• id and height should be omitted when broadcasting. These fields are set by the node.

• recipient andsubject are optional.

• Binary strings are base58 encoded.

• timestamp is in microseconds since epoch.

• fee includes 8 digits, so LTO * 10^8

Data entries

Statement transactions can have data entries. These are similar to those of the data transaction.

Binary schema

The binary data structure of the unsigned transaction.

4	Timestamp	Long	8
5	Sender's key type	KeyType (Byte)	1
6	Sender's public key	PublicKey (Array[Byte])	32 | 33

• Network id can be obtained by taking the 2nd byte from the sender address.

• Each key type has a numeric id in addition to the reference from the JSON.

• Integers (short, int, long) have a big endian byte order.

The encoding of a data entry depends on the type. For more information see "Binary schema of data entries".
