Sparrow Bitcoin Wallet

On my quest to find some new interesting Bitcoin wallets I recently found out about Sparrow Wallet.

It supports single and multisig wallets, as well as importing and exporting Electrum wallets.

It is a beautiful wallet.

I have some mixed feelings about wallets.

I am very satisfied with the wallets I use (software and hardware). They dominate the market somehow

Just like I think oligopolies are bad for everyone, I don't risky trying new wallets.

I trust my money in ledger, trezor and electrum. I wouldn't trust sparrow, at least not with a huge amount. But I could try this wallet for small amounts, if it brings something very new which I would use.

Looks pretty slick— UI looks clean without sacrificing functionality and features.

With that said, I agree with bitmover that I don't think people should use this new wallet for storing keys with high-valued holdings unless you can verify the code and compile it yourself. I'm personally going to wait this out and wait til it gets a bit more publicity.

[mk4]

IMO, it poses no danger to Ledger's keys.

Yeap, not that much risk(as far as I know) since you verify the transaction details on the Ledger device itself anyway. But I was referring to actually using this wallet for generating and actually storing the keys(and not just making transactions like when connecting a hardware wallet to it).

Was going to take a look because I will play a little with anything.
But why are you using Java to build?. A lot, possibly even most security people see java / java script and run screaming in the other direction.

I don't care one way or the other, but you might want to look at another alternative.

Hey Dave
I am not using java or anything, and this is not my wallet project, but I am just testing it because I think it is good that other major wallets have some competition.
We don't want developers to get to lazy, and I like to post something new here in forum so that everyone can explore it. 

Cheers

If this wallet is a scam then I think it is a high level of scammers.
They have some unique features that I've never heard of before, such as:

fully featured transaction editor that also functions as a blockchain explorer. This feature not only allows easy editing of all of a transaction’s fields, (including for example locktime and sequence),

Sparrow is desktop focussed and uses a configuration of Argon2 (winner of the Password Hashing Competition in 2015)


With all this power, the transaction viewer doubles as a private blockchain explorer.

Despite all the details, it is not mentioned how the seeds are managed, the cold storage, and the lightning network.

Generally, I'll give it a try when I have some time.

[dkbit98]

Yes, this transaction viewer acts something like personal explorer, and if you run your own node then you don't need to use any web explorer to check your transactions.
Source code is also open, and anyone can check if it is good, and I would like to see testnet integration, so that more people could try using it with testBTC.

One of the reason for which I would probably download this wallet and give it a try is the possibility to import Electrum wallets. AFAIK, bluewallet is the only wallet that supports importing electrum seeds.
More users will be interested in using it if they release a mobile version.
I agree with posts above, it too early to trust them with our coins as it's still relatively new and we are not sure how secure it is.

Is this wallet opensource?

[Hippocrypto]

Have you tried this running on windows? I am curious on this one because of security issues that might take place in the future. Hopefully you'll have some feedback on this, need some inputs from your end before am going to install sparrow wallet on my pc.

Yes. It's already mentioned & OP mention github link for the source code.

Someone make a blog about this wallet at https://www.bitcoinqna.com/post/sparrow-wallet-101, but there's no mention OS used.
But since this wallet is initially released less than a year ago and the version is below 1.0 (assuming the creator follow proper software versioning), i wouldn't recommend it to store big amount of Bitcoin.

I did install it on my OS for testing purposes and yes it is open source Apache license.

Developers are active on github and twitter, and they often release updates and fixes (latest is 0.9.7) and this wallet can be useful only if you are running your own node.

On my quest to find some new interesting Bitcoin wallets I recently found out about Sparrow Wallet.

It looks nice.
Although I am so much used to Electrum I find it a bit hard to change (maybe I'm getting old?), I already planned to take a look to Wasabi.
Now I've added Sparrow too to my list. I'll give it a try during the Xmas holidays when I should have more (too much?) free time.

It's however nice to see competition coming in this area. I've got sick and tired to "preach" that wallets should become nicer and easier (more newbie friendly) without losing functionality.

Interesting new 1.5.0-beta1 beta update for Sparrow wallet introducing some big changes with coinjoin integration working only on testnet currently.
I was playing around with Sparrow for some time, and I have to say that like it more and more, interface is great and this could soon be better alternative for Wasabi wallet.

Ah, screw it.  I'm going to give it a try.  I must have missed this thread when it was started--or ignored it entirely--but I'm glad you bumped it, dkbit98.  Electrum will probably remain my go-to wallet, but it's been a long time since I played around with a new one.

10 minutes later:  I just set it up, and it looks and feels very nice as a wallet!  I was able to create a wallet with legacy addresses, which you can't do with Electrum anymore, so that's a plus.  Haven't sent any coins to it yet, but I'll bump this thread if anything odd pops up as far as issues go.

I love their initial setup with explanations and easy process for users of choosing connection with bitcoin core node, private electrum node or public server.
Tor support is great and as for coinjoin transactiuons, I didn't test it yet but I plan to do it this weekend when I have more free time.
There are still some issues reported on github and I have no idea how to remove or hide hardware wallet connection after you make it, so I had to delete wallet file and create new one for testing.

Ohoo, I've checked 1.1.0 at some point and I was pretty much disappointed back then, now it's 1.5.0...

I see it does work with my HW now (although the first server I've tried said it has no transactions at all; the second worked). The old version didn't have neither the USB button, nor Ledger on the list of wallets to import.
I see it has things better done than Electrum (View->Hide Empy Used Addresses).
But - at least for me - it still doesn't have the usability of Electrum.
However, it's on the right track, so we'll get there too, and possibly pretty soon.

Thanks @dkbit98 for the update!
