Gas is on us.

Connect MetaMask, Rabby, OKX, Bitget Wallet or any other wallet. Before every transaction RH402 sends your wallet the gas it costs, whether or not you hold ETH, so a payment costs exactly the USDG you send and nothing more. No new wallet, no seed phrase, no gas token to buy.

Every payment, on the record.

Sender, receiver, amount and memo are indexed the moment a payment lands. Open any payment as a receipt, share it as a card, verify it on chain. Merchants get one-time invoices and QR codes that cannot be paid twice.

A market with escrow built in.

List goods, services or usernames and get paid in USDG. Buyers pay into escrow, not to the seller. The seller is paid when the buyer confirms delivery, or automatically after three days. A report freezes the clock, and RH402 can refund the buyer at any point before release.

One platform, four ways to use it.

Payments

Send USDG to any address or @name from any wallet. RH402 covers the gas, the explorer keeps the receipt.

Market

Sell goods, services and usernames. Buyers pay into escrow and the seller is paid on delivery, with RH402 as the arbiter.

X402: pay-per-request for merchants and machines.

Charge USDG for an API call, a download, a report, a service. Your server states the price, the client pays, RH402 settles the payment and hands you the transaction hash. No keys on your side, no invoicing, no chargebacks.
