What USD+ actually is on-chain

Overnight.fi USD+ (Base) is an ERC-20 deployed on Base, at contract address 0xb79dd08ea68a908a97220c76d19a6aa9cbde4376. That address, not the ticker USD+, is what uniquely identifies this asset: anyone can deploy a second token calling itself USD+, but the contract is unforgeable. Verify it against basescan.org before sending funds or approving a spend.

Because it lives on Base, USD+ is held in any EVM-compatible wallet, transfers are paid for in ETH rather than in USD+ itself, and secondary liquidity sits in Aerodrome and Uniswap 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 USD+: USD+ (Solana, usdsfJ…dUia). The asset on this page is specifically the Base deployment at 0xb79d…4376. 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 USD+ the project publishes a whitepaper, a public source repository and an active account as @overnight_fi. Both a written specification and readable code exist, which is a materially higher bar than most assets in this size range clear. 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 USD+ sits in the market

Overnight.fi USD+ (Base) ranks #3513, 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 USD+ 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. USD+ is a Base asset, so whatever turnover exists is most likely in Aerodrome and Uniswap pools rather than on a centralised book, and every fill there costs ETH in gas on top of the pool's own fee.

USD+ against its all-time high

Overnight.fi USD+ (Base)'s record high is $2.00, set on 2025-04-27. 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. It was set roughly 2 years ago, so it belongs to the current cycle but not to current conditions. We are not quoting a drawdown from it because no tracked venue is giving us a live USD+ price — a stale or single-pool number would make that percentage look precise when it is not.

USD+ across its historical range

The recorded range is comparatively narrow: 2.16x between $0.9239 and $2.00. Either the price history is short, or the asset is designed not to move.

The record low of $0.9239 was printed on 2025-10-10 — about a year ago. We have no live quote to measure the current distance from it.

USD+ supply and valuation data

Supply figures for USD+ 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 $511 thousand as of 2026-05-11. That sits around the middle of the distribution — roughly half the assets tracked here carry a smaller fully diluted value.

Since the figure is a snapshot rather than a live number, we do not reverse it into a supply count: the price has moved since it was taken, and that division would produce a confident but incorrect token count. For any per-token valuation, check the current supply on the project's own explorer first. The authoritative figure is the one basescan.org reports for this contract.

What kind of asset USD+ is

Overnight.fi USD+ (Base) 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. It is backed by off-chain reserves, which moves the risk from smart-contract code to custody and disclosure: who holds the reserves, what they are held in, and how often that is attested. Those are the questions that decide whether the peg survives a redemption wave. It is small for a stablecoin, and at this size the peg depends heavily on one or two liquidity pools; thin-book depegs here say more about liquidity than about solvency.

CoinGecko files USD+ under 5 categories, including Stablecoins, USD Stablecoin, Base Ecosystem, Fiat-backed Stablecoin, Base Native.
