Does anyone has experience in multisignatur wallets like copay for escrow service?
Not in escrow service (though that is a brilliant idea) but I have been using copay for a while and have couple of wallets in it, one of which is a multisig 2of2 and it is as easy as 123 and could be used as multisig escrow service for sure.
I've create a multisig wallet with electrum once... only to test it out myself tough... Worked like a charm
I don't remember which tutorial i followed, but a quick google found this one:
https://www.deepdotweb.com/2015/03/21/multi-signature-transactions-electrum-2-0/ Altough i haven't used this tutorial, it looks about right... If i remember correctly, those were the steps i took myself to test electrum multisig.
Ahem.. OP is asking of Copay multisig wallet and if that can be used for multisig escrows, not for electrum one.
copay wallet service down?
No it's not, I just made some bets using it.
