What we do

Your chat is already the shop. We made it the checkout.

Nigerian sellers close deals in WhatsApp every day, then lose an hour chasing transfer screenshots and typing sales into a notebook that never balances.

Rhodium keeps the conversation exactly where it is and does the awkward half for you: the asking, the confirming, the receipting, and the booking.

  • Each order gets its own account number
  • Transfers confirm themselves in about two seconds
  • Or take USDC on Arbitrum, settled to your bank in naira
  • Receipts go out without you lifting a finger
  • Every sale lands in one naira ledger
What you get

Everything a WhatsApp seller needs to get paid

WhatsApp Checkout

List a product, send a payment request, and let the buyer pay without ever leaving the chat they're already in.

Auto-Confirmed Transfers

Each order gets its own account number. The transfer confirms itself — no screenshot, no “I've sent it, check now”.

Stablecoins on Arbitrum

Take USDC or USDT from any wallet the buyer already has. You choose where it lands: naira in your bank, or USDC in your own wallet.

One Naira Ledger

Both rails land in the same append-only ledger, denominated in kobo. Integers only — never floats, never drift.

Receipts & Restock

The buyer gets a receipt, you get a confirmation, and stock decrements itself. All from one confirmed payment.

Your Numbers, Yours

Sales, orders and running balance for your shop alone — with the whole ledger as CSV whenever your accountant asks.

Why we built it

Built for the seller, not the spreadsheet.

The screenshot problem is not a payments problem, it is a trust problem. A seller cannot tell a real transfer from a doctored one, so she either ships and hopes, or makes a paying customer wait.

So we started at the money and worked backwards. Payments confirm against the rail itself, never against an image. Funds settle to the seller's own account — there is no custody path anywhere in the code to settle anywhere else.

Why choose Rhodium

The money moves before you trust anyone.

Three guarantees that hold whether you take one order a week or a hundred a day.

We never hold your money

Bank transfers settle to your own account. Crypto moves buyer to merchant in a single transaction when you take USDC, or through a licensed off-ramp straight to your bank when you take naira. There is no custody path in the code — every payment rail is required to name you as the settlement target.

A replayed payment can't double-count

Confirmations are idempotent on the provider's event id and the on-chain transaction hash. If a webhook fires twice, or the same transfer is seen by both the webhook and the poller, your ledger still shows one sale.

Books that reconcile themselves

A daily job compares every confirmed payment against the ledger and flags drift before you ever notice it. Export the statement as CSV whenever your accountant asks.

How it works

From chat to confirmed sale, in three steps

Nothing new to learn and nothing to install. You keep selling the way you already sell — bank transfer or stablecoin, Rhodium handles the money and the records.

  1. 01Share the product

    Send your catalogue in WhatsApp the way you already do. Rhodium turns the message into a real order and a checkout link to send back.

  2. 02Buyer pays their way

    One checkout, two rails: a dedicated account number for a bank transfer, or USDC and USDT on Arbitrum, paid from the buyer's own wallet.

  3. 03Everyone gets told

    The payment confirms itself against the bank or the chain — never against a screenshot. You're notified, the buyer gets a receipt to save or share, stock comes down, and the sale is booked in naira.
