@rossneilson How can this be tested?

[rossneilson]

We have a new token that can be transferred, should show as ethereum on testnet and goerli

[Filipv95]

@rossneilson I've check this, new token is visible as 'ETH' in Transfer&Mint action, but I am unable to finish creating Proposal, is this perhaps expected behavior on localhost?
