# Trader rewards

> Fund custody and immutable Merkle-root claims.

Fifteen percent of every curve fee and fifteen percent of collected permanent-LP fees are allocated to trader rewards. Curve allocations enter `TraderRewardsVaultV3` as native USDC. LP allocations enter as the collected ERC-20 asset, which can be either canonical USDC or the launch token.

The rewards vault preserves accounting by launch token and asset. Only the bound `TraderRewardsDistributorV3` can request payouts.

The distributor owner publishes an immutable Merkle root for a tuple of epoch, launch token, and asset. A claimant supplies the amount and proof; each claimant can claim once for that distribution ID. A valid proof does not reserve funds in advance.

<Warning>
  Roots are policy inputs controlled by the distributor owner. The contracts do not calculate trading eligibility onchain. Published roots can overcommit the pooled vault balance, which may cause a later valid claim to fail until more funding is available.
</Warning>

The checked-in contracts and tests prove the custody and claim mechanics, not a particular rewards schedule, eligibility policy, published root, or currently funded distribution.
