RAIL Token Overview
RAILGUN on Polygon and BSC have their own DAOs & tokens which are not the same as the DA or token on Ethereum. There is currently no liquidity for RAILPOLY or RAILBSC but tokens can be bought or sold OTC.
RAILGUN on Arbitrum (and future Ethereum Layer 2s) is governed by the DAO on Ethereum and thus L2 value and voting power accrues to the Ethereum RAIL token.
