# Lock YMT
First, go to the [Yamato official site](https://app.yamato.fi/#/), click “veYMT” on the top left to navigate,\
and connect with your preferred wallet by clicking the “Connect Wallet” button on the top right.\
(If you are already connected, this step is not necessary.)\
To change the connected network, click the network selection button at the top right and choose from Ethereum mainnet or Sepolia.\
You can also access the veYMT page directly from [this link](https://ve.yamato.fi/).
In the center of the page, within the “My YMT Portfolio” section, click the “Lock” button.
A popup will appear. Specify the amount of YMT to lock and the lock duration,\
then click the “Lock” button at the bottom.
If you wish to lock all your YMT, simply click the balance displayed below the input field.
Lock duration can be set in weekly increments, up to a maximum of 4 years.
The amount of veYMT you receive depends on the lock duration. You can check the exchange ratio [here](/en/ymt-yamato-dao-token.md#veymttoha).
If you haven’t approved the token yet, a “Approve Token” button will appear at the bottom.
Click it to proceed to the approval screen.
Here is an example using MetaMask.
The approval screen below will appear.
Check the spending limit and gas fee, then click the confirmation button at the bottom.
Once the approval transaction succeeds, the confirmation screen for locking will appear immediately.
Review the lock amount and gas fee, then click the confirmation button at the bottom.
When the locking transaction succeeds, the display in “My YMT Portfolio” will update as shown.
Please verify that your veYMT balance, the amount of YMT locked, and the lock end date are as expected.
For peace of mind, also check your wallet to confirm your YMT and veYMT balances.
Your YMT balance should have decreased, and your veYMT balance should have increased.
This completes the YMT locking (veYMT acquisition) process! 🎉

**To Increase Your Locked Amount**
Click the “Increase Locked Amount” button in the “My YMT Portfolio” section.
Enter the additional amount of YMT you want to lock.
If you want to lock your entire YMT balance, simply click the balance below the input field for easy input.
Once you’ve entered the amount, proceed with token approval if needed.\
If already approved, proceed directly to the locking transaction.
After the transaction succeeds, check the updated balances in “My YMT Portfolio.”
**To Extend the Lock Period**
Click the “Extend Lock Duration” button in the “My YMT Portfolio” section.
Select the extended lock period and click the “Lock” button at the bottom.
After the transaction succeeds, please confirm that the lock end date and balances have been updated in “My YMT Portfolio.”
