Right now the fee is very high: 10,5% of the transferred amount.

It might change in the future, though.

If you want to bridge your LEO now, an alternative route you might want to consider is:

• selling them on Tribaldex for SWAP.HIVE,
• then swap SWAP.HIVE for SWAP.ETH,
• bridge SWAP.ETH to Ethereum
• and then use ETH to buy LEO on Arbitrum through LeoDex.

It involves more steps, but it might cost you less than bridging your LEO with the 10,5% fee.
