Sandbox · client-side · illustrative
Propose a trade. Watch it refused.
A pre-funded view of the control plane. Propose an order, move the price past its freshness limit, take the authority offline, flip the halt — and read every ruling in the book, refusals included.
No email or sign-up required. We never hold your keys. We never ask for your seed phrase.

What you just used
The same shape as the product. None of the money.
The sandbox runs entirely in your browser against an illustrative scenario. The live system rules, halts, and keeps its books the same way — with real venues, a real authority, and a customer’s own bounded permission.
- The ruling
- Decionis, the independent execution authority, ruling on each live order.
- The mandate
- A permission bounded by venues, actions, amounts, and an expiry of at most 90 days.
- The halt
- One action that stops all signing on an account, effective on the next request.
- The book
- A double-entry ledger, balances recomputed, drift from the chain displayed.
