Who we are · and why you can verify it

At ASTRYUM, we don’t ask for trust.We prove it.

We are a small team building in the open. This page doesn’t ask you to believe us: it tells you what we cannot do with your money, who we are, and what exists — and what doesn’t — yet.

Why we can’t take your money

Your key never leaves your account

ASTRYUM prepares every transaction UNSIGNED. Signing always happens in your signing app, where you can read exactly what you authorize, operation by operation. No need to believe us: you see it at every signature.

We don’t hold your money — we can’t

We don’t keep your money: there is no balance “at ASTRYUM”. It lives in your accounts and on the platforms where you put it to work. If ASTRYUM vanished tomorrow, everything stays yours and works without us.

Zero discretion

Nothing moves without a condition you signed beforehand. Protections are fixed rules: ASTRYUM only prepares what you ask for; you review and you sign. Nobody here can decide for you, including us.

The best proof this isn’t a scam is not a badge: it is that, by architecture, there is no path for your capital to pass through our hands.

What we are, and what we are not

ASTRYUM is software: it holds nothing, executes for no one and decides for no one. What requires a licence is done by whoever holds one.

Who we really are

We are the two halves of the problem we set out to solve. One of us operates in decentralized finance daily and knows precisely where the tooling falls short. The other was kept out by exactly that: he holds and little else, because using that kind of finance today demands a level of detail that pushes away anyone who doesn’t live inside it. ASTRYUM comes from putting those two views together — the one who knows the terrain, and the one who shouldn’t need to know it to move his own money with confidence.

Eric
Eric
Co-founder · Architecture & protocol

The project’s technical judgement and the source of most of its ideas. He operates in decentralized finance daily — open positions, real risk — and every architectural decision comes from there: the networks ASTRYUM runs on, the unsigned transactions, and the boundary that keeps keys out of our reach. He knows what the tooling is missing because he misses it himself.

Guillem
Guillem
Co-founder · Product design

Designs the interface and brings the ideas down to earth. He is not an advanced user of decentralized finance: he holds and little else, because today’s complexity pushes away anyone who doesn’t live inside it — and that is exactly the standard he reviews every screen against. If something needs prior explanation to be understood, it isn’t finished.

The mission — that controlling all your finances fits in one single app that never custodies anything, and that using it with confidence takes no expertise: you see everything, you decide everything, you sign everything.

Built in plain sight

The code is in plain sight in a public mirror that anyone can read. ASTRYUM has been built since February 2026, in Andorra. See the code

And the honest part: some things already work, tested with our own capital, and some aren’t there yet. We’d rather tell you ourselves than have you find out. What isn’t there isn’t promised: it is stated with a date, or not at all.

“Money must always flow. When money is in motion, money works for you.”
