Hello,
I would like to ask if there is any Multisig Wallet standard exists for Aeternity? I would like to purpose if not as I have worked on a smart contract of Multiple Signatures based Pre-sale and tested it in different scenarios with more than 20 tests.
Regards,
@VitalJeevanjot you might want to have a look at this 
we’re working on a simple multisig contract which uses generalized account feature of aeternity. contract code is being audited right now
source:
but that’s not enough, we need a management ui for this which will are about to start working on.
regardless of that @hanssv.chain started working on a musig implementation which allows to perform 2-of-2, 3-of-3 multisig transactions based on schnorr signatures:
it’s not documented yet. not 100% sure about the state and he is currently busy with other things.
for n-of-m (2-of-4) schnorr based multisig we’d need a change in the protocol first.
we know multisig is needed and we’re working on it 
independently of that, feel free to share your code! though I wouldn’t recommend anybody to use multisig contracts which haven’t been carefully audited. we saw how this worked out back then in the Parity horror scenarios which also aeternity suffered from 
Thanks, Erik.
It seems that this post was based on signing a transaction through a single wallet (got from 2 wallets off-chain) and not decisions on contract-based (accept/revoke, x out of y, etc.) transactions.
I completed this work a month ago with sufficient tests to satisfactory results in the end,
well, this horror In this context has nothing to do, because we initialize the contract the moment we deploy. Effectively defining owners and other parameters.
