Every Ethereum transaction requires gas fee. Will the end-user be expected to pay for gas?

We aim to provide smooth user experience and quick adoption of FLIP, especially for novice users who are not familiar with Ethereum. Thus, we likely will offer an off-chain solution to make gas fee less transparent, or at the very least, not a barrier for adoption of FLIP.

We still want to retain a small "cost" for escrowing a digital item, however, because we need to prevent spamming the blockchain.
