## How vaults work

1. **Deposit** — Supply assets to a vault
2. **Earn** — Vault deploys capital across strategies; rewards auto-compound
3. **Withdraw** — Redeem shares for underlying (subject to vault liquidity/queues)

<Note>
  Vaults abstract strategy complexity. Users deposit a single asset; the vault manages allocation, harvesting, and compounding.
</Note>
