A Swiss Stiftung is legally tied to its purpose, called “Zweck” in Swiss law. The assets “belong” to the Zweck/purpose. The board administers them. Tokenholders don't get a veto, Discord doesn't get a veto, and the council can't just rewrite the deed.
When the stated purpose no longer seems attainable or desirable, Swiss law gives you a few doors. Governed by Art.86, 86a, 88 and 85, they do different jobs.
Art. 86 ZGB is Zweckänderung - change of purpose. The board or the Aufsichtsbehörde files, and the competent federal or cantonal authority decides. This gets tested: has the original “Zweck” taken on a wholly different meaning or effect, then the foundation has plainly become estranged from the founder's will. The German language is sharper here. "Offenbar entfremdet." means the purpose still exists. It just no longer does what the Founder meant.
Art. 86a would let the founder reserve a rewrite, if they reserved it in the original file “Urkunde”. This can be done up to ten years since setup (or since the last founder-requested change). If the founder is a legal entity the right lasts 20 years after establishment. If the Stiftung is tax-exempt public good / charitable “gemeinnuetzig” under Art. 56 lit. g DBG, the new purpose has to stay public or charitable too. This can bite Foundations wishing to transition into a more centralized for-profit corporation like structure.
Art. 88 is concerned with the “Aufhebung”. The dissolution. The authority can do it on application or of its own accord. Either because the Zweck has become unattainable - and the foundation can’t be kept alive by changing the deed - or the Zweck has become unlawful or immoral.
It's important to notice the order inside Art 88. Purpose unattainable get checked first. An amendment second. Dissolution is a last resort.
Art. 85 sits on the side to the others. Organisational change instead of purpose change. This is usually an urgent matter, that preserves the assets or keeps the purpose realisable. The federal authority “Aufsichts” oversight applies, the board gets heard. This can be a way if the council is the issue.
This is where a lot of Web3 Stiftungen get stuck, imo.
If the deed says "promote blockchain / DLT / open networks" you can probably still do that after the token is down 99%, the lab left, or the DAO didn’t pass a meaningful proposal for months.
A broadly defined “Zweck” is a feature at setup which later becomes a trap. The purpose is still attainable, so invoking Art. 88 is closed. And Art. 86 wants estrangement from the founder's will. A successful decentralisation can be that (the Stiftung as a leftover office, still sitting on IP and runway). This has to be handled with nuance and care to not fall afoul of fines and regulations.
The actual work needing to be done is usually: read the original founding document, the “Urkunde” line by line. See whether you're still inside the existing purpose (interpretation, board resolution, maybe a tightened programme). See whether Art. 86a was reserved and the clock is running. See who the Aufsicht even is (ESA vs the canton of seat, often Zug).
Here, Mina's public runway / scale-down talk is a useful specimen. "The foundation should recede" is an Art. 86 / 88 question. Who files, with which authority, toward what leftover purpose, and where do the assets go if you actually dissolve.
