Thank you for contributing to Matchpool. We received a handful of messages about contributions sent from different popular wallets and exchanges. We acknowledge not knowing where your funds are can be unsettling so this post aims to make sure every contributor can get a status on their Guppies and view them in MyEtherWallet.
Our recommendation was to contribute to the crowdfunding via MyEtherWallet, Mist or Parity. If you sent ETH via MyEtherWallet, view our guide: How to check your GUP in MyEtherWallet.Contributing from Other Ether Wallets
Once you have imported your Private Key or Keystore (UTC/JSON) File to MyEtherWallet with your password, click ‘Show All Tokens’ on the left and your GUP will be listed like the image below.

Go to MyEtherWallet & ‘Send Tokens’ tab. Plug your Nano S, select the Ethereum App and go to the settings of the app to activate ‘Browser Support’ and ‘Contract Data’.Select the Base address you wish to manage (The Ether address you contributed with)You can now view, receive and send tokens from your Nano S from MyEtherWallet.Note that when you sign a token transaction on your Nano S, it’ll display a value of 0 (zero), a ‘WARNING data present’ and the destination address will be the token contract address (not your recipient address).
Open the Developer Menu.
If you are on macOS, the Developer menu is under Exodus (To the right
of the Apple in the menu bar). If you are using Windows or Linux, it can
be accessed by pressing Ctrl+Shift+D.
(For new users this means holding the Control key with the Shift key at
the same time and then pressing D — essentially you are pressing 3 keys
what asset you want to view the private keys to. In this example we are
going to export the private keys for Bitcoin. These steps are the same
for the other assets.Choose Developer > Assets > Bitcoin > Export Private Keys…Your private keys will be exported to a folder on your Desktop titled “exodus-exports”
Jaxx’s EthereumWallet gives you the option to export a JSON-format backup file containing your wallet details.To
do so, hover your cursor over the downward arrow at the top of your
EthereumWallet screen. If the JSON (Keystore File which you can upload
to MyEtherWallet) is still generating, it will look like the image
below:Once the load is complete, you can download the JSON and upload it into another service.
Mist & Parity
Go to Contracts and navigate to ‘Watch Contracts’.Then choose ‘Custom Contract’ and press ‘Next’.Add the Contract Address: 0xf7B098298f7C69Fc14610bf71d5e02c60792894CCopy & Paste the Contract ABI you can find in the link below: https://etherscan.io/address/0...Copy & Paste the address you sent your Ether from in the ‘balanceOf’ choice and then click on the Query button.
Exchanges & Custodial Wallets
We have sent messages to exchanges regarding contributions that came from exchange wallets. Due to high volume of support requests to exchanges, we still do not have direct answers from their support teams but we are speaking with them personally as we are working towards listing GUP on the public exchanges. Exchanges include Bittrex, Bitfinix, Poloniex, Coinbase.Coinbase & Freewallet
We have investigated Coinbase & Freewallet as they claim they are wallets on their site, however their basic wallets are managed by the company and not the users. We have had a reply from the Coinbase support team below.Hi Matchpool Team, Danielle here, with Coinbase Compliance. Your case has been forwarded to my attention and I have reviewed all prior correspondences. As you may know, digital currency funds stored on Coinbase and GDAX are stored in custodial wallets for which the private keys are managed by Coinbase/GDAX on behalf of our customers. Accordingly, customers holding funds in their Coinbase or GDAX account are unable to access the private keys associated with their public keys. This is an intended security feature which has always existed for our services. For more information, please see: https://support.coinbase.com/customer/portal/articles/1526452 Accordingly, we are unable to retrieve any ERC20 tokens (i.e., “Guppies”) associated with our customers’ public keys, as doing so would present significant platform security issues. Regretfully, this means that Matchpool ICO participants who sent funds from either their Coinbase or GDAX accounts to the Matchpool ICO address(es) are unable to retrieve Guppies associated with their Coinbase and GDAX public keys. Should you have any further questions or need anything else, we are here to help. Thanks. Respectfully, Danielle | Coinbase Compliance
We understand a small number of contributors have sent Ether from Coinbase & Freewallet. We will continue to do our best to further communicate with these companies to retrieve contributions, however we cannot promise that they are recoverable.View your GUP in MyEtherWallet
