Choosing a Bundler
Selecting an external Bundler implementation to be used with Particle’s AA SDK.
Bundlers within Particle’s AA SDK
Particle Network’s AA stack is built to be as modular as possible while retaining a central mechanism for managing and sending UserOperations. Thus, the in-house Particle Bundler is used by default when sending UserOperations through the Particle AA SDK (Introduction to Smart Wallet-as-a-Service).
The Particle Bundler is an open-source, fully compliant, feature-rich, high-performance, infinitely scalable 4337 Bundler implementation. However, a core element of Particle’s AA SDK is the ability to build a UserOperation and then send it directly through whatever alternative Bundler you prefer.
The below image showcases the different native and external implementations present in Particle’s AA SDK.
