Account Abstraction
Overview
Account Abstraction (referred to here as “AA”) is a concept that separates the transaction logic from the specific constraints imposed by Externally Owned Accounts (referred to here as “EOA”) on the blockchain. In Ethereum, accounts can be divided into two types: EOAs controlled by private keys and Contract Accounts (referred to here as “CA”) controlled by programmatic code logic.
While there are two types of accounts, most wallet users are likely more interested in choosing a safer and more convenient wallet than focusing on the type of account. AA leverages smart contracts, enabling users to perform more flexible and customizable transaction validation, offering various security advantages compared to EOAs, which are subject to cryptographic constraints.
Benefit of Account Abstraction
Increased Flexibility
Allows implementation of custom logic for transaction validation.
Supports features such as multi-signature wallets and social recovery.
Improved User Experience
Users can handle customized transactions without directly managing private keys, increasing convenience.
Enhanced Security and Recovery
Can apply new cryptographic algorithms.
Provides features such as social recovery and programmable key management, enhancing security.
Use Case of Account Abstraction
Wallet Flexibility
Smart contract wallets operate independently without an EOA, providing easy access to account recovery, fee management, and multi-signature functionality.
Gasless Transactions
Allows the use of tokens other than ETH for fee payments, or enables third parties to pay the fees on behalf of the user, reducing the burden of paying gas fees.
Programmable Account Logic
Operates based on code rather than private keys, allowing users to program various transaction approval conditions. Users can set complex rules such as multi-signature, delayed execution, and hierarchical approval structures.
Account Abstraction on Silicon Network
The Silicon Network has deployed the ERC-4337 standard's EntryPoint 0.7.0 contract and related systems. The EntryPoint address is identical to that of Ethereum, and it has been deployed with the exact same code as the official repository.

World's First Account Abstraction-Friendly Blockchain Explorer
The Silicon Network's Blockchain Explorer is optimized for ERC-4337's UserOperation. It provides detailed information on various UserOperations executed through EntryPoint and interprets them.
In UserOperation, detailed information such as Paymaster, Batch Execution, Events, and RawData, in addition to basic property information, is provided.
In Transaction, you can check whether UserOperations exist and view detailed information in a list format.
In Account, you can view the list of UserOperations executed by an AA account, similar to a regular transaction list.
