Why R-X-ZENITH

Payment infrastructure without taking custody

One reliable payment layer for a hosted page today and a custom API integration tomorrow.

Launch quickly

Verify your wallet, select approved assets, and publish a checkout link without building chain infrastructure.

Direct settlement

The payment asset moves from the customer's wallet to the merchant's verified wallet. R-X-ZENITH does not hold it.

API-first

Create payment intents, verify finality, receive signed webhooks, and reconcile orders with stable identifiers.

One payment rail

From wallet registration to a payment at the till

Links, QR codes, NFC tags, and APIs all open the same payment-intent workflow.

Register the receiving wallet

The merchant enters the Solana address that receives payments; it is checked as a valid address.

Create a payment intent

Set the order, exact amount, USDC or USDT, recipient, and expiration.

The customer signs

The wallet shows the merchant, asset, amount, network, and instructions before approval.

Confirm the payment

Check the arrival in your own wallet. On-chain matching and signed webhooks are not available on this checkout.

Built for developers

One API behind every checkout

Start with hosted checkout, then integrate the same payment-intent contract into POS, commerce, SaaS, or your own product.

Idempotent payment creation
Server-side on-chain verification

Phase 1

Solana, USDC, and USDT first

The first release uses an explicit verified-mint allowlist. Arbitrary token addresses and additional chains remain out of the initial production scope.

Phantom

The customer's own wallet pays the Solana network fee.
The fee is signed and paid from the customer's wallet, so the customer needs a small amount of SOL (about 0.000005 SOL). R-X-ZENITH does not sponsor gas and holds no keys or funds. A merchant-funded fee sponsor is not available on this checkout.

Predictable pricing

0% platform fee on payment volume

Test without a subscription and validate the first 10 finalized live payments. Production membership starts at $9 USD per month; the customer's wallet pays the network fee separately.

FAQ

Common questions

Does R-X-ZENITH charge a percentage of each payment?

No. The working model is a membership fee with 0% platform fee calculated on payment value. Solana network fees still apply.

Who pays the network fee?

The customer does, from their own wallet. R-X-ZENITH is not the fee sponsor and holds no SOL.

Does R-X-ZENITH custody funds or private keys?

No. Customer funds settle directly to the merchant wallet, and R-X-ZENITH must not store or recover customer or merchant private keys.

What does Stripe process?

Stripe processes the merchant's R-X-ZENITH membership subscription only. It is separate from the customer's on-chain payment to the merchant.
