Abstract
In a general aspect, a distributed ledger transaction is generated on a cold hardware wallet. Generating the distributed ledger transaction includes receiving, at the cold hardware wallet, ledger information from a network-connected device via a private module-to-device communication link. The ledger information may include account information for the distributed ledger transaction, and a timestamp identifying when the account information was received by the network-connected device from a public network. The cold hardware wallet may generate a message based on the account information, identify a private key stored in the cold hardware wallet, generate a digital signature based on the message and the private key, and generate the distributed ledger transaction based on the message and the digital signature. The cold hardware wallet may send the distributed ledger transaction to the network-connected device via the private module-to-device communication link for forwarding to the public network for settlement.
