Asset Transfer Transaction

Fields

An asset transfer transaction additionally has the following fields:

FIELD	CODEC	TYPE	REQUIRED
Asset ID	`xaid`	`uint64`	Yes
Asset Amount	`aamt`	`uint64`	No
Asset Sender	`asnd`	`address`	No
Asset Receiver	`arcv`	`address`	Yes
Asset Close-to	`aclose`	`address`	No

The asset ID $ \Asset_\mathrm{xfer,ID} $ identifies the asset being transferred.

The asset amount $ \Asset_a $ (OPTIONAL) indicates the number of asset units being transferred.

If the asset amount is omitted ($ \Asset_a = 0 $), the number of asset units transferred is zero.

The asset sender $ \Asset_I $ (OPTIONAL) identifies the source address for the asset transfer (non-zero if the transaction is a clawback).

If the asset sender is omitted ($ \Asset_I = 0 $), the source address of the asset transfer is the sender of the transaction.

The asset receiver $ \Asset_{I^\prime} $ identifies the destination address for the asset transfer.

The asset close to address $ \Asset_{I_0}$ (OPTIONAL) collects all remaining asset units in the sender account after the asset transfer.

If the asset close to address is omitted ($ \Asset_{I_0}$), the field has no effect.
