What backs a stablecoin
4 minDifficulty Checked 2026-11-10- A stablecoin holds its value only if its issuer redeems it.
- The ledger tracks balances. It cannot see or check the backing assets.
- Fiat, crypto, commodities or financial instruments can back a token.
A stablecoin is a token that is meant to stay equal to something outside the ledger, usually one unit of a currency. One token, one dollar.
It works like a coat check. You hand over a dollar. You get a ticket. Later you hand the ticket back and get the dollar. The ticket is worth a dollar only while the coat check is open and honest.
On the XRP Ledger, the ticket is an issued token. The coat check is the issuer. Older XRPL writing calls it a gateway, because money passes through it on the way into and out of the ledger.
The ledger does its part well. It records who holds how many tokens. It moves them in seconds. It shows the issuer's settings to everyone.
It cannot do the other part. The ledger is a computer system. It has no view of a bank account. It cannot make an issuer pay you back. xrpl.org puts it plainly: stablecoins depend on their issuer's integrity. Ask three things about any issuer. Is it reliable? Is it lawful? Is it solvent?
Anyone can issue a token called "USD". The name proves nothing. A stablecoin is a specific issuer's token, identified by that issuer's address.
xrpl.org lists five kinds of currency token by what backs them.
| Type | Backing | Trade-off noted by xrpl.org |
|---|---|---|
| Fiat backed | Government currency, 1:1 | Familiar pricing. Shares the currency's downsides, such as inflation. |
| Crypto backed | Cryptocurrency collateral | Backing wallets can be public. More volatile. |
| Commodity backed | Gold, oil, real estate and similar | Centralized. Needs regular audits. |
| Financial instrument backed | Bonds or equity shares | |
| Non-collateralized | Algorithmic supply control | Typically not considered stablecoins. |
In the strictest definition, only tokens that are 100% fiat backed qualify as stablecoins.
What an issuer does off the ledger
- Takes deposits and issues tokens against them.
- Burns tokens and pays out on withdrawal.
- Tracks its on-ledger obligations against its collateral. xrpl.org's guidance to issuers is to stop deposits and withdrawals if the two do not match.
- Knows its customers before paying out, as most anti-money-laundering rules require.
What sits on the ledger
- The token: a balance on a trust line between holder and issuer, or an MPT.
- The issuer's account settings: freeze and clawback powers, authorized holders, transfer fee.
- The total issued. For trust line tokens,
gateway_balancesreturns it asobligations.
What the ledger does not hold
- The reserves.
- The redemption terms.
- Any audit or attestation.
Those come from the issuer's own publications. Treat them as the issuer's claims, and check who verifies them.
