Zipwallet-Bitcoin & Send moneyLatest release: 69 ( 5th September 2021 ) 🔍 Last analysed 6th October 2021 . Custodial: The provider holds the keys Not functioning anymore
As the provider of this product holds the keys, verifiability of the product is not relevant to the security of the funds!
As part of our Methodology, we ask:
Is the product self-custodial?If the answer is "no", we mark it as "Custodial: The provider holds the keys".
A custodial service is a service where the funds are held by a third party like the provider. The custodial service can at any point steal all the funds of all the users at their discretion. Our investigations stop there.
Some services might claim their setup is super secure, that they don’t actually have access to the funds, or that the access is shared between multiple parties. For our evaluation of it being a wallet, these details are irrelevant. They might be a trustworthy Bitcoin bank and they might be a better fit for certain users than being your own bank but our investigation still stops there as we are only interested in wallets.
Products that claim to be non-custodial but feature custodial accounts without very clearly marking those as custodial are also considered “custodial” as a whole to avoid misguiding users that follow our assessment.
This verdict means that the provider might or might not publish source code and maybe it is even possible to reproduce the build from the source code but as it is custodial, the provider already has control over the funds, so it is not a wallet where you would be in exclusive control of your funds.
We have to acknowledge that a huge majority of Bitcoiners are currently using custodial Bitcoin banks. If you do, please:
- Do your own research if the provider is trust-worthy!
- Check if you know at least enough about them so you can sue them when you have to!
- Check if the provider is under a jurisdiction that will allow them to release your funds when you need them?
- Check if the provider is taking security measures proportional to the amount of funds secured? If they have a million users and don’t use cold storage, that hot wallet is a million times more valuable for hackers to attack. A million times more effort will be taken by hackers to infiltrate their security systems.
But we also ask:
Is the product still supported by the still existing provider?If the answer is "no", we mark it as "Not functioning anymore".
Discontinued products or worse, products of providers that are not active anymore, are problematic, especially if they were not formerly reproducible and well audited to be self-custodial following open standards. If the provider hasn’t answered inquiries for a year but their server is still running or similar circumstances might get this verdict, too.
Do your own research!
Try out searching for "lost bitcoins", "stole my money" or "scammers" together with the wallet's name, even if you think the wallet is generally trustworthy. For all the bigger wallets you will find accusations. Make sure you understand why they were made and if you are comfortable with the provider's reaction.
The Analysis ¶
Update 2021-09-28: This app is not on the Store anymore.
(Analysis from Android review)
##Google Play Critical reviews
★☆☆☆☆ Februaru 26, 2021
This app is very poor. I can’t send bitcoin because it keeps crashing when I press the send button. Also on different device it says insufficient funds not matter how much, or how little you send so you can’t do anything. Very poor. And why you can’t use same functionality on web, at least to mitigate the shortcomings of the app. Now my bitcoin is sitting there losing value cause I can’t send it.
Its homepage description reads:
Simple exchange platform with over 300 payment providers around the world.
Universal solutions for fund exchange between payments providers.
We downloaded the app and was able to locate the BTC wallet. However, the private keys nor the mnemonic seed phrases were both not readily apparent. It seems to be a fiat/voucher/gift card balance to bitcoin exchange and vice versa.
When we tried to share our BTC address from the wallet, no QR code was generated and the BTC address would only appear visually once it has already been shared to the receiving party.
A huge chunk of its short User Agreement is focused on prohibited entities including businesses.
As there is a capability to send and receive Bitcoins with an entity that has the power to that , we determine this app to be custodial and thus, not verifiable.
