Abstract:

Methods, systems, and apparatus for risk mitigation for a cryptoasset custodial system include transmitting an endorsement request for a cryptoasset transaction to a user device configured to cause the user device to prompt a user to endorse the cryptoasset transaction. Multiple data points are collected from mobile devices associated with the user. The data points indicate an identity of the user. A cryptographic endorsement of the cryptoasset transaction is received from the user device. A graphical visualization including a risk metric is generated based on the data points. The risk metric indicates a risk of accepting the cryptographic endorsement from the user device. Generating the graphical visualization includes determining whether the plurality of data points matches expected values.
