What is Account Abstraction (AA) and How Do AA Wallets Work?
Summary
This article explains account abstraction, a new technology that could be used to improve the user experience of crypto wallets. Account abstraction separates Externally Owned Accounts (EOAs) from the original and rigid ECDSA (Ecliptic Curve Digital Signature Algorithm) digital signature scheme and the network’s consensus layer. It also allows wallets to function like smart contracts, removing complicated wallet requirements like seed phrases and enabling features like batching complex actions or automatic payments. Possible use cases of account abstraction include improved user experience, no seed phrases, revising the current fee payment system, setting up automatic payments, and batching complex actions. However, there are some barriers to account abstraction acceptance such as compatibility issues with existing smart contracts and potential security risks.
Q&As
What is Account Abstraction in Crypto?
Account Abstraction (AA) enables wallets to function like smart contracts, removing complicated wallet requirements like seed phrases and enabling features like batching complex actions or automatic payments.
How does Account Abstraction work?
Account abstraction separates Externally Owned Accounts (EOA) and smart contracts from the original and rigid ECDSA (Ecliptic Curve Digital Signature Algorithm) digital signature scheme and the network’s consensus layer. It attempts to make EOAs automatable like smart contracts by bypassing the consensus layer using an alternate mempool, a pseudo-transaction, and bundlers to package the transactions and include them in a block for validation.
What are the potential use cases and benefits of Account Abstraction?
Possible use cases for account abstraction include improved user experience, no seed phrases, revising the current fee payment system, setting up automatic payments, and batching complex actions.
What are the possible barriers to Account Abstraction acceptance?
Possible barriers to account abstraction acceptance include compatibility issues with existing smart contracts, higher gas fees, and potential exploitable gaps.
What are the differences between Externally Owned Accounts (EOA) and smart contracts?
Externally Owned Accounts (EOAs) are personal accounts owned and controlled by individuals on the network and are represented by cryptographic addresses. Smart contracts are code bits turned into state-changing instructions and do not use the same signature system as EOAs, allowing developers to engineer automation.

AI Discussion
Me: It's about account abstraction (AA) in crypto and how it works. It aims to make personal wallets function similarly to smart contracts, allowing for automation of core operations like transfers and access to wallets. It could potentially open up the Ethereum network and other EVM platforms to a whole new level of adoption and application.
Friend: That's really interesting! What are some of the implications of this?
Me: Well, it could potentially improve the user experience of blockchain wallets and reduce the need for seed phrases. It could also enable alternative payment structures, automated payments, and batching of complex transactions. It could also help with account recovery and access control. However, it could also lead to more exploitable gaps and potentially higher gas fees.

Technical terms
- Account Abstraction (AA)
- A technology that enables wallets to function like smart contracts, removing complicated wallet requirements like seed phrases and enabling features like batching complex actions or automatic payments.
- ECDSA (Ecliptic Curve Digital Signature Algorithm)
- A digital signature scheme that defines the validation system for Externally Owned Accounts (EOAs) and smart contract accounts. It uses the private and public key pairing system to dictate access management and task execution structure for blockchain accounts.
- Externally Owned Accounts (EOAs)
- Personal accounts owned and controlled by individuals on the network and are represented by cryptographic addresses.
- Smart Contracts
- Code bits used to define a smart contract on the Ethereum Virtual Machine (EVM). Smart contracts do not use the same signature system as EOAs.
- EIP-2938
- A protocol proposed for smart contracts that allows a smart contract to bypass the signature algorithm and extend transaction validity by executing an arbitrary EVM bytecode.
- EIP-4337
- A protocol proposed for EOAs that can be achieved by bypassing the consensus layer using an alternate mempool, a pseudo-transaction, and bundlers to package the transactions and include them in a block for validation.
- zkSync and Starknet
- Layer 2 networks rumored to be working on applications for account abstraction technology.
