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 contains a checksum).

For more info see the BIP39 spec.

If you share the information generated by this page with anyone, they can steal your assets. Anyone asking you to share your your secret recovery phrase or BIP 32 root key is a scammer. Do NOT copy & paste information from this page or send it to anyone offering to help you on Twitter, Discord, Telegram, Etherscan, or Line. They will steal your coins.

Derivation Path


For more info see the BIP44 spec.

The account extended keys can be used for importing to most BIP44 compatible wallets, such as mycelium or electrum.

The BIP32 derivation path and extended keys are the basis for the derived addresses.


For more info see the BIP32 spec

Use path m/0'/0' with hardened addresses.

For more info see the Bitcoin Core BIP32 implementation

Use path m/0'/0. For change addresses use path m/0'/1.

For more info see MultiBit HD

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

Can be used with: blockchain.info


For more info see the BIP49 spec.

The account extended keys can be used for importing to most BIP49 compatible wallets.

The BIP32 derivation path and extended keys are the basis for the derived addresses.


For more info see the BIP141 spec


For more info see the BIP84 spec.

The account extended keys can be used for importing to most BIP84 compatible wallets.

The BIP32 derivation path and extended keys are the basis for the derived addresses.

Derived Addresses

Note these addresses are derived from the BIP32 Extended Key

Enabling BIP38 means each key will take several minutes to generate.
