Overnight.fi USD+ on Base (USD+): Uses and Risks

Overnight.fi USD+ (USD+) is a dollar-linked crypto token issued on Base. It is presented as part of Overnight Finance’s Tokens+ products: project materials describe these tokens as representing U.S. dollars and being backed by yield-generating assets. USD+ is intended to stay close to one U.S. dollar, but that target is not a guarantee that it can always be exchanged for exactly $1.

Overnight Finance describes its broader asset-management approach as using delta-neutral strategies for stablecoin-focused products. That context does not mean USD+ holders necessarily receive yield just by holding the token. The return, if any, may depend on the product’s terms and how its assets and strategies perform. USD+ is distinct from OVN, Overnight Finance’s separate utility token; USD+ is the dollar-linked asset.

USD+ may be used as a dollar-denominated asset to hold, transfer, or trade on Base, subject to wallet, exchange, and application support. Like other stablecoins, it can also be used in DeFi applications that accept it, for example as a trading or liquidity asset. Acceptance varies, and a token’s availability in a wallet does not mean a particular application supports it.

The project’s yield-generating collateral description should not be read as a promise of a fixed return to every USD+ holder. Check the specific product terms before depositing or supplying USD+ to another service. Using the token through a DeFi application can introduce additional risks beyond holding it, including the application’s smart contracts, liquidity, and any separate lending or trading strategy.

USD+ is issued on Base; it is not listed here as the native token of a blockchain. Base is an Ethereum Layer 2 network, so sending USD+ requires a wallet and transaction setup that supports Base. Make sure the receiving service accepts USD+ on Base specifically: the same ticker or token name on another network may refer to a different asset.

As of 2026-11-05, the reported circulating and total supply were each about 393,615 USD+, with no maximum supply specified. The reported price was about $0.998 and the market capitalization about $393,000 on that date. These are snapshots, not fixed values, and can change as tokens are issued, redeemed, or traded. The price has also moved away from $1 in the past, so the dollar target should not be treated as an assured peg.

USD+ carries smart-contract and network risks, including bugs, exploits, congestion, or a loss of access to Base. Its dollar target may weaken if market liquidity falls, confidence changes, or the assets and strategies supporting the product do not perform as intended. The token’s backing and any redemption process are also important to understand: do not assume that every holder can redeem instantly or at exactly one dollar. Verify current terms and available redemption routes before relying on them.

To hold USD+, use a wallet that supports Base and take care to select the correct network and token. Confirm the token’s identity using reliable project information rather than relying on a ticker alone. Protect your recovery phrase and private keys, and never share them to obtain help or complete a transaction. A self-custody wallet gives you control of the keys but also makes you responsible for their security; a custodial service adds risks tied to that provider.
