Ratings and reviews

the app isn't showing in any noticeable way that your premium trial 7 days starts, and after it the basic functionality of a multisig (send transaction) will evaporate, and you end up buying their lvl 1 premium, for like $70. But after it the app says, that it still doesn't work, and you need a lvl 2 for like $300 because you have 3+ signers in the multisig. I ended up writing a custom script, which generated a transaction, working with their contract, to move my funds away from this scammers.

Seriously dude? I transferred £100.00 of BTC to my wallet from Coinbase Pro, and tried to transfer it to an external wallet using MultiSig, but was forced to pay a subscription (£45.19) in order to do so. This is totally not cool, you should've warned me my crypto would be trapped without a membership! I would be willing to change my review to a 3–4 star if you'd be willing to turn me from a pissed off, deceived customer to a happy customer, because other than this, the product seems great!

Love this app but I shouldnt be having syncing issues considering it's a paid subscription. When I receive deposits of certain coins such as ADA, the amount is reflected in TX history and coin has 200+ confirmations yet the balance is unavailable to transact. The delay of wallet to catch up with chain is ridiculous.
