Sorry, for my question, but this situation hard to understand. If I get SOV on Metamask ETH adreess, I will not be able to send it or another ETH address (not Meatamsk)? Unfortunatelly, I'm not good known about RSK mainnet...
Im not sure about this but as far as i understand when you are signing use your ethereum wallet through metamask and then you configure your metamask to be able to connect with RSK main net and i think that you will able to send it to another address. The received should have connected to the RSK main net to make sure if the address exists. If you are sending to the ethereum address that never connects to the RSK mainnet and you will be losing your asset.
I have been observing it and it seems like that's correct.
I don't know about this problem, but what if I made a transaction beforehand a few moments later set to set the connection to RSK .. will it disappear? and can't read previous transactions? I think it should be read
