xMOONS are a separate token (different than the tMOONS created specifically for the challenge). xMOONS are also bridged from Rinkeby MOONS. xMOONS are used to implement experimental features on xDai such as the xMoon.exchange and have their own tokenomics. See this section for xMOONS use-cases.
Gas limit to call method in the xDai chain: 3000000
Finalization rate: 2 block
Token transfers are enabled through a bridge extension (a set of mediator contracts). Bridge extensions may be deployed on top of the AMB for specific transfer functionality. The deployed mediator contracts do not require a set of oracles to be setup.
