As part of our Methodology, we ask:
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.
The Analysis ¶
This does not represent a full code review.
OMPfinex is a trading platform which also advertises “demo capability.” This app offers a web version here.
It is capable of restricting services from any offending users:
- Authentication in OMPFinex is necessary and users are required to upload their correct and complete details, and in case of user abuse, OMPFinex can stop its services for the offending user and report violations to the competent authorities.
From the homepage:
Register with OMPFinex right now and buy instant digital currency sales. Note that to buy and sell digital currency in the main market, you need to complete your authentication; But the possibility of buying and selling in the demo (trial) market will be possible immediately.
Here is what the page says on security:
One of the major concerns of OMPFinex is the security of users’ assets. OMPFinex keeps all its assets in a cold wallet for the security of its customers’ assets. In cold wallets, the possibility of hacking users’ wallets is almost zero.
As the providers claim to keep the customers’ assets in a cold wallet, it’s unlikely that the user holds the private keys. We can conclude this is a custodial wallet.

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.
If you find something we should include, you can create an issue or edit this analysis yourself and create a merge request for your changes.
