Mnemonic Code Converter

Mnemonic

You can enter an existing BIP39 mnemonic, or generate a new random one. Typing your own twelve words will probably not work how you expect, since the words require a particular structure (the last word is a checksum)

For more info see the BIP39 spec

Derivation Path


For more info see the BIP44 spec


For more info see the BIP32 spec

Use path m/0'/0. For more info see the Hive Wallet homepage

Use path m/44'/0'/0'/0. For more info see the Mycelium Wallet homepage

Use path m/0'/0' with hardened addresses. For more info see the Bitcoin Core BIP32 implementation

Use path m/44'/0'/0'. Only enter the xpub extended key into block explorer search fields, never the xpriv key.

Derived Addresses

Note these addreses are derived from the BIP32 Extended Key

Private Keys
