The right network is the one both exchanges support cleanly
Before looking at raw fee levels, check whether the sending and receiving exchange support the same asset on the same network. This is the first filter because unsupported routes create real operational risk.
A faster or cheaper network is not helpful if the destination does not support the deposit route you plan to use.
- Confirm the deposit network on the receiving exchange first.
- Match the asset and the network exactly before withdrawing.
- Do not optimize for headline fees while ignoring compatibility.
