In short
A fiat-backed stablecoin is issued against cash and short-term government debt that the issuer holds in reserve. The price stays near one dollar because buyers believe those reserves exist and can be claimed. Stability therefore rests on the issuer's balance sheet and its willingness to redeem, not on any property of the blockchain.
Key points
- Tokens are issued against cash and short-term government debt
- Stability depends on the issuer's reserves and redemption policy
- What backs each coin, and who audits it, varies by issuer
- Recovery is not guaranteed if the issuer fails or is frozen
Definition
A stablecoin whose issuer holds fiat-denominated assets in reserve and mints tokens in proportion to them. The backing sits off-chain, in the issuer's custody, not on the blockchain itself.
The mechanism is simple. A user or trading firm sends cash to the issuer, and the issuer mints an equivalent amount of tokens on-chain. Send the tokens back and the cash returns. As long as that round trip works, the market price has little room to drift far from the value of the reserves.
What sits in reserve differs from issuer to issuer. Some hold only bank deposits; others include short-term government paper, repurchase agreements or commercial paper. The longer the maturity and the thinner the liquidity, the greater the chance that a rush of redemptions cannot be met on time.
For the holder, the balance is both an on-chain entry and a claim on a company. However correct the chain record is, that claim loses value if the issuer's assets are impaired, its bank accounts are frozen, or a regulator halts its business. The real risk lives off-chain.
Watch out for
- · Being dollar-denominated does not make the balance risk-free; issuer risk never goes away
- · Reserve composition differs by issuer — read the published disclosures yourself
- · Held on an exchange, a stablecoin carries both issuer risk and exchange risk
