QVTX One QONE
Official channels
These are the only official channels. Anything else claiming to be us is not.
| Channel | Where |
|---|---|
| X | x.com/qvtxqusd |
| GitHub | github.com/quant-oss/qone |
| Contract registry | qusdscan.us/contracts |
We will never DM you first, never ask for a seed phrase, and never ask you to send funds to "verify" a wallet. Anyone doing so is not us.
Add to your wallet
MetaMask's own guidance is that a token should be added through the wallet's
wallet_watchAsset request rather than a central registry. These buttons do
exactly that: your wallet asks your permission, and the address comes from this page.

Contract addresses
| Network | Chain ID | Contract |
|---|---|---|
| Ethereum | 1 | 0xba2aAAf685f58156b6420D06FA169B61ED53B945 |
| Polygon | 137 | 0xC88BaD1688bD1725F02f3CF6e5657c1155a4D12c |
| BNB Chain | 56 | 0x4A9463EFf350d90927A45b9Bd39F59eBa24c7969 |
| Base | 8453 | 0x4618091C333819e913de6632Bc26D60503E4bAF6 |
| Arbitrum One | 42161 | 0x3ECcc6E1A19C867E066eD44E4aC539979C1023cf |
Always confirm the address on this page before adding the token to a wallet. A token imported under the wrong address is a different token.
The full estate — all 30 contract deployments across the five public chains, with each one's live verification status — is published at qusdscan.us/contracts.
Verified source
| Network | Sourcify | Verify it yourself |
|---|---|---|
| Ethereum | exact match | creation + runtime |
| Polygon | exact match | creation + runtime |
| BNB Chain | exact match | creation + runtime |
| Base | exact match | creation + runtime |
| Arbitrum One | exact match | creation + runtime |
Exact match means both the creation bytecode and the deployed
runtime bytecode reproduce from the published source — the strongest verification result
available. The build is solc 0.8.24, optimizer enabled at 200 runs,
viaIR, EVM version london.
Token list
Wallets and aggregators that accept a token-list URL can import QONE, QUSD and vQONE across all five chains from:
https://qusdscan.us/qvtx.tokenlist.json
Standard token-list format, 13 entries, served as
application/json. Importing by list rather than by hand is safer: the address
comes from the list, not from a message someone sent you.
Price oracle
QONE's sibling unit QUSD is priced by an on-chain oracle at
0xc234af77d0884ffb31a1a604f212bd5d6c75a4e5, deployed at the same address on
BNB Chain, Polygon, Base and Arbitrum. It exposes the standard Chainlink
AggregatorV3 surface, so any integrator reading a conventional feed can read it
directly. At the last reading it returned 1.00000000 (8 decimals) on all
four chains.
This is QUANTVESTRIX's own oracle. It is third-party readable, not third-party derived, and is published as such.
Supply
Total supply is fixed at 500,000,000,000 QONE with 18 decimals, under an immutable maximum set at deployment. The supply cap is a one-way ratchet: it can only ever be raised toward the immutable maximum, never lowered and never exceeded.
