It's time to refund affected users
Tonnel V4 Contract was a decentralised tool that allowed users to have hidden balances on TON blockchain, but there was a challenge back then on how to store the nullifiers in a sharded blockchain(like TON). It was a complicated case and the solution that we came up with unfortunately had a flaw that during the past 2 years no one noticed.
Unfortunately, with the current power of AI at analysing complex code(even in a divine language like funC), I no longer think publishing your code fully open source is viable and sensible.
Anyway, our mixer had ~3500 transactions in the past 2 years and I have no way to check your private balance. Please open zk2fa.tonnel.network and import your shield key there and create a proof of balance report and send the file to @tonnel and after reviewing I will make the full refund within a few days.
I apologise for the damage that TONNEL holders realised because of my mistake.
PS: As I expected the AI hacker was apparently a faggot and decided to bridge the money out of TON blockchain.
