Guest demo and a DevNet seat
| State | What you use | Where positions live |
|---|---|---|
| Browsing Trade without a seat | 10,000 paper credits | This browser; no Canton position |
| A leased guest seat | DevNet test credits | Contracts on Canton DevNet |
| A practice desk | Its own paper balance | The desk's practice record |
The Trade screen uses your seat after you connect. Paper credits do not turn into DevNet credits. Every balance here is for testing and has no cash value. See Balances for funding and pockets.
What the browser signs
The browser keeps a non-exportable ed25519 key in its local storage database. It signs requests that prove which seat is asking; the server submits the corresponding Canton commands. Your cash and ordinary positions name your party and the venue as stakeholders. The venue is still the counterparty and operates the demo parties' ledger access. Read the trust boundary before treating this as independent wallet custody.
Use on another device

Lease and reset
Seats come from a shared pool. The menu's countdown shows your current lease, which renews while you use it. If the pool is full, the page shows your place in line and waits for a free seat.
Reset seat deletes this browser's key. A holder reset releases the lease for cleanup; a joined device reset removes that device. Cleanup closes calls on still-trading Windows at their cost, including the fee, lets decided calls settle, and sweeps the remaining test credits before the party returns to the pool. The next visitor's history starts with their own lease.
Check Portfolio after an uncertain trade result before trying again. Status shows whether the venue and seat pool are answering.
