Title: Atomic swap fee limitation Post by: youstock on February 14, 2018, 04:02:38 AM Until https://github.com/ethereum/EIPs/pull/877 or something similar is implemented, there is a major drawback to atomic swaps between bitcoin based coins and ethereum based coins. Namely, users receiving ethereum from an atomic swap are required to already own some ether in order to execute the redeem transaction call. This is a big limitation for new users trying to get their first ethers or aura from a decentralized exchange. In bitcoin based coins, this just comes from the input, since the htlc contract works just like any other transaction input that pays the mining fee.
