Why would you need fixes? Earlier today you told us you were "not vulnerable."
What happened?
XDN is not vulnerable like XMR, due to high developers professionalism.
duckNote is not vulnerable for double spend attack, because XDN do not have any blockchain split, but Monero has it for more than 10 hours, that is why:
Monero is still vulnerable for double spend attack!

Also duckNote devs "fixed" this Monero-Bug more than 2 hours ago.
Hats off dNote.
I'm proud that I'm a part of XDN community.
