QUSD Community Risk Notice
What to know before you swap QUSD or add liquidity. No jargon, and no figure you cannot check yourself.
An earlier edition of this notice said QUSD pools were “secure and audited”. They are not audited — no auditor has reviewed these contracts. QUSD is backed 1:1, and that is a separate thing from how deep the pools are. This edition gives you the measured numbers.
1. What you should know
Measured- The pools are shallow. $5.33 in total across every QUSD pool. Not “may be low” — that is the number today.
- A $10 trade moves the price by hundreds of percent. The worst of the listed pools moves +718% on $10.
- QUSD is backed 1:1. The backing is carried in the mint record, not in these pools, and a coin is never issued past it. Pool depth and backing are different questions.
- No audit exists. No auditor has reviewed these contracts, so nobody should tell you they are “rated secure”.
2. Check the address, not the ticker
The Addresses- EVM chains. Canonical QUSD is
0xb57bf3c50f20096723b46645f741f632aef220fa, with identical code on BNB Smart Chain, Polygon, Base, Arbitrum and QVTX 42000. - XRP Ledger. The issuer is
rJqjwDAwuSVoppQkrwjJSPzXivspYxZ239. Verify it before you add a trustline. - One live pool quotes the wrong contract. PancakeSwap on chain 56 pairs against
0x63c4664ceb3e93ef22d1e56826395fb1c927c118, which is superseded. Buy there and you receive the deprecated token. This is not a scam clone — it is our own older contract, and it is the thing most likely to catch you out.
3. How to stay safe
Practical- Redeem, don’t sell into a shallow pool. Redemption at par runs through
qusd.quantvestrix.io/redeem. These pools are a listing, not an exit. - On the XRP Ledger, the official books are QUSD/XRP, QUSD/USDC, QUSD/USD and QUSD/RLUSD. On EVM chains, check the contract address of whatever pair you are about to trade.
- If your wallet or explorer shows nothing, that is a known defect on our side: the contract answers TRUE to an ERC-721 interface check, so some explorers file QUSD as an NFT collection. Add the token by contract address and the balance appears.
