MemWallet

Try memwallet now

MemWallet is a deterministic cryptocurrency address generator, like WrapWallet, but it works for Ethereum, Litecoin, Monero and Bitcoin. You never have to save or store your private key anywhere. Just pick a really good password - many random words, for example - and never use it for anything else.

Given the same Passphrase and Salt, MemWallet will always generate the same address and private key, so if you only need to remember your password to access your funds.

For more information on why this is safer than a regular brainwallet, see WrapWallet's help, MemWallet is a re-implementation of WarpWallet, but it works for other currencies. WarpWallet and MemWallet use the same algorithm, so WarpWallet and MemWallet will generate the same Bitcoin address for a given Passphrase and salt.

Here is a implementation of MemWallet in JavaScript and Go

memwallet's Issues

Great work! :) - I have some questions about your memwallet

Hi David,

Great job on the memwallet. I've always wanted to figure out how to generate other coins using the warpwallet setup. I'm still learning how this all works and trying to wrap my head around it as I'm not a js ninja like you.

I've been poking around to see how it works. Below is the code that setups the difficulty of the scrypt with Math.pow. My question is does it have to be a Math.pow() ? Why can't you just put any number in there? I tried it with scrypt(), but it throws an error as it needs to be the power of 2. It works for pbkdf2 with any number in there, but I dont understand why it has to be to the 2^N power. Be great if you can explain it.

  scrypt(Buffer.concat([password_buffer, x1]), Buffer.concat([salt_buffer, x1]), Math.pow(2, power), 8, 1, 32, function(error, progress, key1) {
    if(key1) {
      pbkdf2.pbkdf2(Buffer.concat([password_buffer, x2]), Buffer.concat([salt_buffer, x2]), Math.pow(2, 16), 32, 'sha256', function(err, key2) {

Thanks!
