They are spanish (probably) as they partnered with Wikibank (which is spanish too).
But I don't understand why tokens are selling on uniswap already, while they will have token sale only on September 22? And according info on their site they have 300 mln tokens, but according Etherscan they have 314 mln tokens already.

Is there a representative from Fuse team that can answer queries here from the community? And clarify about the token sale and the current movement in uniswap. Also, the supply not tallying? If they have live use cases, they have good foundation already. But where are those users coming from?
Maybe OP can summon the team here, since it was the question that only can be answered by the team. Even though there is a telegram group
https://t.me/fuseio, don't know they are so active right there or now, community maybe agree the presence of the team in this thread is also required.
