Wallet (III) - BIP32
2. Derivation rules [BIP32].
We generated a seed through BIP39, which we call the 'master seed'. According to the derivation rules of BIP32, we can derive the 'master private key', 'master public key', and 'master chain code' from the 'master seed', all three of which are referred to as 'keys'. We can continue to derive 'child keys' (child private key, child public key, child chain code) from the 'keys' as 'child seeds', and so on, allowing for an infinite generation of descendants, all derived from the 'master seed'; hence, the 'master seed' is also referred to as the 'root'. The 'master private key', 'master public key', and 'master chain code' are also referred to as the 'master keys'. As long as we back up the 'mnemonic phrase', we can export the 'root' -> 'master root' -> 'child root', etc.

Wallet (I)
I. Overview
The choice and use of wallets are closely related to us retail investors. I found that many newcomers are not very familiar with wallets and do not know how to use them. Essentially, a wallet is a container that generates and saves private and public keys and addresses, responsible for signing with the private key, encrypting with the public key, receiving payments with the generated address, or receiving change with the generated address during a transaction. At the same time, it continuously accesses the Bitcoin network to calculate your wallet balance and display it to you.
When you give someone your Bitcoin address and they send money to that address, the Bitcoin balance displayed in your wallet will change. After you send money to someone, in addition to the Bitcoin you paid them, they also need to give you change, so you need to provide a change address, similar to receiving change in everyday life.

#钱包 shares a little trick for saving wallet private keys or mnemonic phrases. In the field of computer science, there is a concept called erasure coding, which involves splitting data into multiple redundant segments and storing them in a distributed manner. Even if some segments are lost or damaged, the original data can still be recovered. To give a simple example:
Mnemonic phrases can be divided into three parts: A, B, and C. AB is stored in one place, BC is stored in another place, and AC is stored in a third place. Only two of the three locations are needed to recover the original mnemonic phrase, so it doesn't matter if one is lost or leaked.
You can divide it this way as you like, splitting it into 4 parts or 5 parts is also fine.

ScaleBit: A zero-day vulnerability has been discovered that allows the transfer of all assets from the Uniswap Wallet, existing in the latest version of the Uniswap iOS wallet, Version 1.42.
This vulnerability allows attackers with physical access to the device to bypass the wallet's authentication mechanism and directly access the mnemonic phrase stored on the device. #钱包 #安全

"Be careful! There are scammers rampant in the square. Once the mnemonic is lost, it is almost impossible to recover it!"
"Let's popularize some basic knowledge: there are a total of 2048 mnemonics, and you can choose 12, 15, 18, 21 or 24 words to form a set of keys when creating a wallet.
If you need to recover your wallet, it may be because the order of the mnemonics is wrong or the words are spelled wrong.
In this case, it is feasible to write a program to traverse within a limited range (I can provide a simple program that only needs 1000U to generate addresses and get balances);
But in other cases, unless you are a god, there is almost no possibility. Think about it, how can Satoshi Nakamoto's address still have money for many years.
"Never use a wallet recommended by others, otherwise your money will be gone, so instead of giving it to others, it is better to give it to me. "

Recently, An has quite a few wallet activities,
Is something big going to happen?
First sign up, then go trade.
I won’t participate in Activity Two, just focus on Activity One,
Dividing 51500U/5000 people = 10U, enough for a meal of pig's feet!
Brothers, go go go!
Hope Binance organizes more activities like this,
And wish Binance Wallet gets better and better!

MetaMask launches staking service for validators
MetaMask has announced the launch of a new staking service that allows users to pay to run its validator nodes.
MetaMask noted that it will run validator nodes on behalf of users who deposit 32 Ethereum tokens. Additionally, these users will always retain control over their funds and accounts. Let’s explore this important feature further.
MetaMask launches validator staking: a new era begins
The goal of this new service is to make it easier and more secure for users to access Ethereum’s proof-of-stake network. Additionally, the new MetaMask service will make it easier for users without the technical knowledge to set up and maintain validator nodes, as it eliminates hardware pooling and maintenance.

《A New Paradigm for Wallets! Safe ($SAFE) Analysis and Token Fundamentals》
Wallets are essential infrastructure in Web3. Whether for DeFi interactions, meme transactions, or basic transfers, everyone needs a wallet to connect to the Web3 world. I have previously organized the classification of wallets (Web3 Wallet Guide), and to better understand Safe, I recommend reading my previous articles in advance.
Wallets that are frequently used, such as Binance Wallet and Metamask, are controlled by single corporate entities, while Safe has directly moved the wallet on-chain, achieving stronger functionality and interaction experience, while ensuring decentralized characteristics.

How can I check whether my wallet address is authorized, multi-signed, or has its permissions changed?
Recently, digital assets have been frequently stolen. Due to the decentralized design and high anonymity of blockchain technology, it is almost impossible to recover digital assets once they are stolen. Developing good wallet usage habits and regularly checking the token authorization and signature status in the wallet can effectively reduce the risk of asset theft. So how do you check whether your wallet address is authorized and multi-signed?
Let’s take the TRON chain as an example:
1. First open the TRON blockchain browser
2. Enter your wallet address in the browser address bar
3. Click the authorization list to view the authorization details of the token. As shown in the figure, if there is no authorization, it means that your account authorization is safe.
