The problem

Every x402 payment is public by default.

A standard agent payment reveals who you are, which vendor you use, how often you call it, and how much you spend — forever, on-chain.

For a trading desk or research agent, that's not a privacy inconvenience. That's a leak of your actual strategy.

How it works

Three steps. One private balance.

01

Fund your private balance

Deposit USDC once. It's no longer linked to your public operating wallet.

02

Set agent policy

Per-call cap, daily limit, approved vendors, expiry. Your agent can never exceed what you allow.

03

Agent pays, you stay invisible

Your agent settles x402 payments from the private balance. The vendor gets paid. Nobody else sees the relationship.

Principles

Control without custody.

BOUNDED

Agents hold a policy, not a treasury. No seed phrase. No unlimited approval.

PRIVATE BY DEFAULT

Funding and spending are deliberately unlinked — not just a stealth address.

STILL AUDITABLE

Every payment has a receipt. Export what you need for finance or compliance — nothing more.

Honesty block

PRIVATE,
NOT UNTRACEABLE

Deposits and withdrawals are still public. Timing, amounts, and network metadata can still correlate activity. We design for real privacy, not a promise we can't keep.
