortless management and automatic expansion. The era of multi-chain Web3 is still developing, so we have streamlined the process of deploying to new chains down to the execution of a single command with minimum additional configurations. Thanks to this, support for a new chain can be completed within 5 minutes.
• High performance: Particle's Bundler is built for optimal performance and is capable of managing pressing workloads efficiently. Leveraging custom technology and optimization techniques, the Bundler ensures transactions are processed swiftly and effectively.
• Stability: Stability is a hallmark feature of Particle's Bundler. Built with reliability in mind, it works seamlessly even under pressing conditions. Its robust architecture and adherence to best practices in infrastructure management contribute to exceptional stability, providing users and developers with a reliable platform to solve their needs.

As a high-performance, stable Bundler implementation, we also present the following features:

Features

• All standard RPCs supported.
• Configurable RPCs, Signers, etc.
• Support for any chain.
• UserOp Persistence.
• UserOp Concurrent Handling.
• Built-in Gas Price Oracle.
• Multi-Bundler Signers Manager.
• Auto-fulfill bundler Signers’ balance.
• Auto-retry for failed transactions from a Bundler Signer account.
• Returns the correct transaction even when affected by MEV.
• Deploy new chains with one command.

Get started

To get you started, we have official Bundler Endpoints supporting practically all mainstream public chains. You can find these at our documentation:
