Understanding BIP39 Mnemonics
BIP39 mnemonics are human-readable phrases (12–24 words) that generate cryptographic seeds for wallet addresses. Key features include:
- Cross-Wallet Compatibility: Works with Ledger, Trezor, MetaMask, and other BIP39-compliant wallets.
- Local Processing: All conversions occur offline in your browser for maximum security.
Custom PBKDF2 Iterations
Note: Using non-standard PBKDF2 iterations may cause address discrepancies across software. Learn more.
Derivation Paths Explained
Supported paths for hierarchical deterministic (HD) wallets:
- BIP32: Base standard for HD wallets.
- BIP44: Multi-account wallets (e.g., Bitcoin, Ethereum).
- BIP49: P2WPKH-nested-in-P2SH (SegWit compatibility).
- BIP84: Native SegWit (Bech32 addresses).
- BIP141: Defines SegWit transaction structure.
Derived Addresses Table
| Path | Address | Public Key | Private Key |
|------------|---------|------------|-------------|
| Example | 1A1... | 03x... | L5z... |
| Example | bc1... | 02y... | K3j... |

Technical Deep Dive
BIP39 Specification
PBKDF2 Iterations
- Default: 2048 iterations.
- Increasing iterations enhances brute-force resistance but requires parameter storage.
Entropy Best Practices
- Source entropy from CSPRNG (e.g., hardware RNG).
- Never store entropy—store the mnemonic instead.
Offline Usage
- Save this page as an HTML file.
- Open it offline via any browser.
