Taxonomy
The Foundation's group › category › assetClass tiers, with the Allium and RWA.xyz vocabularies that sit beside them.
Every registry item carries three classification views: the Solana Foundation data team's own
taxonomy in group, category and assetClass, Allium's in alliumClass, and RWA.xyz's in
rwaClass. This page lists the vocabularies as they stand today. The data team adds classes and
reclassifies assets as the market changes, so treat the counts as illustrative and read the live
values from the API rather than hard-coding them.
The Foundation taxonomy
The three tiers form a strict tree: each assetClass belongs to one category, each category to one
group. The list endpoint filters on all three (group, category, class) as case-sensitive,
exact-match values, spelled exactly as the API returns them — Fiat-Backed, not fiat-backed;
ETF / Indices with the spaces around the slash. Combine filters freely; a class filter on its own is
already unambiguous.
Counts below are the number of registry items in each class at the time of writing (3,293 in total).
Crypto Native
Assets whose value comes from a blockchain protocol rather than an off-chain claim. About 500 items.
| Category | Class | Examples |
|---|---|---|
Bridged | Bridged (156) | Tokens issued on another chain and bridged to Solana, such as wrapped ETH and wrapped BTC. |
SOL | SOL (3) | SOL itself and its wrapped-SOL mints. |
Solana Native | Solana Native (344) | Tokens issued natively on Solana — protocol, governance and community tokens such as JUP and BONK. |
RWA
Tokenized claims on real-world assets. The largest group by count, about 2,700 items, and where Allium and RWA.xyz coverage is densest.
| Category | Class | Examples |
|---|---|---|
Commodities | Metals (9) | Tokenized gold such as PAXG and Tether Gold. |
Equities | ETF / Indices (171) | Tokenized index funds and ETFs, such as an S&P 500 tracker. |
Equities | Stocks (984) | Tokenized single stocks — a tokenized Tesla or NVIDIA share. |
Fixed Income | US Treasuries (27) | Tokenized US Treasury bills and funds holding them. |
Fixed Income | Asset Backed Securities (7) | Tokenized securities backed by pools of loans or receivables. |
Fixed Income | CLOs (3) | Tokenized collateralized loan obligations. |
Fixed Income | Other Structured Credit (1,425) | Structured credit instruments outside the classes above; the bulk of the registry by count. |
Fixed Income | Non US Gov Debt (6) | Tokenized sovereign debt of governments other than the US. |
Fixed Income | Bonds (2) | Tokenized corporate and other bonds. |
Private Funds | PE/VC (18) | Tokenized private equity and venture fund interests. |
Private Funds | Private Credit (2) | Tokenized direct-lending funds. |
Private Funds | Credit Funds (7) | Tokenized funds holding diversified credit. |
Real Estate | Real Estate (14) | Tokenized property and real-estate funds. |
Tokenized Active Strategies | Tokenized Active Strategies (14) | Actively managed strategies issued as tokens. |
Stablecoins
Tokens designed to hold a fixed value against a reference currency. About 100 items.
| Category | Class | Examples |
|---|---|---|
Crypto-Backed | Crypto-Backed Stablecoins (7) | Stablecoins collateralized by on-chain assets. |
Fiat-Backed | USD Stablecoins (65) | USD-referenced stablecoins backed by fiat reserves — USDC, USDT, PYUSD. |
Fiat-Backed | LCY Stablecoins (29) | Local-currency stablecoins referencing a currency other than the US dollar, such as the euro or the Brazilian real. |
Allium classification
alliumClass is Allium's view. It is a flat, lowercase vocabulary with no
tiers, and it groups by economic exposure rather than instrument — so Allium's rates spans what the
Foundation splits into US Treasuries and other Fixed Income classes, and credit collects the
Foundation's structured-credit and private-credit classes.
alliumClass | Covers |
|---|---|
equities | Tokenized stocks, ETFs and indices. |
stablecoins | Fiat- and crypto-backed stablecoins. |
rates | Treasury and other rate-bearing instruments. |
private_funds | Tokenized fund interests. |
credit | Structured and private credit. |
commodities | Tokenized metals and other commodities. |
alliumClass is null for most crypto-native assets. alliumValueUsd is Allium's on-chain value for
the mint in USD.
RWA.xyz classification
rwaClass is RWA.xyz's view. Like Allium's it is flat, but it is finer-grained
on the credit side and uses title-case names. It classifies by product type: where the Foundation has
one Other Structured Credit class, RWA.xyz distinguishes Specialty Finance, Corporate Credit,
Asset-Backed Credit and Diversified Credit.
rwaClass | Covers |
|---|---|
Stocks | Tokenized equities. |
Stablecoins | Stablecoins. |
US Treasury Debt | Tokenized US Treasuries. |
Commodities | Tokenized commodities. |
Specialty Finance | Niche lending and receivables products. |
Corporate Credit | Tokenized corporate loans and bonds. |
Asset-Backed Credit | Credit backed by pools of assets. |
Diversified Credit | Multi-strategy credit funds. |
Real Estate | Tokenized property. |
Private Equity | Tokenized private equity and venture interests. |
Active Strategies | Actively managed tokenized strategies. |
rwaClass is null where RWA.xyz does not cover the mint. rwaValueUsd is RWA.xyz's on-chain value
for the mint in USD.
One asset, three views
USDC (EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v) shows how the views line up:
{
"group": "Stablecoins",
"category": "Fiat-Backed",
"assetClass": "USD Stablecoins",
"alliumClass": "stablecoins",
"rwaClass": "Stablecoins",
"assetId": "usd"
}The Foundation taxonomy is the one the list endpoint filters on. Allium and RWA.xyz classes are returned on every item but are not filterable; filter by the Foundation tier and read the provider classes from the results. Credit the provider when you display their class or value.
