• id and height should be omitted when broadcasting. These fields are set by the node.
• Binary strings are base58 encoded.
• timestamp is in microseconds since epoch.
• fee and amount include 8 digits, so LTO * 10^8 {% endhint %}

Binary schema

The binary data structure of the unsigned transaction.

{% tabs %} {% tab title="V3 (current)" %}

#	Field Name	Type	Length
1	Transaction type	Byte (constant, value=8)	1
2	Version	Byte (constant, value=3)	1
3	Network id	Byte	1
4	Timestamp	Long	8
5	Sender's key type	KeyType (Byte)	1
6	Sender's public key	PublicKey (Array[Byte])	32 | 33
7	Fee	Long	8
8	Recipient	Address (Array[Byte])	26
9	Amount	Long	8

{% hint style="info" %}

• 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. {% endhint %} {% endtab %}
