Biconomy is building infrastructure allowing developers to enable effortless experiences for their users. Our Account Abstraction stack offers a plug and play modular framework which enables customers to define user journeys and customisability of actions a user can take on their dapp or wallet all in a non custodial manner. These can include sponsored transactions, paying gas in any token, automated transactions/session keys, account recovery, and many more. Biconomy leverages account abstraction offered by EIP-4337 to offer this functionality and offers the full stack solution, including a gas optimised and highly modular smart accounts implementation and infrastructure such as paymasters and bundlers.

Our Account Abstraction Stack has 4 key components.

2. Passkeys (Biometric login using FaceID or fingerprints)
3. Any form of social login and/or any MPC provider (ie: Facebook, Google, Twitter, Microsoft, Email, Phone login)

2. Smart Account modules
