Nyxora · $NYX

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.

NYX is public and tradeable; wrap it into cNYX the moment you want your balance to go dark. Two tokens, one protocol.

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.

On-chain, your balance looks like 0x02a2e37a…aa36a70500— an opaque handle. Only your key turns it into a number. That's the whole idea.

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.
Supply: 1,000,000,000 NYX. The cap is enforced in the token's transfer logic; the pool, router, and treasury are exempt so liquidity and the tax always work.

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:

Vault
Shield assets into encrypted balances and back. The pool total is public; your share is encrypted.
Swap
Trade with a hidden size against an oracle price — the amount you move stays confidential.
Stealth payments
Pay someone at a fresh one-time address with no public link to them (EIP-5564).
Governance
Cast votes whose weight and direction are encrypted until the tally.
Auction
Sealed-bid auctions — bids are encrypted, only the outcome is revealed.
Mining
Earn emissions for providing privacy / liquidity to the confidential pools.
Disclose
Selectively reveal a balance to a specific viewer with a view key — proof without doxxing.

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.
If your goal is unlinkable, no-trace movement of transparent ETH, confidentiality alone won't do it — that needs an anonymity set (a crowd) or a privacy coin. Nyxora hides how much and, with stealth addresses, who receives — not the existence of the transaction itself.

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.

NYX is a fixed-supply ERC-20 with no transfer tax. The 1% buy/sell tax lives in the Uniswap V4 pool hook as a hard-coded constant — there is no switch to crank it up or freeze trading.

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.
