What is oneusd?

Could you please clarify what you mean by "oneusd"? Is it a reference to a specific cryptocurrency or financial instrument? If so, I'm not immediately familiar with a cryptocurrency or financial product named exactly "oneusd." Could you provide more context or explain the context in which you came across this term? Alternatively, are you perhaps referring to a stablecoin pegged to the value of the United States dollar, as many stablecoins are designed to maintain a stable value relative to a fiat currency like the USD? In that case, the specific name "oneusd" may be unique to a particular project or platform.
