Merchant discount infrastructure for Vow commerce

Stablecoin payments. The ultimate rewards programme. This is PriceEdge.

Consumers

Pick your own discount.

At checkout, the shopper decides how much discount to unlock on the purchase. Instead of waiting for a coupon or taking whatever offer is available, the customer actively selects the rate that fits the moment.

Merchants

It costs you nothing.

PriceEdge discounts are funded by the customer, not by cutting into merchant margin. You get the conversion lift and loyalty effect of a better offer without paying for the discount yourself.

And you get payment rails for the future.

Market Opportunity

Meet shoppers where they already pay.

Stablecoins are fast becoming the payment rails of the future. With support from the current U.S. administration and growing regulatory alignment abroad, stablecoin supply is now above $300 billion, and McKinsey and Artemis estimated roughly $390 billion in real payment activity during 2025, more than double 2024 levels.

PriceEdge brings that momentum to merchants in a form shoppers can actually use, bundling stablecoin checkout with a rewards programme built around v$s, the industry standard for rewards.

Stablecoins

Evolving the Checkout

Credit cards come with fraud risk, chargebacks, multiple intermediaries, and settlement delay. Merchants absorb cost and latency even when the shopper experience looks instant.

It's time for an upgrade.

PriceEdge gives merchants a consumer-ready stablecoin payment surface instead of asking them to stitch together wallets, chains, and settlement logic themselves.

Ramp

The Settlement Currency

Crypto-native shoppers want instant, transparent settlement, spending assets like USDT, DAI, PayPal USD, USDC, and TrueUSD.

With us, merchants can accept it all but settle in a single currency: USDR — a stablecoin that saves you credit card fees and burns directly to the bank.

So you get the benefit of broad stablecoin acceptance without needing to manage a crypto treasury or worry about how to off-ramp.

Vow

Discount clarity

Loyalty points, cashback balances, and coupon codes end up as separate silos of value, with confusing rules and unclear utility. Most shoppers do not know what their points are actually worth, or where they can use them.

v$s live in the shopper's wallet, carry a discernible face value, and can be spent across the entire Vow network, instead of being trapped inside one merchant's rewards database. This makes the reward legible, portable, fungible and actually valuable.

How It Works

The store does business as usual. The customer picks the discount.

PriceEdge sits between product price and final payment. The merchant integrates the mechanism, the customer generates his chosen discount, and checkout settles through supported stablecoins instantly and without cost.

01

Stake to unlock v$

Customers deposit VOW and upon purchase receive a rewards in v$s. Vow dollars are an entitlement to claim a reduction in price on their next purchase.

Merchants receiving v$s may simply re-issue them as rewards, as part of a marketing campaign, pay salaries or bonuses with them, use them to travel, or swap them for other assets at a premium on the open market.

02

Customer chooses the discount and currency

Instead of a fixed coupon, customers select how much discount to get on their order, making the merchant instantly competitive, leaving no margin on the table.

And the customer chooses the currency, so there are no barriers to entry. We support all the popular stablecoins (and some more niche choices).

03

Merchant settles in USDR

No matter the customer's choice of payment coin, merchants receive USDR.

As with v$s, merchants may hold these USDR funds in token form, accounting for them as if they were cash in the bank (because they are), or pay employees or vendors.

But Ramp tokens are also directly burnable to the bank, so merchants can treat them as cash.

Discount Engine

Let shoppers choose a purchase-wide discount, with the economics shown clearly.

Use the calculator to change the invoice amount and selected discount, then see how many v$s are unlocked, how much VOW is consumed, what that VOW costs, and the resulting total due on the order.

Why merchants care

  • Turn generic discounts into a loyalty product customers opt into.
  • Let high-intent buyers self-segment without retraining the catalog.
  • Create a reusable discount wallet that moves across campaigns and SKUs.

What shoppers see

“Use v$10 on this purchase” feels clearer than token math. The user sees a straightforward discount line, not a crypto interface.

Superlight Integrations

One button. The PriceEdge experience.

PriceEdge handles the consumer payment flow, wallet onboarding, loyalty enrollment, supported token selection, and the on-chain payment action inside a standard UI (see below) your users learn once. Merchant settles in USDR, a currency that burns directly to the bank.

Whole Integration

Your server first creates an invoice using your PriceEdge API key.

Your checkout page then passes the server-created invoice data to the button as data attributes. The library wires the button, which floats and overlay div, rendering the PriceEdge interface.

checkout.html HTML 
<head>
    <script src="https://priceedge.me/checkout.js"></script>
</head>

<body>
    <button
      id="PriceEdge"
      data-invoice="INV-2048"
      data-amount="29.00"
    ></button>
</body>

The API key stays on your server. For a full sample application, see the Integrations, which include the server-side invoice creation flow and both browser integration options.

Independent Sales Force

Bring merchants into the PriceEdge network and share in the upside.

Anyone can join the PriceEdge independent sales force. If you can source merchants, help them get to launch, and keep them active in the network, you can participate in the rollout.

Merchant-channel partners earn 20% of merchant revenue. In the current operating model, we target merchants purchasing roughly $500 of VOW per week, giving partners a clear economic reason to bring in quality merchants and keep them performing.

PriceEdge gives partners a concrete offer: bring merchants into the network, help them get into production, and participate in the recurring merchant economics rather than a one-time referral bounty.

If you already know e-commerce brands, agencies, PSP integrators, or local merchant operators, this is the quickest way to plug those relationships into the PriceEdge rollout.

Merchant Pilot

Own the discount layer before everyone else does.

PriceEdge is for merchants seeking:

  • to capitalize on the exploding issuance of Vow dollars looking to be spent
  • for an edge where it counts the most: the cost to the customer
  • to capture market share
  • to build a loyalty product that actually locks in customers instead of just racing to the bottom on price

Sign up free of charge, for an initial trial period. After that, PriceEdge takes 2% on processed volume.

Merchants sign up, receive an API key, and integrate the checkout button with their cart. The callback URL is where PriceEdge sends order data after checkout, so merchants can reconcile orders and trigger fulfillment.

Full request and response examples live in the built-in API docs.
