Asset Configuration Transaction

Fields

An asset configuration transaction additionally has the following fields:

FIELD	CODEC	TYPE	REQUIRED
Asset ID	`caid`	`uint64`	Yes (except for Creation)
Asset Parameters	`apar`	`struct`	Yes (for Creation)

Asset ID

The asset ID $ \Asset_\mathrm{cfg,ID} $ identifies the asset being configured.

If the asset ID is omitted (zero), this transaction is creating an asset.

Asset Parameters

The asset parameters are the parameters for configuring the asset.

These asset parameters is structure containing:

FIELD	CODEC	TYPE	DESCRIPTION
Total	`t`	`uint64`	Total amount of units of the asset
Decimals	`dc`	`uint32`	Number of digits after the decimal place
Default Frozen	`df`	`bool`	Flag that specifies if the asset requires whitelisting (yes if `true`)
Unit Name	`un`	`string`	Asset unit symbol (or asset short-name)
Asset Name	`an`	`string`	Asset name
URL	`au`	`string`	URL to retrieve additional asset information
Metadata Hash	`am`	`[32]byte`	Commitment to asset metadata
Manager	`m`	`address`	Account allowed to set the asset role-based access control and destroy the asset
Reserve	`r`	`address`	Account whose asset holdings should be interpreted as “not mined” (this is purely a label)
Freeze	`f`	`address`	Account allowed to change the account’s frozen state for the asset holdings
Clawback	`c`	`address`	Account allowed to transfer units of the asset from any account

The decimals MUST NOT exceed $ \MaxAssetDecimals $.
The unit name byte length MUTS NOT exceed $ \MaxAssetUnitNameBytes $.
The asset name byte length MUST NOT exceed $ \MaxAssetNameBytes $.
The URL byte length MUST NOT exceed $ \MaxAssetURLBytes $.

If the asset parameters are omitted (struct of zero values), this transaction is deleting the asset.
