Gasless USDG payments on 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.
Gas is on us.
Connect MetaMask, Rabby, OKX or any other wallet. Whenever it runs low on ETH, RH402 tops it up before you sign, 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 explorerA 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.
- Transactions
- Request exact amounts with one-time invoices and QR codes. Each invoice can be paid once, by anyone, from any wallet.
- Merchants
- Accept USDG at checkout with a pay link or QR, or charge per request through X402. Settlement is on chain within seconds.
- 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.
