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.

Generate a random mnemonic, or enter your own below: words

Derivation Path


For more info see the BIP44 spec.

The account extendend 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/44'/0'/0'. Only enter the xpub extended key into block explorer search fields, never the xprv key.

Can be used with: blockchain.info


Derived Addresses

Note these addreses are derived from the BIP32 Extended Key

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 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 steet address, keyboard mashing, or anything you think is random, because chances are overwhelming it isn't random enough for the needs of this tool.

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.
