On September 7, 2026 there were $6,347,386 of ctUSD in existence. That is Citrea's own dollar token, issued by MoonPay on M0 rails and backed by short-term Treasury bills and cash, at contract 0x8D82c4E3c936C7B5724A382a9c5a4E6Eb7aB6d5D. On the same day, five applications running on Citrea published ctUSD balances totalling $7,898,029.

That is $1.55 million of ctUSD more than has ever been minted. Every one of those balances is accurate. The arithmetic breaks because the same coins pass through more than one protocol, and each protocol counts them.

The 627% morning

The thread starts with a number that looked like news. Mystic Finance's lending page went from $4.90 million of deposits to $36.09 million in 24 hours, a jump of 627%. Two chains appeared on its page at once: Flare with $26.17 million and Citrea with $4.64 million. Plume, the chain Mystic actually built on, sat still at $4.93 million.

Read plainly, that is $30.8 million of new money arriving in a day. So look at what the two receiving chains reported. Citrea's chain-wide total went from $7,762,957 on September 6 to $7,718,853 on September 7, which is a decline of $44,104.

Mystic Finance Lending, 24 hours: +$31.2 million. Citrea's chain total over the same 24 hours: −$44,104.

Where the same dollar gets counted

Citrea published the answer itself two months ago. On July 10 it announced that the ctUSD Earn Vault was live, with Upshift providing the vault interface and RockawayX acting as curator. The post says the vault "automatically distributes ctUSD liquidity across premier venues" and names three of them: the ctUSD-USDC pool on Satsuma, the Zentra lending market, and a Morpho lending market reached through the Mystic interface.

Follow one deposit through that. You send 1,000 ctUSD to the Earn Vault. Upshift's page counts 1,000, correctly, because the tokens are sitting in its ERC-4626 vault. RockawayX then lends them into the Morpho market that Mystic fronts. Mystic's page counts 1,000, correctly, because the tokens are now supplied to a market it operates. Two protocol pages now report the deposit, and there is still only one thousand dollars of it.

What the chain page does about it

DefiLlama already knows. Citrea's chain total of $7,712,166 is the sum of exactly six protocols: Morpho Blue at $4,925,980, Zentra Finance at $1,999,545, Satsuma at $781,416, Accountable at $4,671, Juiceswap at $535 and the atomiq bridge at $19. Add those and you land on the chain figure to the dollar. Mystic's $4.64 million is not in there. Neither is Upshift's $2.57 million, nor the $10.23 million sitting in LayerZero's bridge contracts.

The chain page nets out the layers. The protocol pages do not, because a protocol page is meant to answer "how much is supplied to this thing," which is a fair question with a fair answer. The problem is that people read the two numbers as if they belonged to the same accounting system, and headline growth rates come from the one that never nets anything.

Flare tells the same story at ten times the size

Mystic's other new line is bigger and older than it looks. Back in February, Flare launched modular lending markets for XRP built on Morpho, with Mystic serving as the front end and Clearstar and Carpathian curating the first vaults, backed by USDT0, FLR and FXRP. Mystic's $26.17 million on Flare breaks down as $22.05 million of USDT0, $3.37 million of FXRP and $0.75 million of WFLR. Same three assets, same markets, newly given their own page.

Morpho Blue's own Flare entry shows $56.14 million. Mystic's figure is a slice of that, not an addition to it. Flare's chain-wide total moved from $132.87 million to $134.28 million across the day Mystic's $26 million appeared, a rise of about 1.1%. Stack the layers on Flare and the effect gets loud: the 50 protocols with a Flare balance report $449.9 million between them, and the chain page says $134.3 million.

Four checks before you believe a TVL jump

  • Did the chain total move? A protocol adding $26 million to a chain that gained $1.4 million did not receive $26 million of new deposits.
  • Did a new chain appear on the page? Growth that comes from a tracker adding coverage looks identical to growth that comes from depositors.
  • What is the protocol's category? Labels like "Onchain Capital Allocator" and "Risk Curators" describe something sitting on top of a venue, which means its balance is also somebody else's balance.
  • How much of the token exists? Reported holdings that exceed circulating supply are the cleanest proof of layering you will find.

Why a depositor should care

Counting is the boring part. The stack underneath it is not. If you hold ctUSD through the Earn Vault, your money is not in one place. It is spread across a Satsuma AMM pool, the Zentra market, and Morpho markets fronted by Mystic, with RockawayX deciding the split and adjusting it whenever it wants. Citrea's post advertises a 24-hour redemption window, no deposit caps and no lock-up. That window is a promise about the vault, not about the venues below it, and the venues are where the liquidity actually has to be.

The yield arrives the same way. Citrea lists trading fees, borrow interest and ecosystem token incentives as the sources. The first two are earned by the layer at the bottom. The vault collects them, takes its curation, and passes on what is left. Each layer you can name is a smart contract that has to keep working for you to be paid.

The number that should worry Citrea

Citrea's mainnet went live on January 27, 2026 as the first production zero-knowledge rollup settling to Bitcoin, backed by Peter Thiel and Galaxy Digital. On May 5, the project announced more than $50 million of institutional liquidity commitments from Galaxy and other asset managers, alongside a ctUSD pre-deposit vault capped at $15 million with 0.6% of CTR supply set aside for participants. Orkun Kilic, director of the Citrea Foundation, described Bitcoin liquidity across chains as inefficient and isolated in a way that holds back what Bitcoin can do.

Four months after that announcement, $6.35 million of ctUSD is outstanding, and the figure is lower than it was on September 6. That is the number I would put in front of the team, ahead of any TVL chart. A commitment is not a mint. Citrea has built the plumbing that a Bitcoin dollar needs, and roughly one eighth of the announced capital has turned into tokens somebody is holding on the chain.

None of this makes Mystic, Upshift or DefiLlama look bad. Vaults that route into lending markets are a genuinely good design, and a tracker that publishes both a gross figure and a netted one is being more honest than a tracker that publishes only the flattering one. The failure is in the reading. When a lending market's deposits multiply by seven overnight, open the chain page before you open a position, and see whether anyone brought money.
