ABOUT US
After years of searching
The founding team brings years of experience from working at a BaFin-regulated crypto custodian, alongside deep knowledge and expertise in self-custody. And yet there was always the sense that the right solution — one that combines the best of both worlds — did not yet exist.
WHY SOVERIS
Not your keys, not your coins.
After the major collapses and scandals at large crypto platforms, the consensus was clear: not your keys, not your coins — so, self-custody. Because who is left to entrust your wealth to?
But that only shifts the risk; it does not make it disappear. A lost recovery phrase, a break-in, a death with no provision — and everything is gone, without anyone having taken a thing from you. For serious private wealth, there was nothing between a Ledger or a Bitbox and custody on Binance or Kraken.
It is exactly this false choice that stands at the beginning of Soveris. No one should have to choose between blind trust and trusting only themselves. We build the tier that is missing in between — and we resolve the conflict not through a promise, but by design.
THE CONFLICT-FREE MODEL
We cannot turn your wealth into our profit
Zero conflicts of interest is not a promise here — it is a question of architecture. With only one of three keys, we can neither trade, nor lend, nor move your assets.
ZERO CONFLICTS · STRUCTURAL, NOT A PROMISE
FOUNDER
From regulated custodian to the perfect self-custody solution
Marcel Nellesen, Founder
Marcel has worked on platforms and financial technology for more than fifteen years. In recent years, as CPTO at a leading BaFin-regulated crypto custodian, he built a crypto platform for major banks, brokers and crypto exchanges. He knows every detail, every advantage and every drawback, every risk and how to mitigate it.
You should never have to choose between "trusting a custodian" and "trusting only yourself".
For years he heard the same conflict across the industry: the risk of carrying everything yourself with self-custody, and the trust problem ("not your keys, not your coins") with central custody. At some point he could accept neither full dependence on a custodian nor the full weight of self-custody. Soveris is the solution he wished for himself — custody in which no one, Soveris included, can dispose of your assets alone, yet where the established controls of institutional custody still provide the security that self-custody on a hardware wallet cannot.
That Soveris starts self-funded is part of this stance. A custody brand that has to earn its money from the trust of its customers develops a different discipline than one that serves someone else's growth targets. No investor behind us demanding growth at any cost — in custody, that very calm is the difference.
Neither exposed nor on your own
You depend neither on the good behaviour of a custodian nor carry the whole risk yourself — both are built into the architecture.
Self-funded, on purpose
No outside capital, no pressure to grow. Our discipline comes from being carried by our customers — no one else.
Open about what we build
Founded in June 2026, still in the build phase, without a licence — and open about where we stand today.
THE SOLUTION
Three keys. Two are enough.
- PRIMARY (you) — You carry the first key on your device, released by your fingerprint or face.
- SECONDARY (Soveris) — We hold the second in a secured hardware module — it alone moves nothing.
- BACKUP (you) — We keep the third for you, but only the version encrypted with your passphrase, which we can do nothing with.
The crux: No one alone has 2 of 3 within direct reach. You hold the PRIMARY, we hold the SECONDARY — that is enough for everyday use. Only you can use the backup, yet you do not hold it directly. We release it only under clearly defined rules, to make you independent of us and to put you in control.
SOVERIS STANDS FOR
SOVEREIGN CUSTODY
A category of its own: sovereign custody in which no one can betray you.
