Fraud protection

Risk scores on every bidder

How it works

Your first Shopify auction is three steps away

1

Install and pick what you sell

A four-step setup asks what you sell, which features to turn on, and where emails go.

2

Add the blocks to your theme

Rarity is a theme app extension, so you add the auction, offer and drop blocks from the theme editor without touching code or theme files.

3

Launch your first rare product

Pick a product, set the rules and go live, with checkout staying on Shopify so payments, taxes and shipping work exactly as they do today.

Questions

Frequently asked questions

Do bidders need a customer account?

No. A bidder enters an email, verifies it once with a one-time link, and can bid or make offers from then on, and if they're logged into your store Rarity uses that account automatically.

How do winners pay?

Rarity creates a Shopify draft order for the winning bid or accepted offer and emails the checkout link. Payment, taxes, shipping and fulfilment all stay in Shopify.

Will it slow down my storefront?

The blocks load only on pages that use them and only when a listing is live. Everything else on the page loads as usual.

Does it change my theme?

No. Rarity is a theme app extension. You add its blocks in the theme editor and remove them the same way. Nothing is written into your theme files.

What happens to my data if I uninstall?

All of your store's data, including bidders and launch-list subscribers, is deleted when Shopify sends the uninstall notice. See the privacy policy for details.

Can I run print drops and limited editions without an auction?

Yes. A limited drop can be a plain timed release with a countdown, a launch list and edition badges, and auctions are only there if you want them. Anything unsold after a drop can be moved to a Shopify auction in one click.

Can I stop a shill bidder?

Yes. Every bidder gets a risk score from verification, bid patterns and rate limits. You can block anyone from the Collectors page, and blocked bidders can't bid or offer on anything.
