The demo, in writing.
What this phase is, what its risks are and how every transaction is built — published so you can review it whenever you want, with an account or without one. We would rather tell you ourselves than have you find out.

The risks, unsoftened
Experimental software
Astryum is in a public validation demo phase. It may contain bugs, be temporarily down, or leave an operation half-done. It is provided "as is", with no guarantee of availability or correct operation.
Real money, under caps
The demo operates with real XRP on mainnet. That is why the strategy rails carry a per-operation cap and a daily volume limit, and the dashboard shows how much of it you have used. The caps bound what a failure can expose while we validate; they are part of this phase by design, not an optional setting.
You sign everything — and it is irreversible
You sign every operation yourself, in your wallet. A signed transaction is irreversible by design of the chains. We do not hold your keys and have no way to — the server aborts start-up if it finds a raw EVM private key in its environment — so we cannot move, freeze or recover your funds. Always review before signing.
No guarantee of execution or timing
When you convert XRP into FXRP, your signature commits the exact hash of the operation and an executor — a role defined by the Flare protocol, operated today by Astryum — delivers the proof to the contract. That executor decides nothing: it either executes exactly what you signed, or the chain rejects it. But if it fails (network down, budget exhausted), your XRP can be temporarily parked without completing. We detect that situation automatically and the cap bounds the exposure. Still: this demo can fail and leave an operation half-done, and by using it you accept that risk.
None of this is advice
Astryum gives no financial, investment, tax or legal advice. The yields you see are protocol data, with their source — never a promise or a recommendation from us. Options are shown complete and unranked by convenience. The decision is always yours.
Destination protocols are third parties
The positions you open live in third-party protocols (Kinetic, Firelight, SparkDEX and others), with their own contracts, their own risks and their own terms, which apply to you. Astryum integrates them as execution venues; it does not operate them and does not answer for them.
Rules prepare — they never sign, and they are no insurance
The rules you configure (protections, harvests, scheduled moves) prepare transactions when your condition is met — they never sign or send them: they reach you, at the wallet that owns the position, for you to sign. No automation has discretion: the system picks no amounts, destinations or timing outside the parameters you set. We do not guarantee a rule fires on time or beats the market: if our systems are down when your condition is met, the prepared transaction may arrive late or not at all, and the position risk remains yours. On accounts governed by several signers (a council), an order only leaves with the quorum you configured on-chain; that order carries a 0.2 XRP service fee paid at the moment of signing — not when the proof is delivered afterwards — and visible before you sign: if the later delivery fails, the fee is already paid.
Your data, and what the chain makes indelible
Your acceptance of these terms is recorded with the text version and date — when you create the account, and also on entering the dashboard if you signed in with a wallet or if we change a text materially. What you sign is published on public chains forever — neither we nor anyone can erase it — and, to complete certain operations, operational accounts of ours publish transactions referencing yours: anyone analysing the chain can see your address operated through Astryum. The full detail of what we process, who receives it and how to exercise your rights lives in the Privacy notice.
Liability: capped at €50, with the legal carve-outs
Within the limits the law allows, our total liability for this demo is capped at €50. The demo has no subscription or access cost; the only fees that exist are shown before you sign. This cap does not apply in cases of wilful misconduct or gross negligence, nor where consumer law does not allow limiting it — nothing on this page limits rights the law grants you as a consumer. Nor do we answer for third-party protocol behaviour, price movements of your assets, decisions you make with the information we show, or the unavailability of networks, nodes or third-party wallets.
By creating an account and using the demo you confirm you understand and accept these risks. Nothing on this page limits rights the law grants you as a consumer.
The rules of use
Adults only
The demo is for people 18 or older. By creating an account or accepting these terms you declare that you are. We do no identity verification in this phase — which is exactly why we ask and record your declaration; if you are a minor, do not use the demo.
Where it cannot be used from
The demo cannot be used from territories under international sanctions (among others: North Korea, Iran, Syria, Cuba, Russia, Belarus and the regions of Crimea, Donetsk and Luhansk), nor by persons on sanctions lists. By using it you declare that this is not your case. We do not geoblock by location today — you declare the region you operate — so this rule works by declaration, and we tell you so plainly. Destination protocols additionally impose their own territorial restrictions in their terms, which apply to you when you use them.
We can suspend accounts — your capital is untouched
We can suspend or close an account for service abuse, fraud, breach of these rules or legal requirement. And here the architecture works in your favour: since we never hold custody, suspending an account never withholds your money — your capital stays in your wallets and in the protocols, operable without us.
Your taxes and use of the service
Tax obligations arising from your operations are yours: we do no tax calculation or withholding. The demo is offered for your personal use; attacking the service, probing it for vulnerabilities without telling us, or using it for unlawful activity is not permitted. The Astryum name and content belong to the operator; the code published in our repository keeps the license that accompanies it.
How every transaction is built
The full circuit, reviewable: from your intent to the chain, without any key of yours touching our servers.
It is prepared — unsigned
Astryum prepares your action as an UNSIGNED transaction: which contract it touches, which function it calls, with which parameters. The full transaction is yours before any signature exists.
It is simulated and shown
Before it reaches your wallet it is shown to you whole: expected effect, costs (including the executor fee, set by the protocol, not by Astryum) and the checks it passes. On the Flare strategy rails and on council orders it is additionally simulated against the chain before you sign. No surprises, no small print.
You sign — or nothing happens
Signing happens in your wallet (Xaman on XRPL, your EVM wallet on Flare), where you can read exactly what you authorize. In XRP→Flare flows, your signature commits the exact hash of the whole operation: neither we nor anyone can alter a byte without the chain rejecting it.
The chain is the receipt
Every settled operation is recorded on-chain with its public receipt, verifiable by anyone on the XRPL and Flare explorers — and published on our live transparency feed.
We don't ask you to believe us.
Operations executed through Astryum are published live, each with its receipt verifiable on the public XRPL and Flare explorers.
