ChainATM vs Tangem
How does ChainATM compare to a hardware wallet? Here's an honest side-by-side.
What Tangem is
Tangem makes card-shaped hardware wallets that hold keys in a secure element and are tapped against a phone by NFC instead of being cabled to a computer.
These are not competing products, they are two layers. Tangem is cold storage: the private keys never leave the device, and every transaction costs you physical access to it. ChainATM is a hot wallet for the everyday loop of buying, swapping and sending. Running both is the normal arrangement, not a compromise.
Common questions
Is Tangem or ChainATM better for buying and sending crypto?
It depends on which part you do most. Pick Tangem if what your use case turns on is what it is strongest at: No cable, no battery, no charging; Backup cards instead of a written seed phrase. ChainATM is the better choice if you want to buy, swap and send from one conversation instead of three separate flows. ChainATM adds no fee or markup of its own. Network, provider and bridge costs still apply. Some are built into the quoted amount rather than listed separately, so check what you pay and what you receive before you confirm. ChainATM does not operate an omnibus customer wallet or hold crypto on its own balance sheet. The default embedded wallet is provided by Privy. After you confirm a supported action, execution may use ChainATM's authenticated backend and Privy's wallet infrastructure, or request approval from a connected external wallet, depending on the route. A card or bank purchase is processed by the third-party provider shown in the app.
What does Tangem cost compared to ChainATM?
Tangem: One-off card purchase; partner fees apply to buys and swaps inside the app. ChainATM: each message you send to the AI in chat uses 1 credit (from about EUR 0.08 per credit with the 500-credit pack), and a buy, swap or send itself uses no credits. ChainATM adds no fee or markup of its own. Network, provider and bridge costs still apply. Some are built into the quoted amount rather than listed separately, so check what you pay and what you receive before you confirm.
Can I use Tangem and ChainATM together?
Yes, and that is the intended arrangement. Large holdings stay in cold storage on the Tangem device; the balance you actually spend each week lives in ChainATM. Both are self-custody, so there is no provider in between who has to approve the pairing.
Does ChainATM hold my crypto like Tangem does?
No. Neither product holds your crypto: Tangem and ChainATM are both self-custody. The difference is the interface, not the custody model. ChainATM is driven by plain-language text or voice rather than by forms, and we never have access to your keys in usable form.
Is ChainATM available in my country?
Availability depends on our on-ramp partners' supported regions. ChainATM is built by Noctra Labs UG (haftungsbeschränkt) in Trier, Germany, registered at Amtsgericht Wittlich under HRB 48033. Card or bank purchases run through a third-party provider shown in the app; payment methods depend on that provider and your region.

When Tangem is the better choice

When ChainATM is the better choice
ChainATM is the better fit for the part a hardware device makes awkward: buying, swapping and sending several times a week. For storing a large balance long term, the device is still the safer place, and that does not change.
Why Choose ChainATM Over Tangem?
Built for the everyday half
Tangem is where a balance should sit long term. ChainATM is for the part that happens weekly: buying, swapping, sending. Neither replaces the other.
No device, no cable, no companion app
Every Tangem transaction needs the device in your hand and its companion software. ChainATM runs from a phone or browser with biometric confirmation.
Fiat onramp built in
Tangem routes fiat purchases to third-party providers when it offers them at all. ChainATM buys with card, Apple Pay or SEPA through Coinbase. ChainATM adds no fee or markup of its own. Network, provider and bridge costs still apply. Some are built into the quoted amount rather than listed separately, so check what you pay and what you receive before you confirm.
Cross-chain in one command
Moving between chains with Tangem means a bridge interface on top of the device. ChainATM routes cross-chain swaps automatically via LI.FI across 9 networks.
