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.
Your key never leaves your wallet
Astryum prepares every transaction UNSIGNED. Signing always happens in your wallet — Xaman, MetaMask — 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 custody — we can’t custody
There is no deposit, no account to open with us, no balance “at Astryum”. Your capital lives in your wallets and in the protocols. If Astryum vanished tomorrow, everything remains yours and operable without us.
Zero discretion
Nothing moves without a condition you signed beforehand. Protections are deterministic rules; the agent only prepares what you ask — 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.
We are structured not to be a CASP — a crypto-asset service provider under the European MiCA law. By design: we hold no custody, we never touch client money, and nothing executes without your signature. Our position is deliberately stricter than most of the industry’s.
The activities MiCA reserves for authorized entities — like moving between euros and crypto — go through partners licensed for exactly that, never through us. Astryum stays where it can prove its boundary: observe, prepare, and hand you the signature.
We are the two halves of the problem we set out to solve. One of us operates in DeFi daily and knows precisely where the tooling falls short. The other was kept out by exactly that: he holds and little else, because using DeFi 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.
The project’s technical judgement and the source of most of its ideas. He operates in DeFi daily — open positions, real risk — and every architectural decision comes from there: the XRPL and Flare networks, 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.
Designs the interface and brings the ideas down to earth. He is not an advanced DeFi user: 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.
Astryum submits to public evaluation in the Flare and XRPL builder programs — judged, in the open. A scam doesn’t submit to that.
And the honest part: this is early access. Some things run on mainnet today and some aren’t there yet — and we’d rather tell you ourselves than have you find out. What isn’t there isn’t promised.
