How the Auction House Works

1. Creating an Auction

Each artist can create (mint) an NFT directly on the Museum of Contemporary Tattoos Auction House and start an auction using POL or USDC (a stablecoin). A small amount of POL is required to pay blockchain transaction fees. The NFT is created on-chain when the auction starts. All auctions last 24 hours, are public, verifiable on-chain, and open to all collectors.

2. Artist Revenue

90 % of the final sale goes directly to the artist’s wallet. 10 % goes to the museum’s smart contract to support development, hosting, and the AR monument in Lustgarten.

3. Bidding Process

Collectors place bids using connected crypto wallets. The highest bid wins automatically when the 24-hour period expires.

Note: On mobile, please open the auction page directly inside a wallet browser such as Base, MetaMask, or Rainbow. On desktop, connect using a Web3 wallet extension (for example MetaMask) in Chrome or Brave.

4. Transparency

All transactions are fully visible on the Polygon blockchain. The museum never holds or manages artist funds.

5. Ownership

The winning collector automatically receives the NFT in their wallet at the end of the auction.
