Our take
Atomic Wallet
Atomic Wallet serves as a versatile software client for managing multi-chain cryptocurrency holdings across desktop and mobile devices. By maintaining a non-custodial model, the application helps support that 12-word seed phrases and private keys remain encrypted locally on client hardware rather than on company servers. This structure eliminates account creation requirements and provides direct access to hundreds of decentralized networks.
However, the platform relies on external liquidity providers for in-wallet swaps and fiat purchases, which can introduce spread markups and third-party fee structures. Additionally, because the client is partially closed-source, users must place trust in the software release pipeline. For everyday multi-asset management and non-custodial staking, Atomic Wallet offers a practical interface, provided users maintain strict device hygiene and rigorous backup routines.
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.
