Web3 contract is a smart contract based on blockchain technology, which can be operated and deployed directly in Web3 applications by using the tools and APIs provided by the Web3 development platform. Web3 contracts are typically written in the Solidity language, they are designed to execute automatically and can record and verify transactions without human intervention. Even with such technology, accidents can happen. What happened to the recent stolen Web3 wallet contract interactions? It has become a hot topic. Web3 contract is a smart contract based on blockchain technology. By using the tools and API provided by the Web3 development platform, it can be operated and deployed directly in Web3 applications. Next, I will give you a detailed answer.
Web3 wallet contract interaction theft usually refers to the theft of cryptocurrency assets or digital assets due to improper operation or malicious behavior when users use Web3 wallets to interact with smart contracts. This situation may occur in various situations such as private key leakage, malicious contracts, fraudulent websites, smart contract vulnerabilities, etc. The following is a detailed introduction:
1. Private key leakage
Web3 wallets are usually used to store users’ private keys, which is an important means of controlling their cryptocurrency. Once a user's private key is stolen, the attacker can control the user's assets and cause serious financial losses. Private keys may be compromised due to malware, phishing attacks, insecure storage or weak passwords. Therefore, users should remain vigilant when using Web3 wallets, ensure to choose a safe and reliable wallet, regularly update software and passwords, and avoid clicking on suspicious links or downloading files from unknown sources to maximize the security of private keys.
2. Malicious contracts
Malicious smart contracts may cause user asset losses. These contracts legitimately attract users to provide funds and then steal the assets.
3. Fraudulent websites
Fraudulent websites may disguise themselves as legitimate Web3 wallets or DApps to defraud private keys and authorization contracts to steal assets.
4. Smart contract vulnerabilities
Some smart contracts may have security vulnerabilities, allowing attackers to exploit vulnerabilities in the contract to steal users' assets.
There are three main ways to prevent Web3 wallets from being stolen. The following are the details:
1. Do not disclose private keys and passwords to others. Mnemonic words, Keystore files, and use physical media to back up these data as much as possible, such as copying them on paper and storing them on non-networked hardware. Try to avoid using Internet-connected devices to save and transmit private keys, or take screenshots and photos to save private keys. Don't import the wallet using the private key provided by others and use the wallet to deposit or receive money.
2. Do not easily authorize Web3 wallet to third-party applications with unknown risks. It is recommended that you understand the background of the project and assess the risks of the project party before authorizing/interacting. Do not click on unknown links. Once you authorize your Web3 wallet to some phishing project, the project will obtain your approved permission to transfer the asset amount, thereby transferring the assets of your wallet.
3. Please check regularly whether the Web3 wallet has authorized unfamiliar sites and cancel the authorization in time. If you find that your wallet has been stolen, transfer the remaining assets to a safe address as soon as possible, delete the risky wallet, re-create a new wallet, and contact official customer service if necessary.
Web3 cannot cancel contract interaction. Because in the Ethereum network, once a transaction is sent and recorded on the blockchain, it cannot be reversed or canceled. This is because of the decentralized design of Ethereum, all transactions are open, transparent and cannot be tampered with. Note that if the Web3 wallet contract interaction is stolen, users should take action as soon as possible, such as reporting the theft to law enforcement agencies, exchanges or relevant platforms, to try their best to recover the stolen assets.
