Samsung Electronics has filed a U.S. patent application for a smart-contract-based crypto wallet designed to simplify digital asset transactions. Under the proposed system, devices could initiate transactions without directly storing or using private keys, moving part of a wallet's core functionality onto a blockchain network. The filing describes an architecture in which a smart contract handles portions of the wallet's functions, a design that could also allow several devices to manage a single wallet.

Smart Contract Wallet Targets Private Key Management

According to a Digital Asset report published on Oct. 6, the patent appeared in the United States on July 23 under publication number US 2026/0212355. Samsung Electronics is listed as the applicant, and the filing itself was submitted on March 13, 2026. Published U.S. patent applications disclose an invention's details, but publication by itself does not mean the patent has been granted or that a product is in development.

The technology transfers part of the wallet's functionality from an individual device to a smart contract operating on a blockchain network. That shift could reduce how often users need to handle sensitive wallet credentials directly.

Traditional crypto wallets generally require users to sign transactions with private keys before submitting them to a blockchain. Losing a private key can lock users out of their funds entirely, while exposure of the key creates a risk of unauthorized transactions. Smart-contract wallets are an established category in the industry, using on-chain code to handle credential checks and recovery options that a standalone private key cannot provide on its own.

Samsung's patent addresses these challenges through device-specific addresses and authentication information. A supporting device can register those details with the blockchain before a smart contract is created. When a user initiates a transaction, the device transmits the transaction details, its assigned address, and its authentication information to the smart contract. That information can include the recipient's blockchain address, the asset type, and the transaction amount.

The smart contract compares the submitted data against previously registered information. If the details match, the contract processes the requested transaction.

The proposed system does not eliminate private keys entirely. According to the patent, the final transaction can still rely on the smart contract's blockchain address and the private key associated with it.

Multi-Device Wallet Management

The filing also describes managing a single digital asset wallet across multiple electronic devices, potentially extending wallet access beyond one smartphone or dedicated hardware device. Under the proposed structure, one device can request a transaction while another supports wallet registration, address changes, or recovery, with newly generated addresses and authentication information registered to the smart contract.

Samsung identifies smartphones, computers, wearable devices, and home appliances as potential devices for the system, an approach that could connect digital asset management across several parts of the company's hardware ecosystem.

Proposed Architecture, Not a Confirmed Product

The development arrives as Samsung broadens digital asset functionality in its consumer products. In July, the company announced plans to add stablecoin support to Samsung Wallet, though it did not identify supported tokens, blockchain networks, or a launch date.

The new patent does not specify whether the smart-contract architecture would support those planned stablecoin features, nor does it confirm integration with Samsung Wallet or any other commercial service. As a result, the filing represents a proposed wallet architecture rather than a confirmed product release. Samsung has not provided a commercialization schedule or confirmed plans to deploy the technology in its existing services. Whether the design advances from filing to product would become clear only through Samsung's own announcements or the patent's progress through the U.S. patent system.
