# Reward Distribution

**To enhance the transparency** of the VeBetter platform and x2earn apps, following also the ["dApp Tracker" proposal](https://governance.vebetterdao.org/proposals/48098052949649968323435845011935575242371156821795293696975298342916966237360), we have developed a centralized reward distributor contract. This contract must be used by the apps to ensure that every transfer of a B3TR token related to a sustainable action is publicly tracked and accessible to the community.

You need to call this contract to distribute the rewards.

### Round Attribution

By default, when you distribute a reward, the action is recorded in the **current round**. If your app allows users to accumulate actions and claim them later, the action will be attributed to the round when the claim happens — not when the action was performed.

To attribute actions to the correct round, use the `ForRound` variants of the distribution functions. These accept an additional `actionRound` parameter (the round ID when the action was actually performed):

* `distributeRewardForRound`
* `distributeRewardWithProofForRound`
* `distributeRewardWithProofAndMetadataForRound`

The `actionRound` must be greater than 0.
