OK, guys.

Thank you all for your responses.

I will go with an Electrum. Seems quite easy

Hi,

I am looking for some reliable wallet service / application with multisig possibility.

Me & my friend are about to start a small business
We want to create a secured wallet so that none of us independently can spend the money, ie to spend the money we have to put 2 signatures ( his & mine ).

I know that it's possible, but at the same time, I don't want to use things like Bitcoin Core.
So I am searching for more UX friendly alternatives and, of course, reliable ones.

Are there anything you can suggest?

Thank you in advance.

Best Regards,

OK, thank you.

Hi there,

Hope you can clarify an issue regarding Transaction Malleability for me.

Lets suppose I will issue a transaction with a hash 1111 , then someone utilises transaction malleability and changes my transaction, so it will have a new hash: 222.
As far as I understand, only 1 of these 2 transactions will be eventually confirmed in the blockchain.
The question is: will the second transaction become conflicted one with the confirmations value equal to -1, according to this API docs:

Thank you in advance.
