Wallet

Owner ID

The owner ID identifiers a user as a unique identifier. On twitter, this is your user ID. It is constrained to 32 bytes.

Namespace

A namespace is used to identify a command as belonging to a specific source/environment. Without the namespace, there could be collisions in the ownerId. By making wallets uniquely registered to a specific namespace, a user can have multiple wallets. For example, the Twitter source has the identifier "X".

Wallet Index

This allows for an Owner ID on a specific namespace to have multiple wallets. By default, this is assumed to be index 0 and is an optional argument.
