Cryptocurrency purchased from an exchange does not 'go' to a physical location, but is recorded at an address on the blockchain network. Here is a detailed explanation:
### 1. Exchange custodial wallet (default storage location)
When you purchase cryptocurrency from an exchange (like Binance, Coinbase, etc.), the assets are **by default stored in the wallet address controlled by the exchange**. At this point:
- You do not directly control the private key: The exchange manages user assets centrally like a bank, and what you see is the digital balance in the exchange account.
- Exchange ownership management: Assets are actually stored in the exchange's 'hot wallet' (online) or 'cold wallet' (offline), managed collectively by the exchange.

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.

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.

Is there anyone who can crack the password?

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.

Uncovering the U-stealing fraud industry chain: It takes five minutes to deposit $500,000 into a bank, but it only takes less than a second for it to be gone once you click on the U-stealing link.

Now domestic scammers are upgrading from traditional telecommunications fraud to virtual currency fraud. Hello everyone, today I will reveal the complete U-theft fraud industry chain for you.

First of all, we need to know what USDT theft is. In simple terms, it is the act of stealing or transferring USDT from other people's digital wallets by various means. So why do scammers target USDT theft? The reason is also very simple. Virtual currency is not protected by law in China. When victims go to China to report the case, many uncles in hats don't know what USDT is. Some uncles in hats directly tell you that it is not protected by law, and they will not file a case for investigation. Often the victims can only blame themselves for their bad luck.

I believe everyone is worried that the assets they have earned through hard work in the currency circle will be stolen by hackers due to their own carelessness. Everyone must have seen someone lose their assets through an airdrop.
At this time you will hear the word "wallet", and then you will start to wonder what this wallet is. Next, I will tell you about it. It is all practical information and take notes.

cold wallet
A cold wallet usually refers to a location where you store your private keys that cannot be accessed by the network. It is a non-networked wallet, also known as an offline wallet. Cold wallets rely on "cold" equipment to ensure the security of digital currency private keys. When not connected to the Internet, they can use computers, mobile phones, and small notebooks with private key addresses written on them. When users use cold wallets, since the outside world generally cannot access the location where their private keys are stored through the network, they avoid the risk of hackers stealing their private keys, thus improving the security of digital assets.

In the previous issue of the Web3 Security Beginner's Guide to Avoiding Pitfalls, we mainly explained the risks when downloading/purchasing wallets, how to find the real official website and verify the authenticity of the wallet, and the risk of private key/mnemonic leakage. We often say "Not your keys, not your coins", but there are also situations where even if you have a private key/mnemonic, you cannot control your assets, that is, the wallet has been maliciously multi-signed. Combined with the MistTrack theft form we collected, some users' wallets were maliciously multi-signed, and they didn't understand why there was still a balance in their wallet accounts but they couldn't transfer the funds out. Therefore, in this issue, we will take the TRON wallet as an example to explain the relevant knowledge of multi-signature phishing, including the multi-signature mechanism, hackers' routine operations, and how to avoid malicious multi-signatures on wallets.
