Help spread awareness for build reproducibility
Please help us spread the word discussing the risks of centralized custodians with Coinme: Buy Bitcoin With Cash 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 ¶
The app is described as an on-ramp and off-ramp bitcoin and cash exchange. It allows users to receive, store and send Bitcoin. It is also possible to sell bitcoins and pick-up the cash from several locations. Security-wise, it claims:
Assets are secured with industry-leading, bank-level security. Your account requires mobile phone 2FA. Sophisticated anti-fraud analysis tools are employed to monitor for any suspicious activity.

What is Coinme?
Coinme is a licensed and regulated digital currency exchange and wallet provider. That means we help everyday people get access to bitcoin and cryptocurrency. Coinme powers a large network of physical locations where users can buy and sell bitcoin with cash.
7.1 Private Keys; Storage of Tokens. Coinme will retain the private keys for any Tokens in the Hosted Wallet, for which private keys are necessary in order to transfer any Tokens out of the Hosted Wallet. Coinme will use the private keys in order to affect the transfers initiated using your Coinme Account. Tokens shown as being held in your Hosted Wallet may be in the Hosted Wallet based on internal ledgers and records maintained by Coinme, but customer Tokens may be held in pooled accounts controlled by Coinme on the public distributed ledger for the applicable Token (“Blockchain”).
Section 7.1 of Coinme’s Terms and Conditions strongly points to a custodial service that’s 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.
