Understanding of the Flag Issystem in Zksync projects
In Zksync projects, the Issystem flag plays a crucial role in guaranteeing the safety and integrity of user accounts. While you are working on the abstraction of your project, it is essential to understand how this flag works.
What is Issystem ‘?
The Flag Isssystem is a setting that determines whether an account in Zksync is considered owned by the user. By default, if the ISSystem flag is set up on true, all accounts are treated as a system account. This means that users cannot directly create or modify these accounts.
How does the Issystem flag work?
When settingIssystem: TrueIn the Hardhat.config.js' file, Zksync will perform the following checks:
- Creation of the user account
: When a user tries to create an account, Zksync will verify that they have sufficient funds to cover transaction costs.
- Properties of the account : If the user's portfolio has a sufficient balance or is associated with an external wallet (for example, book Mastro or Trezor), Zksync will assume that the user has the account.
- Account transactions : When a user makes a transaction on the blockchain, Zksync will verify that they have the permission to make these transactions.
Advantages for the safety of the use ofIssystem
The main purpose of theIssystem ‘flag is to guarantee the safety and integrity of user accounts in Zksync projects. By treating all accounts as a system account, you can:
- Prevent access and changes in unauthorized account
- Protect from potential exploit or tampering by harmful actors
Example of use of the case in the Hardhat configuration
`Javascript
Module.exports = {
// … Other configurations …
Hardhat.config.js: `
Const {Isssystem} = Requirement ('@Zksync/Contractkit');
Module.exports.issystem = True;
,
};
In this example, the FlagIssystemis set to True, ensuring that all accounts in Zksync are treated as system accounts.
Conclusion
The flag of Isssystem 'is a fundamental setting in Zksync projects and understanding its behavior is essential for the creation of safe and robust abstraction solutions. By setting this flag on "True, it is possible to guarantee the safety and integrity of the user accounts, protecting from potential threats and safety exploits.
