Is Solana the only non-EVM chain supported by the Arcana Auth product?
Refer to the [list of supported chains - EVM and non-EVM](/state-of-the-arcana-auth.html#supported-blockchains) for details.
Can a developer choose to use some EVM-compatible chains along with Solana in an app?
No. Either EVM-compatible chain type or Solana (non-EVM-compatible chain type) chains can be used at a time in an app. When a user logs into an app that is enabled for Solana the keys (wallet address) are different from the one assigned to the same user when EVM-compatible chain is selected.
