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. -

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

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

-

- Use path m/0'/0. -

-

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

Derived Addresses

-

Note these addresses are derived from the BIP32 Extended Key

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

Private Keys

-

- - Use private keys at - brainwallet.org. - - Be careful - it can be easy to make mistakes if you don't know what you're doing. -

-

Entropy

-

- Entropy values should not include the BIP39 checksum. This is automatically added by the tool. -

-

- - Entropy values must be sourced from a - strong source of randomness. - - This means flipping a fair coin, rolling a fair dice, noise measurements etc. - - Do NOT use phrases from books, lyrics from songs, your birthday or street address, - keyboard mashing, or anything you think is random, because chances are overwhelming it isn't - random enough for the needs of this tool. - -

-

- Do not store entropy. -

-

- Storing entropy (such as keeping a deck of cards in a specific shuffled order) is unreliable compared to storing a mnemonic. - Instead of storing entropy, store the mnemonic generated from the entropy. - Steganography may be beneficial when storing the mnemonic. -

-

- - The random mnemonic generator on this page uses a - cryptographically secure random number generator. - - The built in random generator can generally be trusted more than your own intuition about randomness. - If cryptographic randomness isn't available in your browser, this page will show a warning and the generate button will not work. - In that case you might choose to use your own source of entropy. -

-

- You are not a good source of entropy. -
