According to reports from Digital Asset, Samsung Electronics has filed a U.S. patent application for a digital asset wallet system that uses smart contracts to let devices initiate crypto transactions without directly storing or using private keys. The patent was published in the United States on July 23 under publication number US 2026/0212355, with Samsung Electronics listed as the applicant. The patent records show it was filed on March 13, 2026. The patent application is 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."
The proposed system moves part of the wallet function from individual devices to smart contracts on a blockchain network. As reported by Digital Asset, when a user wants to transfer digital assets, the device sends transaction information, its assigned address and authentication information to the smart contract. The smart contract compares the submitted address and authentication details with information already stored in the contract, and if they match, the smart contract can process the transaction. Private keys would not disappear from the system, but the device requesting the transaction would not need to hold or use that key itself. 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. This smart contract approach addresses these security concerns by eliminating direct private key management.
According to the patent filing, Samsung's proposed structure allows multiple electronic devices to work together to create, change or recover addresses used for crypto transactions. The system supports smartphones, computers, wearable devices and home appliances, with one device potentially requesting a transaction while another supports functions such as registering a new device or recovering an address. A newly generated address and its authentication information can then be registered with the smart contract. 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. This creates a system where a single cryptocurrency wallet can be managed across multiple electronic devices.
The filing comes as Samsung continues expanding digital asset services through its mobile ecosystem. As reported by crypto.news, Samsung announced in July plans to add stablecoin support to Samsung Wallet, with the service eventually supporting stablecoins alongside existing payment, rewards and digital asset functions. Samsung has also integrated Coinbase access into Samsung Wallet for approximately 75 million Galaxy users in the United States. The smart contract wallet patent does not confirm whether the technology will be incorporated into Samsung Wallet or its planned stablecoin services, with no product launch or commercialization schedule included in the filing. The patent document does not specify whether it would be applied to Samsung Wallet, nor does it include a specific launch plan or commercialization timeline.
