To make a digital currency payment from your CoinJar:
- Sign in and select the Payments tab.
- Select the account you would like to send from.
- Enter your Ethereum addresses under 'send to'.
- Enter the amount you wish to send and select 'Review and Confirm'.
If you're sending from an account other than your Ethereum account, a currency conversion rate will be presented to you when confirming the payment. To prevent any confusion when sending currencies of one type to another, a 'to' and 'from' currency symbol will be displayed.
Important: CoinJar does not support Ethereum Classic for sending or receiving. Because Ethereum Classic (ETC) addresses cannot be distinguished from Ethereum (ETH) addresses, entering an Ethereum Classic address will always result in that amount being sent on the Ethereum network, which will cause loss of funds.
Ethereum transactions not being recognised by another exchange or wallet
CoinJar sends Ethereum payments via a 'contract address', as opposed to a stand-alone Ethereum address. This is done to ensure funds held by CoinJar are as safe as possible.
While this is standard among most exchanges and wallets, some are unable to recognise funds sent in this manner, even though the Ether has successfully arrived. Unfortunately, until these parties expand their Ethereum capabilities, any un-recognised transaction will need to be manually credited by the exchange or wallet operator. Providing your receiving wallet host with your blockchain transaction ID will allow them to resolve this.
Sent payments being displayed as having no value on the blockchain
Another result of structuring Ethereum payments in this way is that blockchain explorers display '0 Ether' or '$0.00 USD' under the 'Value' field. While the initial transaction doesn't contain your funds, it informs the CoinJar Ethereum contract to forward your payment to the Ethereum address you specified.
The funds have been sent successfully - blockchain explorers will typically quote this amount and your destination address under the 'To:' or 'Actions' field.
Sending to ICO Addresses
CoinJar does not currently support ETH payments to ICO (Initial Coin Offering) addresses, and any payments to ICO addresses will fail to confirm on the blockchain if sent. In order to make any outgoing Ethereum payments using CoinJar, you are required to confirm you are not sending to an ICO address.
