Read the first 7 Wallets and Asset Security flashcards as text

  1. What is a 'stealth address' in cryptocurrency privacy?

    Answer: A one-time address generated by the sender so only the recipient can detect incoming funds

    Stealth addresses use the recipient's public key to generate a unique one-time address per transaction that only the recipient can scan and spend from.

  2. What does 'SLIP-0039' define in the context of hardware wallets?

    Answer: Shamir's Secret Sharing for mnemonic backup

    SLIP-0039 (used by Trezor's Shamir Backup) standardizes how a BIP-39 seed can be split into multiple shares using Shamir's Secret Sharing.

  3. Which scenario best illustrates a 'SIM swap' attack targeting a crypto user?

    Answer: An attacker convinces a carrier to transfer the victim's phone number to a new SIM, intercepting SMS 2FA codes

    SIM swapping involves social-engineering a mobile carrier to reassign the victim's number, giving the attacker control of SMS-based 2FA and account recovery.

  4. What is the purpose of 'PSBT' (Partially Signed Bitcoin Transaction)?

    Answer: A format that allows offline devices to contribute signatures before broadcasting

    PSBT (BIP-174) is a standardized format for passing an unsigned or partially-signed transaction between devices (e.g., hot and cold wallets) to collect signatures before broadcasting.

  5. Why should users verify the receive address displayed on a hardware wallet's screen rather than trusting the host computer's display?

    Answer: Host software may show a different address injected by malware

    Malware on the host computer can replace the displayed address with the attacker's; the hardware wallet's trusted screen shows the genuine address.

  6. What distinguishes 'custodial' from 'non-custodial' wallets in terms of security responsibility?

    Answer: With custodial wallets, a third party controls the private keys; with non-custodial, the user does

    In a custodial wallet, the service provider holds the private keys, meaning users rely on that party's security; non-custodial wallets give users sole key control.

  7. Which metal backup option provides the strongest resistance to physical destruction of a seed phrase?

    Answer: Stainless steel or titanium plates with engraved or stamped seed words

    Metal plates (stainless steel or titanium) withstand fire, water, and physical impact far better than paper, polymer, or electronic storage.
