NØNOS Faucet

NOX · Sepolia testnet

Test ETH and NOX.
Nothing to sign.

Test ETH and test NOX on Sepolia. The backend signs a ticket and a relayer submits it; a new wallet holds nothing, so it cannot pay gas to ask for gas.

How it works

quote ·
The contract is asked what this address would get. The amounts on this page are that answer, not a constant. A faucet running low reports the smaller number.
check ·
A human check runs before anything is signed. The cooldown is per address, and addresses are free.
ticket ·
An EIP-712 ticket is signed for that address, those amounts and a nonce. It expires in ten minutes. The key that signs it holds no funds.
relay ·
A second wallet submits the ticket and pays the gas. The tokens go to the address on the ticket.

The cooldown, per-claim caps, daily ceiling and reserve floor are enforced by the contract, not by this server. The signing key is assumed to be stealable; the contract bounds the loss to one day's budget.

Claim

Sepolia only. No signature, no gas, no value.

NOX

This faucet never asks for a signature. Not a transaction, not an approval, not a message. A site asking you to sign is not this one.

What you can do with this today

The pool is not open. The token and the faucet are live. Proofs have been verified against NOX Shield on Sepolia, and the proving system is still under active security work, so there is nothing to deposit into yet. This faucet is how you will get the funds when it opens.

No value. Sepolia is Ethereum's test network. This ETH and this NOX cannot be sold, bridged or converted. Anyone offering to buy test NOX is scamming you.

What works. Hold and transfer test NOX, integrate the ERC-20 in a wallet or an explorer, build tooling against a real V3.1 token, and use the ETH for ordinary Sepolia transactions.

Limits. One claim per address every 24 hours, and a daily ceiling across everyone. Both refill on their own. For a team or an integration, ask and an address can be funded directly.

Verified on Ethereum

A STARK, checked on chain.
Unwrapped.

A STARK verified in Solidity, on a public chain. No SNARK wrapper, no trusted setup, no pairing curve, no L2. Zero-knowledge work on Ethereum is normally wrapped in a SNARK to make verification affordable. This one was not wrapped, and every transaction is public.

Gas, before and after. Bit-identical means the new code returns the same value as the code it replaced.
