# VRF Rewards

> Mint random rewards on an Ephemeral Rollup with a delegated reward account, verifiable randomness from the VRF oracle, and commit-back settlement to Solana.

The VRF Rewards example mints random rewards for a delegated account on an Ephemeral Rollup. The
program requests randomness on the ER, the VRF oracle fulfills it by invoking the program's callback
with verified random bytes, the program derives the reward from those bytes, and the state commits
back to the base layer.

## What the example demonstrates

* **VRF on a delegated account:** the reward account lives on the ER, so randomness requests and
  reward minting run at rollup speed.
* **Oracle callback pattern:** the program exposes a callback instruction that only the VRF oracle
  can fulfill, receiving verified random bytes on-chain.
* **Randomness-derived state:** reward selection happens deterministically from the verified bytes —
  no off-chain draw to trust.
* **Commit-back settlement:** the final reward state is committed from the ER back to Solana, ready
  for base-layer payouts.
