Web3 security is one of the main challenges in the era of blockchain and smart contracts. Web3 applications rely on smart contracts that are automatically executed on decentralized networks like Ethereum. However, these contracts, if not programmed carefully, can have serious vulnerabilities that lead to the theft or loss of digital assets. Some of the most prominent threats include: reentrancy attacks, privilege escalation, and dealing with untrusted data from external sources (Oracles). To improve Web3 security, tools for analyzing smart contracts, manual security audits by experts, and adopting best programming practices such as input validation and resource limits must be used. Continuous system updates and educating users are also important elements. In the Web3 environment, security is not an added feature but a fundamental necessity to ensure trust and the sustainability of the system.
