Ethereum Holds Less Than Half the Onchain Dollar — and Nearly a Third of It Lives on Tron
Of the roughly US$288 billion in major dollar stablecoins we measure, Ethereum holds 48.7% — less than half. Nearly a third, US$93 billion, sits on Tron. And the two chains are opposite in kind: Ethereum's supply is spread across a dozen-plus issuers, while Tron's is 98.6% a single token, Tether's USDT. The onchain dollar has split by function — and the buzzy new chains barely register.

The onchain dollar is usually described as an Ethereum story. Measured across the major stablecoins, it isn't. Of the roughly US$288 billion we track, Ethereum holds 48.7% — less than half. The chain most associated with stablecoins is a minority of the dollar that runs on chains. Nearly a third of it, about US$93 billion, sits on Tron.
These are not two versions of the same thing. Ethereum's US$141 billion is spread across a dozen-plus issuers — USDT, USDC, USDS, DAI, USDe, PYUSD, RLUSD and others. Tron's US$93 billion is, to 98.6%, a single token: Tether's USDT. One chain hosts a competitive market of dollars; the other is, in practice, one dollar.
A financial center and a payments rail
The split is not accidental. Ethereum is where the dollar goes to do things — serve as collateral, settle across DeFi, move between the many issuers competing for the same onchain economy. Tron is where the dollar goes to move: cheap, fast USDT transfers that dominate remittance and emerging-market payment corridors, where one trusted token is worth more than a menu of them. The onchain dollar has bifurcated by function, and the chain map is the fingerprint of that divide — a diversified market on one chain, a single settlement asset on the other.

Ethereum, a minority; Tron, a third
Major dollar stablecoin supply by chain, in US$ billions. Ethereum (green) holds the largest share, but at 48.7% it is less than half; Tron holds nearly a third, almost entirely as USDT. The two plus Solana account for 85.5% of the total. Figures are the major dollar stablecoins we measure, reconciled to independent market value.
The new chains barely register
This is the context the multichain story tends to leave out. The chains that fill the headlines — Base, Hyperliquid, Robinhood Chain — are, at the aggregate, rounding errors. Base holds 1.6% of the onchain dollar; Robinhood Chain, 0.3%. That does not make their growth unreal: individual issuers are actively seeding them, and Ethena spread its USDe across a dozen chains in a single month. But an issuer's choice and the market's center are different things. The money as a whole has not moved: Ethereum, Tron and Solana still hold 85% of it, and the roughly 170 other chains that carry any dollar supply together hold almost none.
So the useful question is not which new chain wins the dollar — it is whether the dollar's two functions stay split. As long as collateral and DeFi concentrate on Ethereum while payments concentrate on Tron, the onchain dollar remains a two-chain world, and the maps that look fixed today stay fixed. The moment a single chain does both jobs cheaply — deep DeFi and cheap settlement at once — or a new entrant does, the structure that has held for years becomes the thing that moves.
Across the major dollar stablecoins we measure (~US$288B), Ethereum holds US$140.5B (48.7%), Tron US$93.1B (32.3%), and Solana US$12.8B (4.4%) — the three together 85.5%. A long tail of roughly 170 further chains holds the remainder. Figures are all-chains stablecoin supply, reconciled to independent market value.
Verified Aug 27, 2026 · onchainbenchmark.com/methodologyEthereum's US$141B is spread across a dozen-plus stablecoin issuers (USDT, USDC, USDS, DAI, USDe, PYUSD, RLUSD and others); its two largest, USDT and USDC, are about 83% of it. Tron's US$93B is 98.6% a single token, Tether's USDT (plus a small amount of USDD). One chain hosts a competitive market of dollars; the other, in practice, one.
Coverage notes · onchainbenchmark.com/methodologyThis measures the major dollar stablecoins (~US$288B), about 93% of the external ~US$310B stablecoin market; the remainder is a tail of small stablecoins. The finding is robust to that gap: adding every missing stablecoin, Ethereum's share is 48.5% — still a minority. 'Diversified' means many issuers present, not evenly spread. The functional reasons (Tron as a payments rail, Ethereum as a DeFi center) are established context, not measurements.
Coverage notes · onchainbenchmark.com/methodology- Do most stablecoins live on Ethereum?
- No. Of the roughly US$288 billion in major dollar stablecoins we measure, Ethereum holds 48.7% — a minority. Nearly a third, about US$93 billion, sits on Tron, and Solana holds another 4%. Ethereum is the single largest chain for stablecoins, but it holds less than half of them. The finding holds even against the full market: adding the stablecoins we don't measure, Ethereum's share is about 48.5%.
- Why does Tron hold so many dollars?
- Tron's roughly US$93 billion is 98.6% a single token — Tether's USDT — and it functions as a payments rail: cheap, fast USDT transfers that dominate remittance and emerging-market corridors, where one widely trusted token is more useful than a variety of them. Ethereum, by contrast, hosts a dozen-plus competing issuers because its dollar is used as collateral and across DeFi. The onchain dollar has split by function.
- Aren't stablecoins moving to new chains like Base and Robinhood Chain?
- Individual issuers are — Ethena spread its USDe across a dozen chains in a single month. But at the aggregate the new chains barely register: Base holds about 1.6% of the onchain dollar and Robinhood Chain 0.3%. Ethereum, Tron and Solana still hold 85% of it. The money as a whole has not moved, even as specific issuers place supply on newer networks.
