ABOUT US
We build the custody that was missing after FTX — without a conflict of interest, because the mathematics rules it out.
You should have to neither entrust your crypto assets to an exchange that can trade with them, nor carry the full weight of self-custody alone. Soveris holds exactly one of three keys and can move nothing alone. That is not a commitment on paper, but a property of the architecture.
WHY SOVERIS
After FTX, every serious investor knew: who can you still hand your assets to?
FTX, Celsius and BlockFi all broke the same promise — that your assets were safe with us — while in the background they traded with them, lent them out and pooled them together until nothing was left. Anyone who has seen that once never trusts an exchange blindly again.
The obvious answer is: then just hold everything yourself. But that only shifts the risk, it does not remove it. A lost recovery phrase, a robbery, a death with no provision — and everything is gone, without anyone having taken anything from you. Between Ledger and Fireblocks there was, for serious private wealth, nothing in between for a long time.
It is exactly this false choice that stands at the beginning of Soveris. No one should have to decide between „trusting a custodian" and „trusting only yourself". We build the tier that is missing in between — and we resolve the conflict not through a promise, but through the way it is built.
THE CONFLICT-FREE MODEL
We cannot make money from your assets — and that is exactly the point.
Zero conflicts of interest, with us, is not a pricing promise but a question of architecture. With only one of three keys we can neither trade nor lend nor move your assets. Today we fund ourselves through the subscription; further sources of revenue are not fixed — and they would change nothing about this structural guarantee.
ZERO CONFLICTS · STRUCTURAL, NOT A PROMISE
FOUNDER
The person who built regulated custody for the banks is building the non-custodial answer that makes the conflict unnecessary.
Marcel Nellesen, Founder
Marcel Nellesen has spent more than fifteen years working on platforms and financial technology. In recent years, as CPTO at Tangany, a BaFin-regulated custody platform, he built bank-grade crypto custody for Germany's banks and brokers. He therefore knows from the inside where custody fails — and at exactly which point it lets down the very person it was meant to protect.
You should never have to choose between „trusting a custodian" and „trusting only yourself".
He has held Bitcoin himself for six years and never accepted the two usual answers: neither full dependence on a custodian nor the full burden of self-custody. Soveris is the solution he wished for himself — a custody in which no one, Soveris included, can dispose of your assets alone, because a single key is mathematically not enough.
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 at someone's mercy nor alone
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 or audit — and open about where we stand today.
HOW IT STAYS CONFLICT-FREE
Three keys. Two are enough. One never is.
- 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) — You keep the third yourself, secured by your own passphrase, which we do not know.
2 of 3 to sign — with your two keys you can reach your assets at any time, even without us.
SOVEREIGN CUSTODY
What Degussa is for gold, Soveris is meant to be for digital assets.
A category of its own: sovereign custody in which the custodian simply cannot betray you.
EUROPEAN STANCE
At home in Europe, reckoned in euros, prepared for the worst case.
German GmbH, EU law
Soveris is a German GmbH under EU jurisdiction. Where you keep your assets, you should know whose law applies.

ESTATE SETTLED
Plainly said: not yet licensed
Soveris is software and MPC infrastructure, not a CASP under MiCA. We do not yet hold a licence or an audit — and feign neither. Before every transaction we warn you about suspicious recipient addresses; you decide. You can verify your holdings on your own addresses on the blockchain at any time.
