I was trying over the last few weeks to implement HD wallet (electrum-like).
So far, it works for PPC, LTC, BTC.

USE AT YOUR OWN RISK! IT IS STILL A VERY EARLY ALPHA, ONLY FOR TESTING PURPOSE. NO RESPONSABILITY!
That said, it seems to works well enough for basic case (but many corner cases are maybe not covered well).

A few notes:
  • Full Hierarchical Deterministic wallet with both receiving and change address.
  • It will fetch as many as necessary to have empty ones. Used address will be striked.
  • Sign and send transaction from your browser. It will automatically gather unspent outputs from your various receiving/change addresses.
  • Seed are electrum-compatible. That is, for BTC it should generate same addresses.
  • Client side encryption. Nothing stored on server. Client signs transactions and push them through API. This should help avoid many usual vectors of attacks.
  • Feel free to review the code (security, etc...). Many of the used javascript libraries are known, and the important part is happening in wallet.js.
  • I need to add https. In the meantime it's probably OK, since encryption/signing is javascript client-side only, outside people can't see more than your API address/balance requests.

Testing & feedback welcome! Don't forget, it's a very early release.

Enjoy!

Special thanks to carbonwallet, brainwallet & bip32.

EDIT:
Created a github webpage: https://github.com/bkchain
  • Issues/requests/bug reports go there.
  • As soon as I get around it, that's where I plan to put sources.

The Bitcoin software, network, and concept is called "Bitcoin" with a capitalized "B". Bitcoin currency units are called "bitcoins" with a lowercase "b" -- this is often abbreviated BTC.

Good work so far Smiley

I did have a question for you if you don't mind answering. The blockchain parser you suggested does not provide the data structures for transaction inputs/outputs. Am I missing something here or did you do extra work on that area?
