System and method for generating blockchain token support from a set of declarations
Described herein are systems and methods for generating blockchain token support from a set of declarations. In accordance with an embodiment, an application builder (App Builder, Application Builder) component of a blockchain, blockchain cloud system, or other blockchain solution (e.g., Oracle Blockchain Platform) can provide a mechanism to define blockchain assets using a declaration or specification file, and then generate a blockchain smart contract that supports those assets. In accordance with an embodiment, the systems and methods described herein provide a mechanism for defining Tokens (e.g., Fungible or Non Fungible Tokens) adhering to a framework, such as the Token Taxonomy Framework, and generating the appropriate methods as defined by the token properties.

writing the chaincode to a memory associated with the application builder;
transferring the automatically generated code to the chaincode component to be run on the ledger component; and
testing and debugging the automatically generated code prior to the automatically generated code being transferred to the chaincode component.
