Getting Started

What do I need to buy and sell CryptoMasterpieces?

  • A computer or laptop running the desktop version of Chrome or Firefox
  • MetaMask, a digital wallet used specifically with web apps
  • Ether, a form of digital payment that powers CryptoMasterpieces

How do I install my digital wallet (Metamask)?

To use CryptoMasterpieces, you will need to install MetaMask, a digital wallet. You will need to put money in it to make your first purchase.

Why is Metamask saying my account is locked?

Occasionally, you'll see a lock screen. This happens because MetaMask locks your account after a certain period of time automatically. To unlock simply click on the MetaMask extension and type in your password.

How do I get Ether, the digital currency used to buy and sell CryptoMasterpieces?

For U.S. citizens only: you can buy ether (ETH) in MetaMask. ETH is the digital currency and database that enables our CryptoMasterpieces to be one-of-a-kind.

For everyone else: you will need to purchase ETH from an exchange. The easiest way is using Coinbase and then transferring the ETH from your Coinbase wallet to your MetaMask wallet. Unfortunately, you cannot play CryptoMasterpieces with a Coinbase wallet or any other wallets.

You cannot use USD/CAD to buy a CryptoMasterpiece — currencies need to be converted into ETH first.

How do I send Ether to MetaMask?

For U.S. citizens only: you are able to purchase ETH directly from the MetaMask wallet using the Coinbase widget. This is more convenient and doesn’t require you to create two accounts.

For everyone else: you need to buy ETH from an exchange using normal fiat currency. Coinbase is the easiest to setup however the choice is ultimately up to you. Copy your MetaMask address but clicking on the ‘...’ then ‘Copy Address to clipboard’. Go to Coinbase and click ‘Accounts’ and select your ETH Wallet and then click ‘send’. Paste the MetaMask address in the box with the amount you’d like to transfer.

What is CryptoMasterpieces?

What are CryptoMasterpieces?

CryptoMasterpieces is a platform for buying and selling one-of-a-kind digital masterpieces represented as Smart Contracts. There exists only one Smart Contract for every real world masterpiece. This ensures that only one person can own the "Mona Lisa" CryptoMasterpiece at a time. For 21 days after a masterpiece is created, its price increases every time it is purchased. If someone buys your masterpiece within 21 days of creation, you lose ownership of the masterpiece but receive the price that was paid (up to double). After 21 days, the masterpiece is only purchasable if the owner puts it on sale.

How much does each CryptoMasterpiece cost?

This depends on the masterpiece. Within 21 days of creation, the price of the masterpiece is determined by how many times it was purchased before, as well as if the owner chooses to place it on sale.

Price Range Price Increase Platform Cut
Increase 1 0.001 ETH - 0.02 ETH 100% 5%
Increase 2 0.05 ETH - 0.5 ETH 35% 4%
Increase 3 0.5 ETH - 2.0 ETH 25% 3%
Increase 4 2.0 ETH - 5.0 ETH 20% 3%
Increase 5 5.0 ETH - 15% 2%

After 21 days, the masterpiece can only be auctioned if the owner chooses to auction it.

How does CryptoMasterpiece pricing work exactly?

When each masterpiece is created, it receives what we call a "snatch window" of 21 days. Within those 21 days, anyone can purchase the masterpiece as long as they pay the price calculated in the table in the question above.

21 days after creation, masterpieces can no longer be snatched. They can only be auctioned. Currently, we only support decreasing price auctions. However, we will be adding additional auction mechanisms soon.

Can I decide not to sell my CryptoMasterpiece within 21 days of its creation?

If somebody is willing to pay the new, higher price for your masterpiece, they are able to purchase it without your approval. However, because the purchaser will be paying you for the masterpiece, you will earn a return on your investment. You are then welcome to re-purchase the masterpiece at the new price. After 21 days, the owner of the masterpiece must put the masterpiece on sale for anyone to purchase it.

How do I put my CryptoMasterpiece on sale?

Once you log into your account, access "My Collection" from the "Account" drop-down. You will see a list of all of the contracts that you own. Once you click into a contract, you can set the starting price, ending price, and duration. Sales are conducted in dutch auction style. Auctions begin at the starting price. Then, for the duration that you set in your auction, the price decreases until the ending price is reached. Once the auction reaches the end of its duration, the masterpiece is listed for sale at the ending price until you cancel the auction.

Is this a scam? How are you making money?

We take a percentage of each transaction when a masterpiece is purchased. The contracts are always one-of-a-kind and will forever exist on the Ethereum blockchain.

Is this legal?

All CryptoMasterpieces reference a real world masterpiece in the public domain. In the US, this means any artwork that was copyrighted before January 1, 1923 or any artwork created by an artist who died over 70 years ago. If you believe that an artwork on our platform is currently in violation of copyright, please contact us at
