Auction X (https://auctionx.si) is the global marketplace for .si domain names, two letters that read as superintelligence, for AI companies and buyers worldwide. Buyers bid at live auctions or buy at a fixed price; sellers list names they own after proving control with a DNS record. Payments are processed by Stripe; transfers are confirmed with the .si registry, Register.si. Operated by ECLIBZ LTD (England and Wales).

## Key facts
- Buyer fees: none. Seller commission: 5% plus a transaction fee covering Stripe's card and payout costs at cost, only when a sale completes. No listing or monthly fees.
- Bidding places a hold on the bidder's card for their maximum; losing bids are released at the close and never charged.
- Proxy bidding with private maximums; a bid in the last 5 minutes extends the auction (soft close). Auctions run 1, 3, 5 days.
- After the sale the seller has 2 days to start the holder change; the registry change is verified automatically, then the buyer has 24 hours to inspect before the seller is paid.
- Open to buyers worldwide. Prices in euros (EUR). Seller payouts to bank accounts in the EU, EEA, UK, Switzerland, the US and Canada.

## Frequently asked questions
### What is Auction X?
Auction X is the global marketplace for .si domain names, the two letters AI and superintelligence companies want. You can buy names at live auctions or at a fixed price, and sell names you own after proving that you control them. Payments go through Stripe, and every transfer is checked against the .si registry (Register.si) before the seller is paid.

### Can anyone buy a .si domain?
Yes. Anyone, anywhere can hold a .si domain, and Auction X is open to buyers and sellers worldwide. Prices are in euros and you pay with a card.

### How does bidding work?
You enter the most you are willing to pay. Your bank holds that amount on your card, nothing is charged. We bid for you one step at a time, only as far as needed to keep you ahead, and your maximum stays private. A bid in the last 5 minutes extends the auction by 5 minutes, so last-second sniping doesn't work. Auctions run for 1, 3, 5 days.

### Am I charged if I don't win?
No. A losing bid is only a hold on your card, and it is released when the auction closes. You pay nothing, and there are no buyer fees.

### When is the winning buyer charged?
Only after the auction, when the .si registry confirms the domain has moved to you, or shortly before the card hold would expire (card holds last about 7 days). The seller's share then waits in the seller's own payout balance at Stripe for a 24-hour inspection window before it is paid out to their bank.

### How do I know the seller really owns the domain?
Before listing, every seller adds a DNS record to their domain that only the owner can create. We confirm it with several independent DNS resolvers and check the domain's holder, registrar and status with the .si registry (RDAP and WHOIS). Live listings are re-checked daily and again in the last hour of an auction; if anything changes, the listing is paused.

### How is a .si domain transferred after the sale?
The seller starts the holder change at their registrar within 2 days. Auction X then checks the registry automatically for the new holder and your private confirmation token. When the transfer is verified, you get 24 hours to check everything, and then the seller is paid.

### What does it cost?
Buyers and bidders pay no fees. Sellers pay a 5% commission plus a transaction fee covering Stripe's card and payout costs, passed on at cost, only when a sale completes. There is no listing fee and no minimum.

### What if the transfer doesn't happen?
If the seller doesn't start the transfer within 2 days, the buyer is refunded automatically. If something is wrong after the transfer, the buyer can report a problem during the inspection window: the seller's payout is stopped until the Auction X team resolves it, and if the domain wasn't delivered as listed the buyer is refunded in full.

### How do I sell my .si domain?
Sign in, enter your domain on the Sell page, and add the DNS record we give you to prove ownership. Set up payouts once (Stripe checks your identity and bank account inside Auction X), then choose an auction or a fixed price. Your listing goes live in minutes with its own cover artwork.

### Which payment methods are accepted, and is my card safe?
Visa, Mastercard and other major cards, processed by Stripe. Card details go directly to Stripe and never reach Auction X. Sellers are paid out by bank transfer to accounts in the EU and EEA, the UK, Switzerland, the US and Canada.

### How do I contact Auction X?
Write to support@auctionx.si. Every email from Auction X comes from that address, and you can reply to any of them.
