Essential Privacy and Security Tools for Crypto Investors

Crypto investors can use privacy and security tools to reduce risks from irreversible blockchain transactions and publicly visible holdings. Proton Mail provides zero-access encryption, hide-my-email aliases and phishing protection; its free plan includes 1 GB of storage, while Mail Plus offers 15 GB and up to 10 aliases. GoPlus Security checks dApps, smart contracts, wallet addresses and websites for risks such as rug pulls and honeypot tokens, and reported more than 28 million wallet users in 2025. Blockaid simulates transactions before signing and has helped prevent about $13.1 billion in theft across integrated platforms including Coinbase Wallet, MetaMask and OpenSea.
