A JavaScript library implementing Bitcoin BIP39 mnemonic code for generating deterministic keys from entropy. It supports multiple language wordlists and converts between entropy, mnemonic phrases, and seeds.
Use cases
- generate a BIP39 mnemonic seed phrase in JavaScript
- convert entropy to a mnemonic phrase
- recover a wallet from a 12 or 24 word recovery phrase
- validate mnemonic checksums in a crypto wallet app
- generate deterministic keys from a seed phrase
- support multilingual BIP39 wordlists in a wallet
When to choose
- building a Bitcoin or cryptocurrency wallet in JavaScript or TypeScript
- you need standards-compliant BIP39 mnemonic generation and validation
- you want to bundle only specific language wordlists to keep bundles small
When to avoid
- you need full wallet functionality like key derivation or transaction signing (use a broader wallet library)
- your project is not JavaScript/Node.js based
- you need BIP32/BIP44 hierarchical derivation, which this library does not provide
