Robinhood Chain.
RH402 is the payment platform for USDG on Robinhood Chain. Send to anyone, get paid by address or by name, accept payments as a merchant, and sell with escrow in the market. Connect the wallet you already use. Gas is covered by RH402, and when you want privacy, payments move through a zero-knowledge pool.
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.
Open the explorerPrivate when you want it.
Move USDG into the private pool and pay any username without showing who paid whom or how much. Your phone makes a zero-knowledge proof and the RH402 relayer sends it, so your wallet never touches the payment. Adding funds and withdrawing stay public. Everything in between does not.
- Receipts only you can makeProve you paid a shop at least an amount, without showing your wallet.
- Reviewed deposits, never lockedNew deposits pass a short review before they move privately. A deposit that is not approved goes back to the wallet it came from.
- Track record without a trailSellers prove how many sales they completed, from a fresh wallet.
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.

Open the marketX402: 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.
