Metadata

Metadata can be used to inform optional properties that define the specific D-ASA.

Important

D-ASA metadata is informational only, they have no influence on the contract execution and are non-normative with respect to ACTUS specifications.

Prospectus

Debt instruments are defined by their prospectus.

The D-ASA can notarize the debt instrument prospectus in the metadata.

The D-ASA prospectus hash (byte[32]) and prospectus URL (string) MAY be set on contract configuration.

The prospectus hash MUST be computed with SHA-512/256, as defined in NIST FIPS 180-4.

The digests are a single SHA-256 integrity metadata defined in the W3C subresource integrity specification. Details on generating those digests can be found on the MDN Web Docs (only SHA-256 is supported by this specification).
