Why a Seedless Wallet Made Room for Seed Phrases

In late 2023, Tangem, best known for its “seedless,” tap-to-sign hardware cryptocurrency wallets, shipped a new device that seemed to go against its creed: eliminating seed phrases.

A seed phrase, sometimes called a recovery phrase, is a string of 12 or 24 common words that mathematically encodes a wallet’s master private key. With those words, anyone can import the wallet on any BIP-39 compatible app and move the funds; without them, recovery is impossible. 

Unlike a password, a seed phrase isn’t stored by a company or resettable, making it portable and perilous. It is a single secret that the user must keep entirely offline and never photograph or type into untrusted sites.

For a company that spent years arguing this phrase was a single point of failure, the new Tangem Wallet raised an obvious question. Was this a move to gain market share from the seed-focused self-custody mainstream?

Who is Tangem?

Tangem is a Swiss technology company founded in 2017 and currently headquartered in Luzern. Its signature product is a credit-card-sized crypto wallet that leverages the same NFC technology found in bank cards to sign blockchain transactions. The company positions its cards as simple, durable, and seed-phrase-free by default.

Security is Tangem’s calling card. It points to independent firmware audits by Kudelski Security in 2018, Riscure in 2023, and a firmware-attestation scheme built into the Tangem mobile app. The company also underscores its crypto wallet’s minimalist threat surface, durability, and counterfeit checks. 

The seedless doctrine

For years, Tangem campaigned against seed phrases as risky and error-prone, arguing that paper or metal backups become a single, theft-prone secret that ordinary people routinely mishandle. That doctrine underpinned a different recovery model. The Tangem Wallet allows users to add extra cards as hardware backups, so the user’s private key is redundantly stored across identical secure elements with no mnemonic to hide, copy, or accidentally leak.

Beyond Tangem, a quiet, seedless current has been running through hardware wallets for years. It is more a collection of design assumptions than a single ideology, aiming to minimize human involvement in managing 12 or 24 words.

The flip or the flex?

In September 2023, Tangem listed the seed phrase option as a marquee feature of the new Tangem Wallet, a redesign that also refreshed the card’s aesthetic and introduced a new UI in the app. 

By January 2024, the company was releasing how-to video guides on setting up with a seed phrase. A help-center page titled “Version differences” explains that Tangem Wallet 2.0 supports both seed-phrase generation and import, with options for 12, 15, 18, 21, or 24 words, and it optionally supports passphrases imports. 

Among Tangem loyalists, the rollout landed as a pragmatic compromise rather than a betrayal. Many long-time users welcomed the option because it finally let them migrate standard BIP-39 wallets into Tangem without abandoning the seedless default. Even reviewers loyal to the brand framed it as “requested by many crypto users” while stressing that Tangem still doesn’t recommend the seed path.

At the same time, purists who embraced Tangem precisely to avoid 12 or 24 words said they would keep setting up without a phrase, arguing that adding one defeats the product's purpose. 

Tangem’s public rationale is user demand and interoperability. The company framed the move as independence and versatility for customers who insist on using seed phrases. 

The business calculus

Seed phrases remain the mainstream backbone of self-custody. BIP-39 has standardized the mnemonic format, which is implemented across most wallets, so that users can export/import their wallets between brands.

Large software wallets explicitly derive all accounts from a secret recovery phrase, underscoring how central the model is in everyday use. On the hardware side over 10+ million devices have been built around a recovery phrase by default, entrenching a market expectation in which seed phrases are the go-to recovery method, even as some vendors add alternatives.

There’s no on-the-record admission of a sales motive by Tangem. However, the strategy is sound: by letting users import a standard BIP-39 seed, Tangem opened a low-friction path for seed-phrase users to migrate. It’s a classic way to expand the addressable market without abandoning the seedless default. That inference aligns with the product docs and the marketing line that Tangem is now a universal solution.

A different trust model

Tangem’s core bet is that fixed-function, audited firmware and CC EAL6+ secure elements can reduce real-world risk for normal users more than a mnemonic written on metal ever will. 

Form factor and UX. The card’s NFC antenna is passively powered by a mobile phone, eliminating batteries, cables, and desktop clients. This minimalism is the point; fewer interfaces, fewer traps for users. The hardware is rugged, and Tangem cites IP69K-grade protection as well. Beyond its own blog, mainstream crypto outlets have profiled Tangem’s approach, often highlighting the unusual “no-seed, no screen” design and the audit trail. While no wallet is “unhackable,” the company’s external validations and track records seem stronger than those of typical consumer hardware. 

In the end, Tangem’s turn revealed that the real contest here is how to make self-custody survivable for ordinary people without turning a single mistake into a lifetime loss.

The broader industry is converging on the same compromise. The shard-and-custodian model, vendor-assisted multisig, and others are all attempts to blunt the danger of mishandling twelve words while preserving crypto’s promise of control.

None is free of trade-offs. Seed phrases concentrate risk in one secret while seedless paths distribute it across vendors, devices, identities, or extra hardware that must be safeguarded and, in a crisis, actually found. 

What happens next is more about execution than doctrine. Consumers are voting for two things at once: convenience and security, and they will punish whoever makes them choose. Whether self-custody’s future is twelve words etched on steel or a card you tap to a phone, the winners will be the firms that hide complexity, prove their claims, and absorb human error without compromise.
