Samsung Patents Smart-Contract Crypto Wallet with Multi-Device Support

Samsung Electronics has filed a U.S. patent for a crypto wallet system that leverages smart contracts to manage digital asset transactions. The proposed technology aims to simplify wallet functions by shifting some operations from individual devices to a smart contract on a blockchain network. This approach could reduce the need for users to directly handle sensitive private keys, which are crucial for accessing and securing crypto funds.

The patent, published on July 23, 2026, under number US 2026/0212355, outlines a system where devices can initiate transactions without storing private keys. Instead, a smart contract verifies transaction details against registered device-specific addresses and authentication information. If the details match, the smart contract processes the transaction, though the final step still relies on the contract’s private key.

One notable feature of the patent is the ability to manage a single digital asset wallet across multiple devices. This could allow users to access their wallet from smartphones, computers, wearables, or even home appliances, integrating digital asset management into Samsung’s broader hardware ecosystem. The filing does not confirm, however, whether this technology will be integrated into Samsung Wallet or any other commercial service.

While Samsung has previously announced plans to add stablecoin support to Samsung Wallet, the patent does not specify if the smart-contract architecture will support those features. As of now, the filing represents a proposed wallet design rather than a confirmed product release, with no details on a commercialization timeline.
