Once you've locked BTC and received your veBTC NFT, you can manage your position, extend your lock, and claim rewards.

## Viewing Position Details

Navigate to the Lock page to see:

- **BTC locked** — Amount in your position
- **Current veBTC** — Your voting power right now
- **Lock expiration** — When you can withdraw
- **Earnings** — Accumulated rewards

---

## Extending Your Lock

Maintain voting power by extending the lock duration before its expiration.

1. Go to the Lock page

2. Select your veBTC position

3. Click **Extend Lock**

4. Select your new duration (1–28 days)

5. Confirm the extension

Extending resets your voting weight based on the new lock duration.

## Claiming Rewards

Voting rewards accrue throughout each epoch and become claimable once the epoch ends.

1. Navigate to your veBTC position

2. Click **Claim Rewards**

3. Receive your earned fees and incentives

Rewards are paid out in the tokens generated by the pools you voted on.

> **Note:**
>
> Rewards don't compound automatically. You must claim and redeploy them manually.

### Claim Window

You can claim chain fees accumulated over the epoch when the following epoch starts. Unclaimed earnings will continue to accumulate, but are only available for claim for **50 epochs**. Any unclaimed fees after this period are lost.

## After Lock Expiration

Once your lock expires, your voting power reaches zero and you can withdraw your BTC. You have three options:

- **Create a new lock** — Lock again to regain voting power
- **Wait** — Your BTC remains safe; you can decide later
- **Withdraw** — Return your BTC to your wallet

To withdraw:

1. Navigate to your expired position

2. Click **Withdraw**

3. Your original BTC is returned to your wallet and the veBTC NFT is burned
