When one creating a so-called bridge in order to exchange a coin on one blockchain to a coin on a different blockchain, how does it work? Does it always necessitate creating an intermediate token issued by a DEX?
A scheme is:
send KSM → receive INTermediate token, 1:1
send SOL → receive KSM
send INTermediate token → receive SOL
In all the steps the tokens that get sent and received, sent and received from and to a smart contract of a DEX. Right?
Does it work this way?
