A Developer’s Guide into Account Abstraction Models
- Accounts abstraction (AA) has been a key factor contributing to the influx of new users to crypto wallets.
- The idea of account abstraction was first proposed in 2015 by Vitalik Buterin, founder of Ethereum, with the aim of creating flexible and adaptable accounts controlled by smart contracts.
- Accounts on Ethereum are objects that constitute the state of the blockchain, including nonce, ETH balance, contract code-hash, and storage.
- Solana accounts are more like storage capable of holding any type of data ranging from tokens to a program’s state variables such as integers, public keys, and entire programs.
- Account Abstraction models describe the process of abstracting away the rigid and built-in structures of accounts within a blockchain, allowing them to be more flexible and adaptable.
- Developers can utilize AA models to create customized and fluid user-friendly on-chain accounts where they can define their own custom logic for storing assets and executing transactions over the network.
- Account Abstraction is an ongoing area of research and development on Ethereum, while Solana has already implemented it through features like Program Derived Addresses (PDAs) and Cross-Program Invocations (CPI).
- One of the core use cases for AA models is the implementation of smart wallets, which offers social account recovery, permissionless asset management, and other advanced features.
- However, one of the challenges to AA models is restraint in limitation of program composability, a practice typically referred to as security through obscurity.
