Pay anyone, privately.

See it work, on mainnet.

Real transactions on NEAR mainnet; the demo-wallet scenes are on testnet and labelled. Long on-chain waits are sped up and marked.
What you can do

Private, by proof. Not by promise.

Private sends

No relayer. No server.

Your browser makes a zero-knowledge proof in about seven seconds, and the NEAR contract verifies it. Sender, recipient and amount stay hidden. Even the person you pay can't tell who sent it.

Private swaps on Rhea

Real liquidity, hidden trader.

A single-use account, paid through the open ring, swaps on Rhea and deposits the result back as a private note. The swap is public; who made it isn't.

USDCUSDTRHEAZECAURORA
Peer-to-peer swaps

Both sides, one transaction.

Trade directly with someone by offer code. Both legs settle atomically, with both tokens and both amounts hidden.

Private AI agents

Private inference. Private payments.

Give an AI agent its own private wallet. Its model runs in a TEE on NEAR AI Cloud, and we check the Intel TDX attestation ourselves. Spending limits live in code, not in the model.

Why NEAR

Anonymous. No relayer.

On Solana

An anonymous transaction needs a relayer. A fee payer's key can spend its whole balance, so it can't be shared. The relayer has to be online, and can refuse you.

On NEAR

A key can be limited to one method on one contract. So we publish it: anyone signs, nobody can move funds, and no relayer is needed.

Check it yourself

Live on mainnet. Every claim links to the chain.

Status

Honest about its limits.

Unaudited

Reviewed by AI agents, not yet by an auditor. Read the security notes before you deposit.

Single-party setup

The proving key's trusted setup had one contributor. A multi-party ceremony is on the roadmap.

Capped deposits

About 50 NEAR worth per token while it's young. The contract is upgradeable for bug fixes.
