Our take

Tangem

Tangem offers a distinctive approach to cold storage by packaging a secure element into a durable bank card form factor. Founded in Switzerland in 2017, the company designed its hardware without internal batteries, charging ports, or connecting cables. Users interact with their digital assets by tapping the smart card against an NFC-enabled mobile phone running the companion application. The architecture stands out for offering a seedless recovery model alongside traditional BIP39 mnemonic passphrases. When configured without a seed phrase, the private key is generated directly inside the secure element and cloned securely across companion backup cards. This setup removes the risk of exposing paper backups to theft, though transaction validation relies on the paired smartphone screen. Tangem delivers practical and highly portable self custody for everyday cryptocurrency holders.

Unchained Capital

Unchained Capital delivers an institutional grade architecture tailored around Bitcoin native sovereignty. By employing an on chain 2 of 3 collaborative custody vault structure, the platform removes single points of failure without leaving users isolated. The customer holds two hardware keys directly, giving them mathematical sovereignty over their funds at all times, while Unchained holds a single key to assist with co signing transactions, technical recovery, and estate planning workflows. This arrangement effectively bridges sovereign cold storage with managed enterprise infrastructure.

While Unchained eliminates third party commingling risks common to centralized exchanges, it requires disciplined operational hygiene. Setting up hardware devices and coordinating quorum signatures demands deliberate effort, and fees on the entry level trading tier are noticeably higher than spot market exchanges. For long term Bitcoin holders, family offices, and self directed retirement accounts, Unchained provides a balanced, resilient custody model.

Product design and multi-chain asset coverage

Tangem

Tangem operates as a specialized self-custody hardware manufacturer whose primary consumer offering is the Tangem Wallet pack. Each pack consists of either two or three identical smart cards embedded with an industrial-grade secure chip. The hardware contains no moving parts, screens, or batteries, relying entirely on the near-field communication field generated by the paired smartphone to power cryptographic operations during transaction signing.

On the asset side, Tangem supports thousands of individual cryptocurrencies across dozens of layer-1 and layer-2 blockchain networks. Supported networks include Bitcoin, Ethereum, Solana, BNB Smart Chain, Ripple, Cardano, Avalanche, Polygon, and Arbitrum, alongside extensive catalogs of ERC20 and other token standards. Token management takes place inside the Tangem mobile app for iOS and Android, which pulls real-time balance data through public blockchain endpoints and network nodes.

Users can interact with decentralized applications through standard WalletConnect integrations embedded in the software interface. This workflow enables connection to decentralized trading venues, lending protocols, and non-fungible token marketplaces without exporting private keys from the secure element. Token listings update frequently through app releases, allowing holders to track both major coins and niche assets without requiring manual firmware flashes on the cards themselves.

Unchained Capital

Unchained operates strictly as a Bitcoin native financial platform, purposefully avoiding altcoin support to focus entirely on the script capabilities, security model, and liquidity of the Bitcoin network. The foundational product is the collaborative custody vault, which creates an on chain multisignature address requiring two separate private keys to authorize any transaction. Account tiers accommodate solo individuals, collaborative families, and complex corporate treasury structures requiring multiple legal signatories.

Beyond standard cold storage vaults, Unchained offers an integrated suite of Bitcoin native financial products. Users can execute spot Bitcoin trades directly into or out of their multisig vaults through Unchained Trading, eliminating the need to move funds through intermediate centralized exchange wallets. The platform also provides Bitcoin backed fiat lending, allowing borrowers to access dollar liquidity against their cold storage Bitcoin without selling or triggering immediate capital gains events. Additionally, Unchained offers self directed Bitcoin IRAs with checkbook control and inheritance planning features that allow designated beneficiaries to navigate probate procedures smoothly without exposing vault keys to third parties during life.

Hardware costs, network fees, and transaction pricing

Tangem

Purchasing a Tangem hardware setup involves a one-time physical product fee rather than recurring software subscriptions. Retail pricing typically ranges between approximately 55 and 70 dollars for a two-card pack, or between 70 and 90 dollars for a three-card set, depending on active promotions, regional shipping duties, and local sales taxes. Tangem also produces specialty branded sets and hardware rings that use the same internal chip architecture at adjusted hardware price points.

Standard blockchain transactions executed through the wallet do not incur platform surcharges from Tangem. Users pay only the mandatory network gas fees required by the underlying blockchain miners or validators. When transferring Bitcoin or native tokens, the companion app allows senders to select custom priority fee tiers to match current network congestion levels without artificial markup.

Optional financial services integrated into the mobile app interface operate through third-party financial intermediaries. When buying crypto with fiat currency or executing cross-chain swaps, services such as MoonPay, Mercuryo, Changelly, and 1inch set their own exchange spreads and processing fees. These service fees vary based on payment channel, geographical jurisdiction, and market volatility, and are presented within the application prior to transaction confirmation.

Unchained Capital

Unchained operates on a tiered pricing model that combines free self directed tools with paid membership tiers offering lower transaction costs and concierge onboarding. On the free standard tier, clients can configure collaborative vaults using their own hardware devices at zero recurring platform cost. However, spot trading fees on this introductory tier sit around 1.99 percent per trade. Paid subscription tiers, such as Unchained Signature, introduce annual retainer fees starting from roughly 1,500 to 4,000 dollars depending on business complexity, while bringing spot trading fees down to 0.75 percent or lower for higher volume executions.

Depositing funds into multisig vaults does not incur platform surcharges beyond standard Bitcoin miner transaction fees. When initiating withdrawals or co signed transfers, users pay regular on chain network transaction fees determined by prevailing mempool congestion. If a client requires Unchained to co sign an outgoing transaction, Unchained applies no platform surcharge for standard signature requests on personal accounts. For Bitcoin backed loans, interest rates fluctuate based on broader macroeconomic rates and institutional lending conditions, accompanied by an origination fee typically ranging from 1 to 2 percent of the principal loan balance.

Custody architecture, chip certification, and access controls

Tangem

Tangem is strictly a non-custodial hardware provider, meaning the company never holds, manages, or possesses access to user funds, private keys, or wallet balances. At the core of every card is a certified EAL6+ microchip produced in collaboration with major semiconductor fabricators. The chip firmware is fixed at manufacturing, which prevents unauthorized remote firmware alterations or malicious over-the-air updates from compromising key isolation.

Security relies heavily on the card pairing and backup workflow. During initial configuration, the primary card generates a cryptographic key pair via an integrated true hardware random number generator. If the seedless mode is selected, the private key is transferred over an encrypted NFC communication channel directly to the secondary and tertiary backup cards, after which the key is mathematically impossible to extract from the chips. Alternatively, users who prefer traditional disaster recovery workflows can choose to generate or import a standard 12 or 24 word BIP39 seed phrase.

Day-to-day spending controls include a user-defined access code configured during setup. This access code prevents unauthorized parties from tapping a stolen card to sign transactions. If an access code is forgotten, the wallet enforces an escalating biometric or multi-card reset process requiring multiple backup cards to restore access, mitigating single-point-of-failure risks.

Unchained Capital

The security architecture of Unchained rests upon the mathematical is intended to support of Bitcoin native Script multisignature protocols. In a standard setup, three separate cryptographic keys are generated across independent hardware devices. The client holds two keys, typically stored on distinct hardware authenticators from vendors like Trezor, Ledger, Coldcard, or Foundation Passport. Unchained holds the third key inside an enterprise grade security perimeter. Because spending requires two valid signatures, Unchained cannot move client funds independently, protectively isolating assets from platform insolvency, internal rogue actors, or unauthorized unilateral seizures.

Users retain full independence to broadcast transactions without Unchained intervention by using external open source coordinator tools, such as Caravan. If Unchained were ever to experience downtime or service disruptions, clients holding their two personal hardware keys can independently assemble, sign, and broadcast transactions directly to the Bitcoin network. Platform authentication incorporates robust multi factor verification, device registration helps protect, and optional video verification protocols for high value collaborative signing requests, ensuring operational security matches on chain cryptographic protections.

Global distribution, platform compatibility, and support channels

Tangem

Tangem ships hardware units internationally from fulfillment centers located across Europe, North America, and Asia. Device availability is subject to local trade restrictions, consumer import regulations, and standard international courier routes. Because the cards function as consumer electronics for key management rather than a custodial financial institution, users worldwide can hold and sign assets without opening regulated banking accounts through Tangem.

Hardware compatibility requires a modern smartphone equipped with an active NFC antenna and a supported operating system, specifically iOS or Android. Desktop users cannot sign transactions directly via USB, as the physical cards do not possess contact connectors. Software distribution occurs through standard mobile channels including the Apple App Store, Google Play Store, and downloadable open-source Android package kits hosted on GitHub.

Customer support is available through direct email ticketing, integrated in-app help desks, and community discussion groups across Telegram, Discord, and Reddit. Tangem maintains extensive online knowledge bases covering setup guides, replacement procedures, and token support lists. Technical support cannot reset access codes, restore missing private keys, or reverse on-chain transactions, maintaining strict boundaries aligned with non-custodial software principles.

Unchained Capital

Unchained Capital is headquartered in Austin, Texas, and operates in full compliance with United States financial regulations, maintaining applicable state lending licenses and money transmission compliance standards. Vault custody services and the open source Caravan software are accessible worldwide to users possessing compatible hardware devices. However, integrated fiat trading, Bitcoin backed lending, and specialized retirement IRA products are subject to geographic eligibility rules, primarily serving United States residents and incorporated commercial entities across supported states.

Support capabilities vary meaningfully based on the selected tier. Free tier users receive standard email and ticketed customer support alongside comprehensive setup documentation, open source guides, and knowledge base resources. Clients enrolled in paid tiers gain access to dedicated client service managers, tailored video onboarding sessions, hardware device configuration assistance, and coordinated inheritance consultations. This white glove onboarding helps non technical family members and enterprise treasury managers navigate hardware device setup and multisig quorum coordination without operational confusion.

Custom token management and dApp connectivity

Tangem

Tangem handles broad multi-chain asset requirements by combining native blockchain support with custom token configuration. Users can add unlisted tokens on supported smart contract networks by manually pasting verified contract addresses directly into the mobile application. This setup allows holders to track specialized assets across multiple layer-1 and layer-2 networks within a unified portfolio interface. The integrated WalletConnect protocol enables direct interaction with decentralized liquidity pools, lending protocols, and NFT marketplaces on mobile web browsers while keeping private keys isolated inside the card. Broad network coverage helps support straightforward management across major blockchains such as Bitcoin, Ethereum, and Solana. Overall, the companion app bridges cold storage security with versatile Web3 decentralized application connectivity on supported mobile devices.

Unchained Capital

Unchained supports a broad range of industry standard hardware wallets, allowing users to combine different device manufacturers to eliminate single vendor supply chain vulnerabilities. Compatible hardware includes Ledger, Trezor, Coldcard, and Foundation devices. Vaults are constructed using native Segregated Witness (SegWit) P2WSH addresses, optimizing on chain byte efficiency and minimizing miner transaction fees during multi key signing routines.

Because the platform strictly integrates with native Bitcoin protocols, it does not support Ethereum, stablecoins, or wrapped assets. Account balances exist exclusively as unspent transaction outputs (UTXOs) on the Bitcoin blockchain, verifiable in real time via public block explorers or a user's own sovereign Bitcoin node.

Physical security factors and operational considerations

Tangem

Tangem cards feature an IP68 environmental rating, offering resistance against continuous water immersion, fine dust intrusion, and extreme operating temperatures. Unlike traditional hardware wallets with delicate screens, there are no internal solder joints susceptible to drops or rechargeable batteries prone to chemical degradation over time. The monolithic plastic card design protects the internal EAL6+ certified microchip against common physical hazards encountered during routine transport. Users must store backup cards in geographically separated, secure locations to prevent simultaneous loss from regional emergencies or household theft. Because the physical card lacks an onboard visual display screen, users must review all transaction details and receiving addresses carefully on their mobile screen before tapping the card. Maintaining access code privacy helps support protection against unauthorized physical tap attempts on lost devices.

Unchained Capital

While collaborative custody removes unilateral custodian risk, it introduces operational responsibilities for the user. If an account holder loses both of their personal hardware keys and backup seed phrases, Unchained cannot recover the funds because the single key held by the company cannot meet the two key spending quorum. Client asset security ultimately depends on disciplined key management, secure seed phrase storage, and physical device isolation.

In the Bitcoin backed lending program, market volatility introduces collateral liquidation risks. If the price of Bitcoin falls below stipulated loan to value thresholds, borrowers must post additional collateral or repay principal to avoid partial liquidation of locked collateral. Unlike traditional custodial brokerages, assets are held in dedicated multisig addresses rather than pooled omnibus accounts, keeping property titles legally distinct under applicable commercial property laws.

Who it suits

Tangem

Tangem is best suited for cryptocurrency investors who want cold storage security without the complexity of traditional hardware wallets. Users who dislike managing handwritten seed phrase backups will appreciate the card-to-card cryptographic cloning mechanism. It is also an attractive option for frequent mobile users who prioritize quick physical NFC tap verification over desktop-based USB hardware setups.

It may be less ideal for advanced desktop traders who require direct USB browser extensions, physical screen verification for complex smart contract calls, or complex multi-signature governance frameworks. Those users may prefer hardware options with onboard displays and native desktop applications.

Unchained Capital

Unchained Capital is best suited for long term Bitcoin accumulators, family offices, self employed retirement savers, and enterprise treasuries seeking institutional grade security without relinquishing sovereign control. It delivers exceptional value to users who want cold storage multisig protection alongside accessible assistance for trade execution, dollar lending, and multi generational estate planning.

Prospective users who want automated algorithmic trading, high frequency multi asset exchange execution, or support for alternative cryptocurrencies will find the platform unsuitable for their daily transactional needs.
