Hi, I have a query - I deposited coins to chipmixer and noted down what I thought was the correct voucher code - when I went back about 5 days later and restored my session with my session token it said that the voucher token was invalid?
So then I just withdrew the coins to electrum
Would these coins have been properly mixed?
thank you
Any withdraw from chipmixer means your funds would've been mixed.
I don't know why you've done this though. How long was your session open for? Vouchers survive longer than sessions do but it sounds like your session still holds your funds and you changed how you wanted to withdraw them (either by sweeping or exporting private keys).
In future, you should make a new session if you want to redeem a voucher or just restore your old session to spend funds (if you're within the week).
