Wallet security hygiene extends beyond device choice to encompass backup discipline, access separation, software updates, and phishing awareness. Most preventable losses stem from operational failures rather than protocol flaws.
Segregate hot wallets used for daily activity from cold storage holding significant balances. Limit smart contract approvals, review connected applications regularly, and maintain documented recovery procedures.
Teams should define who holds signing authority, under what approval conditions, and how continuity is maintained when key personnel are unavailable.
Security hardening reduces risk but cannot guarantee immunity from compromise; post-incident response should follow structured evidence preservation practices.
