erc7730.model.input.descriptor module

Package implementing an object model for ERC-7730 input descriptors.

This model represents descriptors before resolution phase:

  • URLs have been not been fetched yet

  • Contract addresses have not been normalized to lowercase

  • References have not been inlined

  • Constants have not been inlined

  • Field definitions have not been inlined

  • Nested fields have been flattened where possible

  • Selectors have been converted to 4 bytes form

Bases: Model

An ERC7730 Clear Signing descriptor.

This model is directly serializable back the original JSON document.

Specification: https://github.com/LedgerHQ/clear-signing-erc7730-registry/tree/master/specs

JSON schema: https://github.com/LedgerHQ/clear-signing-erc7730-registry/blob/master/specs/erc7730-v1.schema.json

Fields:
field context: InputContractContext | InputEIP712Context [Required]

The binding context is a set of constraints that are used to bind the ERC7730 file to a specificstructured data being displayed. Currently, supported contexts include contract-specificconstraints or EIP712 message specific constraints.

field display: InputDisplay [Required]

The display section contains all the information needed to format the data in a human readableway. It contains the constants and formatters used to display the data contained in the bound structure.

field metadata: InputMetadata [Required]

The metadata section contains information about constant values relevant in the scope of thecurrent contract / message (as matched by the context section)

field schema_: str | None = None (alias '$schema')

The schema that the document should conform to. This should be the URL of a version of the clear signing JSON schemas available under https://github.com/LedgerHQ/clear-signing-erc7730-registry/tree/master/specs
