  • Patent number: 11978038
    Abstract: Methods and systems for digital hot wallet protection are provided. A payment channel is established via a Layer-2 network of a cryptocurrency blockchain for transferring a cryptocurrency balance from a first digital wallet of a service provider to a second digital wallet of a trusted entity over a plurality of commitment transactions. A transaction receipt for each commitment transaction is transmitted to the trusted entity via a secure communication channel previously established between the service provider and the trusted entity outside of the Layer-2 network. A transaction log of the service provider is modified so that it no longer represents the current transaction state of the payment channel Responsive to detecting a breach of the first wallet, a transaction is broadcast to a Layer-1 network of the blockchain for transferring the total cryptocurrency balance from the first wallet to the second wallet.

  • Patent number: 11964247
    Abstract: An apparatus includes a blender lid configured to cover an opening in a blender receptacle and a lid arm coupled to the blender lid and coupled rotationally about a first horizontal axis. The lid arm is configured to rotate about the first horizontal axis to selectively position the blender lid to cover and uncover the opening in the blender receptacle. The blender arm may rotate the blender lid about the first horizontal axis to cover the opening in the blender receptacle and apply a downward force on the blender lid to seal the opening of the blender receptacle with the blender lid. The blender arm may include a horizontal rod having a longitudinal axis that corresponds to the first horizontal axis and having a first end attached to the blender lid.
