I'm trying to do something like: unspent A1 + unspent A2 + unspent B ~> output C
can someone tell me how to sign raw tx made of 3 inputs from 2 different address?
I can create the unsigned raw transaction but when signing only one address works at a time
I cannot make all inputs signed properly, is it possible to do that with coinb.in?
or what is the correct procedure to create signed raw tx from 2 different address?

If I understand the code correctly, you will have to do one address at a time.

 unspent A1 + unspent A2 ~> output C

then

 unspent B ~> output C

then

 unspent B ~> output C

that means I have to create 2 separate transactions, right?
anyway to make it into single transaction just like if we use bitcoin wallet?
I was hoping some setting with "Sig Hash Type" options on "Sign" tab could solve it
but I cannot understand how to make out of it (use of those different sighash types)
the two sighash types that I think might help my case:

SIGHASH_NONE: Signs all of the inputs but none of the outputs, allowing anyone to change where the satoshis are going unless other signatures using other signature hash flags protect the outputs.
SIGHASH_NONE|SIGHASH_ANYONECANPAY: Signs only this one input and allows anyone to add or remove other inputs or outputs, so anyone who gets a copy of this input can spend it however they'd like.

[Thirdspace]

OK... I think I figure out how to do what I'm trying to do
I just sign with privkey A to get partially signed raw tx
then I sign again "that partial signed raw tx" using privkey B
that give me all inputs signed properly (all inputs checked under signed column)

I haven't try broadcast it yet, fear of losing my BTC because of misconstructed signed raw tx
I hope OutCast3k would stop by and confirm on how to do this
and perhaps he or someone could also explain & give condition/example to
the usage of all those 5 non-default sighash types, thanks!

just wondering since coinb.in is for developers for testing - can it be used to test without btc or dodge in the address?  i would like to do some testing but rather not use real btc for general testing - this reddit seems to imply testing may infact be possible
https://www.reddit.com/r/dogeducation/comments/6eowvb/can_anyone_tell_me_how_to_use_coinbin/?ref=share&ref_source=link
but both the local javascript page and the live https://coinb.in/#txinputs return errors for addresses that have no coins.

also - am i incorrect in understanding that coinb.in can be used locally in an airgap situation to create transactions or must it be able to connect to generate transactions as i remember OutCast3 mentioned in a discussion on a bounty site....tho that may have been regarding an old pull requesst....

If you use the version at coinb.in, just go the the broadcast page, on the right side is a little icon that you can click, you can select the bitcoin test network there.

for newbies to coinb.in it must be online to send a transaction

@Pente i did find the testnet setting @ coinb.in/#broadcast the small blue gear symbol.


1)I changed settings to bitcoin(testnet), Broadcast: coinb.in (Bitcoin mainnet), Unspent outputs: coinb.in (Bitcoin mainnet)
2)created new send and recieve addresses
3)clicked Transaction to create a new transaction
   Address, WIF key or Redeem Script: area is greyed out so no inputs are possible
4)enter two recieve addresses with amounts into outputs tab
   Outputs (2.3000000) total is added for both recieve addresses
5)clicked Inputs tab
      Address, WIF key or Redeem Script: area is greyed out so no inputs are possible
6)enter input address into Transaction ID: field and fill in amount = Outputs (2.3000) + Transaction Fee
   Transacton fee: section is automatically filled in
ERROR: One or more input or output is invalid
7)enter input Public key (Share) into Transaction ID: field and fill in amount = Outputs (2.3000) + Transaction Fee
   Transacton fee: section is automatically filled in
submit
ERROR: One or more input or output is invalid
I will not post redundant steps but all combinations of Address (Share), Public key (Share), Private key (WIF key) generate
submit
ERROR: One or more input or output is invalid

can someone clarify (provide example or steps) to create a BCC BitcoinCash TEST transaction.  The systems apparently works for live transactions but i wish to use testnet with fake transactions for testing.  thank you much for help figuring this out if it can be done.

Ok, it looks like coinb.in doesn't actually get inputs (or even broadcast) from testnet. That section of code is incomplete. Also no testnet for BCC. Transactions are cheap enough on BCC, that you don't really need testnet. Just use a few pennies worth of BCC to test.

Throughout the year, there are lots of projects I've been hearing about, and many people in the bitcoin community are really psyched about it. However, they do not understand that one must be responsible and hard working for him or her to exell.

I noticed one more thing just now,
I tried to sign an unsigned raw tx at different times, it resulted exactly the same signed raw tx every time
shouldn't I get different signed raw tx every time I do it, because of hashes thingy
if the signed raw tx the same, doesn't it mean it uses the same seeder(?) every time
I might have use some terms incorrectly, but you probably get what I mean

I think I saw the same problem once, but later I didn't see it. Maybe I will investigate it some more.

In the meantime, I would suggest not reusing the P2SH address, since it does mean the private key could be compromised.

Interesting
What do you mean - "HD Wallet"??

Can we move Bitcoin Cash and Bitcoin Gold using Coinbin?

You can create Bitcoin Cash P2SH transactions here: http://www.motelmaya.com/BCC/BCC.html

We don't know if Bitcoin Gold is using replay protection yet. If it does, it will probably mess up P2SH transactions just like Bitcoin Cash did. Hopefully, we can figure out a way to recover those coins if that happens.

I think we will get lucky on the SegWit1X/SegWit2X fork though. Seems like they learned about the severe problems with replay protection and don't want to repeat them.

Do u mean, if I had BTC on a multi-sig address before the BCC fork, I wont be able to recover those BCC now?

Please check the BTC/BTG/BCH/B2X Comparison on http://btcgpu.org. It mentions Replay protection for BTG.

If the project need translation for either Arabic or French, feel free to let me know. I could do it. (or make a translation page at Transifex)

What is this Motel Maya?

It's a Coinbin clone that works for Bitcoin Cash. I used it to claim some BCH from an old Time-Locked Address I had and it worked.

Please check the BTC/BTG/BCH/B2X Comparison on http://btcgpu.org. It mentions Replay protection for BTG.

They stated that they will have replay protection for the fork. But AFAIK it isn't implemented yet and they released a bounty 5 days ago to get this done. So it's not confirmed yet.

Hello Dev,

Is this working with BTG ADDRESS to see the balance?

Thanks
