Each auction has a specified start date and duration. You can see it in the auction detail when you hit the “Place bid” button.How to place a bid

Minimum bid is 1 CLO.
Your bid must be higher than the previous bid by more than 5% of the previous bid. The minimum is calculated and visible under the input box.

Important! The amount you bid is the amount you pay for the NFT. You cannot cancel your bid. No one can cancel it since the logic is completely on-chain. So be very careful how much you want to pay for the NFT. When someone outbid you, your money will be sent back to your wallet almost immediately (in block transaction). When the auction ends your NFT is not automatically minted. The contract waits for someone who runs the endRound function. When this function is called your NFT is minted to your address. We have an automatic job which executes this function once per day. So you can wait or you can run the function by yourself.

You can use the “Claim” button on the “My bids” page. When the NFT is not minted you can see the button. When the NFT is minted the button is not visible and you can find your NFT on the My NFT page.

The solution is completely “on-chain”. It means that you can run all the functions directly in the contract (using explorer or remix). You can place a bid or buy an NFT. You can also read all the important information such as edition description, artwork description, and many more.

You can see and download your NFTs on the “My NFTs” page here. Your NFTs are in your wallet, you can see the ART token if you search your address in explorer.callisto.network. At this moment Callisto team is working on implementation of NFTs directly to the explorer. The NFTs should be also visible in CryptoBot applications.
Yes, you can use a “transfer” button on the “My NFT” page. When you send the NFT, please make sure you are connected to the Callisto Network, otherwise the NFT will not show up in the new wallet. Because of security features built into the new CallisoNFT Standard, you cannot accidentally lose your NFT by sending it to the wrong wallet address, which is a risk with other NFT standards.

No. Each NFT is minted when you purchase the NFT.
When you buy an NFT, the NFT is minted with a serial number which follows the previous one. The serial numbers start from #1.
Yes. Our model is different from the usual NFT collections that are based on each piece of art having different characteristics. Our NFTs function much more like limited edition lithographs. Please have a look at the “About” section where this is described.
You need a Metamask wallet and enough Callisto coin (CLO) to cover the minting cost. Everything is described in How to buy CLO and How to buy NFT.
We prefer quality over quantity. We are looking for experienced, high-quality artists. Our aim is not to release simple photos of artwork they've already created. We are looking to create NFTs that in some way add value to an artists' body of work.
