  • Cryptographic signature delegation
    Patent number: 11956374
    Abstract: A computing system that is configured for a federated wallet with cryptographically secure signature delegation. The system may be configured to receive a session public key corresponding to a decentralized application and a user. The system may be further configured to receive an unsigned transaction of a blockchain, the unsigned transaction corresponding to the user. The system may be further configured to provide a symmetric encryption key to the user's device for encrypting the user's private signing key. The system may be further configured to determine, using the session public key, that the unsigned transaction is valid. Based on the validity of the unsigned transaction, the system may send the unsigned transaction to the user's device. The system may send the symmetric encryption key to the user's device to decrypt the private signing key. The system may be further configured to receive a signed transaction for submission to the blockchain.
