Signatures and playing without signatures

What a signature is

A signature is your “yes” to one specific action: register, deposit tokens, make a spin, withdraw. The site only prepares the action; the Solana network carries it out — and only after you confirm it in your wallet. The site never sees and never asks for your secret phrase: the wallet signs by itself and hands the site only the finished signature. Every signature costs a small network fee in SOL, so keep a little SOL in the wallet at all times.

The wallet window: what's in it and how much time you have

When you press the spin button, the wallet shows a window with the action and “Confirm” and “Reject” buttons. One thing matters: the action has a shelf life — about a minute. If you confirm later, the network will no longer accept it. The site knows this: it prepares the action again and shows the window once more — just confirm a second time; the stake will not be charged twice.

Sometimes the wallet shows a warning like “Transaction failed simulation” — that is its own preliminary check, and it can be a false alarm when the network is busy. If the spin went through after you confirmed and the balance changed — all is well. If not — wait a few seconds and retry. You can always reject the window: nothing happens without your signature.

Playing without signatures: one signature for a day

Under the spin button in every game there is a “⚡ Play without signatures” button. You sign one action — and for 24 hours spins run without the wallet window: they are signed by a temporary key that lives only in your browser. This is the main and most convenient way to play.

• What the temporary key can do: only make spins, and only within the budget (10,000,000 FAIRDRUM) and the time limit. It cannot withdraw tokens, deposit them or change the wallet — that is written in the contract.
• What it costs: when you turn it on, 0.05 SOL leaves your wallet for network and oracle fees — enough for about 25 rounds. The remainder is shown on the session bar; when it runs low, a “top up” button appears. Unspent SOL is returned when the session is closed.
• How to turn it off: the “close” button on the session bar. A session also ends by itself after 24 hours, and the site returns the leftover SOL on your next visit.
• If something goes wrong (the key runs out of SOL, the time or the budget expires) — the game doesn't break: the site simply shows the usual wallet window for that spin.

Messages and what they mean

• “Node overloaded” / “node lagging” — the network can't keep up right now. Wait 5–10 seconds and retry; no money is charged in the meantime.
• “The transaction did not go through in time” — the network lost the action. Retry; if the stake did get recorded after all, the button turns into “Finish the spin” — press it, the result is not lost.
• “There is an unfinished spin” — the previous round is still being settled. Wait a couple of seconds or press “Finish the spin”.
• “Not enough SOL for the fee” — top up the wallet with SOL (0.01–0.05 is enough). How to do it: Wallet and SOL.
