Thank you for contributing on testnet!
For testnet users we communicated an XP claim at the end of the testnet phase. We gave all testnet users XP to be used on mainnet, even if they didn't have an account! You can read about that here: https://www.ethos.network/post/ethos-is-live-on-base-mainnet
We have since closed the claim with the pre-season. You will not long be able to claim that XP.
Ethos will NOT give invites out for participation on testnet.
You'll still need to be invited by someone now that Ethos is live.
You can find a directory of people who have invites at https://app.ethos.network/directory to see if any of your friends may have one!
