Three things to know

Swop Pay, in three lines.

One link, every buyer.

People pay by card or crypto on a simple Buy page. AI agents pay the same link on their own, in USDC.

Live since Sep 2026 for agents

Simple, visible fees.

0.5% when a person pays (minimum $0.015), taken from your side so buyers pay your price. AI-agent purchases: 0% at launch.

The fee comes out of your side, not the buyer's

Paid in USDC, to you.

Money lands in the wallet behind your swop.id. Crypto works for everyone; card needs a one-time business verification.

Swop Pay, in plain words.

If you can share a link, you can sell. Here’s the whole idea on one screen.

What it is
A checkout that lives inside a link. You make a product once, and anyone who opens the link can pay for it.
Who it’s for
Creators, shops, freelancers, pop-ups: anyone with something to sell, online or across a counter.
What it costs
0.5% when a person pays (minimum $0.015), taken from your side so the buyer pays your exact price. 0% platform fee when an AI agent buys, at launch.
What you get
USDC, a digital dollar, in the wallet behind your swop.id. It settles in seconds, so it’s actually yours, not “pending”.
What you need
The Swop app and a swop.id. Card payments need a quick seller verification; crypto and AI agent payments don’t.

More than checkout

Send it anywhere. Launch your own. Put it on your site.

Swop Pay is the money side of your swop.id: the same wallet that gets paid can send, launch products and tokens, and plug into the website you already have.

Send money anywhere.

Pay any swop.id or wallet address with any token you hold: USDC, ETH, SOL, POL or the rest of your wallet.

  • Solana, Ethereum, Base, Polygon and Arbitrum
  • Type a name, not a 42-character address
  • Swap first if they want a different token

  • Geo Bucks: your own store credit, $1 each, burned when spent

Sell what you made right where your customers already are, three ways, no new platform:

  • A link or button to your Swop checkout
  • Embedded checkout on your pages
  • The API to create checkouts from your server, with signed webhooks when you're paid

S.04 · How it works

From product to paid.

One link, four moments: you make it, a person pays, an AI agent pays, and the money lands with you.

01 · Create

One product. One link.

Add a photo, a price and stock in the app, or just tell Ovi. The link works on your SmartSite, in your bio, on a QR code or an NFC card.

02 · People pay

A Buy page people trust.

Buyers pay the list price by card or with any supported token. Passkey or email, and the network fee is covered.

03 · Agents pay

AI agents buy too.

When an AI assistant shops for someone, it pays the same link automatically in USDC. No account, no form, nothing for you to set up.

04 · You get paid

USDC, in seconds.

A person’s payment arrives minus 0.5%; an AI agent’s arrives in full at launch. Every sale gets a receipt, and your website can be told automatically through a webhook.

S.05 · Fees

Simple fees. Do the math.

When a person pays, the fee is 0.5% (minimum $0.015) and comes out of your side, so the buyer always pays exactly the price they see. When an AI agent buys, there’s no platform fee at launch.

No paperwork to take crypto

Crypto and AI agent payments need no identity check: list a product and agents can buy it the same minute. Card payments need a quick seller verification first, and pay out through the card rail, so an order is never paid twice.

For developers

Every product is an x402 endpoint.

Non-browser requests get an HTTP 402 challenge, pay USDC on Base, and receive the order. Swop speaks x402 v1 and v2, settles through Coinbase's facilitator and lists stores for discovery. Agents can also buy through the Swop MCP.

S.10 · Questions

Asked and answered.

How much does Swop Pay cost?

When a person pays by card or crypto: 0.5% of the sale, with a minimum of $0.015. You absorb it, so buyers pay exactly the list price. When an AI agent buys, there’s no platform fee at launch: you receive the full price in USDC.

What is USDC?

A digital dollar. Each USDC is designed to be worth $1 and is issued by Circle. It arrives in seconds and settles straight into your wallet, which means it’s final rather than “pending” for days.

How do AI agents buy from me?

When an AI assistant or shopping agent opens your product link, it can pay automatically in USDC on Base and get the order back, with no account or checkout form. You don't need to set anything up: if you have a product, agents can buy it.

Do I need to verify my identity?

Not to take crypto or AI agent payments. Card payments need a quick seller verification first.

What do I get paid in?

Crypto and agent payments land as USDC in the wallet behind your swop.id. Card payments pay out through the card rail once you're verified.

What about physical products?

For things you ship, the payment is held in escrow until delivery and then released to you. Digital items deliver instantly.

Can I use it on my own website?

Yes. Take checkout on your own site, embed products, and receive signed webhooks (automatic messages to your server) for each order. The developer quickstart walks through it.
