A 3DCoin wallet is as simple as a single pairing of a 3DCoin address with its corresponding 3DCoin private key. Such a wallet has been generated for you in your web browser and is displayed above.
To safeguard this wallet you must print or otherwise record the 3DCoin address and private key. It is important to make a backup copy of the private key and store it in a safe location. This site does not have knowledge of your private key. If you are familiar with PGP you can download this all-in-one HTML page and check that you have an authentic version from the author of this site by matching the SHA256 hash of this HTML with the SHA256 hash available in the signed version history document linked on the footer of this site. If you leave/refresh the site or press the "Generate New Address" button then a new private key will be generated and the previously displayed private key will not be retrievable. Your 3DCoin private key should be kept a secret. Whomever you share the private key with has access to spend all the 3dcoins associated with that address. If you print your wallet then store it in a zip lock bag to keep it safe from water. Treat a paper wallet like cash.
Add funds to this wallet by instructing others to send 3dcoins to your 3DCoin address.
Check your balance by going to 3dcstats.info or 3dcoin.io and entering your 3DCoin address.
Spend your 3dcoins by going to 3dcstats.info and sweep the full balance of your private key into your account at their website. You can also spend your funds by downloading one of the popular bitcoin p2p clients and importing your private key to the p2p client wallet. Keep in mind when you import your single key to a bitcoin p2p client and spend funds your key will be bundled with other private keys in the p2p client wallet. When you perform a transaction your change will be sent to another bitcoin address within the p2p client wallet. You must then backup the p2p client wallet and keep it safe as your remaining 3dcoins will be stored there. Satoshi advised that one should never delete a wallet.
