# scUSD/scETH veNFT

### Trevee Earn **veNFT follow the ve(3, 3) design.**

VotingEscrow and Voter contracts have been forked from [Thena](https://docs.thena.fi/thena) and slightly modified to add a voting approval logic.\
\
To acquire a veNFT, users create a lock by specifying an amount of stkscToken and a lock duration. Active veNFT have a “balance”, which is the locked amount, prorated from the maximum locking duration (52 weeks). The “balance” does not represent the amount of underlying token locked, it does only count the vote power of the veNFT.

{% hint style="info" %}
Example : A veNFT with a locked amount of 5200 stscToken and a duration of one week will have a “balance” of 100 ((5200 / 52) \* 1).
{% endhint %}

The veNFTs “balances” are used by the voter contracts when a user votes for protocol gauges.\
When a veNFT is used to cast a vote, it becomes frozen until the voting period is over or the veNFT is reseted.

## 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://docs.trevee.xyz/trevee-earn/sonic-scassets/developers/scusd-sceth-venft.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.
