Overview
How hardware wallets, multi-sig setups, and operational security practices protect your assets. The definitive guide to not getting hacked.
Self-custody is the foundational principle of crypto -- 'not your keys, not your coins.' The collapse of centralized exchanges has proven that trusting third parties with your assets carries existential risk. This guide covers everything you need to protect your holdings.
Hardware wallets (Ledger, Trezor, Keystone) store your private keys offline, making them immune to remote attacks. For higher-value holdings, multi-signature wallets (Gnosis Safe, Squads) require multiple approvals for transactions, eliminating single points of failure. The choice between convenience and security depends on your threat model and portfolio size.
Operational security extends beyond your wallet. Phishing attacks, clipboard malware, SIM swaps, and social engineering are the most common attack vectors. Use a dedicated device for high-value transactions, verify addresses character by character, use a hardware security key for exchange accounts, and never share your seed phrase -- not even with support teams claiming to help.
