# CAIP-19

*For context, see the [CAIP-19][] specification.*

## Rationale

On Stacks, there are three types of native assets: STX, fungible tokens and non-fungible tokens. STX tokens are exposed to the users,
the two others are only internal to smart contracts defined by the programming language Clarity. A Stacks smart contract can define
more than one native fungible or non-fungible token to allow detailed control over assets.

Smart contracts that contain only one fungible token, resp. one non-fungible token defines a Stacks fungible token (FT),
resp. a Stacks non-fungible token (NFT). There are corresponding standards (SIP) exposing token functions to the user.


## Syntax

After the [CAIP-2][] (namespace+chainID), a slash defines an `asset_namespace` and an `asset_reference`.
The `asset_namespace` is defined via the SIP or

I'm sorry but I don't see any explanation of the .megapont-space-agency segment in ## Syntax section, nor would it be allowed by Stacks/caip10 or by caip19 itself... is it really necessary or should that information/disambiguation mechanism live elsewhere, for example, in a query or matrix parameter at the end of the URI?

The stacks/caip10 syntax is case-insensitive (or all-caps, to be more precise) which I assume is carried over from the Stacks native addressing system. Would it make sense or simplify things for this naming convention to match, to reduce the phishing/impersonation vector of i/I/l/L ambiguities, etc etc?
