# Our Features

## Carbon native assets

Carbon is the native asset runtime for tokens and NFTs on Phantasma Phoenix. Asset operations (create, mint, transfer, burn) are built into the chain, so standard token and NFT flows do not require custom smart contracts or VM execution. Metadata is schema-validated by the chain. See the full overview: [Carbon: Native Assets on Phantasma Phoenix](/main/about/carbon.md).

## SmartNFTs (dynamic NFTs)

SmartNFTs extend Carbon with VM-driven logic for NFTs that can evolve and update their content based on defined rules. In the current developer flow, this means using token-backed contract workflows: create a token with VM code, or attach VM code to an existing token, then upgrade that token-backed contract over time if needed.

## NFT addresses and infusion

Each NFT has its own Carbon address derived from its token id and instance id. Assets sent to that address become attached to the NFT, enabling nested ownership. Infusion is supported by both Carbon NFTs and SmartNFTs.

## Dual Token Economy

*Govern with SOUL - Fuel your experience with KCAL*

SOUL and KCAL work together in the Phantasma economy.

**SOUL**

* Core token used for staking and governance.
* Staking SOUL mints KCAL.

**KCAL**

* Fuel token used for transaction fees and on-chain operations.

## Carbon-negative footprint

Phantasma is the first certified carbon-negative blockchain.

## Wallet connectivity

Phantasma Link connects dApps to wallets for signing transactions and interacting with the chain.

## Tools and SDKs

Use the Token Deployment UI for Carbon workflows and contract lifecycle actions: [Token Deployment UI](/main/about/token-deployment-ui.md). Developers can also build directly with the C#, Unity, TypeScript/JavaScript, Go, Python, Rust, and C++ SDKs, or use `pha-deploy` for repeatable CLI workflows.

## On-chain storage

Phantasma includes a native storage contract for on-chain data.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://phantasma.gitbook.io/main/about/our-features.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
