  • Patent number: 12586061
    Abstract: A system and method for preventing the double-spending of digital currency that transfers between multiple DLT networks. The system and method includes creating a first digital currency of a first type on the first DLT network stored in a digital wallet, the first digital currency associated with a second digital currency of a second type on a second DLT network, configuring a monitoring agent on the node, the monitoring agent configured to intercept at least one of a function call, a message, or an event on the digital wallet, and locking, responsive to intercepting the at least one of the function call, the message, or the event, the first digital currency onto the first DLT network to prevent a transfer of the first digital currency from the digital wallet on the first DLT network to another DLT network responsive to a subsequent transaction request.

  • Publication number: 20250371526
    Abstract: A method for preventing the double-spending of digital currency that transfers between multiple distributed ledger technology (DLT) networks. The method includes detecting a request to transfer a first digital currency from the a DLT network of a first type to a second DLT network of a second type. The method further includes, in response to an indication from an exchange node that the first digital currency is to be destroyed, destroying the first digital currency from the first DLT network. The method further include creating a second digital currency on the second DLT network. Creating the second digital currency on the second DLT network further includes attaching a serial number to the second digital currency.

  • Patent number: 12400219
    Abstract: A method for preventing the double-spending of digital currency that transfers between multiple distributed ledger technology (DLT) networks. The method includes receiving a message including a smart contract and executing the smart contract. The method further includes detecting a transaction request to transfer the first digital currency from the first DLT network to the second DLT network. The method further includes destroying the digital currency and creating, based on the unit of fiat currency, a second digital currency of a second type on the second DLT network. The method further includes transferring, responsive to detecting the transaction request, the first digital currency from the first DLT network to the second DLT network.

  • Patent number: 11526875
    Abstract: A system and method for preventing the double-spending of digital currency that transfers between multiple DLT networks. The system and method includes creating, based on a unit of fiat currency, a first digital currency of a first type on a first DLT network and a second digital currency of a second type on a second DLT network. Each of the first digital currency and the second digital currency simultaneously represent a value associated with the unit of fiat currency. The system and method includes detecting a transaction request to transfer the first digital currency from the first DLT network to the second DLT network. The system and method include locking, responsive to detecting the transaction request, the first digital currency onto the first DLT network to prevent a transfer of the first digital currency from the first DLT network to another DLT network responsive to a subsequent transaction request.
