Bid on graded cards in live auctions. The winning bid pays the seller and moves the card to you in one step.

How bidding and payment work, and why we never touch your money, is laid out under how it works.
What you can do on Hammerprice
From your first bid to your own sale, and more besides. Every button and link leads to the real page. The small pictures are examples, not live data.
Bid in live rooms
A live room sells its lots one after another on the server clock. The demo rooms are labelled as tutorials.
- Connect your wallet and get a bidder number with one signature.
- Bid with a signed message. Your USDC balance is checked, nothing is locked.
- A bid in the last seconds adds time, so nobody gets sniped.
- Win and pay with one signature: USDC goes to the seller and the card comes to you. We hold nothing in between.
Create a room and sell your card
Sell a graded card from your own wallet. You set the terms and Hammerprice runs the auction.
- Connect your wallet and pick the card from it. Each card shows whether it can be sold.
- Let the AI draft the listing text if you like. You review and edit it before it is used.
- Choose the lot length and an optional minimum price, then go live. You can pause and resume the room.
- You are paid in USDC at the hammer. Hammerprice keeps 2.5 percent of the hammer price from the seller, and that is the only fee we charge.
Offer or open a pack
A pack is a sealed draw from a public pool of real cards. A seller builds it from cards in their own wallet, the buyer pays the seller directly, and a draw that anyone can recheck picks the card.
- A seller with a signed-in wallet picks real cards from that wallet. Availability can be limited to approved sellers.
- The seller sorts the cards into 1 to 8 tiers, sets the odds per tier in percent (they must add up to 100) and the price in USDC, then publishes.
- The odds, the whole card pool and a commitment hash are public before the first sale. After publishing, none of it can be changed.
- A buyer (18 or older) pays the seller directly with one signature. Only when that payment is final does the verifiable random draw (ECVRF) pick the card.
- The seller delivers the drawn card from their own wallet to the buyer within the deadline. Every draw has a public proof page and every seller a public delivery record.
Chat in the room
Every room has a pre-moderated chat, so the talk stays about the cards.
- Signed-in bidders can write. Everyone else can read the approved messages.
- Your message waits for approval. Until then only you see it.
- The room owner gets a popup with a preview and approves or rejects it.
- The public chat shows a bidder number or a display name, never a wallet address.
Buy and bid from Telegram
Connect the bot @hammerpricebot and follow a room from your phone. Alerts are opt-in.
- Connect Telegram in your profile with one tap on Start.
- Get an alert when you are outbid and when you win.
- Send /watch 3, /watch 5, /watch 10 or /watch all to hear when the next lots of a live room open.
- Tap the Bid button under an alert: the room opens with the amount filled in and you confirm in your wallet. The bot never bids for you.
Ask the AI agent
Talk to the agent in German or English. It only makes proposals, you decide.
- Search open and upcoming lots in your own words.
- Have it prepare a bid proposal, or draft a listing for a card you want to sell.
- A signed-in wallet is required. You confirm every step yourself, and the agent never bids or pays.
Your profile and wallet
One page for everything that is yours.
- Choose a username and a picture.
- See your USDC and SOL balance and the cards in your wallet.
- Follow your bids, wins and payments, and your sales with their prices.
- Choose which Telegram alerts you get.

Need a wallet?
To bid you need a Solana wallet in your browser. It is free and takes two minutes.
On a phone, open this site inside your wallet app's own browser. A normal phone browser cannot reach your wallet app.
