    • metadata object | null

      ⚠️ WARNING ⚠️

      Please note that metadata provided in a transaction will be stored on the blockchain forever. Make sure not to include any sensitive data, in particular personally identifiable information (PII).

      Extra application data attached to the transaction.

      Cardano allows users and developers to embed their own authenticated metadata when submitting transactions. Metadata can be expressed as a JSON object with some restrictions:

      1. All top-level keys must be integers between 0 and 2^64 - 1.

      2. Each metadata value is tagged with its type.

      3. Strings must be at most 64 bytes when UTF-8 encoded.

      4. Bytestrings are hex-encoded, with a maximum length of 64 bytes.

      Metadata aren't stored as JSON on the Cardano blockchain but are instead stored using a compact binary encoding (CBOR).

      The binary encoding of metadata values supports three simple types:

      • Integers in the range -(2^64 - 1) to 2^64 - 1
      • Strings (UTF-8 encoded)
      • Bytestrings

      And two compound types:

      • Lists of metadata values
      • Mappings from metadata values to metadata values

      It is possible to transform any JSON object into this schema.

      However, if your application uses floating point values, they will need to be converted somehow, according to your requirements. Likewise for null or bool values. When reading metadata from chain, be aware that integers may exceed the javascript numeric range, and may need special "bigint" parsing.

    • script_validity string | null

      Indicates whether the phase-2 monetary policy script (e.g. Plutus script) used in the transaction validated or not. Validity may be null if this transaction was from an era that doesn't support phase-2 monetary policy scripts, or is a pending transaction (we don't know if validation passed or failed until the transaction hits the ledger).

      Values are valid or invalid.

          Value is slot.

    • witness_count object Required

      Specifies the number of verification key and bootstrap wintesses. As scripts act as witnesses they are also included. Scripts can be specified and spent in a given transaction or defined to be consumed later. In the latter case they are defined in transaction outputs (feature possible from Babbage era) in one transaction and referenced in other later transaction(s). The script referencing is realized via including of reference in a reference input. If reference script is present here it included the form of the script and reference to be used later, ie. tx id and index of tx out where the script was included.
