CryptoKnights is a multichain game, meaning that the in-game assets can be imported from and withdrawn to multiple blockchains.

RUBY as a Cross-Chain Token

For our RUBY token to exist on multiple chains, we incorporated a special type of ERC20 contract that can be aware of its balance on other chains, so that the total amount of RUBY on all chains it has been deployed on remains constant.

NFT Bridging

The NFTs in CryptoKnights will first be auctioned on a single blockchain, then can be imported into the game and withdrawn onto other chains.

The Game is a Bridge

Therefore the game serves as a bridge for all those tokens.
