Everything you Need to Know About the Callisto Airdrop (Sometimes Referred to as an Ethereum Classic Fork)

There is a Callisto (CLO) airdrop planned for Ethereum Classic (ETC) holders. A snapshot will occur at block 5500000. Those who held ETC during the snapshot will get CLO coins at a 1:1 ratio during the airdrop.[1]

This page has been updated as we’ve learned more. The snapshot took place at block 5500000, the network is currently up and running.

For the official details, see this excerpt from the official Callisto.network site or see the Callisto Github. Otherwise, read our breakdown of the Callisto airdrop.

A snapshot of Ethereum Classic blockchain will be made at block 5500000 of ETC network. Each address that had ETC at its balance at the moment of block 5500000 will receive CLO in 1:1 ratio. Callisto mainnet will NOT be launched immediately after the balances snapshot. Callisto Testnet 2.0 will be launched after the snapshot of ETC balances.

It is strongly recommended to withdraw ETC from exchanges for guaranteed CLO receiving. ClassicEtherWallet will support Callisto network as soon as the mainnet will be launched.

Technically, every exchange will receive CLO at the moment of mainnet launch. Make sure that there are two options for exchanges: (1) support Callisto and grant to users or (2) hold it for themselves.

The bottomline on the Callisto Fork/Airdrop/whatever you want to call it: Be in Ethereum Classic (ETC) in a wallet where you control your private keys (like MyEtherWallet) before block 5500000, then you’ll have access a 1 Callisto for every ETC you had after the Callisto main network goes live. To see your token balance, you must configure your wallet to show Callisto (see below). Estimates for when block 5500000 will occur are March 2 – 5th, 2018.

Where is this information coming from? First and foremost I’m gleaning this off the Ethereum Commonwealth GitHub where the developer (Dexaran, who also did the DEX ICO) has published a roadmap of the “the Callisto Network Project” (the subject of our page) and the official site (linked to from the Github). There is also some documentation on the EthereumClassic forums and an article circulating around the internet in different forms. That article in all cases looks like Reinisfischer.com’s How to Prepare for Upcoming Callisto Airdrop (Ethereum Classic). Put that official source and unofficial sources together, add in my own insights into forks, and you have just about all the information on Callisto I’m working with. If something is inaccurate, it is likely because I am mistranslating the developer’s notes (so double check the Github and site for details).

Is this a fork or an airdrop?: After careful consideration, I’m not entirely sure how I’d describe Callisto. On one hand its a fork in essentially every respect, as balances are already associated with addresses. On the other hand, most sources (including the official Callisto site) are calling it an airdrop. Who am I to argue? The Devs say “Callisto is NOT a testnet or a hardfork of Ethereum Classic.” and the devs use the term airdrop.. thus I’ll use the term airdrop and not fork. UPDATE: The current site is pretty clear (previously I was trying to go through the GitHub and developer’s comments and such to piece together this information; however, the excerpt below from the site makes it clear). The CLO token event was an airdrop and the Callisto Network is an Ethereum side chain (which means it is a unique version of the Ethereum Classic protocol running parallel to Ethereum Classic and any Callisto updates can be integrated into Ethereum Classic Network as desired).

Callisto Network: a Blockchain technology, Cryptocurrency and Smart-Contracts

Callisto Network is a blockchain platform with its own cryptocurrency (CLO) that is based on Ethereum protocol, so any Callisto improvements can be applied to Ethereum Classic. Callisto is NOT a testnet or a hardfork of Ethereum Classic. Callisto Network is developed by Ethereum Commonwealth, one of three ETC development teams.

The background: This seems to be a continuation of a project known as Ethereum Commonwealth (as noted, those looking for information on Callisto would be looking at the Ethereum Commonwealth Github; the project is called “the Callisto Network Project“).

The purpose: To make a coin that is meant as a store of value and provides an incentive to hold the coin by implementing cold staking. Cold staking is a process during which you earn interest on coins by holding them for a specific length of time. The developer is also seeking to fix a few problems related to smart contract hacking and more. Read the Callisto white paper.

The ratio: The ratio is 1:1. You get 1 Callisto for every Ethereum Classic you hold in a qualifying wallet.

How to ensure you get the airdropped coins:  To get the coins from the airdrop/fork you must be in an Ethereum Classic wallet where you control your private keys (try MyEtherWallet and ClassicEtherWallet), or you must be in a platform that supports the airdrop/fork (it is hard to say which exchanges or third party wallets will support this if any). You can see a list of suggested wallets on the Callisto siteTIP: If you want to use MyEtherWallet for Ethereum classic you have to do a few steps; see: How to Send Ethereum Classic (ETC) via MyEtherWallet). Please note that third party platforms like exchanges must decide to credit users with Callisto.

How to claim your forked coins: You’ll automatically have Callisto after the fork if you were in an ETC wallet where you controlled your private keys. You will be able to claim them after the main network goes live after the snapshot (in the roadmap there is a testing period between the snapshot and the main net going live). After the airdrop, all you should have to do is configure an Ethereum Classic wallet like MyEtherWallet to show the Callisto token, you can also use one of the wallets suggested on the site which include Trust Wallet app and Guarda. See: How To Create a Custom Token in MyEtherWallet (How to Add a Token); the next section discusses this a bit more.

When will block 5500000 occur? The article noted above on Reinisfischer.com had estimated the block would occur March 5th… however my calculations show March 2nd. Let me walk you through my logic with that noted: ETC blocks are added to the blockchain very quickly (1 every 13.4 seconds as it stands now). As of writing this on mid-day PST February 19, 2018, the current block is 5419291. I don’t have an official approximate time to offer, but I can do some rough math. The rough math is: 13.4 seconds x 80,000 blocks = about a million seconds; 1 million seconds is about 278 hours… so the fork is about 11 and a half days out from today February 19, 2018; thus, late night PST March 2, 2018 is my guess. The problem with that guess is that blocks can be added faster or slower in practice, so I can only give a very rough estimate at this point. You can see the current block at gastracker.io, the closer we get to the block, the easier it will be to approximate the time of the snapshot.

What exchanges will Callisto trade on? The site says they have reached out to Yobit.net, ChangeNow, and HitBTC. So hopefully these exchanges and more!

When is the airdrop?: The “airdrop” AKA “when you can access your Callisto” is when the mainnet goes live, after testing, after the snapshot. No way to offer an exact timing for that. Will keep you updated.

What is a fork? A fork is when developers copy and paste the code of a coin and start a new chain. Generally the reason this is done is because developers want to take the software in a different direction, thus it isn’t a pure copy paste, but often includes a new collection of protocols and some tweaks to the code as well. Sometimes this is done because there is a lack of consensus, like with Bitcoin Cash. Sometimes developers just want to create a useful and alternative product or alternative version of the existing product, like with Callisto.

What is an airdrop? With Ethereum, smart contracts can distribute tokens. In simple terms, when conditions have been met the contract will associate tokens with addresses (the “airdrop”). Then, assuming you have the keys to that address, you can access the tokens at any point after that. All Ethereum-based ICOs use this method for distribution. To see the balance of a token associated with a wallet you must “add the token.” To add the token, you need the contract address, symbol, and decimal. Callisto is essentially a fork in many respects, but logically you are going to need to add the Callisto token like you would with an ICO where the token was “airdropped.” This is the only part I’m still unclear on from the Callisto documentation.

TIP: Any fork or airdrop can end up being real or not. We usually assume it is real if it has a Github. Thus, we tend to assume Callisto is real, but we should remember this is a sort of clever ICO and not an official fork.

late night February 30th…are you sure??? 🙂

Erik on

February 30th is a date that currently does not exist, even with a leap year day……

Thomas DeMichele
Thomas DeMichele on

Hahah. Oh. Opps.

So same logic, but March 2nd [or 5th] and not February 30th.

Michael on

You mention in your second sentence; “Those who held ETH during the snapshot will get CLO coins at a 1:1 ratio during the airdrop.” You might want to clear that up, probably just a typo, but this air drop is only for ETC holders. Not ETH.

Thomas DeMichele
Thomas DeMichele on

Thank you. That would 100% be a typo. Really appreciate the edit. Clearly one must ETC in an ETC wallet to get that ETC fork. 🙂

Bryan on

Then what? Can you just leave them in your ETC wallet until you’re ready to sell and which exchanges can you sell Callisto coins on?

Thomas DeMichele
Thomas DeMichele on

Yeah, if you were in ETC before the block in a wallet where you control your keys, like MyEtherWallet, then you necessarily have Callisto. Then, if and when and assuming Callisto gets listed on an exchange, you can send your tokens to that exchange and trade them.

dundas on

i have my etc on exodus wallet will i get the airdrop ?

Thomas DeMichele
Thomas DeMichele on

I think you technically control your private keys with exodus, so in that sense you should be able to. Check out the following two articles, this should help point you in the right direction:

https://support.exodus.io/article/128-how-do-i-receive-unsupported-erc20-tokens (this isn’t an ERC20 token, it is a ERC223 token, but same basic logic applies) https://github.com/EthereumCommonwealth/ERC223-token-standard)

Is there any valuation price for the Callisto ?

Thomas DeMichele
Thomas DeMichele on

No. In simple terms, there is no way to value it really until it starts trading on exchanges. You could try by looking at the cost of ETC and the supply of Callisto (I’m assuming it is the same as the supply of ETC given the 1:1 ratio) and then you can compare that to historic prices of historic forks… but that is at best going to leave you speculating.

Al Coburne on

I think whoever wrote this article should at learn the proper name of the subject he’s writing about. The new coin not ‘Castillo’ . Now go get your shine box, jack #$#.

Thomas DeMichele
Thomas DeMichele on

Dyslexia strikes again.

Thanks for pointing that out.

For some reason my brain said Callisto, but my fingers type Castillo a few places on the page. Embarrassing, but it is what it is (and unfortunately the copy editor didn’t catch it).

Fixed it, so can’t say I’m not grateful for you pointing it out.

Prior to this article, the information on Callisto was pretty sparse. So -1 point for my typeo, but hopefully at least +1 point for creating a page that allows people access to information about the project (and some typeo project called Castillo as a bonus!)

How can CLO be claimed if ETC is held in the Exodus wallet?

Thomas DeMichele
Thomas DeMichele on

This explains it well enough: https://support.exodus.io/article/203-how-can-i-claim-my–forked-coins

Please take extra care to “be extremely careful with your private keys” as noted. It is best practices to move funds out of a wallet before importing your private keys into a new wallet as a general rule of thumb (but see the notes below).

The above said. You can use a platform like MyEtherWallet of EthereumClassicWallet for Callisto since it is a token. This makes life considerably easier and safer since you really aren’t importing your keys into anything (although you are using them to access the wallet which does have very specific risks you can read about on the websites of the aforementioned). Essentially, and for example, you could use your private keys to access your account via MyEtherWallet and then load the Callisto token (if I’m understanding how Exodus works correctly); you aren’t using a new wallet that just got launched, so you are taking less risks.

Pretty clear ,thank you!

I have my ETC in KRAKEN. Is this enough or I do need to open an account on a platform like MyEtherWallet?

Thomas DeMichele
Thomas DeMichele on

So general answer to that question is:

1. Unless Kraken supports the fork, being on Kraken isn’t enough (this is the same for any exchange).

2. You don’t really create a MyEtherWallet. It helps you generate a pair of keys and access the Ethereum and Ethereum classic blockchains. Semantics aside, you would essentially need to create an address in MyEtherWallet and move your ETC there. Then you should be able to configure that wallet once Callisto goes live.

Mike on

Thanks.
I will do this.

Student on

Is there any exchange which has announced to credit Callisto?

Thomas DeMichele
Thomas DeMichele on

Not to my knowledge. I’m keeping an eye out though.

Bo on

I don’t get it, do I have to convert my ETC coins to CLO?
What if I do nothing and hold on to my ETC coins?

Thomas DeMichele
Thomas DeMichele on

You just need to hold your ETC in a wallet where you control your private keys (more specifically, you need to be in control of your private keys AKA have knowledge of them). In simple terms, you could thus use MyEtherWallet configured for Ethereum Classic or use the official Ethereum Classic Wallet to store your ETC at the time of the fork/airdrop/whatever we want to all it.

If you have ETC and are in control of the private keys associated with it, you’ll be able to configure that wallet to store CLO.

Or at least, this is logically how it would work based on my understanding of what the Callisto developers are doing.

You don’t covert the coins, you simply also own coins on the new chain since the new chain is going to be a copy of the old chain.

Cristi M on

Any ideas if we can sell ETC now, once the snapshot was made? Or we have to wait until the main network goes live and we get our CLO?

Thomas DeMichele
Thomas DeMichele on

You can sell the second the snapshot block is added to the blockchain. Anyone holding ETC during or prior to that block necessarily will hold the new coin (since the accounts and all balances will be the same).

So you have to “be in before the block,” but then can do whatever you want after the block.

Does that make sense?

Cristi M on

Yep, thanks a lot 🙂

How can I add CLO in myetherwallet,Do you know what is the Contract address , decimal and symbol?

Thomas DeMichele
Thomas DeMichele on

I don’t know the answer to this yet. For now the point is moot because we still need to wait for the mainnet to go live. Keep an eye on the official site and Github (i’ll be doing the same so I can update the page).

Francesco on

Hello! Where is posible take a information (address, decimales, etc…) to configuración my classi Etherum wallet and to see my New CLO (Callisto) after de AirDrop? Thanks

Thomas DeMichele
Thomas DeMichele on

Can’t do this until the mainnet launches. Once it does I assume the information will be on the site listed above. I’ll be keeping an eye out for it. Right now I’m working on the assumption that it’ll work this way based on what the developer has said. I can’t find a contract with this information on it on the Github, but that might be on me. If anyone finds it, let me know 😀

Ethereum Classic Fork is gone ? on

Hello,
I transferred all of my Ethereum Classic coins to classic ether wallet (https://ethereumproject.github.io/etherwallet/) at March 3 and before the fork.
Today , three days after the fork (3/8/2018) , I’m not granted with #CLO coin unfortunately.
What Can I do now?

Thomas DeMichele
Thomas DeMichele on

You should be on track to get CLO, you have to wait until the network launches (think they are still running test network 2.0 right now).

Essentially you won’t know when the airdrop has occurred without checking the site. It is like with an ICO, they airdrop your tokens, but you can’t see the balance until you add the token (or at least, logically it should be like this). I’ll update the page the second I know, for now, if you did everything else right you can move your ETC and are simply in wait mode.
