US Patent 12014361 Systems and methods for improved hot wallet security

Aspects of the disclosure relate to processing cryptocurrency transactions. A computing platform may receive a transaction request. The computing platform may request SEKs from operator devices, and may receive requests to download encrypted SEKs accordingly. The computing platform may send the encrypted SEKs, and may receive corresponding decrypted SEKs from the operator devices in response. The computing platform may decrypt encrypted shares using the SEKs, and may use the decrypted shares to reconstruct a cryptographic signing key. The computing platform may validate the cryptographic signing key, and based on successful validation of the cryptographic signing key, may transfer authorize the requested transaction.
