There will be a public burn address available on the Signatum block explorer, in plain view for everyone to see and follow. If you know how many coins are swapped/burned, a quick division by 4 will give you the total number of STRAKS of the dedicated swap supply (which you can follow transparently on the rich-list, it carries the tag "swap") that is distributed to SIGT coin-holders during the swap period. The Signatum burn address and the STRAKS addressed dedicated exclusively for the swap, have to match up at a ratio of 4:1, if not then you know there is an issue. No STRAKS from that address can be given out during that 30-day period without the required swap amount from Signatum matching it.

Any coins that remain unswapped at the end of the 30 day swap-period, we have communicated clearly and transparently will be split 40/60 between the treasury fund (to pay for ongoing operational expenses - which will also be made public - like the listing fee coverage from the donation fund was today) and air-drops.

When there is full transparency, there is zero chance of any of those scenarios happening, that you are concerned about.
