Cryptocurrencies in the ranking grouped by the shape of the ledger they run — one native asset, one plus overlay tokens, or multi-asset from the ground up — 484 chains across 3 ledger type categories, $2.08T combined.
Chains that carry one native asset and nothing else.
Chains that carry a native asset AND an overlay layer for tokens defined by convention or contract — Bitcoin's SLP or Runes, Ethereum's ERC-20.
Chains designed from day one to carry multiple assets natively — Stellar and XRP Ledger let anyone issue an asset, and the ledger treats it as first-class.
Categories are curated in-house — see methodology for the definitions. A chain without a stated ledger type on its own page is not filed under one here either.
