# Lockup & withdrawals

Every Chamber deposit has a lockup of **up to 24 hours**, after which you can withdraw any time. Withdrawals work in one of two ways: cash out as a single asset (Chamber swaps the vault's holdings for you), or redeem a pro-rata slice of the actual underlying basket.

## The 24-hour lockup

After a deposit, your vault shares are locked before you can withdraw them.

* A **fresh deposit** (no existing position in the vault) starts a full **24-hour** timer.
* A **top-up** on top of an existing position applies a **weighted** lockup: the added lock time is proportional to how much you added relative to what you already held. A small top-up on a large existing position adds only a small amount of lock time (seconds or minutes). A large top-up adds something closer to the full 24 hours.
* The gate applies to your **whole balance in that vault**, not just the new shares. During the lockup window, the entire position is locked.
* The lockup applies to **everyone**, including the manager.

It's a flash-loan protection measure: it blocks same-block manipulation patterns. It is **not** a redemption queue or a manager-controlled gate. Once the window passes, your shares behave like any other ERC-20: you can withdraw, transfer, or hold.

## Two withdrawal methods

When you open the Withdraw modal on a vault page, you pick one of two methods.

### Single-asset withdrawal

You specify which asset you want out (usually USDC). The vault liquidates a pro-rata slice of its holdings and returns the target asset to you.

* **Pros.** Simplest outcome: you get one clean token.
* **Cons.** Involves internal swaps at current market rates, which means slippage and swap fees eat into your withdrawal. On a thin market or a volatile day, that can be noticeable.

### Underlying basket withdrawal

You receive a pro-rata slice of whatever the vault currently holds. If the vault is 60% USDC / 30% WETH / 10% aUSDC, you get 60%/30%/10% of your share value in each.

* **Pros.** No market swaps on plain token holdings: you get those out directly, no slippage or swap fees.
* **Caveat.** If the vault holds LP tokens, lending positions, or other complex assets, the protocol still has to *unwind* them to hand you the underlying. That's not a market swap, but it costs gas for the unwind steps and, in some cases, protocol-side costs (e.g. unstaking, withdrawing from a lending pool).
* **Cons.** You have to handle the basket yourself. Some positions aren't trivially tradeable out in one click; you may need to unwind them manually.

For most depositors, **single-asset is the default**. Use basket if the vault has a clean, liquid composition or if you want the individual positions for your own reasons.

## The withdrawal flow

1. **Open the vault page** in the [Chamber app](https://chamberfi.com/).
2. **Click Withdraw.** You'll see your current share balance, its USD value, and any exit fee.
3. **Pick the method**: single-asset or underlying basket.
4. **Enter the amount** of shares to redeem. You can part-withdraw; you don't have to exit fully.
5. **Sign the transaction.** Assets return to your wallet once mined.

## Fees on withdrawal

The vault's exit fee (0–2% depending on the vault, set by the manager) applies to both methods. Performance fees are already accounted for continuously and aren't re-charged at withdrawal. See [Fees](/deposit/fees.md).

## Common questions

**What if the vault holds an illiquid asset when I want to withdraw?** Single-asset withdrawal may have more slippage than usual; basket withdrawal hands you the illiquid token directly. In extreme cases (e.g. a single underlying market is frozen), withdrawals can be temporarily difficult (see [Risks](/deposit/risks.md)).

**Can I withdraw a fraction of my shares?** Yes. Enter any amount up to your balance.

**Is there a withdrawal queue?** No. Withdrawals are immediate once the lockup has passed. You don't wait for a manager action or a redemption window.

**What if I deposit, then need to withdraw right away?** You can't. The lockup is enforced onchain. For a fresh deposit that's up to 24 hours; for a small top-up on an existing position it can be much shorter. Plan around it rather than depositing funds you might urgently need.
