What did Circle launch?
Circle, the issuer of the USDC stablecoin, has opened an auction mechanism that connects two sides of the market: those who want to create new USDC (so-called minters) and those who want to redeem USDC back into dollars (so-called redeemers).
According to The Defiant, these are so-called Hourly Match auctions, meaning the matching takes place on an hourly basis. The core of the mechanism: the redemption clearing fee, paid by the party withdrawing money, is transferred to the benefit of the party minting new tokens. CryptoSlate describes it as eligible institutions being able to collect a rebate funded by the matched redeemers.
Glossary of terms:
- Minter (minting): an entity that deposits dollars and has new USDC issued.
- Redeemer (redemption): an entity that returns USDC and wants dollars back.
- Rebate: a return of part of the fee, here to the benefit of the minter.
Who pays and who receives?
The logic of the money flow according to both sources looks like this:
| Party | Role in the auction | Impact on the wallet |
|---|---|---|
| Redeemer | pays the redemption fee | bears the cost, capped at the Express rate |
| Minter | is matched with a redeemer | collects a rebate from that fee |
| Circle | auction operator | sets the cap and the rules |
The key word is "cap". Both CryptoSlate and The Defiant state that the fees charged in the auction are limited to the level of the Express rate, meaning the faster (and more expensive) settlement option Circle offers. In other words, a redeemer should not pay more in the auction than they would pay for an Express redemption.
Why does it matter?
Stablecoins like USDC typically work on the principle of minting and redemption at a 1:1 backing ratio. Shifting the fee from the redeeming party to the minting party is interesting because it creates an incentive to hold liquidity on the minting side. Whoever can act as the counterparty to redemptions can earn income instead of incurring a cost.
This is a mechanism that favors institutional players capable of operating at large volume and in real time. An ordinary retail user generally does not take part in the matching of hourly auctions.
What we still don't know
The sources we have verified describe the principle but do not provide the full numbers. We have no confirmed exact figure for the Express rate, the specific rebate calculation, who exactly qualifies as an "eligible institution", or from when the mechanism has been fully operational. These details should be confirmed only by Circle's primary documentation, which we have not verified at this time.
Nor can we verify the impact on the final redemption prices for ordinary users, because they do not normally use the auction route.
Context: a lawsuit by a Circle shareholder
Separately, and without any link to the auction mechanism, Kryptonovinky.cz and Kryptonovinky.sk (citing Cointelegraph) report that Circle shareholder J. Benjamin Greenberg filed a lawsuit at the federal court in the District of Columbia against President Donald Trump, his family crypto firm World Liberty Financial, affiliated entities, and special envoy for the Middle East Steve Witkoff. According to these sources, Greenberg stated that he owns 10,000 shares of Circle.
This is a separate story concerning the same company. We have no documented causal link between this lawsuit and the launch of the USDC auctions.
What to watch out for with this type of thing
With new stablecoin fee mechanisms, it is useful to watch three things: who exactly is "eligible" (that is, how open the system really is), what the actual fee cap is in numbers, and whether the matching is reflected in minting and redemption volumes in on-chain data. Only then will it become clear whether the mechanism moves real money or is mainly marketing.
