CredentialCreate Transaction

A CredentialCreate transaction creates a credential in the ledger. The issuer of the credential uses this transaction to provisionally issue a credential. The credential is not valid until the subject of the credential accepts it with a CredentialAccept transaction.

Example CredentialCreate JSON

    "Fee": "10",
    "Flags": 0,
    "Sequence": 234200
}

CredentialCreate Fields

In addition to the common fields, CredentialCreate transactions use the following fields:

Field	JSON Type	Internal Type	Required?	Description
`Subject`	String - Address	AccountID	Yes	The subject of the credential.
`CredentialType`	String - Hexadecimal	Blob	Yes	Arbitrary data defining the type of credential this entry represents. The minimum length is 1 byte and the maximum length is 64 bytes.
`Expiration`	Number	UInt32	No	Time after which this credential should be considered expired, in seconds since the Ripple Epoch.
`URI`	String	Blob	No	Arbitrary additional data about the credential, such as the URL where users can look up an associated Verifiable Credential document. If present, the minimum length is 1 byte and the maximum is 256 bytes.

The Account field (the sender) of the transaction is the issuer of the credential. It is possible for the issuer and the subject to be the same account.

Error Cases

Besides errors that can occur for all transactions, CredentialCreate transactions can result in the following transaction result codes:
