Ring USD USDR

What USDR actually is on-chain

Ring USD is an ERC-20 deployed on Ethereum, at contract address 0x4EA40dcee961675683e0a2e1721Bd49CB9bca913. That address, not the ticker USDR, is what uniquely identifies this asset: anyone can deploy a second token calling itself USDR, but the contract is unforgeable. Verify it against etherscan.io before sending funds or approving a spend.

Because it lives on Ethereum, USDR is held in any EVM-compatible wallet, transfers are paid for in ETH rather than in USDR itself, and secondary liquidity sits in Uniswap-style AMM pools. Two consequences follow for anyone setting alerts: you need ETH in the same wallet to move the token at all, and a quoted price taken from a pool is a pool price — it includes slippage that an order-book quote would not.

Another asset tracked on this site also uses the ticker USDR: StablR USD (Ethereum, 0x7B43…C8f8). The asset on this page is specifically the Ethereum deployment at 0x4EA4…a913. These are unrelated tokens with separate contracts, separate supply and separate price histories — a price alert set on one of them says nothing about the others, and a ticker search is not enough to tell them apart.

For USDR the project publishes an active account as @ProtocolRing. That is a partial paper trail — enough to check claims against, not enough to audit. None of it is a quality judgement about the asset; it is simply what can be independently checked before the chart is worth looking at.

Where USDR sits in the market

Ring USD ranks #3975, in the upper long tail, past the point where most data providers stop publishing supply figures, far outside the set of assets that carry continuous market-maker coverage. At this end of the table the first question is data integrity rather than valuation: a quote can originate from a single pool or a single venue, reported volume is difficult to verify independently, and the distance between the last print and a genuinely executable price can be wide. Treat any indicator computed on this series as provisional.

We are not currently receiving a live USDR order book from any of the exchanges connected to this site, so no real-time quote is shown above. That is itself information: it usually means the pair is unlisted on the venues we track, or trading has been halted. USDR is a Ethereum asset, so whatever turnover exists is most likely in Uniswap-style AMM pools rather than on a centralised book, and every fill there costs ETH in gas on top of the pool's own fee.

USDR against its all-time high

Ring USD's record high is $1.08, set on 2025-12-09. That high sits in a range where whole-cent and whole-unit levels are genuinely traded, which makes them usable as alert thresholds if a quote returns. The print is recent enough — about a year ago — that it still describes the market USDR trades in today. We are not quoting a drawdown from it because no tracked venue is giving us a live USDR price — a stale or single-pool number would make that percentage look precise when it is not.

USDR across its historical range

The recorded range is comparatively narrow: 1.15x between $0.9415 and $1.08. Either the price history is short, or the asset is designed not to move.

The record low of $0.9415 was printed on 2026-02-01 — about a year ago. We have no live quote to measure the current distance from it.

USDR supply and valuation data

Supply figures for USDR are self-reported at this rank rather than reconciled against the chain, so we publish the valuation we have and not a circulating-supply number we cannot check. What we do have is a fully diluted valuation of $100.4 million as of 2026-05-12. That is in the top 5% of the assets tracked on this site by fully diluted value.

Because that valuation is a snapshot rather than a live figure, we deliberately do not back out a supply number from it — the price has moved since, and the division would produce a confident-looking token count that is simply wrong. Check the project's own explorer for the current supply before using any per-token valuation. The authoritative figure is the one etherscan.io reports for this contract.

What kind of asset USDR is

Ring USD is pegged to the US dollar, so the only price question that matters is whether the peg holds; trend and momentum readings on a dollar peg describe noise, not direction. Our dataset does not record which backing model this token uses, which is itself worth resolving before holding it: reserve-backed, collateral-backed and algorithmic pegs fail in very different ways and on very different timescales. Its size is mid-range for the category — large enough to be quoted continuously, small enough that a single large redemption is visible in the price.

CoinGecko files USDR under 3 categories, including Stablecoins, USD Stablecoin, Ethereum Ecosystem. CoinGecko also records deployments on Ethereum (3,072 tracked tokens), so its on-chain liquidity and its user base move with that network.
