AssetTypeCreditAlphanum12
extends AssetTypeCreditAlphanum
in package
Represents an issued asset with a 5-12 character alphanumeric code
AlphaNum12 assets are identified by a longer code (5-12 characters) and the issuer's account ID. These are used for assets with longer names like MYCOIN, TOKENXYZ, etc.
Usage:
$token = new AssetTypeCreditAlphanum12("MYTOKEN", "GISSUER...");
// or use the factory method
$token = Asset::createNonNativeAsset("MYTOKEN", "GISSUER...");

Methods
__construct()
Creates an AlphaNum12 asset with code validation
public
__construct(string $code, string $issuer) : mixed
Parameters
- $code : string
-
Asset code (5-12 characters)
- $issuer : string
-
Issuer account ID (public key starting with G)
Tags
canonicalForm()
Returns the canonical string representation of an asset
public
static canonicalForm(Asset $asset) : string
Format:
- Native: "native"
- Issued: "CODE:ISSUER" (e.g., "USD:GABC...")
Parameters
- $asset : Asset
-
The asset to convert
Tags
Return values
string —The canonical form
create()
Creates an asset from its type, code, and issuer
public
static create(string $type[, string|null $code = null ][, string|null $issuer = null ]) : Asset
Pool share assets cannot be created here because they are composed of two assets rather than a code and issuer; construct an AssetTypePoolShare directly.
Parameters
- $type : string
-
TYPE_NATIVE, TYPE_CREDIT_ALPHANUM_4 or TYPE_CREDIT_ALPHANUM_12
- $code : string|null = null
-
Asset code (required for non-native assets)
- $issuer : string|null = null
-
Issuer account ID (required for non-native assets)
Tags
Return values
Asset —The created asset
createFromCanonicalForm()
Creates an asset from its canonical string representation
public
static createFromCanonicalForm(string $canonicalForm) : Asset|null
Accepted formats:
- "native" or "XLM" for native XLM
- "CODE:ISSUER" for issued assets (e.g., "USD:GABC...")
Parameters
- $canonicalForm : string
-
The canonical asset string
Return values
Asset|null —The created asset, or null if the format is invalid
createNonNativeAsset()
Creates a non-native asset with automatic type detection based on code length
public
static createNonNativeAsset(string $code, string $issuer) : AssetTypeCreditAlphanum
The asset type (AlphaNum4 or AlphaNum12) is determined automatically based on the length of the asset code.
Parameters
- $code : string
-
Asset code (1-12 characters)
- $issuer : string
-
Issuer account ID (public key starting with G)
Tags
Return values
AssetTypeCreditAlphanum —The created asset (AlphaNum4 or AlphaNum12)
fromJson()
Creates an asset from JSON data (typically from Horizon responses)
public
static fromJson(array<string|int, mixed> $json) : Asset
Parameters
- $json : array<string|int, mixed>
-
JSON data with asset_type, asset_code, and asset_issuer fields
Return values
Asset —The created asset
fromXdr()
Creates an Asset from its XDR representation
public
static fromXdr(XdrAsset $xdrAsset) : Asset
Parameters
- $xdrAsset : XdrAsset
-
The XDR asset data
Tags
Return values
Asset —The reconstructed asset
fromXdrChangeTrustAsset()
Creates an Asset from its XDR ChangeTrustAsset representation.
public
static fromXdrChangeTrustAsset(XdrChangeTrustAsset $xdrAsset) : Asset
Handles all asset types including POOL_SHARE.
Parameters
- $xdrAsset : XdrChangeTrustAsset
-
The XDR change trust asset data
Tags
Return values
Asset —The reconstructed asset
fromXdrTrustlineAsset()
Creates an Asset from its XDR TrustlineAsset representation.
public
static fromXdrTrustlineAsset(XdrTrustlineAsset $xdrAsset) : Asset
Handles NATIVE, CREDIT_ALPHANUM4, and CREDIT_ALPHANUM12. POOL_SHARE trustline assets contain only a pool ID hash and cannot be reconstructed into an AssetTypePoolShare (which requires both reserve assets).
Parameters

-
The XDR trustline asset data
Tags
Return values
Asset —The reconstructed asset
getCode()
Returns the asset code
public
getCode() : string
