What is a stablecoin neobank, and how does it work?

A stablecoin neobank is a money app built on dollar stablecoins, and the name hides three separate questions. What can the app do with dollars? Who actually holds the money? What protects it if something goes wrong? This guide defines the term, compares it with a bank, an exchange and a self-custody wallet, and lists what is worth checking before using one. It is information, not investment advice.

What is a stablecoin neobank?

A stablecoin neobank is an app that gives people a dollar account built on stablecoins instead of a bank-account ledger. Its core jobs are holding dollars, sending them and spending them with a card, and some apps also offer ways to earn through separate products.

The word "neobank" describes how a service is delivered, as an app, and not a legal status. Some neobanks are run by nonbank companies, and the FDIC says that nonbank companies, including fintechs, are never covered by deposit insurance themselves. Funds sent to a nonbank "are not eligible for FDIC insurance until the company deposits them" at a bank and meets record-keeping conditions.

So "what is it?" and "who holds the money?" are two separate questions for any neobank, and the label alone answers only the first.

What is a stablecoin?

A stablecoin is a digital token whose issuer says it will hold a stable value against a currency such as the US dollar. US law gives a formal version. The GENIUS Act (Public Law 119-27) defines a "payment stablecoin" as a digital asset used or designed to be used as a means of payment or settlement, whose issuer is obligated to convert, redeem or repurchase it for a fixed amount of monetary value and represents that it will maintain a stable value relative to that amount.

The issuer, not the app, makes that redemption promise. Circle, which issues USDC, describes it as a dollar-backed digital currency that is redeemable 1:1 for US dollars, and says that Circle Mint, the route for direct redemption, is open to institutions, not to individuals or small businesses. For an individual, that means reaching the coin through an app, an exchange or a wallet rather than through Circle Mint. Circle also says it discloses its reserve holdings weekly, which is the kind of issuer reporting worth reading for any stablecoin.

Rules for stablecoins differ by region. The US GENIUS Act was approved on 18 July 2025, and the EU's MiCA regulation has applied to e-money tokens since 30 June 2024. Neither regime is a statement about any particular app or coin, and this guide does not assess whether any app or coin meets either one.

A stablecoin does not pay interest by itself. The GENIUS Act says no permitted or foreign payment stablecoin issuer may pay the holder any form of interest or yield "solely in connection with the holding, use, or retention" of the coin, and the EU's MiCA regulation says issuers of e-money tokens shall not grant interest. Any yield an app shows therefore comes from a separate product with its own provider, terms and risks. The guide where stablecoin yield comes from explains the main sources, and the stablecoin yield hub collects the rest.

How is a stablecoin neobank different from a bank, an exchange or a wallet?

The differences come down to what you hold, who controls it and which protections apply. The table compares the four.

In practice the columns blur. A stablecoin neobank can be custodial, like an exchange, or built on wallets that the user controls. The custody model is a design choice of each app, which is why it is the first thing worth checking. The guide custodial vs non-custodial covers the difference in detail.

What can a stablecoin neobank do?

A stablecoin neobank lets you hold, send and spend dollars, and some add a way to earn. Each job can involve a different provider.

• Hold. Dollars as stablecoins such as USDC, issued by Circle, or USDT, issued by Tether. The issuer, not the app, stands behind the coin's redemption promise, so the issuer's own terms and reserve information matter.
• Send. Transfers to another person or address. The receiving address expects a specific network, and a mismatch can lose the funds, so the details matter. The guide on moving USDC from an exchange to self-custody walks through them.
• Spend. Payments with a card that draws on the stablecoin balance. A card adds an issuing partner, identity checks and regional limits, which the stablecoin card page covers.
• Earn. Returns from separate products, not from the stablecoin. Rates on such products are variable, and how to read a variable rate explains what that label means.

Not every app offers all four. A feature list works best as a list of questions: for each feature, which company provides it, and under which terms?

Who holds the money in a stablecoin neobank?

It depends on the app, and the answer decides who controls the funds. In a custodial design, a company holds the keys that control the funds and the user relies on that company. In a non-custodial design, the user alone controls the keys that move the funds. ethereum.org draws the contrast: with an exchange account "you're trusting that exchange with custody over your funds," while wallet providers "don't have custody of your funds."

Each design puts the risk in a different place. With a custodial app, the risk is the company, including its solvency and its controls. With a non-custodial app, more responsibility sits with the user, who has to protect access to the account. Neither design changes what the underlying stablecoin is, so the issuer's promise matters in both.

How does Neovestor handle these pieces?

Neovestor is software that connects you to self-custodial wallets and to third-party protocols and issuers. Every asset screen names its issuer or counterparty, links the issuer's terms and shows jurisdiction restrictions. Here is how that shows up in the pieces above.

• Keys. In Neovestor, signing in creates a Solana wallet and an Ethereum-compatible wallet for Base. Only you can approve transactions, and Neovestor can't access your keys.
• Money actions. Each one follows the same steps: a quote, a review screen, a Face ID or passcode confirmation, your signature, then status tracking.
• Fees. Network fees on Solana trades, earn deposits and sends are covered within fair-use limits, and some cross-chain transfers carry a small network or forwarding fee. A platform fee, if one applies, shows as a separate line before you confirm.
• Cash. Cash is one balance made of idle USDC plus a Cash earn position through Jupiter Lend. Every Earn rate is labeled variable and shows an "as of" time.
• Card. The Neovestor card is coming soon, with no date. It is funded from Cash, offered in eligible regions through a card-issuing partner, and identity verification is required to apply.
• Copilot. Copilot explains how the app works and answers portfolio questions. It does not place trades or recommend them, and its footer reads "Information, not advice."

What is worth checking before using a stablecoin neobank?

Five checks cover the main questions: who holds the keys, which protections apply, who issues the coin, how earning and fees are shown, and where the service is available.

1. Who holds the keys? Find out whether the app is custodial or non-custodial, and what the app says happens to the funds if the company stops operating.
2. Which protections apply? Stablecoin balances are not covered by deposit insurance, and nonbank apps are not covered themselves. Look for how the app describes this in its own terms.
3. Who issues the stablecoin? Name the issuer, read its terms and see how it reports on its reserves.
4. How are earning and fees shown? Rates should be labeled variable and dated, and fees should appear before a transfer is confirmed.
5. Where is it available? Cards and some assets are offered only in eligible regions, so a service that works in one country may not work in another.

The label describes the features. The answers to these five questions describe the risks.
