The problem TT911 solves

The pools which were sitting idle in the private coin pools, now can be used through flashloans. And the fee collected for flashloans can make the withdrawals gasless.

Challenges we ran into

Integrating flash loans into privacy-based crypto mixers faced hurdles in balancing reduced fees without compromising user anonymity and security. Technical complexities, risk management concerns, and ensuring seamless integration without undermining the core features of the mixer were significant challenges. Moreover, aligning with the existing protocols and addressing potential misuse or exploitation required careful planning and collaboration with project developers.
