What are they building on Celo?
Celo integration into Anthem
The Celo Anthem integration allows CELO token holders to participate in staking and governance with Ledger devices. In addition, any Celo account can be inspected to see details about its portfolio and transaction history, most importantly the staking rewards earned over time. All account data is also exportable as a CSV file to help stakers with their accounting. Anthem is the first UI to stake CELO tokens in a non-custodial manner and the first explorer with historical data on Celo accounts. Visit https://anthem.chorus.one to try it out yourself.
