I tried the Wormhole Bridge today and bridged $LUNA to Solana and back to Terra. It was a small amount of less than 20 $LUNA.
One notable observation: Bridging back to Terra cost me c. 0.5 $LUNA . These are the tx fees purely on the Terra Blockchain.
Question: What can be done to bring the cost down? And who would be able to look into this closer (Terraform Labs?) ?
