## Splinterlands Cards Now Available on OpenSea!
The Splinterlands team is very excited to announce that Splinterlands cards can now be transferred from the game to ERC-721 tokens on the Ethereum blockchain where they can be bought, sold, and traded on the OpenSea platform!
Splinterlands runs on the Steem blockchain, and each Splinterlands card is a unique NFT that can be used to battle thousands of other players in live, PvP combat to earn crypto and other prizes.
The existing Steem-based marketplace for the cards has an average volume of over 5,000 cards sold for over $3,000 every day, and has done well over $1M of total transaction volume over the past year.
Now, for the first time, the cards are available on a new decentralized marketplace - OpenSea - where they can be bought and sold for ETH and other ERC-20 tokens!
To transfer cards to Ethereum, you select the cards you want on the card details view and choose the “Send” icon (the same one used to transfer the cards to another player). Now there will be an option to choose whether you want to send it to another player, or to the Ethereum blockchain. If you choose “Ethereum”, it will ask you to link your Ethereum wallet address to your game account. **This will require Metamask or another Web3-enabled browser or extension to be installed and available in your web browser.** You can get Metamask for your browser by going to https://metamask.io/.
There is also a new filter option on the collection and card detatil screens to see your cards that are held in your linked Ethereum wallet address. **Please note that cards that have been transferred to Ethereum may not be used in the game until they are transferred back!**
If you want to send cards from your Ethereum wallet back into the game so that they may be played, you can once again select the card in the card details view and choose the “Send” option which will allow you to transfer them back into the game. Transferring cards from Ethereum into the game requires you to sign and broadcast a transaction to the Ethereum blockchain. **This requires you to have some Ether (ETH) tokens in your Ethereum wallet in order to pay the transaction fees (known as gas).**
