of the most secure blockchains thanks to its robust decentralized architecture and its *Proof of Stake* (PoS) consensus mechanism. The network is backed by thousands of nodes distributed globally, making it difficult for attacks or manipulations. Security increases with the participation of validators, who must lock up ETH as collateral, incentivizing them to act honestly to avoid losing their funds.

Smart contracts, although powerful, can have vulnerabilities if not well audited. However, tools such as *formal verification* and security audits by specialized companies reduce risks. Additionally, Ethereum has constant updates to improve its resistance to attacks, such as *The Merge* and future scalability improvements.

Despite its security, there are risks such as *smart contract exploits*, *phishing*, or human errors. Therefore, users should use secure wallets, verify transactions, and avoid interactions with unverified contracts. Overall, Ethereum offers a high level of security, but individual responsibility also plays a key role in asset protection.
