  • Publication number: 20240330904
    Abstract: Securing digital assets in a vault that interfaces with multiple different third-party wallets to store keys/mnemonics. The vault interface accepts input from multiple different party wallets to combine multiple encryptions and secure storage techniques. Numerous cryptographic mechanisms are employed to securely pull a mnemonic phrase from a third-party wallet and into an institution's vault. A customer's mnemonic phrase is securely transported from a personal wallet into a secured institution's encrypted vault using the power of HSM to encrypt and decrypt a customer's mnemonic phrase securely.

  • Patent number: 11416848
    Abstract: A system and method for preventing the double-spending of digital currency that transfers between multiple distributed ledger technology (DLT) networks. The system and method includes receiving an authorization to monitor transaction requests associated with a first DLT network. 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 first digital currency is created on the first DLT network based on a unit of fiat currency. The system and method include transferring, responsive to detecting the transaction request, the first digital currency from the first DLT network to the second DLT network.

  • Publication number: 20240289779
    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.

  • Publication number: 20240330907
    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.

  • 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.
