Samsung Electronics has submitted a United States patent application for a crypto wallet that leverages smart contracts to manage digital asset transactions. The patent, published on July 23 under publication number US 2026/0212355, outlines a new system that may allow devices to initiate transactions without the need to store or directly use private keys.
Smart contract solution for private key management
The technology described in the patent would move a portion of wallet functionality from a user’s device onto a blockchain-based smart contract. By doing so, Samsung targets a long-standing challenge in crypto management: the risk associated with users handling their own wallet credentials and private keys.
Traditional crypto wallets require users to sign each blockchain transaction using a private key. If the private key is lost, access to funds is permanently blocked; if it is exposed, wallets become vulnerable to unauthorized access and loss of assets.
According to the filing, Samsung’s proposal involves assigning device-specific addresses and authentication, with supporting devices registering these credentials before a smart contract is deployed. When a user wishes to make a transaction, the relevant device sends the transaction information, its assigned address, and its authentication details to the smart contract. Details such as the recipient’s blockchain address, asset type, and transaction amount are included in the transmission.
The smart contract compares the incoming information with previously registered credentials. If the data matches, the smart contract initiates the requested transaction.
Although private keys are not entirely eliminated under the design, the patent specifies that transactions ultimately rely on the smart contract’s own blockchain address and private key, rather than those stored on user devices.
Mini dictionary: Smart contract — A smart contract is a self-executing computer program on a blockchain that automatically performs actions when specific conditions are met, removing the need for intermediaries in digital transactions.
Multi-device wallet management on the horizon
The patent also describes how the system could enable a single digital asset wallet to be managed across multiple devices. Under this setup, one device may initiate transactions, while others handle wallet registration, address changes, or recovery tasks. New addresses and authentication credentials can be added to the smart contract as needed.
The company identifies smartphones, computers, wearable technology, and even home appliances as devices that could participate in this multi-device wallet system. This strategy could connect digital asset management throughout various Samsung products, offering a unified crypto experience for consumers.
Samsung’s filing comes as the company looks to expand its presence in the digital asset sector. In July, Samsung revealed plans to introduce stablecoin support in Samsung Wallet, but it has yet to confirm which tokens or networks will be included or when this will be launched.
The patent does not clarify whether this smart contract architecture will be used for Samsung’s announced stablecoin integration or if it will be incorporated into Samsung Wallet. No timeline or commercial release details have been provided.
Despite the innovation, Samsung’s application currently represents a potential architecture rather than a finalized consumer product. The company has not disclosed specific plans or schedules for commercialization.
