On the transaction screen, what is the difference between an Exchange and a Swap ?
I may be mistaken on this, but I think that a Swap is where you swap one form of a token for an equivalent one. For example, you might Swap BTC on the Bitcoin network for rBTC which is the equivalent token on the RSK network. Since these are effectively the same underlying coin, there should be no CGT to pay on such a transaction
An Exchange is where you trade one coin for another, eg exchanging BTC for ETH
