Tychi vs. Tangem: The Battle of the NFC Crypto Cards

NFC-based cold wallets are having a moment. The form factor — a card that fits in a regular wallet, no USB cable, no screen, tap-to-sign on a phone — is winning ground from screen-equipped hardware wallets for the user who values ergonomics over absolute control. Two products dominate the conversation: Tangem, the Swiss-engineered card that has been shipping for years, and the Tychi Cold Wallet, our entry, shipping soon.

This is the honest version of the comparison. Both products are useful. They make different trade-offs, and the right choice depends on what you are optimizing for.

What they share

Both are NFC cards, roughly the size of a credit card, designed to be tapped against a phone to sign transactions. Both let users avoid USB cables, drivers, and the desk-bound feel of a Ledger or Trezor. Both keep private keys offline by default. Both target users who want hardware security without the hardware-wallet learning curve.

If you have used a Tangem and tried a Tychi card, the basic motion — open app, present card, tap, done — feels familiar.

Where Tangem leads

Tangem has years of shipping behind it. That maturity shows up in concrete places.

Multi-card sets. Tangem ships in 2-card and 3-card packs by default, so users can keep redundant cards in different physical locations. The recovery story is well-thought-out and battle-tested.

Chain coverage. Tangem supports a wide list of chains directly through its app. Coverage is broad and stable.

Audited firmware. Tangem firmware has been independently audited multiple times. The product has institutional trust built up.

Distribution. You can buy Tangem cards through standard retail channels in many countries. Logistics are a solved problem.

If maximum chain coverage and a mature recovery flow are your priorities, Tangem is the right call.

Where Tychi leads

Three places where Tychi takes a different approach.

Native UGF integration. The Tychi Cold Wallet is paired with the Tychi Wallet app, which means cold-signed transactions can use the Universal Gas Framework. You can sign a Solana transaction from the cold card while paying gas in USDC on Base. No other NFC wallet currently does this — most assume the user has native gas on the destination chain.

The 12+3 usability split. Tychi uses a 15-word setup: 12 standard seed words on the card, 3 personal words held by the user. This is not a cryptographic upgrade — see our cold wallet writeup for the honest math. It is a usability split. For users who fail at backing up a 24-word seed correctly (which is most users), it shifts the failure mode toward something more recoverable.

Open hardware path. Tychi works with the official Tychi card or any fresh NTAG215 NFC card. No vendor lock-in. If we go away, your card still works with any NTAG215-compatible setup. Tangem cards only work with Tangem's app.

What's the same when it counts

A few things both products deal with the same way:

• Single-point-of-failure risk. If you lose all your cards and forget your recovery information, both wallets are unrecoverable. Hardware is hardware.
• Phone dependency. Both require a phone running the corresponding app. Neither works standalone.
• No on-card display. Neither has a screen. You verify transactions on the phone, which means you trust the phone's display. (Screen-equipped wallets like Trezor Safe 5 or Ledger Flex are a different category — see the hardware wallet buyer's guide.)

How to choose

Three questions to ask yourself.

Do you need maximum chain coverage today? Pick Tangem. Their support list is the most comprehensive in the NFC category.

Do you operate across both EVM and non-EVM and want one-token gas? Pick Tychi. UGF integration is the differentiator.

Are you nervous about vendor lock-in? Slight edge to Tychi for the NTAG215 compatibility. Tangem cards still work without Tangem-the-company indirectly via the wallet's recovery flow, but the apps are not interchangeable.

What we're not claiming

We are not saying Tychi is "more secure" than Tangem. The cryptographic primitives are similar. The 12+3 split is a UX trade, not a math improvement. We are not saying Tangem is wrong for any user — for many users, the maturity of Tangem's product is exactly the right fit.

What we are saying is that the NFC cold wallet category has room for more than one player, and the trade-offs are real. If your day-to-day involves cross-chain action and you want hardware security on top of it, the Tychi flow exists for that case.
