Type Script

This determines the type of the Cell, typically defining the conditions for Cell transformation, or state transition constraints. It specifies how the data of new Cells is transformed from old ones. type must have a data structure as Script.

In a transaction, when input Cell and output Cell share the same Type Script, the transformation between them must follow the rules defined by that Type Script.

A typical use case of Type Script is in UDT

Short for User-Defined Token, a customised token created with properties defined by the user.

. In token issuance, new tokens will be created as new Cell outputs, so a Type Script is required to validate that these new tokens are created adhere to predefined rules.

note

Type Script is optional.
