Wallet Mnemonics: A Comparative Analysis

Wallet mnemonics are crucial components of cryptocurrency wallets, providing a secure and convenient way to recover funds in case of device loss or damage. Composed of a set of random words, they serve as a backup of the private keys that control access to crypto assets.

Types of Wallet Mnemonics:

• BIP39: The most widely used mnemonic standard, BIP39 generates 12 or 24 unique words from a dictionary of 2048 words. It provides a balance of security and memorability.
• BIP44: An extension of BIP39, BIP44 introduces a hierarchical deterministic (HD) wallet structure enabling the generation of multiple addresses from a single mnemonic. This enhances privacy and security.
• BIP49: Similar to BIP44, BIP49 defines a specific HD structure used for generating SegWit addresses. It offers enhanced security and efficiency for SegWit transactions.
• BIP84: Designed for native SegWit wallets, BIP84 specifies a unique HD structure for generating native SegWit addresses. It provides improved security and a more streamlined transaction process.

Generating and Storing Wallet Mnemonics:

• Always use an official wallet software or hardware device to generate wallet mnemonics.
• Generate mnemonics offline, isolating them from any online vulnerabilities.
• Write down the mnemonic phrase on a physical, tamper-resistant medium such as paper or metal plates.
• Avoid storing mnemonics digitally or in unencrypted form.

Safeguarding Wallet Mnemonics:

• Divide the mnemonic phrase into multiple parts and store them in separate locations.
• Create a decoy mnemonic phrase or passphrase to misdirect potential attackers.
• Implement two-factor authentication (2FA) or other security measures to protect your wallet accounts.

Wallet Mnemonic Comparison:

Standard	Word Count	HD Structure	Usage
BIP39	12, 18, 24	No	Standard mnemonic
BIP44	12-24	Yes	HD wallet
BIP49	12, 18, 24	Yes	SegWit HD wallet
BIP84	12, 18, 24	Yes	Native SegWit HD wallet
