What Is a Digital Dollar?

A digital dollar is a dollar-linked form of money that can be recorded and moved electronically. The phrase is context-dependent: it can describe privately issued USDC, a central bank digital currency, or another instrument designed around the US dollar. Peanut uses USDC for its dollar-denominated balance.

Digital Dollar Can Mean Different Things

“Digital dollar” is a category label, not one uniform legal or technical product. The issuer and the holder's claim matter more than the nickname.

• A general category: People may use the phrase for different electronic forms of dollar-linked money. The label alone does not tell you who issued it, what supports its value, or how it can be redeemed.
• Privately issued USDC: Circle issues USDC. A holder's claim depends on a private-sector issuer and its redemption arrangements rather than on a central bank.
• A central bank digital currency: The Bank for International Settlements defines a CBDC as digital money denominated in a national unit and a direct liability of the central bank. USDC is issued by Circle, so it is not a CBDC.

These forms may share a dollar reference, but they do not create the same legal relationship or risks.

How USDC Targets One Dollar

Circle states that USDC is redeemable 1:1 for US dollars. That is the issuer's redemption statement. It does not mean every purchase or sale between market participants executes at exactly one dollar.

Circle says USDC is backed by highly liquid cash and cash-equivalent assets held separately from its operating funds. It discloses reserve holdings weekly, including related issuance and redemption activity. Circle also says a Big Four accounting firm provides monthly third-party assurance that the value of reserves is greater than the amount of USDC in circulation, under AICPA attestation standards.

Those disclosures help readers assess the issuer's reserve claims, but assurance does not remove issuer, reserve, access, or market risk. On a secondary market, buyers and sellers set the available price. USDC can therefore trade above or below one dollar even while Circle states a 1:1 issuer redemption relationship.

How Peanut Uses Digital Dollars

Peanut's regular balance is denominated in USDC and displayed as USD with cents. The dollar display makes the amount easier to read in the app; it does not change who issues USDC or turn the balance into central bank money.

The regular balance sits in your own account rather than a pooled Peanut account. Your passkey is used to control that account, and Peanut does not hold your key. This security model concerns control of the account. It is separate from Circle's role as the issuer of USDC and from the market price available when USDC is exchanged.

What to Consider

Three different dependencies are worth separating:

1. Issuer and redemption: Circle's 1:1 statement depends on Circle, its reserves, its redemption arrangements, and the access rules that apply to a redemption.
2. Market price: A sale through another venue is a secondary-market trade. Its available price can differ from the issuer's stated redemption value.
3. Account access: You control your Peanut account with a passkey. Protecting that passkey and keeping a recoverable device setup are your responsibility. If the passkey cannot be recovered, Peanut cannot restore access from a server-side copy.

Calling each of these arrangements a “digital dollar” does not make their protections interchangeable.
