Account Abstraction (AA) brings smart account capabilities to users, enabling features like gasless transactions, batched operations, and programmable account logic. Particle Network provides a full-stack Account Abstraction SDK, designed for developers who want to implement ERC-4337 Smart Wallet-as-a-Service with minimal effort. Whether paired with Particle Auth (MPC-secured EOAs) or integrated externally, the SDK handles the heavy lifting of smart account deployment and UserOperation management.
Account Abstraction

​
Understanding Account Abstraction

From a technical standpoint, Account Abstraction (ERC-4337) separates account logic from EOAs, replacing them with Smart Accounts. These programmable accounts allow for improved UX while staying fully decentralized. The Particle AA SDK enables developers to:
  • Deploy smart accounts bound to EOAs (MPC-secured via Particle Auth or external).
  • Construct, sponsor, and send UserOperations.
  • Retrieve fee quotes and handle gas sponsorship.
  • Support recovery flows and custom logic.

​
Key Features

​
User Experience

  • Gasless transactions through paymaster sponsorship.
  • Batched operations (e.g., approve + swap in one click).
  • Programmable logic for recovery, spending limits, or custom policies.

​
Developer Benefits

  • Full ERC-4337 support out of the box.
  • Works natively with Particle Auth (MPC EOAs) or external wallets.
  • Simple SDK integration for constructing, simulating, and sending UserOperations.
