Samsung Application Describes Smart Contract Wallet for Multiple Devices

Samsung Electronics has outlined a wallet design in a U.S. patent application that lets registered devices request blockchain transactions through a smart contract, allowing multiple devices to participate without each holding the contract’s private key.

The application, published July 23, describes one device registering another with an address and authentication information. When the second device requests a transaction, the smart contract checks those details and can process the request if they match.

The contract would use its own blockchain address and private key. A requesting device therefore would not need to submit a blockchain signature generated with that key. The proposed arrangement keeps a private key at the smart-contract level.

The application also describes multiple devices taking different roles. Devices could request transactions or help update and recover addresses. The filing does not establish that Samsung has built or tested the system, or that it will be added to Samsung Wallet.

Samsung has offered Blockchain Keystore on some Galaxy devices. The feature stores a user’s private key in a secure area of the phone and can sign blockchain transactions. The application describes a different proposed setup, with a smart contract performing wallet functions on a blockchain.
