case class Blueprint(preamble: Preamble, validators: Seq[Validator] = ...)

A CIP-57 compliant description of a set of validators.

A CIP-57 compliant description of a set of validators.

Each validator description contains schemas PlutusDataSchema of the datum and redeemer formats expected by the contracts.

Type class for types that can provide a TypeDescription for CIP-57 blueprints.

Type class for types that can provide a TypeDescription for CIP-57 blueprints.

Instances of this type class are used to generate datum, redeemer, and parameter schemas in Blueprint validators.

Type parameters

The description of the data shape of a validator parameter, datum or redemeer.

The description of the data shape of a validator parameter, datum or redemeer.

For user types, the schema should generally be PlutusDataSchema.derived as opposed to manually assembled.

If assembled directly, it should be compliant with https://cips.cardano.org/cip/CIP-57.

Namely, composite types should be represented as DataType.Constructors, with properly indexed fields, tuples of arity >3 should be DataType.Lists with respective items, and pairs should be DataType.PairBuiltin. See BlueprintTest for derivation examples and expectations.

DataType for type description

scalus.builtin.Data for more info about onchain data types

Note

the types described by these schemas are used as datums, redeemers and parameters. As such, only onchain data should be described by PlutusDataSchema. Therefore, attempting to derive schemas for types that cannot be on chain will lead to compile time errors. Generally, if one can derive scalus.builtin.Data.FromData for a type, one can also do so for the schema. If one cannot derive scalus.builtin.Data.FromData, it means that the type cannot exist on chain, and therefore should not be described with PlutusDataSchema
