Swap is a really awesome tool, but it’s hella dangerous too at the moment.
Swap plugs directly into the books on the exchange, so if the exchange liquidity is low… then swap is as well. The more orders on the books at the exchange… the bigger the trades the swap tool can handle. It’s all really practical and transparent, no magic.
Swap basically is just a “market trade” tool for people that don’t want to make an account.
