Understanding pop -Etamask UPS: Deep diving in the code
While working on building a metamascus portfolio, you will probably find the infamous “pop -up” function. When creating a new metamascus portfolio or updating the existing pop -up window opens with a series of instructions, which at the beginning look scary and overwhelming. But what exactly is behind this behavior? In this article, we will delve into the metamask code base to discover the logic for these pop -ups.
code: Look under the hood
To understand how a jumping window appears during interaction with a portfolio compatible with a metamascus, let’s look at the appropriate parts of the code. In particular, we will examine the “Metamask” class in the Web3.js library, which is used to create and manage them.
`Javascript
Import {ethers} with "web3";
Import * as a metamask "./Meetamask";
Metamask class {
Builder (supplier) {
this.provider = supplier;
This.KEYPAIR = new ethhers.keypair ();
}
Async inteit () {
// Initiate a wallet with a pair of standard keys
}
Async createaccount (conccountname) {
// Create a new account using the Metamask supplier and the name given
}
}
The “metamask” class has several methods that seem to be related to the creation of the account, but one of these methods raises the eyebrows: “Createaccount”. When you call this method, the following are followed by:
`Javascript
Async createaccount (conccountname) {
Account conct = aguiart this.init ();
Return the new Metamackccount (this.provider, account.keypair, account name);
}
Let’s look at the Metamaskcount class now.
`Javascript
Metamackccount class extends ethers.cotract {
Builder (contracts, supplier, name) {
Super contracts, supplier, name;
}
asynchronous Createaccount (keyboard, name) {
// Use a pair of keys to sign a transaction creating an ethereum account
}
}
“Createaccountin Metamackccount uses the” KeyyPair “object (which is created using the” Metamask ‘initial method) to sign the transaction. After calling this method, the pop -up opens with instructions that seem to be related to the account configuration.
logic for pop -up
After some excavation of the metamas code, we find some tips that can help explain why pop -up appears:
- This means that the account creation process is associated with a used specific supplier.
- The “CreateCcount” method probably uses these data stored to sign transactions and create an account.
- POP appearance -P : When you call the “Createaccount`, pop -up method appears due to the specific instructions provided by Metamask. These instructions may include creating a new portfolio or creating an existing one.
Application
To sum up, a pop -up window, which opens to interaction with a portfolio compatible with Metamasc, is probably associated with logic creation processes and specific accounts of the supplier associated with the used supplier. Although modifying the original code is not possible without accessing confidential information (such as private keys), we can deduce how this behavior works based on Metamask mechanics.
Tips for building your own portfolio
If you are building your own Metamask wallet, remember that:
- Use the specific logic of the supplier to create accounts.
- Store key pairs and other confidential information about local storage.
- Provide specific instructions for a portfolio or specific account instructions.
