Staking $RAIL gives you $ETH beta through the $RAIL itself, but also additional $ETH and stable farming to boot. One of the smartest ways to get privacy exposure without missing out on blue chips.
RAILGUN's design is structurally long Ethereum.
Most of the protocol treasury sits in $ETH. A third of $RAIL staking rewards (funded by protocol growth) is paid in $ETH.
Growth stays on the base layer.
