Substratum underwent a TokenSwap, to update their SmartContract. Because of the lack of time given prior the token swap Ethos did not support the new token from the start.

I already had SUB in my wallet, how will this affect me?

Now that the contract is supported your balance should have been updated, if this is not the case, please create a ticket.

I deposited SUB after the token swap and my balance is not updated!

The new Substratum token is now supported, if a transaction was made before 15 March and is not visible in the wallet, please create a ticket as it might need to be rescanned.

All transactions after the 15th of March will show up immediately.
