# Can Cardano stablecoins like USDM, DJED and iUSD pay for AI?

> Cardano stablecoins such as USDM, DJED and iUSD cannot be staked, so any yield on them comes from lending them to borrowers, for example through Liqwid, where suppliers receive interest-bearing qTokens. Lending adds smart contract, depeg, liquidity, oracle and bad-debt risk. Gatewayz lists Cardano stablecoins as coming and will add them only through a lending protocol with a published audit.

**In one line:** Stablecoins don't stake; their yield is lending interest, and Gatewayz will only use it through a protocol with a published audit.

On Cardano, you earn yield on stablecoins like USDM, DJED and iUSD by lending them, not by staking them: a [stablecoin](/yield/glossary#stablecoin) does not help secure the network, so the protocol pays it no rewards. Lending protocols such as Liqwid pay suppliers interest from borrowers, and that interest is the only source of a return. Gatewayz lists Cardano stablecoins as coming: they would turn lending interest into an [inference discount](/yield/glossary#inference-discount-balance), but only through a lending protocol with a published audit, with every risk listed on this page first.

**Pre-launch.** The program is built and switched off on mainnet. A working demo runs on Cardano's preprod testnet with test ADA, by invitation. Not available to US or Canadian persons. Every participant must confirm they are not a US or Canadian person before linking a wallet.

## Key takeaways

- USDM is fiat-backed, DJED is overcollateralized by ADA in a smart contract, and iUSD is a synthetic asset minted against overcollateralized loans.
- None of them can be staked. Any return comes from lending or protocol interest.
- On Liqwid, suppliers receive qTokens whose exchange rate rises as borrowers pay interest, and rates rise with utilization.
- Lending adds smart contract, depeg, withdrawal liquidity, oracle and bad-debt risk on top of the stablecoin's own issuer or design risk.
- Gatewayz has not selected a lending protocol. Stablecoins go live only through one with a published audit.

## What are USDM, DJED and iUSD?

They are three Cardano stablecoins with three different designs. USDM relies on an issuer holding dollars, DJED on ADA locked in a contract, and iUSD on loans that over-collateralize every token minted.

- **USDM** is issued by Moneta Digital LLC as a Cardano native token, backed 1:1 by reserves held with US institutions. Moneta's transparency page lists US government money market funds (about 80%) and FDIC-insured USD bank deposits (about 20%). Moneta publishes daily on-chain proof of reserves with a reserve ratio of 100% or more; it names no independent accounting firm.
- **DJED** is issued by COTI on a design from IOG research. A smart contract mints and burns DJED against an ADA reserve, and holders of SHEN, the reserve coin, supply the excess collateral. Per Cardano.org, the reserve is kept between 400% and 800% of DJED's face value. The protocol design is formally verified and peer-reviewed; formal verification of a design is not the same as a code audit.
- **iUSD** is a synthetic USD-pegged iAsset from Indigo Protocol, governed by the Indigo DAO. You mint it by opening an overcollateralized loan (a CDP) in ADA or, in V3, whitelisted Cardano native tokens. Stability pools absorb liquidations, and redemptions support the peg. Indigo's audit page lists reviews by Tweag (2021), MLabs (2022, 2024) and TxPipe (2026, V3).

## How do the three designs compare?

Each design moves the trust somewhere different.

| | Fiat-backed (USDM) | Overcollateralized (DJED) | Synthetic CDP (iUSD) |
| --- | --- | --- | --- |
| What backs it | Dollar reserves held by the issuer | ADA in a smart contract, 400% to 800% of face value | ADA or whitelisted native tokens in loans |
| Who you rely on | The issuer holding reserves and honoring redemptions | The contract and the reserve staying above its floor | Liquidations, stability pools and redemptions |
| Published assurance | Daily on-chain proof of reserves | Formally verified, peer-reviewed design | Reviews listed on Indigo's audit page |
| Main way it can depeg | Doubts about reserves or a run on redemptions | Collateral falling faster than the mechanism responds | Collateral falling faster than liquidations |

## Why can't stablecoins be staked?

Because staking rewards are paid for securing a proof-of-stake network, and only the chain's own coin does that. On Cardano, ADA is [delegated](/yield/glossary#delegation) to [stake pools](/yield/glossary#stake-pool) and rewards come from transaction fees and monetary expansion. A stablecoin held in your wallet takes no part in that, so it earns nothing on its own. That is the main difference from the [ADA program](/yield/assets/ada), where your coins never leave your wallet; [Staking rewards vs an inference discount](/yield/learn/staking-rewards-vs-inference-discount) explains the ADA side.

## How does stablecoin lending work on Cardano?

You supply stablecoins to a pool, borrowers pay interest, and your share grows. On Liqwid Finance, a pooled lending protocol governed by the Liqwid DAO, suppliers deposit into a market and receive qTokens, interest-bearing native tokens whose exchange rate rises as borrowers pay interest. Burning qTokens withdraws the underlying, as long as the market has enough liquidity.

- **Utilization.** Rates rise as more of a market is borrowed. High utilization also means less unborrowed liquidity for withdrawals.
- **Liquidations.** Borrowers post overcollateralized loans, and anyone can liquidate a loan whose health factor falls below 1.
- **Bad debt.** Debt nobody liquidates in time is absorbed by suppliers.
- **Stablecoins as supply only.** Liqwid's docs say stablecoins earn interest only.

Liqwid's security page lists reviews by Vacuumlabs (2023) and MLabs (2025). FluidTokens runs peer-to-peer and multi-pool lending on Cardano, and its audits page lists a Vacuum Labs audit of Loans V3. Gatewayz has not chosen either.

## What are the risks of stablecoin yield?

More than with ADA delegation, because the coins leave your wallet for a contract and are lent out.

| Risk | What can happen |
| --- | --- |
| Smart contract | A bug or exploit in the lending or stablecoin contracts can lose deposits or mint unbacked tokens. Audits lower this risk but do not remove it. |
| Depeg | A stablecoin can drift from $1 through doubts about reserves, a run on redemptions or, for crypto-backed coins, collateral falling faster than liquidations. |
| Withdrawal liquidity | Supplied funds are lent out, so withdrawals depend on unborrowed liquidity. |
| Oracle | A manipulated or stale price feed can cause wrong liquidations or undercollateralized loans. |
| Bad debt | If collateral falls faster than liquidators act, suppliers absorb the shortfall. |
| Issuer | Fiat-backed coins depend on the issuer holding reserves and honoring redemptions. |

The ADA program's risks are on [Risks](/yield/risks).

## What would Gatewayz require before going live?

Three things: a Cardano lending protocol with a published audit, this page updated with that protocol's contract risk, and the same accounting rule as ADA, under which only interest actually received becomes a discount. The discount would stay non-transferable and could not be withdrawn or exchanged. Until then, join the waitlist so we know demand.

## Frequently asked questions

### Can I stake USDM, DJED or iUSD?

No. Stablecoins do not take part in securing Cardano, so they earn no staking rewards. Any return on them comes from lending or protocol interest, which carries smart contract, depeg, liquidity, oracle and bad-debt risk.

### Does an accounting firm check USDM reserves?

Moneta does not name one. It publishes daily on-chain proof of reserves with a reserve ratio of 100% or more, and its transparency page lists US government money market funds and FDIC-insured bank deposits as the reserves.

### What makes DJED different from USDM?

DJED is backed by ADA held in a smart contract rather than by dollars at a bank. Per Cardano.org, its reserve is kept between 400% and 800% of face value, and its design is formally verified and peer-reviewed, which is not the same as a code audit.

### How does Liqwid pay interest on stablecoins?

When you supply to a Liqwid market you receive qTokens, whose exchange rate against the underlying rises as borrowers pay interest. You withdraw by burning them, provided the market has enough unborrowed liquidity.

### Which lending protocol will Gatewayz use?

None has been selected. Gatewayz will add Cardano stablecoins only through a lending protocol with a published audit, and will list that protocol's risks on this page before going live.

### When will stablecoins be supported?

There is no date. Join the waitlist on this page; demand helps decide the order of coming assets on [the assets page](/yield/assets).
