ieo is tomorrow, don't know about test net

The IEO is scheduled for 28th May, though at this point I don't think there's time for KYC verification which is required. You can check the details in the official Kucoin announcement: https://www.kucoin.com/news/en-announcement-of-chromia-chr-token-sale-on-kucoin-spotlight

Testnet is launching as we speak, and mainnet is due for end of July!
