is there any possible way to send ether (preferably other cryptos too) between two separate ethereum (also any other blockchains) blockchains ? also is HTLC support is needed for this to be achieved?... because it does kind of resembles an atomic swap process.
Thank you for your answers in advance :D
Edit: would the Ethereum cross-chain swap work between a private Net and the ethereum mainnet giving that we have here two different genesis block configs (for example: the private has 0 mining rewards )
