Samsung Electronics Files US Patent Application for Smart-Contract Crypto Wallet

Samsung Electronics has reportedly filed a U.S. patent application for digital wallet technology that would allow users to request cryptocurrency transactions through smart contracts without directly managing their private keys.

Digital Asset reported on October 6 that Samsung's patent application, titled "First Electronic Device Configured to Generate Smart Contract Set to Perform Wallet Function, Operating Method Thereof, and Second Electronic Device for Performing Digital Asset Transaction Using Smart Contract," was published in the United States on July 23. The publication number is US 2026/0212355.

The technology is designed so that a smart contract performs part of a digital-asset wallet's functions instead of having a user's device directly manage the private key.

In a typical crypto wallet, a user signs transaction data with a private key and then transmits it to a blockchain network. If the private key is lost, access to the wallet can become difficult. If it is exposed, the assets could be stolen.

To address that, Samsung proposed linking addresses and authentication information assigned to each electronic device to a smart contract. Under the structure, one device receives another device's request to register a transaction address and authentication information, generates a new transaction address and transmits the information to the blockchain. That creates a smart contract that performs wallet functions.

When a user later requests a transaction, the electronic device sends the transaction data, transaction address and authentication information to the smart contract. The smart contract compares the information with data stored in advance and processes the transaction if the details match.

That means a user's device can request cryptocurrency transactions without directly storing a private key or signing transaction data itself. The private key does not disappear from the system, however. The final transaction may still be executed based on the smart contract's blockchain address and private key.

The patent also includes a structure that allows multiple devices to manage a single wallet. When a new device is added to the wallet or an existing transaction address is changed or restored, another device can support the process and register the new address and authentication information with the smart contract.

That would make it possible to manage a single cryptocurrency wallet across multiple electronic devices, including smartphones, computers, wearables and home appliances.

Still, the patent filing does not mean the technology is being developed into a commercial product. The patent document does not say whether it would be applied to Samsung Wallet, nor does it include a specific launch plan or commercialization timeline.
