Gst big price difference between two different dex

Just a newbie question here. I just noticed that there is a big price gap from gst token. In pancakeswap(binance smart chain) the gst token if you look it up right now the value is at 12$, while compared to jup & orca(solana) the value is only 6$. What is the reason of this big difference? Also If i buy from solana chain is it possible to sell it in pancakeswap? I tried allbridge but gst is not available. Is there any way in how to transfer the gst token between this two different dex? Thanks for any insight or answer for this matter.
