Crypto Wallet Security (2026)

Self-custody basics after exchange onboarding.

SiteBartar Research · Updated June 2026

Exchange hygiene

Authenticator app 2FA; avoid SMS-only — SIM swap risk is real.

Withdrawal whitelist addresses after test small send to each new address.

Separate email for exchange account — not reused with public newsletter signup.

avoid-crypto-exchange-hacks FAQ patterns — phishing peaks during price volatility.

Log out of exchange apps on shared devices; use app PIN/biometrics.

Self-custody path

Hardware wallet for long-term hold — verify device from vendor site only.

Test recovery phrase backup offline — metal backup optional for fire/water risk.

Wrong network withdrawal loses funds — crypto-withdrawal-time and network selection double-check.

Start small before moving size — one mistaken address is irreversible.

Multisig optional for large holdings — complexity tradeoff vs single-sig hardware.
