# Challenge #3 - Truster
More and more lending pools are offering flash loans. In this case, a new pool has launched that is offering flash loans of DVT tokens for free.

Currently the pool has 1 million DVT tokens in balance. And you have nothing.

But don't worry, you might be able to take them all from the pool. In a single transaction.
