## Operational notes

<AccordionGroup>
  <Accordion title="Rebase token (stETH)">
    stETH is a rebase token — your balance increases daily as rewards accrue. 1 stETH always equals 1 ETH of staked value.
  </Accordion>

  <Accordion title="Withdrawal queue">
    Protocol withdrawals take 2–5 days depending on queue length. For instant liquidity, swap stETH on Curve or other DEXes.
  </Accordion>

  <Accordion title="wstETH">
    For DeFi composability (where rebase is problematic), use wstETH — wrapped stETH with a fixed balance but appreciating exchange rate.
  </Accordion>
