Crypto Wallet Configuration Retrieval for Secure State Restoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crypto wallets do not provide users with complete information about the state of their resources upon creating a new instance, leading to user concerns about lost resources and an unfriendly user experience.
Innovation Solution
A device configured to retrieve and display wallet configuration data from cloud storage using a seed, generating and decrypting configuration files to securely manage access rights and display user interface configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a new wallet instance is created without retrieving configuration data, then the wallet can be quickly initialized, but the user will not see complete information about their resources leading to concerns about lost resources
Solution Approach 1:
The system performs preliminary actions by automatically retrieving and restoring wallet configuration data from cloud storage before the user even notices the new wallet instance. The configuration file is fetched using the seed-derived path, decrypted, and the wallet state is restored proactively, so when the user opens the new wallet, all their resources are already visible and accounted for.
Solution Approach 2:
The patent introduces cloud storage as an intermediary between the old and new wallet instances. The configuration file serves as a mediator that carries the wallet state information. Instead of directly copying data between wallet instances, the system uses the cloud storage intermediary to store and transfer the configuration, enabling seamless restoration of wallet state.
2Reliability
If wallet configuration data is stored in cloud storage, then complete wallet state can be retrieved, but security risks increase due to external storage access
Solution Approach 1:
The patent segments the wallet data into two parts: the seed (kept locally and securely) and the configuration file (stored in cloud storage). The seed alone cannot restore the wallet state without the configuration file, and the configuration file is useless without the seed for decryption. This segmentation ensures that even if cloud storage is compromised, the actual cryptographic keys remain secure locally.
Solution Approach 2:
Different parts of the system have different security requirements. The patent applies local quality by keeping the seed (highest security requirement) strictly local on the user's device, while storing less sensitive configuration metadata (lower security requirement) in cloud storage. Each component is stored in the most appropriate location based on its security needs.
3Ease of operation
If manual account creation is required for each resource, then security control is maintained, but the process becomes complex and user-unfriendly
Solution Approach 1:
The system performs self-service by automatically retrieving the configuration file from cloud storage using the seed-derived path, decrypting it using the user's password, and restoring all wallet accounts and resources. This eliminates the need for manual account creation steps, as the wallet configuration is self-restored from the stored configuration data.

AI summary
In various embodiments, a device can be configured to securely implement a wallet capable of displaying data based on a configuration file retrieved from a cloud storage using a seed. In an embodiment, the device can include a display; a network interface; memory; and a processor. The processor can be configured to: obtain a seed value; generate a path value based on the seed value; access a cloud storage location based on the path value; and receive a configuration file from the cloud storage location. The configuration file includes a configuration value. The processor further configured to display a user interface configuration based on the configuration value.
