Enum Asset 

pub enum Asset {
    Xch,
    Cat(AssetId),
}

The asset a wallet balance/coin read is denominated in: native XCH, or any CAT by asset id.

Why there is no separate Dig variant

$DIG is a CAT, so it is Asset::DIG — an associated constant, not a variant. A three-variant {Xch, Dig, Cat(id)} would give $DIG two INEQUAL spellings, and a balance or coin list filtered by one of them would silently omit everything carrying the other: a wallet reporting half a balance as though it were the whole. One token, one value.

Wire form (additive — CLAUDE.md §5.1)

Value	JSON
Asset::Xch	"xch"
Asset::DIG	"dig"
any other CAT	{"cat":"<64-hex>"}

Both legacy tokens are still ACCEPTED and "dig" is still EMITTED, so a node or client built before this release keeps understanding, and being understood by, one built after it. {"cat":"<the $DIG asset id>"} is also accepted and normalizes to Asset::DIG.

Byte-identical to dig-app’s consumer type (dig-app-core::wallet::state::Asset), recorded in the canonical skill so the two implementations cannot drift.

Variants

Xch

Native Chia (XCH), denominated in mojos.

Cat(AssetId)

A CAT, named by its asset id and denominated in its own base units.

Implementations

impl Asset

pub const DIG_ASSET_ID_HEX: &'static str = "a406d3a9de984d03c9591c10d917593b434d5263cabe2b42f6b367df16832f81"

Canonical $DIG CAT asset id (TAIL hash) on Chia mainnet, as lowercase hex.

CONTRACT: byte-identical to dig_constants::DIG_ASSET_ID, chip35_dl_coin::DIG_ASSET_ID, and digstore-chain’s. It is duplicated here rather than imported because this crate is a level-00 foundation crate and may not depend sideways on dig-constants (CLAUDE.md Appendix B). dig_asset_id_hex_and_bytes_are_the_same_id pins THIS crate’s two spellings of it together; agreement with the ecosystem constant is a source-of-truth obligation on whoever changes it, recorded in the canonical skill.

pub const DIG: Asset

$DIG, the CAT every capsule payment is denominated in.

pub fn is_dig(&self) -> bool

Whether this asset is $DIG, however it was spelled on the wire.

pub fn asset_id(&self) -> Option<&AssetId>

The CAT asset id, or None for native XCH.
