Questions.

Short answers. The docs have the rest.

What is Pax?

A dashboard that shows the cheapest and busiest hours on Solana for Agent payments (x402) activity. Turns fee data into a simple best-time-to-transact answer.

What works today?

Pax is in development. Every feature is on the status list with what ships next, and the app opens in a sample workspace so you can see how it will work.

Do I need a wallet?

No. You can explore without one. Connecting a Solana wallet only shares your public address so Pax can read your balances; it never asks you to sign a transaction.

Who is it for?

Bot builders and active traders.
