Nava Gateway · verified payments

One endpoint for agent payments, verified before they settle.

Send any payment request through the Nava Gateway. It's checked against the user's policy, and every decision is written to a ledger you can audit.

For payments, x402 & MPP agent builders. Closed alpha.

Not a wallet, not custody. Nava Gateway gates and relays; the funds stay the user's.

The problem

A facilitator confirms the payment cleared. Not that it should have.

x402 and MPP confirm a payment settled, not whether it should have. Self-rolled policy won't carry across rails. Nava Gateway manages spend and risk in one place.

How it works

One surface. Every rail. Checked before it settles.

01

One endpoint

Your agent sends any payment request to a single endpoint; the rail is just a parameter. Phase 1 facilitates and verifies x402 payments on Base (USDC), with more rails coming soon.

02

Verified before settle

The Nava Guardian checks the request against the user's pre-committed policy. Only on approval does Nava Gateway settle on the chosen rail; on reject, it drops or holds it.

03

Written to a ledger

Every request and decision is written to a structured ledger you can audit: one record of how your agents behave with money.

For agent builders

A drop-in facilitator endpoint that adds policy checks to your agent's payments, across venues and rails, without you building them.

For merchants & resource servers

Get paid over x402, with the option that payments arrive pre-verified against the payer's policy. Fewer reversals, cleaner settlement.

What Nava would have blocked

A budget that quietly runs over within the hour, caught before the next charge clears.

SPEND_ALLOWANCE_EXCEEDED. The agent has already run up $108 of inference credits this hour, past the allowance the user set.

Why trust it

An auditable ledger and a deterministic check.

Every request and decision is written to a structured ledger you can audit. Each verdict is deterministic (same payment, same policy, same result) and cites the exact policy field that triggered it. No model sits in the approval path.
