[coinb.in] Open Source, Multi Signature, HD Wallet, SegWit/Bech32 and more!

I agree.

I suggest to use recommended fee instead if change amount as fee and as this is advanced software, please allow users to edit transaction fee. You can send change back to origin address like xDan told.

The problem is not everyone would be happy with the funds being sent back to their original address, also its possible to populate the "inputs" on a new transaction with funds from multiple addresses. There is a few things to think about, because I don't want to force users to do anything they don't want to. But a confirmation notice sounds ok..

Ok. As it is aimed on advanced users, shouldn't we be able to set custom fee? Currently, I can't do it. Please change it.

The transaction fee can be manipulated by adding another address, this can either be the address you populated the unspent funds from, or an entirely new address if you have privacy concerns.

Am I miss understanding something?

No, you understood correctly and I understood wrongly. Keep up the good work.

Btw, was this newly added? If yes, is there an archive to download older version? Thank you!

People, try to understand first how MultiSig works in standard wallet, than use such great tool as coinb.in.

[xDan]

Hey,

>I will take into consideration what you've said and perhaps throw up a confirmation notice if the fee is too large.
Great! Warnings and sane defaults are good

>But please keep in mind this is the first time someone has mentioned this and made such a big issue about it
Most skilled tech people aren't much concerned or knowledgeable about the experiences of newbies, certainly. And maybe they have great confidence and don't believe they themselves can ever make a mistake when in a rush. But it happens to the best of us.

I think lots of fairly inexperienced Bitcoiners have paper wallets, for which this sort of thing is very useful. Previously I've used offlinewallet.appspot.com , which isn't maintained any more I don't think, so your site is a good alternative.

It's great work otherwise. I just hate to see people lose money accidentally. What with Bitcoin Core's private key pool and out of date backups, change addresses that existed only temporarily in LiveCDs, and mistyped transaction fee amounts, people have lost large amounts for entirely stupid and preventable reasons, and reading their stories is always quite heartbreaking

Stumbled across this youtube tutorial by Alex Millar for using multisig at coinb.in. (also added it to the original post)

Thanks Alex.

[OutCast3k]

So I've been working (very) slowly on this section for the past few weeks.

https://coinb.in/#settings

The idea is to make it easier to retrieve your inputs for a transaction and broadcast a transaction via coinb.in or a number of other third parties, as well as making it easier to use bitcoin testnet (and eventually altcoins).

At the time of posting this, I have only added multiple hosts to broadcasts too, and have not yet added any services to retrieve your inputs for a transaction.

Once complete though this should make coinb.in even more resilient and decentralized than most wallets.

Feedback and suggestions are welcome.

So, as far as I know, there are no wallets/services that allow for Trezor+multsig (well, there's Greenaddress, but that uses their servers to do stuff).

Any chance Coinbin could be the first to do this?

It will be even very useful if it's possible to do the same with Coinbin as do this version of electrum:
https://github.com/greenaddress/electrum/tree/greenaddress-2of3-recovery

Being able to recover a 2of3 wallet from an offline Greenaddress with Coinbin

This awesome project Open Source, Multi Signature and HD Wallet, though I have paid for a hardware cold wallet but when needed I will surely download and try this fantastic project of yours.
Thank you for sharing.

Can you modify the byte limit for OP_RETURN 80 bytes?

[OutCast3k]

Can you modify the byte limit for OP_RETURN 80 bytes?

Sure, I have a few changes to make. I'll allow it to accept 80 bytes but still recommend that you keep it at 40.

So, a quick question to the community!

Not many people seem to be donating and I need to generate enough to at least pay for the VPS. I don't want to add advertising to the site, although Google ads would probably generate me quite a bit. Does anyone have any suggestions for generating donations? I suppose I could make it optional on the new transaction page to donate, or throw up a message now and again.

What do you all think would be least intrusive?

How much are you paying per month?

You might also host your site on Github for free.

How much money are we talking about here? Give us a donation target

While signing a multisig transaction, does the order of signing it matters ?

Is this order  linked to order of public keys used to create that multisig address ?

There is no "specific" order when signing.

Its about 25£ a month. Its UK hosted, so probably a bit more expensive than usual. I can't run it from github as I need to be running a Bitcoin client, sometimes multiple ones.
