What is a Bundler?

A 4337 Bundler is a network participant that packages user operations (transactions) and submits them to your chain. This integration deploys a bundler and all the contracts required for 4337 account abstraction.

What is Account Abstraction?

Account Abstraction allows wallets to be programmable, turning them into smart contracts. This breaks away from the limitations of EOAs and opens up a wide array of possibilities for wallet functionality, including flexible gas payment models, multi-factor authentication, and recovery mechanisms.

What is ERC-4337?

ERC-4337 is an Ethereum standard that introduces Account Abstraction allowing for the creation of smart contract-based wallets. This standard is specifically focused on improving user experience by enabling advanced features like:

• Batching transactions: Users can bundle multiple operations into a single transaction, reducing complexity.
• Custom signature verification: Wallets can support different cryptographic methods for signing transactions (e.g., biometrics, multi-sig).
• Gasless transactions: "paymasters" can sponsor gas, enabling users to interact without holding native tokens.
• Social recovery: Wallets can be designed to allow recovery mechanisms via trusted contacts.
