To trade and hold Cryptographs, you need a digital wallet. A digital wallet acts like a bank account on the blockchain.

You can create a secure non-custodial blockchain wallet in seconds on our website with Torus by signing in with Google, Facebook, Apple, Twitter, Reddit, Twitch, and Discord. If you have already created a Torus wallet, make sure you use the same one-click login method each time you log in. Create a Torus wallet

Every wallet on the Ethereum blockchain has a public address (e.g. 0xaba935f589805095a892ecefdb6eb83eff45d67), which is in essence the account number of your digital wallet. People who know your wallet address can send you money (ETH), gift you Cryptographs and also see what is in your wallet.

Cryptographs are only bought and sold using ETH, the currency of the Ethereum blockchain. This ensures all Cryptograph data, ownership records and transactions are processed securely and in a decentralised way by our audited smart contract.

You can buy up to $100,000 worth of ETH in a few day with many traditional currencies using the Torus wallet onramp providers. Get ETH with Torus

If you wish to buy a larger amount of ETH in a single day, we can also recommend using an over-the-counter (OTC) desk such as Kraken OTC or Genesis Global Trading.

If you already own cryptocurrencies other than ETH (e.g. Bitcoin), you can exchange them for ETH on exchanges such as Binance or Changelly.

To sell your ETH for traditional currencies (e.g. USD, EUR, GBP...) you can use exchanges such as Coinbase, Kraken, Gemini or Bity.

We require users to verify their identity in order to place bids worth over €10,000. Verify Your Identity

Although not strictly required by law, we carry out these identity verifications because most charitable organisations will not accept donations over a certain amount if the source of funds cannot be verified. To perform these checks, we use the trusted UK-based digital identity platform Yoti.

Yes, Cryptograph works the same way on all mobile devices. If using Torus, you can log in easily using any recent web browser with cookies enabled.
We recommend the following web browsers: Chrome, Firefox, Brave, or Safari. If using MetaMask, we recommend using their MetaMask iOS or Android app.

New Cryptographs are published and sold at auction on the Cryptograph platform, after which they can be traded between collectors via secondary market auctions.
Buying a Cryptograph at its initial auction
Cryptographs are initially sold in a 72-hour long GBM auction. Bids must be fully-funded. If a bid is placed less than 10mins before the scheduled end of an auction, the countdown will be reset to 10mins. The winner of a Cryptograph auction receives the collectible in his or her collection automatically at the end of the auction (this automatic transfer can sometimes take a few minutes).

Making an offer on a Cryptograph on the secondary market
If a Cryptograph is not currently under auction, you can make an offer to the owner. Offers must be fully-funded. The owner of a Cryptograph can set an Auction Trigger: If you make an offer equal to or higher than this amount, a 36-hour auction will automatically start with you as the highest bidder. If you are still the highest bidder at the end of the auction, you will become the new owner. The owner can also start an auction at any time.

To place a bid (or send any transaction to the Ethereum blockchain), every user must pay a gas fee. This gas fee is taken directly by the blockchain to process the transaction and does not go to us.
The gas fee to place a bid on a Cryptograph fluctuates. You can find the latest gas prices at the Ethereum Gas Station. The gas fee to place a bid is currently around 0.0025 ETH (~$0.50) and it is automatically calculated and prefilled so you only have to confirm the transaction before submitting it.

Cryptographs are sold using an innovative auction model called a GBM auction. A GBM auction is similar to a traditional English auction, with one notable difference. If you are outbid, you will receive between 1% and 10% more than you put in, depending on how large your bid was compared to the previous bid. The extra 1%-10% the bidder received when outbid is called an incentive.

The GBM auction model is also applied in the secondary market i.e if your offer to a Cryptograph collector is outbid by a higher offer, you will also receive an incentive. This means that everyone placing a bid or an offer on a Cryptograph can either win a Cryptograph or make a return.

Yes, you can place bids on as many Cryptographs as you want. However, each bid has to be fully-funded which means that amount is locked and cannot be used for other bids until it is unlocked by you being outbid or if you cancel an offer on the secondary market.

You can only cancel an offer made on a Cryptograph that is not currently on auction.
If your offer is the first one or it has been outbid by a higher offer, you can withdraw your offer for free. However, if you are the highest bidder and you were not the first to make an offer, you will have to pay a cancellation fee.

Collectors can always make offers for your Cryptograph, it is then up to you to decide if you would like to accept the current highest offer or not. If you accept the standing offer, a 36-hour long auction will start automatically with this offer as the starting bid, and you will sell your Cryptograph to the highest bidder at the end of the auction.
You can also set a (public) auction trigger that, if met by an offer, will automatically start an auction with this offer as a starting price to sell your Cryptograph.

There is a fee equal to 10% of the money exchanged (winning bid minus distributed incentives) at the point of transactions i.e. you as the seller will receive 90% of the proceeds.

You can gift a Cryptograph to any public address for a transfer fee equal to 15% of the last sale price. Simply follow the steps after clicking “Gift” on the page of the Cryptograph you wish to give.
You will need to input the wallet address of the lucky person. If you want to gift a Cryptograph to someone who does not have a blockchain wallet, invite them to create a Torus wallet and to let you know their wallet address (which they can find in My Profile).

NB: If gifting to a custodian wallet or marketplace that does not support the ERC-2665 standard, you may want to additionally pre-pay the next transfer fee.

Yes, Cryptographs are ERC-721 tokens, hence they can be transferred to other marketplaces. Just like gifting, a transfer fee equal to 15% of the last sale price must be paid to transfer a Cryptograph to be sold on another marketplace (e.g. Opensea).

NB: If transferring to a custodian wallet or marketplace that does not support the ERC-2665 standard, you may want to additionally pre-pay the next transfer fee.

No, there are no accounts on the Cryptograph website, and Torus only uses the account you chose to sign up with (e.g. Google, Discord...) as a unique verifier to create and access your wallet. Torus does not record account data nor track users beyond the initial login.

The provider of the account you use to sign up with (e.g. Google, Discord...) will not know your wallet address and will have no way to track what you are doing with your wallet.

Cryptograph does not ask nor record any personal data from Torus or your account used to sign in with Torus.

You can create/use one Torus wallet per one-click login method (e.g. Google, Apple, Twitter). If you have already created a Torus wallet, make sure to use the same one-click login method if you want to access that wallet.

Unfortunately, the Cryptograph website does not currently integrate WalletConnect. To use Cryptograph, we recommend you create a new Torus wallet, or export and import your wallet with MetaMask.

In the event where you would like to export your Torus wallet private key and use a different wallet provider, you can export their private key from Settings > Private Key.
Open Torus Wallet

If using Torus, go to the My Wallet tab in My Profile and click the “Torus Website” button. Sign in to your Torus wallet in that pop-up window, and then go to Transfer. Paste the wallet address of your friend, select the amount of ETH and confirm. Sending ETH usually takes less than a minute.

To log out, go to the My Wallet tab in My Profile.

Processing a transaction usually takes between 15 and 30 seconds. This is the time it takes for the blockchain to process your action and record it. Sometimes, transactions can take a few minutes if the blockchain is particularly busy. If it has been over 5 minutes and you still see a loading screen, please refresh the page and see if the action you wanted to make has happened.

The most likely scenario is that your browser or the provider of the account you use to sign in with is logging you out automatically for security reasons. This is likely to happen if you have browsed many pages on our website or a long time has elapsed since you logged in or placed a bid.

Your browser is most likely blocking the pop-up window where you need to confirm your action with your wallet. Please make sure you enable pop-ups in your browser settings. If the issue is not solved, please My Wallet

For technical reasons, only one bid/offer can be processed every ~10s on a specific Cryptograph. If many people are placing bids on the same Cryptograph your bid may not go through. If for any reason your bid or offer is not processed, your full bid amount will be refunded.

To reduce the chance of your bid being rejected because another came in before yours, you can manually increase the gas fee you pay in the confirm transaction pop-up windows in order to speed up the processing of a transaction by the blockchain. The higher the gas fee you pay, the faster and the more likely your bid is to be processed in priority when several users are bidding at the same time.
