Question 1

Are Celo Dollar and USDm the same asset?

Accepted Answer

Yes. The same stable asset was formerly named Celo Dollar (cUSD) and is now named Mento Dollar (USDm); this change is a name and brand migration, not a token migration that exchanges an old coin for a new coin. The name took effect after the governance proposal passed. The original contract address, 1:1 U.S. dollar peg target, smart-contract functionality, and reserve operations remain unchanged. Existing DeFi positions, liquidity pools, and integrations are unaffected by this renaming, so users do not need to perform an asset operation because of the name change.

Question 2

What is USDm's price target?

Accepted Answer

USDm targets 1 USDm equal to 1 U.S. dollar; this target describes the protocol peg, rather than meaning that the secondary market will necessarily trade at 1 U.S. dollar at every moment. The protocol maintains this target through reserve backing and fixed-price market-making mechanisms: under normally available conditions, market-making pools provide swaps at oracle prices; during market stress, insufficient liquidity, or triggered security protections, the actual executable price, size, or availability may still differ from the target.

Question 3

How is USDm reserve-backed?

Accepted Answer

USDm is backed by the Mento Reserve; official sources describe this reserve as a diversified portfolio of collateral assets exceeding the outstanding stable asset supply, including stable collateral such as USDC and DAI. The role of overcollateralization is to provide a buffer when demand falls sharply and users collectively seek to exit stable assets, rather than to guarantee the absence of losses or liquidity pressure. The nominal value of reserves is not the only condition. If collateral assets cannot be deployed in time and with low slippage, the stability mechanism can still face pressure; the protocol therefore also manages the impact of large operations on market depth through multiple liquidity venues and trading limits.

Question 4

Will USDm's supply remain fixed?

Accepted Answer

No. USDm is a reserve-backed Mento stable asset; in Mento V3, when a fixed-price market-making pool (FPMM) needs rebalancing, ReserveLiquidityStrategy can mint or burn USDm. Therefore, supply changes are not a preset fixed issuance schedule: USDm is minted when rebalancing requires increasing USDm in the pool, and it is burned when reverse rebalancing requires reducing it. This mechanism shows that supply adjusts with protocol liquidity operations, but it is not equivalent to a prediction of circulating supply or market demand at any particular time.

Question 5

Why might swaps or trading sometimes not be immediately available?

Accepted Answer

Yes, this may happen. Mento's fixed-price pools rely on oracle exchange rates; if a quote is stale, unsafe, or outside the expected range, OracleAdapter validity checks and BreakerBox circuit breakers can prevent the pools from continuing to trade at that price. Even if reserves exist, the protocol will not continue to execute swaps under abnormal quotes, because an incorrect exchange rate could allow traders to extract value at a distorted price. For large operations, time-weighted trading limits also spread operations across multiple blocks or hours to mitigate manipulation and cascading redemption risk.

Question 6

What major risks should be considered when holding USDm?

Accepted Answer

The core risks of holding USDm include peg pressure, reserve liquidity, oracle risk, and smart-contract risk. Under market stress, reserves must not only have sufficient value but also be deployable promptly at an acceptable cost; otherwise, large exits can amplify execution friction. If an oracle is manipulated or data is stale, incorrect prices may affect swaps; smart contracts, upgradeable modules, and governance parameters also carry technical and governance risks. Overcollateralization, multi-source quotes, circuit breakers, limits, multisignatures, and timelocks are buffering measures, not absolute guarantees of price, liquidity, or contract security.
