Today’s Calls and Tomorrow’s News for Future Growth

We have received a lot of  email requests on how to claim the Callisto ($CLO) tokens, which you are eligible to get if you hold Ethereum Classic ($ETC) by block 5,500,000, so here's a summary of all you need to know to get your Callistos. Gotta catch 'em all right!?

Mainnet Is Live

Callisto Support Update:

Less than 24 hours left before the mainnet launch. The countdown is running on

Sharing is caring, right? We are happy to announce the following milestones:
Main net launch: 15 April
Test net 3.0 already online
Updated whitepaper v. 1.2a

When is the airdrop?

The “airdrop” AKA “when you can access your Callisto” is when the main net goes live, after testing, and after the snapshot.

How to stay safe from replay attack?

  • **NOTE**: Callisto (CLO) is open to replay attacks, since it will implement cross-chain functionality in the future. This means if you have your ETC and CLO at the same address, and you send out ETC, someone can double spend your CLO. This could work the other way around as well, unfortunately.  To fix/block this potential, you can just make sure to send an outgoing transaction from the wallet you're recieving our CLOS. This means that sending your ETC to, say Classic Ether Wallet, is not enough to be safe.
    • You should send ETC to desired address
    • Then send at least one transaction (small or large), out.
      • This will raise your nonce from 0 to 1. The airdropped CLO will be default set to 0, and that is what allows for reply attack vulnerability.

What is the Callisto Network?

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.

Callisto fundamentals

  1. Smart-contract ecosystem security: The main problem of Ethereum is that even a single mistake in a certain smart-contract can lead to disastrous consequences for the whole ecosystem. Unfortunately, professional audit of a smart-contract is relatively expensive. As a result, many developers neglect it and eventually the entire ecosystem is saturated with a huge number of insecure contracts. Let me remind TheDAO hack, Parity Multisig first hack, Parity Multisig second hack, ERC20 token standard insecurity (still not fixed). 

    Callisto will address this problem by introducing an "Official Smart-contract auditing department of Ethereum Commonwealth". Smart-contract auditors will be paid at protocol level (analogue of smart-contract treasury), thus auditing will be completely free for smart-contract developers. Callisto & Ethereum Classic will be the only platform with built-in security enhancements mechanism. 

  2. Scalability of ETC & CLO: We do not plan to invent our own mechanisms of transactions relaying and sidechain implementations. We are looking forwards at crosschain-relation mechanisms of 3d generation blockchains (such as and AION).It is planned to improve the scalability of ETC & CLO with already-existing mechanics that prove to be effective. EOS and AION are still in development, so we are currently in researching stage.
  3. Protocol-level enhancements: ETC community is very conservative. Some of the ETC improvements will come out at CLO network regardless of whether it will be accepted by two other development teams of ETC or not. For example: cold staking protocol and on-chain governance system.

Ethereum Commonwealth will continue ETC & CLO development.

When will the fork/snapshot happen?

Update: The snapshot has been taken, on Mon, 05 Mar 2018 14:56:37 GMT!

We have created an easy to follow countdown page with a timer, and current block. The magical block of 5,500,00 appears to commencing sometime on March 5th. This countdown page is very useful as the exact time/date can fluctuate depending on current hashing and difficulty of the network. That being said, glitches do happen with pretty much anything based on technology, so be sure to cross reference with the options below.

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 every respect, but logically you are going to need to add the Callisto token like you would with an ICO where the token was “airdropped.”

Will my exchange support the airdrop?

No one knows except for the exchanges themselves, and at this point, none have made any official announcements for support and issuance of the CLO tokens for ETC hodlers. Technically, the free coins are also dropped for $ETC held on an exchange, but it depends on the exchange if they issue them to you. So if you're interested in getting Callisto tokens, we recommend NOT to keep your Ethereum Classic on an exchange.

Which wallets support the airdrop?

These two wallets are guaranteed to issue the Callisto coins:
Pretty much every wallet which allows exporting accounts are eligible to claim CLO. Here are a few specific for sure safe storage places.

  • ClassicEtherWallet
  • Coinomi
  • Trust Wallet
  • Guarda
  • ClassicMask
  • Ledger Nano S (Hardware Wallet)
  • MyEtherWallet – To be able to use your MEW wallet for holding Ethereum Classic coins ($ETC), you have to follow this steps. After the airdrop, all you should have to do is configure an Ethereum Classic wallet like MyEtherWallet to show the Callisto token. See: How To Create a Custom Token in MyEtherWallet (How to Add a Token)
    • As you don’t physically store ETC in a wallet like MyEtherWallet or JAXX, you always should be able to claim along with your private key. Your ETCs are, like any other coin,  stored in the blockchain and wallet are only an interface to access those in a convenient way. Your coins could also be transferred by command line if you know how, so basically it should not depend on the wallet itself to claim those Callistos.  This means, technically it should be possible to get the coins with every wallet (besides wallets on exchanges) that hold ETC on block 5500000, as you basically have ETC on the ETC blockchain, tagged along with your private key. The snapshot will be generated and if you private key held ETC, CLOs are issued. However, if you just want to receive it the easy way – simply go with one of the first two wallets. The free Callisto coins should automagically appear in your wallet after the hard fork.To stay updated, you might want to keep an eye on their official Twitter account and their Reddit.

How much CLO do I get?

The Callisto airdrop will be a 1:1 ratio to the Ethereum Classic held. So you will receive 1 CLO token, for each 1 ETC token held on


Note: Any fork or airdrop can change, or be called off at any time. A main reference to legitimacy is a projects Github. Thus, we tend to believe Callisto is real, but we should remember this is a sort of clever ICO and not an official fork.
