  • Patent number: 12499487
    Abstract: Systems and methods are described for preventing money laundering using a master smart contract. A master smart contract may be recorded on a blockchain, in which the master smart contract comprises one or more containers, that each include one or more tokens. The master smart contract is capable of rebalancing tokens in a container, in which each token is moved between containers in the master smart contract according to an automated process.

  • Publication number: 20250117849
    Abstract: The Decentralized Exchange with Price Oracle Apparatuses, Processes and Systems (“DEPO”) transforms decentralized exchange liquidity provision request, decentralized exchange crypto asset swap request, decentralized exchange liquidity redemption request datastructure/inputs via DEPO components into decentralized exchange liquidity provision response, decentralized exchange crypto asset swap response, decentralized exchange liquidity redemption response outputs. A decentralized exchange liquidity provision transaction is obtained via a bidirectional decentralized exchange smart contract deployed on a blockchain. A crypto assets exchange quotient for exchanging a first crypto asset type and a second crypto asset type is determined. A quantity of fungible tokens specific to a crypto assets liquidity tranche datastructure to generate is calculated.

A decentralized exchange liquidity provision transaction is obtained via a unidirectional decentralized exchange smart contract deployed on a blockchain. A crypto assets exchange quotient for exchanging a source crypto asset type and a target crypto asset type is determined. An imbalance rule check for a crypto assets liquidity tranche datastructure is executed. A non-fungible token specific to the crypto assets liquidity tranche datastructure is minted.

  • Patent number: 12008634
    Abstract: An ordering system described herein can include a rapid reorder of items without needing to re-add the individual items into a shopping cart. The rapid reorder may be triggered via a 3D touch or a long press on a mobile device. The ordering system can also provide an architecture that can allow a user to modify an order, such as, e.g., the pickup time or store location, after the order has been submitted.

  • Publication number: 20210312546
    Abstract: The Secret Key-Based Counterparty Matching Engine Apparatuses, Methods and Systems (“SKCME”) transforms client key message, order placement input inputs via SKCME components into order placement output outputs. A matched key is determined and used to generate a set of cross times and a set of cross venues for a security identifier. Orders associated with the security identifier are obtained from counterparties and are assigned a scheduled cross time from the generated set of cross times and a scheduled cross venue from the generated set of cross venues. The orders are sent for execution at the scheduled cross venue at the scheduled cross time.

  • Publication number: 20190108601
    Abstract: Rapid reordering may be performed by a two-step process. A user interface may present a user with a first user interface control, which can be a button or other user interface control that enables a user interface to initiate an express reorder of a previously-ordered item. Once the user has selected the button, the user interface can present default details about the order along with a second user interface control, which can be a swipe bar or another button (or some other control). User selection of the second user interface control can complete the reorder process. Although described with respect to reordering, this two-step process can also be used for ordering items not previously ordered by a user before.
