I have noticed a problem with the TX fee. When I completed the mix I put 0.00008btc as the fees for my transaction but when I received the transaction it was only 0.00002btc. That wasnt a big problem since he transaction confirmed in a few minutes but I think something is anyway wrong.

It seems like the NoJS on your FAQ is broken.

When going through the mixing process, the delay has to be in round hours. I've tried having a delay for 16.7 hours, but it's rounded down to 16 hours. This doesn't help with privacy, and I would change it to allow selection by the minute. I've sent my funds to be mixed with a delay, and will update my post once I receive the funds.

Wish you all the best with your project

I received the mixed coins without delay with 0.3 % fee

1.I like design
2.Did not tried to use TTX fee, but looks like very useful will use it in future
3.Mixing was done without any matches with input wallet, got my coins

I want to wish you luck and will use your mixer , thank you very much for bounty,will tell more about TTX fee with next mixing.

Another new mixing service? Why not, free to test, here's my address: bc1q2aj8jasgscv0982dc7u4uvd7gjr2afdn6u8dfs. PM when done, in case you send and expect a test quickly. I don't always check my wallet, but if you don't mind waiting, within 48 hours for sure after confirmation.

Assuming bech32 addresses are fine to enter in the "receive mixed coins" to? Does the "delay" option affect time of tx or tx fee?

A few suggestions:
- There should be a QR code of the deposit address showing at the mixing page;
- There should be an option to randomize a delay for each output;
- You should also allow costumers to choose a more customizable fee (e.g 0.0.00007523);
- You should also allow costumers to choose their transaction fees is sat/byte instead of plain satoshis;

Also, what happens if a transaction stays unconfirmed for more than 24 hours and the session expires?
