Account Abstraction

User-centric design lies at the heart of SFI L2, with account abstraction (AA) serving as a key feature to achieve this goal. Traditional blockchain accounts—Externally Owned Accounts (EOAs)—force users to manage private keys and tokens for transaction fees, creating a steep learning curve for newcomers. SFI L2 addresses this challenge through AA by decoupling these systems and replacing them with programmable smart accounts.

Account abstraction offers users features like gasless transactions, allowing dApp operators to subsidise fees or enabling users to pay in their preferred tokens. This flexibility proves invaluable in scenarios where onboarding non-crypto-native users is critical. Furthermore, programmable smart accounts allow for the integration of custom logic directly into wallets, facilitating automated approvals, role-based access, and security enhancements such as multifactor authentication.

By abstracting complex blockchain interactions, account abstraction not only lowers barriers to entry but also opens doors to innovative use cases, ranging from automated payments to AI-driven portfolio management.
