# Nftfee Contract

NFT Fee processes held USDT in rounds and allocates it to Node NFT and Super Node NFT holders. Holders read distribution progress here; user claims are made through NFT Dividend.

### Round queries

| Function                    | Purpose                                                        |
| --------------------------- | -------------------------------------------------------------- |
| `activeRoundId()`           | Current round; `0` means no active round                       |
| `nextRoundId()`             | Next round identifier                                          |
| `getActiveRoundProgress()`  | Current phase and processing cursors                           |
| `getRoundAmounts(roundId)`  | Total, category amounts, per-NFT values, dust, and allocations |
| `getRoundProgress(roundId)` | Snapshot counts, cursors, timestamps, and completion flags     |

Read `NODE_SHARE_BPS()` with `DENOMINATOR()` for the category split. The published source allocates 50% to each NFT category. An address's allocation also depends on the number held in the round snapshot.

`nftdiv()` and `finalizeRound()` are executor-only state changes, not holder claim functions. Holders should query `NFTDividend.getUserDividendInfo(user)`.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://document.sunprotocol.io/en/smart-contracts/nftfee-contract.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
