- Samsung’s patent lets smart contracts handle parts of crypto wallet functions.
- The system could allow multiple devices to manage a single digital asset wallet.
- The filing does not confirm Samsung Wallet integration or a commercial launch.
Samsung Electronics has filed a U.S. patent application for a smart-contract-based crypto wallet designed to simplify digital asset transactions. The proposed system could allow devices to initiate transactions without directly storing or using private keys.
Samsung’s Smart Contract Wallet Targets Private Key Management
According to a Digital Asset report on Oct. 6, the patent was published in the United States on July 23 under publication number US 2026/0212355. Samsung Electronics is listed as the applicant, while the filing was submitted on March 13, 2026.
The technology shifts part of the wallet’s functionality from an individual device to a smart contract on a blockchain network. This approach could reduce the need for users to manage 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 prevent access to funds, while exposing it can create a risk of unauthorized transactions.
Samsung’s patent addresses these challenges through device-specific addresses and authentication information. A supporting device can register these details before a smart contract is created on the blockchain.
When a user initiates a transaction, the device sends transaction details, its assigned address and authentication information to the smart contract. The information can include the recipient’s blockchain address, asset type and transaction amount.
The smart contract then compares the submitted information against previously registered data. If the details match, the contract processes the requested transaction.
However, the proposed system does not eliminate private keys entirely. The patent indicates that the final transaction can still rely on the smart contract’s blockchain address and associated private key.
Samsung Patent Enables Multi-Device Wallet Management
The patent also describes managing one digital asset wallet across multiple electronic devices. This could extend wallet access beyond a single smartphone or dedicated hardware device.
Under the proposed structure, one device can request a transaction while another supports wallet registration, address changes or recovery. Newly generated addresses and authentication information can then be registered with the smart contract.
Samsung identifies smartphones, computers, wearable devices and home appliances as potential devices for the system. The approach could therefore connect digital asset management across several parts of Samsung’s hardware ecosystem.
The development comes as Samsung expands digital asset functionality within its consumer products. The company announced plans in July to add stablecoin support to Samsung Wallet, although it did not identify supported tokens, blockchain networks or a launch date.
The patent does not specify whether the smart-contract architecture will support those planned stablecoin features. It also does not confirm integration with Samsung Wallet or another 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.
