Private micropayments on Avalanche

NozKash

Send money. Leave no trace.
The first micropayment protocol where sender and receiver are mathematically impossible to link.

Crypto has no real privacy.
And micropayments don't work.

Every on-chain transaction exposes your entire financial history. And privacy tools that exist today are too expensive to use for small payments.

Your financial history is public
Every wallet address reveals who paid you, who you paid, how much and when — permanently visible to anyone. That's not how cash works.
Existing tools are too expensive
Privacy protocols charge up to 3% per transaction to shield a payment. On a $10 tip, that's $0.30 gone before it moves. Micropayments are completely unviable.
Confidentiality ≠ privacy
Most solutions hide the amount, but the sender's identity stays traceable on-chain. That's confidentiality — not privacy. The link between you and the transaction still exists.
Real use cases blocked
Tipping a creator, paying per article, splitting a coffee on-chain — none of it works privately today. That's a gap in a market processing billions in daily volume.

Three steps.
Zero link between you and the recipient.

Deposit AVAX
Send 0.01 AVAX to the NozKash vault. You receive a cryptographically private token — your key to anonymous funds.
Receive a blind token
Our Mint signs your token without knowing who you are or where it will go. The link between deposit and token is broken at the protocol level.
Redeem at any wallet
Withdraw to a completely different address. No one can connect the origin to the destination. Not a company promise — mathematically impossible.

Simple to use.
Serious cryptography under the hood.

Three technologies working together to give you real privacy at micropayment cost.

BLS Blind Signatures
Privacy that can't be broken
What makes the link disappear
A special type of cryptographic signature where the signer approves something without seeing what they're approving. This breaks the connection between your identity and your transaction — at the math level, not the policy level.
ANALOGY
A notary signs a sealed envelope without reading what's inside. The signature is valid — but the notary never knew the contents.
BN254 Curve + EVM Precompiles
Fast and nearly free
What makes the economics work
BN254 is a special mathematical curve optimized for pairing operations. Ethereum has built-in shortcuts (precompiles) for it — meaning complex cryptographic checks run natively on-chain, extremely fast and at minimal cost. No heavy ZK-proof overhead.
ANALOGY
A calculator with a dedicated button for the hardest math. Press once — the answer appears instantly, for almost nothing.
Stateless Architecture
Your tokens, always recoverable
What makes it resilient
Your private tokens are derived from a seed phrase — just like your crypto wallet. Lose your phone, change devices, start fresh. Your entire balance can be re-derived from one phrase. No server, no backup, no account.
ANALOGY
Your wallet knows your full balance just from your seed — the blockchain is the ledger, your phrase is the key.
MEV Protection built-in
When you redeem, your spend key signs a message binding the funds to a specific destination address. MEV bots can't front-run your transaction — the recipient is cryptographically fixed before the tx hits the mempool.

Real privacy.
Real micropayments. Finally together.
