Money the chain
computes on but
can't read.
Nyxora is a confidential-finance protocol on the EVM. Balances and amounts live on-chain as encrypted ciphertext — the network verifies and computes on them without ever seeing the numbers. Only your key turns a balance back into a value.
Introduction
On a normal chain, every balance and transfer is public forever. Nyxora keeps the same open, verifiable settlement — but the amountsare encrypted end-to-end using fully homomorphic encryption (FHE). The chain stores an opaque handle; the protocol does math on the ciphertext; only the holder's key decrypts the result.
There are two faces to the token: NYX, the public, tradeable ERC-20, and cNYX, its confidential wrapper. Hold NYX like any coin, or wrap it into cNYX to make your balance unreadable on-chain.
How confidentiality works
Nyxora is built on Zama's fhEVM. An encrypted balance is an euint— an integer that's been encrypted under a network key. Transfers, swaps, and votes are computed directly on these ciphertexts, so the protocol can enforce “you have enough to spend” without anyone learning how much you hold.
When you want to see your own balance, your wallet does a user-side decryption: the ciphertext handle is re-encrypted to your key and decrypted locally. The plaintext never touches the chain.
The $NYX token
NYX is a plain, fixed-supply ERC-20 — deliberately clean so it integrates with every wallet, router, and aggregator. It carries no transfer tax. Two launch protections live on top:
- 1% buy / 1% sell tax, paid in ETH. The tax lives in the Uniswap V4 pool hook, not the token. Every swap is skimmed 1% on the ETH side — buys pay 1% of the ETH in, sells pay 1% of the ETH out. You are never taxed in NYX, and the rate is a hard-coded constant that can never be cranked up.
- 2% max-wallet at launch. An anti-whale / anti-bot cap: no single non-exempt wallet can hold more than 2% of supply. It can be lifted once, permanently, by the owner — and never re-imposed.
cNYX — private balances
Wrap NYX → cNYX and your balance becomes a confidential, ERC-7984 token: the amount you hold is encrypted, and so is every transfer. Unwrap cNYX → NYX any time to go back to the public coin. The wrapper is a vault that holds the real NYX 1:1 and mints you an encrypted claim on it.
The same machinery wraps other assets too — shield USDC into cUSDC, hold an encrypted balance, transfer privately, and unwrap when you want it public again.
The protocol
Everything on Nyxora is built on the same encrypted-amount primitive:
Stealth payments
Stealth addresses (EIP-5564) let someone pay you without revealing who got paid. You publish a meta-address once; senders derive a brand-new one-time address from it for each payment. Only your viewing key can detect those payments, and only your spending key can move them. No crowd or mixer required — it hides the recipient at volume one.
The sender posts a small public hint (an ephemeral key + view tag) so you can scan and find payments meant for you. Everyone else just sees a transfer to an address that looks like noise.
Privacy model & limits
Being honest about the threat model matters more than marketing it. Here's the truth:
- Hidden: your balances, transfer amounts, swap sizes, bid sizes, and vote weights — encrypted on-chain, readable only by you.
- Hidden recipient: stealth payments break the on-chain link to who received funds.
- Still public: that a transaction happened, who submitted it, gas, and timing. Confidentiality hides amounts and balances — it is not a mixer and does not break the sender↔transaction link for transparent value.
Contracts
Contract addresses are published here at launch. Everything is verifiable on Etherscan — read the source, the fixed supply, and the 1% tax for yourself before you ever send funds.
Security & disclaimers
The contracts are self-reviewed with a full test suite, and an independent audit is on the roadmap. As with any onchain protocol, verify the deployed code, the fixed supply, and the tax constant yourself before sending funds.
Nothing on this site is financial advice. Confidentiality protects your amounts and balances; it is not anonymity, and it is not a substitute for your own operational security. Use at your own risk, with funds you can afford to lose.
