      • assets array[object]

        A flat list of assets (possibly empty).

        An asset on the Cardano blockchain. An asset is uniquely identified by its policy_id and asset_name (together, these form the asset id).

        Two assets with the same asset_name and policy_id are interchangeable. Yet, different assets with a same policy_id but different asset_name are treated as separate assets, as are two assets with the same asset_name but different policy_id.

        Hide assets attributes Show assets attributes object
        • policy_id string(hex) Required

          A unique identifier of the asset's monetary policy. The policy controls how assets of this kind are created and destroyed.

          The contents are the blake2b-224 hash of the monetary policy script, encoded in hexadecimal.

          The asset on-chain type which acts as a sub-identifier within a policy. Although we call it "asset name", the value needn't be text, and it could even be empty.

          For policies with a single fungible asset item, asset name is typically an empty string.

          This value can be up to 32 bytes of arbitrary data (which is 64 hexadecimal digits).

          Maximum length is 64.

        Minimum value is 0.

    • outputs array[object] Required

      A list of target outputs with amounts specified.

      When creating a new transaction, the wallet software ensures that all user-specified transaction outputs have ada amounts that satisfy the ledger minimum UTxO rule:

      • If a user-specified transaction output has an ada amount that is zero, the wallet software will automatically assign a minimal amount of ada to the output so that it satisfies the ledger minimum UTxO rule.

      • If a user-specified transaction output has an ada amount that is non-zero, the wallet software will verify that the specified amount is large enough to satisfy the ledger minimum UTxO rule. If the amount is not large enough, the wallet software will return a utxo_too_small error, together with a revised ada amount that does satisfy the minimum UTxO rule.

      At least 0 elements.

    • 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.

      Any of:
      full object | null simple object | null
    • 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.

Note that it is generally not okay to use this fingerprint as a unique identifier for it is not collision resistant. Yet within the context of a single wallet, it makes for a (rather) short user-facing comparison mean.

            Minimum length is 44, maximum length is 44. Format should match the following pattern: ^(asset)1[0-9a-z]*$.

      • wallet_policy_key_hash string(bech32)

        Format should match the following pattern: ^((policy_vk)|(policy_vkh))1[0-9a-z]*$.

      • wallet_policy_key_index string

        An individual segment within a derivation path.

        The H suffix indicates a Hardened child private key, which means that children of this key cannot be derived from the public key. Indices without a H suffix are called Soft.
