There are only 30M LEO. There can never be more
It is irrelevant how many are on any chain. There are only 30M native LEO (now less than 29.7M as the bridges continue to reduce the supply)
When you have 1 LEO on another chain that isn’t native (Arbitrum is native), then 1 LEO is locked on Arbitrum while you operate the wrapped equivalent. When you’re done, you unwrap and it unlocks the native LEO again.
There is no LEO on multiple chains token count. The only count is the native supply
