United Stables Claims $1B – I Ran the Contract Audit So You Don’t Have To

CryptoBear

I ran a quick script on Etherscan for United Stables’ deployment. The frontend screams “$1B Total Value Secured.” The contract balance? 200,000 ETH. At $3,000 per ETH, that’s $600M. The remaining $400M is supposedly in USDC and a few long-tail tokens. But their own token, U, is trading at $1.02 on Uniswap V3 – a 2% premium to the peg. That premium alone inflates the “total value” if they count the market cap of minted U as part of the collateral. Classic packaging trick.

Code doesn’t care about your feelings. I’ve been doing this since 2017. I manually audited the 0x Protocol v2 relayer node – found three re-entrancy bugs that the marketing team swore didn’t exist. I’ve seen $1B TVL numbers conjured from thin air before. This is no different.

Context: The Stablecoin Assembly Line

Stablecoins are the backbone of DeFi. We have USDT ($100B+), USDC ($30B+), DAI ($5B+). Every quarter, a new “$1B” project pops up. United Stables claims it reached this milestone by integrating Chainlink data feeds to protect its collateral. Chainlink is the gold standard for oracles – yes. But integration is table stakes, not a moat. Every DeFi protocol with half a brain uses Chainlink. The real question: what is the collateral mix? How is the peg maintained? What happens during a 10% ETH crash?

From my 2020 Uniswap V2 liquidity mining days, I learned that yield is a function of active management, not passive belief. I rebalanced my ETH/DAI pool daily to capture 400% APR. But that was me, not an algorithm with unchecked mint permissions. United Stables’ model appears to be a standard over-collateralized stablecoin: deposit ETH, mint U, pay fees. The twist? They claim their “Total Value” includes the market cap of U itself. That’s like saying a bank’s assets include the money it printed.

Core: On-Chain Verification – The Numbers Don’t Add Up

Let’s get into the code. I pulled the totalSupply() function for the U token. It returns 980 million U. At $1.02 per U, that’s $999.6M – close to the claimed $1B. But this is the supply of U, not the value of collateral backing it. The collateral contract, CollateralManager, holds:

  • 200,000 ETH (~$600M)
  • 150 million USDC ($150M)
  • 50 million DAI ($50M)
  • 200 million in a token called “rETH” (Rocket Pool ETH) valued at $200M using a custom oracle

Total collateral = $1B exactly. But wait – the rETH part. Their custom oracle prices rETH at 1.15 ETH each, but the actual market price on the Rocket Pool staking contract is 1.10 ETH. That’s a 5% overvaluation. On $200M, that’s $10M of phantom collateral. Not catastrophic, but a pattern.

More concerning: the mint function allows anyone to deposit ETH and mint U at a 150% collateral ratio. But the redemption function is rate-limited. You can only burn U for ETH up to 1% of the total U supply per day. If all depositors try to redeem simultaneously, it would take 100 days to drain the ETH. That’s a bank run waiting to happen. I flagged similar slippage issues in my 2022 FTX survival playbook – when I shorted USDT during the depeg, I saw exactly this kind of asymmetry.

I integrated an AI-agent trading bot in 2025 to automatically scan for such vulnerabilities. The bot flagged this redemption cap immediately. Human emotions miss it; automation doesn’t. The bot also checks for oracle dependency chains. United Stables uses Chainlink for ETH/USD and USDC/USD, but uses a custom oracle for rETH. That’s a single point of failure. If that custom oracle gets manipulated (and they have no time-weighted average price), the whole system can be gamed.

Contrarian: Why “$1B” is the Danger Signal, Not the Milestone

Retail sees $1B and thinks “success.” I see the Terra Luna collapse of 2022 – Anchor Protocol had $15B TVL before it imploded. The bigger the TVL, the bigger the target. United Stables’ $1B is concentrated in a few wallets: the top 10 depositors hold 78% of the collateral. That’s a whale cartel. If one whale redeems, the redemption cap kicks in, and the panic spread begins.

During the FTX collapse, I moved $2.5M to cold storage in 48 hours. I learned that counterparties fail when you least expect it. United Stables’ team is anonymous – no track record, no GitHub commits since the initial launch. Their whitepaper cites “algorithmic stability” but doesn’t mention risk scenarios. It’s a marketing document, not a technical specification.

Yield is the bait, rug is the hook. They offer a 12% APR on U deposits. That’s funded by inflation of U itself – not by real yield from lending or fees. The APR is paid in more U, diluting existing holders. This is the exact same mechanism that killed UST. The $1B milestone is the bait they use to lure more liquidity. Once enough is locked, the whale dump begins.

Takeaway: Verify or Die

If you can’t see the $1B on-chain in a way that matches the frontend, it doesn’t exist. I’ve shown you the discrepancy. The U token supply equals the claimed value, but the backing is weak and illiquid. The redemption cap ensures that only the first 1% of depositors get out before the peg slips. Panic sells, liquidity buys. When the next depeg hits – and it will – you want to be on the side buying at $0.90, not holding bags at $1.02.

Code doesn’t care about your feelings. Run your own verification. Pull the contracts. Check the oracle feeds. If you can’t, don’t enter. The market doesn’t reward narratives; it rewards structural understanding.
