A fiat-backed stablecoin is the simplest idea in crypto, and the one Ian King’s Dollar Reboot pitch is built on: a token that is supposed to always be worth one U.S. dollar because a dollar of real assets sits behind it. The mechanics are worth understanding, because the whole “6% interest” hook depends on how these reserves actually work. Our How Omnichain Stablecoins Work, and Why Musk Needs Them explainer covers this in detail.
The Reserve Model
A fiat-backed stablecoin works like a money-market fund wearing a token costume. The issuer takes in a dollar from you and holds a dollar of assets, mostly short-term Treasuries and cash, in reserve. It then mints one token for that dollar. When you redeem the token, the issuer sells the asset and hands you your dollar back. That is the entire mechanism: token in, asset held, token out.
The key word is “fiat-backed.” Unlike Bitcoin, which has value because people agree it does, a fiat stablecoin’s value comes from the actual dollars sitting in a bank or brokerage account somewhere. The issuer is promising the token can always be traded back for a real dollar.
Why One-to-One Backing Matters
The one-to-one ratio is what keeps the peg at $1. If the market ever doubted the reserves, the token would trade below a dollar, and the whole system would wobble. That is why the asset choice matters so much. Issuers hold Treasuries and cash precisely because they are the most liquid dollar assets in the world.
King connects this to banking in a way that is worth pausing on. Since 2020 the Federal Reserve has required banks to hold 0% reserves against deposits, meaning a bank lends out the money you deposit rather than holding it. A fully backed stablecoin, by contrast, is designed to hold the reserves outright. That is the quiet argument for why a stablecoin can pay meaningful interest while a checking account pays almost nothing: the assets behind the token actually earn a Treasury yield.
Where the Interest and FDIC Claims Fit
The presentation’s headline numbers ride on these mechanics. The claim is 6% interest, hedged in the body to “up to 4.7%,” which tracks the yield on short-term Treasuries plus whatever the platform shares back. The FDIC claim, “up to $10 million,” works differently: it is not one account insured for $10 million, it is a deposit-sweep that spreads your balance across a network of banks, each carrying the standard $250,000 of coverage.
None of this is fictional, but it is assembled for maximum headline effect. The reserves are real, the Treasury yield is real, and the sweep structure is real. The friendliest possible framing of those three facts is the cold open. Our full teardown quotes the exact language.
How It Differs From Algorithmic Coins
The contrast that keeps coming up in the pitch is with algorithmic stablecoins, which hold no real collateral and instead use code to try to keep a peg. Those have failed spectacularly in the past, and King’s presentation is careful to draw the line: fiat-backed coins are different because the dollars are actually there.
That is the correct answer and it builds trust. A fiat-backed stablecoin’s risk is not “the peg breaks for no reason,” it is “can the issuer keep the reserves liquid and honest.” This simple definition piece covers the wider category, and the earlier Stansberry pitch is useful contrast for how the same idea gets stretched.
What Happens When a Stablecoin Breaks
The reason the fiat-backed design matters so much is the history of the alternatives. Algorithmic stablecoins, which hold little or no collateral and rely on code to keep a peg, have failed publicly, with one high-profile collapse wiping out tens of billions in value almost overnight. A fiat-backed coin is not immune to stress, but its failure mode is different and generally more contained.
The risk for a fiat-backed coin is a reserve run. If holders all try to redeem at once and the issuer cannot liquidate its Treasury holdings fast enough, the peg can crack even though the assets are real. That is why the asset choice, short, liquid Treasuries, matters: they can be sold in any market condition, which is the buffer against a run.
This is also why King’s pitch frames stablecoins as fundamentally different from the meme coins. The difference is not vibes, it is a balance sheet. A fiat-backed stablecoin either has the dollars or it does not, and that is an answer you can verify with an audit. It is the closest thing the crypto world has to boring, and in this context boring is the selling point.
