PRXVTVerifiably private.
Not just promised.
Privacy preserving access to leading models
An LLM gateway that can't link your wallet to your conversations. No KYC, no account. ZK-gated, anchored on Base.
§01 / six things you don't give up
Most AI bills privacy as a setting.
We make the lack of it impossible.
No payment linkability.
Your USDC deposit funds an anonymous on-chain commitment, not an account. The wallet that paid and the credential that asks are mathematically impossible to link.
No prompt linkability.
Every message is gated by a fresh zero-knowledge proof spending a one-shot nullifier. The server cannot tell which prompts came from the same user.
No IP linkability.
Optional Nym mixnet transport routes traffic through three randomly selected mix hops. Our server sees a gateway IP. Never yours.
No data retention.
No prompts logged, no responses retained server-side. Your conversation lives in your browser and nowhere else.
No cloud history.
Conversations are encrypted in your browser's local storage under a key derived from your sovereign secret. One click in Settings wipes everything.
No wallet linkability.
Your wallet signs the deposit transaction and nothing else. The chat side never touches your wallet. Your credential file stands in for it from that moment forward.
§02 / how it works
Deposit USDC once.
The server signs every reply but never learns who you are.
Your browser builds a Noir UltraHonk proof for each turn. The proof spends one ticket from an anonymous deposit. The server can verify and bill, but the wallet that funded the deposit and the one asking the model are cryptographically impossible to link.
