Hi

I'm tired of the constant bugs with my desctop wallet (multibit), but i do not trust online wallets.

So I developed "semioffline" javascript wallet https://multicoins.org
Main feature: all private keys are stored in the browser cache (but may by encoded and then backuped on the server).

Other features:
- Support Bitcoin, Litecoin, Dogecoin, Peercoin and Bitcoin-testnet
- View balance and push transactions. Multiple outputs is available
- Generate new key pairs
- Import private keys
- Sign/Verify messages
- Encode/Decode wallet
- Backup/Restore wallet

Service in active development. I would be grateful for any suggestions!

Source code: https://github.com/3s3s/multicoins.org

Updates:
03.19.2016 Add Dogecoins
04.08.2016 Add support for multiple outputs
04.21.2016 Add support for Peercoins

if private key is saved in users browser cache than if we clean cache than we will lost our access to coin?  ???

i guess you right  ???

Hi,

you can use backup feature to gain access to your wallet at any time from anywhere :)

see at:         Security -> Backup/Restore wallet

For tests you can use my private testnet key: cPtyQjUSvdkWV2ahPVtKajHEhARc2BavfaokHwXPaoGMdmKMP4gT

Good to see that there is new initiative in the wallets field. But don't you think that market is quite saturated with good products already?
It will be really hard to develop wallet with good functionality, design and on top on that - trustworthy and reliable.

Do you have time, resources and dedication needed to taking care of this project?

As I already said, first of all this project I need to for my purposes. I am an active bitcoin user, but I am quite disappointed functionality of existing wallets like multibit and core.
It will be great if my project is interested in someone else. But in any case, i'll continue to work on it.

So, it's kind of like blockchain.info, but for multiple coins? I'm interested. Keep up the good work!

I believe it's only for Bitcoin/LTC and Testnet addresses (stated on the website itself), but the main feature here is that the private key is stored in your browser cache and not the website itself (although I might be wrong that it's not stored on the website itself; I'm not entirely sure how it works).

If it's not stored in the website itself, then this is a great "online" wallet (I know you referred to it as a semi-offline/online wallet, but I think that might require more proof that the private keys aren't stored on the website?).

so site just generate bitcoin address and private key with java and then store that in session cookie in browser which than will be used to do transactions?

Than i think you can also add lots of other coin in your site in this way.

Hi, thanks for the feedback !


Yes that's right. And yes, main feature here is that the private key is stored in browser cache and not the website itself. Blockchain.info and other "online-wallets" do not allow private keys and store them in their servers.

Soon the source code will be available on the GitHub.  Right now you can see the source code by using browser tools.


Yes, I plan to add support more forks in the future.

I'm looking forward for the development of this wallet.It looks very promising with new concept? Since this is still in developing phase,keep us updated here. Clean site interface but looks like there are missing menus and its still under construction,right? Keep up the good work,Good Luck.

i think there is no harm to trying this service  :D

just try  :D

Nice to see someone working on a potential new good wallet. Would be nice if there will be more coins supported.

The source code is now available https://github.com/3s3s/multicoins.org

Update interface:
1. Add total balance
2. Add spinners and change some alerts.

Add DOGE coins!

Multicoin wallets make life a lot easier... how is it that is semi-offline? what does that mean exactly? Which is the offline part?

Offline it makes:
1. generate public and private keys
2. import private keys
3. encode/decode wallet
4. sign/verify messages
5. store private keys

Online it makes:
1. receives address balance
2. obtains a list of transactions
3. push raw transaction
4. backup/restore encoded wallet

Add support for multiple outputs
