Current Limitations

Untyped callback values

Currently, the callback values are not typed and instead just returned as raw bytes. This is a limitation of the current implementation and not a fundamental limitation of the Arcium protocol. The implementation will be updated very soon to support typed callback values.

Output sizes

Outputs of encrypted instructions should be able to fit in a single solana transaction (the callback transaction), otherwise you need to setup additional infrastructure to handle transaction data handling via callback server.
