Abstract: Certain aspects of the present disclosure provide techniques for generating digital tokens associated with an asset on a blockchain. An example method generally includes receiving a request to create a digital token corresponding to an asset. A first private key is received. This first private key may be associated with a wallet in which the digital token is to be stored. A second private key is received from a physical device associated with an owner of the asset. An address of the asset is encrypted with a public key associated with the second private key. Metadata associated with the digital token is encrypted with a public key associated with the first private key. The digital token is minted on a blockchain based on the encrypted address of the asset and the encrypted metadata.
