How to swap an Ethereum ERC-20 and Neo NEP5 token with a smart contract?

Question

I am trying to understand how to swap tokens between blockchains please help

Answer 1

Each blockchain is its own separate administration. Therefore it is not possible to swap tokens on-chain as you would need the first chain to rely on stuff that happens on another chain.

To do something like this, usually, you need a third party that guarantees that the exchange happens correctly.
