the affiliated contract address refers to a contract address of a contract to which the digital asset belongs, and since a contract may contain asset accounts of a plurality of digital assets, the affiliated contract address in the asset parameters cannot uniquely identify the asset account;
the asset identification refers to identification information of asset accounts, the asset identifications in the same contract are different, but the asset identifications in different contracts can be the same or different, and because the asset accounts can have a cross-contract condition, the asset identifications in a full chain or different contracts can not uniquely identify the asset accounts, but the asset accounts can be used as unique identification information for identifying the asset accounts corresponding to the digital assets, or the asset identifications and the affiliated contract addresses can also be used as unique identification information for identifying the asset accounts corresponding to the digital assets;
the asset state is to record state information of an asset account corresponding to the digital asset, and the asset state can be set according to user requirements, for example, the asset state is set to be active;
the owner address is an address of an owner of the asset account corresponding to the recorded digital asset, for example, the owner of the asset account recorded in the owner address is a;
the second-creation identification is identification information for recording updating and creation of an asset account corresponding to the digital asset, and the second-creation identification can also comprise an address from which asset account comes;
the preset custom information is created according to the requirements of the user on the asset account corresponding to the digital asset.
In this embodiment, a digital asset management device responds to an asset account creation request, the digital asset management device obtains an asset parameter associated with the asset account creation request, and the digital asset management device creates an asset account corresponding to a digital asset according to the asset parameter, specifically, the method includes:
and 202, calling a preset asset casting contract to cast the digital assets according to the asset parameters, and creating and storing asset accounts corresponding to the digital assets.
