# 2. Approve MANTA.

Hopefully, by now you should have acquired some **MANTA**. Next, you need to approve Battledogs Arena to use your **MANTA** during gameplay.

This is a **brilliant** button inside the game.

​

As with the standard practice for marketplaces and gaming, we need approval to utilize your **MANTA** tokens, this is so you don't have to approve each time you play. It also increases your response time if you have to act fast for any reason.

For your **security concerns**, we also included a **Revoke** button beneath our approval button on our UI, so that **you can easily revoke platform access to your tokens at any time**. The revoke button is a darker button right beneath the brilliant golden checkmark button. Click on this button anytime to revoke platform access. We make it that easy.

​

It is important to note during gameplay, **The Informant** can be **hovered over** at any time to inform you of how much **WETH** approval you have left. The lesser your approval is, i.e. the closer to zero, the more **The Informant** changes color during gameplay. It is recommended to increase your **WETH** approval when **The Informant** turns <mark style="color:red;">**red**</mark> to keep you from **running into transaction errors** later. The Informant is a shadowy battledog that pops up once you've authorized approval. You can't miss it.

​

If you don't see this handy battledog, it means you are yet to authorize **approval of your** **WETH** for gameplay or you have exhausted your previous approval limit.

**This a prerequisite to play otherwise all gameable transactions will fail.**
