A SmartSite is a profile page hosted at your own swop.id handle — travis.swop.id, for example. Rather than one flat column of links, it is organised into tabs you name and order yourself, and each tab holds whatever you drop into it: social links, a blog, audio and video, portfolio and position widgets, or products for sale. The difference that matters is the last one. A link-in-bio page points at a checkout somewhere else; a SmartSite takes the payment itself, and the money settles into a wallet whose keys never leave your device.
What a SmartSite is
Think of it as the page a wallet grows when it also has to be a public identity. It lives inside the Swop app rather than on separate hosting, so the same account that holds your funds also owns the page — no CMS, no separate login, no plugin to connect a payment processor. Swop is fully self-custodial — keys are generated and held on your device; Swop never holds them — which is what makes "the page takes the money" a meaningfully different statement from the same sentence on a hosted store.
Tabs, not a list of links
The organising unit is the tab. You create them, name them, and set their order, and each one holds a sequence of blocks. In practice that means a SmartSite can carry several different jobs at once without any of them crowding the others out:
- Profile and links. The social block set — the conventional link-in-bio job, and the reason most people arrive.
- Writing. Blog posts published straight to a tab, so long-form lives on the same handle as everything else.
- Media. Audio and video blocks for people whose work is not text.
- Wallet surfaces. Portfolio, positions and token widgets — the same data the app shows you, exposed publicly if you want it.
- Products. Items for sale, which is where the page stops being a directory.
None of these are separate products with separate accounts. They are blocks on tabs on one page.
The part that settles money
Adding a product to a SmartSite does two things. The obvious one is that a human visitor can buy it. The less obvious one is automatic: every SmartSite is an x402 storefront — any product a user adds is automatically payable by AI agents in USDC over the x402 protocol, with payout going directly on-chain to the seller. There is no separate setup, no merchant application, and no verification step to switch it on.
That matters more than it sounds like. The next wave of buyers is not only people scrolling a feed; it is software running errands on someone's behalf, and software cannot fill in a checkout form. A page that speaks a payment protocol can be bought from by an agent that discovers it mid-task. We wrote up the mechanics separately in what is x402 and the storefront angle in a storefront AI agents can buy from.
Gated sections
Tabs carry an optional gate, which means a section can be restricted rather than public. The useful shape here is a page that is mostly open — profile, writing, shop — with one tab reserved for people who hold something. It saves running a public page and a members' area as two disconnected things, and it keeps the gate attached to the wallet rather than to an email list.
What it doesn't replace
A SmartSite is not a website builder. You are arranging defined blocks inside tabs, not writing arbitrary layout, and if you need a marketing site with bespoke design and its own information architecture, you still need one. It is also not a substitute for a storefront with deep catalogue management — the product blocks are for a handful of things you actually sell, not a thousand SKUs.
What it is good at is collapsing the usual stack. The profile, the links, the writing, the shop and the wallet are normally five services that all point at each other. Here they are tabs. Swop runs on Solana, Ethereum, Base, and Polygon, on iOS, Android, and the web app at swopme.app.
FAQ
What is a SmartSite?
A profile page at your own swop.id handle, organised into tabs you name and order. Each tab holds social links, a blog, media, wallet widgets or products. Because it lives inside a self-custodial wallet, it can take payment directly instead of linking out to a checkout elsewhere.
How is a SmartSite different from a link-in-bio page?
A link-in-bio page is a directory — every tile sends the visitor somewhere else to do anything. A SmartSite is the destination: a product on the page is paid for on the page, and the money settles to the owner's self-custodial wallet.
Can AI agents buy from a SmartSite?
Yes. Every SmartSite is an x402 storefront: any product a user adds is automatically payable by AI agents in USDC over the x402 protocol, with payout going directly on-chain to the seller.
Can I restrict part of my SmartSite to certain holders?
Tabs carry an optional gate, so a section can be restricted rather than public — member-only material alongside a public profile, without running two pages.
Do I need a separate website?
It depends what you need. A SmartSite covers profile, links, posts and selling on one handle. It does not replace a full marketing site with custom design and arbitrary structure.
