The MOON bridge extension of the Rinkeby-xDai Arbitrary Message Bridge allows a user to transfer Moon tokens - a new method by which the r/CryptoCurrency subreddit's contributors are rewarded. The transfer may happen from the Rinkeby Testnet to the xDai chain as well as in the opposite direction.
Mediator contract at Rinkeby Mainnet:
Mediator contract at xDai chain:
Moon tokens on Rinkby
xMoon tokens on xDai
Anyone who owns MOON tokens on Rinkby can use the bridge. MOONs are locked in the mediator contract and the same amount of xMOON bridgeable tokens are minted on the xDai chain. The reverse operation burns xMOON bridgeable tokens on the xDai chain and unlocks MOON tokens on the Rinkeby Testnet.
