Ledger Legends is an early access trading card game that’s inspired by Gwent, the card game from the Witcher series. It’s unique among TCG’s in that it’s cards are not handled by any central authority but by a smart contract on the Ethereum blockchain. This smart contract implements the new ERC721 standard for non-fungible tokens which was pioneered by CryptoKitties. The ERC721 standard is similar to the better known ERC20 standard but it’s for tokens that cannot be substituted for another.

The importance of the cards being handled by a smart contract cannot be understated because it makes them tangible, it makes them yours for real, nobody can take them away from you and you can trade them to anyone you want. This makes Ledger Legends closer to a physical card game like Magic: The Gathering instead of a central digital one like Hearthstone.

The dueling interface, spartan but functional.

Like a physical card when you want to duel someone you go to a central place, in the real world it’s usually an Internet café or a game store, in Ledger Legends it’s the Arena Server. The Arena Server is a centralized service which you authenticate to with your Ethereum account. When you are authenticated it then fetches your cards from the ERC721 contract on the blockchain and you can use them to play with. Dueling doesn’t cost anything and does not involve a transaction, you can duel with an account with zero ETH, you can even duel with an account with zero cards, although then you would be dueling with the crummy “house deck”. All that’s needed for dueling is just a Web3 enabled browser like MetaMask and a signature from you securing that you own the private key of your account.
