Occasionally, customers accidentally enter a wrong wallet address or find out later the wallet is not capable of managing ERC-20 tokens like the CombiCoin. Because Ethereum transactions cannot be reversed we want to make absolutely sure you registered the correct wallet before we send the CombiCoins.
After we receive your payment we will send a test payment of 10 Gwei to the wallet you registered as receiving wallet. We will wait for two to three days for a message from you the wallet is maybe not the right wallet. If we do not receive a message we will assume everything is working and we will transfer the CombiCoin tokens to your wallet.
No, this is not possible. CombiCoin is a ERC-20 token and makes use of the Ethereum network. You need your own ERC-20 compliant wallet to keep your CombiCoins.
Please do not participate using an exchange account or contract wallet. You don’t own the private key of this wallet. You will not be able to access your CombiCoins!
It is recommended that you store backups of both forms of your key (the Keystore / UTC file version and paper wallet version) in physically separate, offline environments.
This prevents loss of the private key & password due to: dead hard drive, lost USB drive, wet piece of paper, etc. Keep in mind that physical loss can affect an entire area (e.g. fire, flood).
There may be a chance that you saved the keystore file without realizing it. So, just in case:
- Do a full search of your computer for “UTC-“ and see if the private key shows up.
- Do a full search of your computer for your address without the 0x at the beginning.
- If you know when you created it, look through all files during that time period for any documents that may hold your key or screenshots.
- Generate a new wallet via https://www.myetherwallet.com/#generate-wallet and take a look and the different options you may have downloaded or saved. Sometimes that can jog your memory.
You printed your private key when you created your wallet. It might be at another location.
There’s no way for us to recover your Ethereum wallet password. You are the only person who had it when the keystore/json file containing your private key was created and encrypted.
If you have your private key printed on paper you can still use this to access your wallet and your CombiCoins.
We can not predict the future of the cryptocurrency market. There is always a risk of large price falls even for CombiCoin.
CombiCoin is an ERC20 tokens issued on the Ethereum blockchain. Token holders can store and manage their tokens using existing ERC-20 compliant Ethereum clients including official Ethereum wallets like MyEtherWallet, Metamask, Parity, Mist and the latest versions of Nano Ledger S and Trezor. You need your own wallet with your own private key to keep your CombiCoins. Phone wallets like Freewallet do not support CombiCoin tokens at this time.
Metamask provides extra security when accessing your Ethereum wallet. Below is a tutorial on the benefits and how install the plugin in your browser.

CombiCoin is an ERC-20 compliant token. Any ERC-20 tokens can be stored at your Ethereum address in Exodus. The problem is that you won’t be able to see or manage the tokens in Exodus. If we send CombiCoin tokens to your Exodus wallet, it will be stored at your wallet address, but Exodus will not display it. You can check your token balance on https://etherscan.io/ by pasting in your wallet address, and checking the token tracker drop-down.
