1. A method, comprising:
creating, by a node of a first distributed ledger technology (DLT) network, 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, by the digital wallet of the first DLT network, 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, by the node of the first DLT network 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.
