# Lock Supply

> Lock tokens from your dev wallet for a set period, through Streamflow on Solana or HoodLock on Robinhood.

### Locking supply

You can lock tokens directly from the trading page. Ora runs the process through a lock provider that depends on your token's chain, so you only set the amount and the duration.

### Lock provider

The provider's name sits above the **Lock** button, and the lock modal is titled after it.

**Tab: Solana**

Tokens are locked with [Streamflow](https://streamflow.finance/).

* **Fee:** Streamflow charges about 0.15 to 0.2 SOL, plus 0.5% of the locked tokens.
* **Balance needed:** your dev wallet needs at least 0.16 SOL to cover the fee.

**Tab: Robinhood**

Tokens are locked with **HoodLock**.

* **Fee:** HoodLock charges a flat on-chain fee, about 0.005 ETH.
* **Balance needed:** your dev wallet needs at least 0.01 ETH to cover the fee.

### How to lock your supply

1. Click **Lock** at the top of the token page.
2. Your dev wallet is selected. Locking is only possible from the dev wallet.
3. Set the amount to lock: type a custom value, click **MAX**, or use the slider.
4. Set the unlock time in **Months**, **Days** and **Hours**, or pick a date with the calendar icon. The shortest lock is one hour, and the modal shows how long until the tokens unlock.
5. Click **Lock**. A notification confirms the lock.

If your dev wallet doesn't hold enough SOL or ETH for the provider's fee, the modal tells you how much is needed and the **Lock** button stays disabled.

To see your past locks, click the history icon in the modal header. **Lock History** shows each locked amount, its unlock date and its **Contract ID**.
