Metronome proposes multi chain portability to achieve endurance and enhance decentralization.
In a system managed by autonomous smart contracts, decentralization provides MTN community with self governance.
Portability is an key feature of the project. Cross chain property allows tokens to longer endurance in the event new, smarter chains are available and mainstream.
One positive result of cross-chain ability could be broader price discovery. And if trading interest gets critical mass in multiple chains this could grant greater price stability to MTN.
