Help spread awareness for build reproducibility
Please help us spread the word discussing the risks of centralized custodians with TRASTRA: Crypto Wallet & Card via their Twitter!
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 2022-02-26: This app is not available anymore.
(Analysis from Android review)
While this might be a good thing:
- External Custodians are usually highly specialized in securing assets
- External Custodians will care about fixing issues with one client, to not lose others
- External Custodians are usually registered businesses under regulatory oversight
- External Custodians will try to protect your funds even from your wallet provider: With fraud detection, they will certainly try to avoid the emptying of all users' wallets at once
- External Custodians are extra intermediaries: Even when the wallet provider wants to let you use your money, they might turn out to be uncooperative
- External Custodians holding custody of many wallets are interesting targets for hackers and thieves
- External Custodians, being publicly registered will not be able to resist if in their jurisdiction rules on the use of Bitcoin get tightened
As External Custodians usually don't publish lists of companies they are working with and past information might be outdated, we have no way of assuring claims by wallet providers to be using their custody solution. Please let us know if you found proof that the provider is being dishonest about their business relation to External Custodians!

In its user agreement, it states under the heading “The Services” that:
On our Website, we arrange provision of the Wallet and the payment Card, facilitated by our partner(s), in order you could buy, sell and manage supported cryptocurrencies, as well as apply for, manage and load money onto a Trastra payment card.
Bitgo is the third party provider.
All indications by far indicate that this is a custodial service and therefore not verifiable.
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 not, we tag it Custodial!
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 not, we tag it Defunct!
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.
